(Will give 15 points)Solve the system of linear equations by substitution. x + y = 7 and 7x + y = 1
Answer:
(-1, 8)
Step-by-step explanation:
Make y the subject:
x + y = 7 ⟹ y = -x + 7
1. Substitute the value for y into 7x + y = 1 and solve for x:
7x + (-x + 7) = 1
7x - x + 7 = 1
6x + 7 = 1
6x + 7 - 7 = 1 - 7
6x = -6
6x ÷ 6 = -6 ÷ 6
x = -1
2. Substitute the given value of x into x + y = 7 and solve for y:
x + y = 7
-1 + y = 7
-1 + 1 + y = 7 + 1
y = 8
Therefore, the solution to this system of equations is: (-1, 8).

Step-by-step explanation:
Add all the men together and then divide them by their number which in this case is 10.
Do the same thing to women add them all together and then divide them by their number which in this case is 11.
BTW I am doing a 100 point question come if you want points. The question is easy
Answer:
Men is 22.1
Women is 18
Step-by-step explanation:
You should add the numbers of the men and women separately, then divide each by the amount of numbers available.
In this case, you add the digits in Men, equaling 221, then divide them by 10, which will equal 22.1.
Let’s solve for Women, add the digits of women together, you’ll get 198, divide that number by 11, your answer would be 18.

I put in the question at the diagram of the angle
Step-by-step explanation:
<YOZ = 60°
When two lines intersect each other, then four angles are formed. The angles that are opposite to each other at the intersection point are known as vertically opposite angles. VERTICALLY OPPOSITE ANGLES ARE ALWAYS EQUAL.
If < VOX = 90⁰, then <VOW = 60⁰.
<VOW and <YOZ are vertically opposite angles.
Answer:
Step-by-step explanation:
Givens
<VOX = 90 degrees
<WOX = 30 degrees
<YOZ = ? degrees.
Solution
<VOW is the complement of <WOX
<VOW = <VOX - <WOX Substitute values
<VOW = 90 - 30 Subtract
<VOW = 60
<YOZ = <VOW Property of vertically opposite <s
<YOZ = 60 Substitute value
Answer
<YOZ = 60 degrees

Answer:
12 square units
Step-by-step explanation:
The answer might be a little easier to see if we slide that triangle on the left over to turn this shape into a rectangle! This is a technique you can apply to any parallelogram. Looking at the newly constructed rectangle, we can find its area by multiplying its length (2) and width (6) for an area of 2 · 6 = 12 square units.
Answer:
12 units squared
Step-by-step explanation:
Formula for area of a parallelogram:
A = b • h
The base of the parallelogram is 6 units. The height of the parallelogram is 2 units. Multiply the two numbers together. 6 • 2 = 12 units squared.
Which of the following are acute scalene triangles?
Answer:
Y and Z.
Step-by-step explanation:
My reasoning is that because scalene triangles have all different measurements, Y and Z would be correct since they have multiple different measurements. X is an obtuse triangle, while W is a right triangle, so that leaves Y and Z.
===========================================================
Explanation:
Triangle W is a right triangle because of the square marker. This angle is 90 degrees, also known as a right angle.
Acute triangles on the other hand must have all angles smaller than 90 degrees. This rules out triangle W.
The missing angle of triangle X is 180-40-35 = 105 degrees, showing this triangle is obtuse. Obtuse triangles have exactly one angle that is between 90 and 180. Therefore, we rule out triangle X as well.
Triangles Y and Z are acute because all angles are smaller than 90 degrees. For triangle Y, the missing angle is 180-70-80 = 30. For triangle Z, the missing angle is 180-65-45 = 70 degrees.
---------------
That takes care of the "acute" portion. Now onto the "scalene" part.
All four triangles shown are scalene. Why? Because all three sides are different lengths, as indicated by the different tickmarks.
However, we ruled out triangles W and X since they weren't acute.
Therefore, triangles Y and Z are both acute and scalene.A hybrid car can travel 484 miles on 11 gallons of gas. What is the unit rate in miles per gallon? (FIRST ANSWER GETS BRAINLIEST)

Answer:
35.28 cm³
Explanation:
Volume of triangular prism = Area of Base × Length
Find area of base of the triangle:
1/2 × base × height = 1/2 × 4.2 × 2.8 = 5.88 cm²
Then find volume:
A × L = 5.88 × 6 = 35.28 cm³
1/2 x 4.2 =2.1
2.8 x 6 x 2.1 =

Step-by-step explanation:
A book store is hosting a special night in which families can enjoy a story and craft time. Tickets to the
event must be purchased ahead of time and are $1.50 for children and $2.50 for adults. So far, 45
children's tickets have been sold, which is 60% of the total tickets sold. How many tickets have been
sold so far? Show your calculations or explain how you got your answer.
Answer:
75 total tickets
Step-by-step explanation:
METHOD 1:
We know that 45 children's tickets have been sold, being 60% of the total tickets having been sold.
So, basically, we solve for x:
We have, 60% × x = 45
or, 60/100 × x = 45
Multiplying both sides by 100 and dividing both sides by 60,
we have x = 45 × 100/60
x = 75
If using calculator, enter 45x100/60, which will give you the answer.
------------------------
METHOD 2:
Division is the opposite of multiplication
Start with the formula to calculate the percentage of total
y=value÷ percentage/100
Substitute values in the equation
y=45÷60/100
Simplify and solve
y=45÷0.6
y=75
Both methods give you 75, therefore 75 tickets have been sold

The table is filled out by following these steps:
Step 1) Pick any number you want for x. Usually small values work such as x = 0, but you can choose anything you want. Be sure it fits within the window of the graph.Step 2) Replace x with that number you picked. If you picked x = 0, then y = (1/3)x becomes y = (1/3)*0 = 0. Meaning x = 0 leads to y = 0. The point (0,0) is on the graph.Step 3) Go back to step 1 and repeat the process with other x values. I recommend picking multiples of 3 so you can avoid fractional values of y.Follow those steps listed above so you can fill out the table. Each row of the table generates a different (x,y) point on the graph. Then draw a line or curve through the points. In this case, it's a straight line.
This straight line has a slope of 1/3 because y = (1/3)x is in slope-intercept form y = mx+b where,
m = 1/3 = slopeb = 0 = y interceptA slope of 1/3 means "go up 1, over to the right 3" when hopping from point to point along the line.
The unit rate and slope are the same thing when it comes to linear equations.
Michael is making a card for his dad's birthday. He's shaded a triangular section on the card where he wants to write his dad a message. What is the area of the parts of the card that are not shaded?(sides are 12cm, 3,, 9 )
144
108
72
66
Answer:
Option c) 72 cm²
Step-by-step explanation:
In the figure attached we can see a rectangle ABCD with length 12 cm and width 9 cm.
A triangle PEF with height BE and base EF.
Since side AE = 3 cm, so side EB = EC = 9 - 3 = 6cm
and EF = AD = 12 cm
Now we will find the area of of the parts of the card that are not shaded.
Area of parts that are not shaded = Area of rectangle - area of shaded triangle
= (12×9) - 1/2 (BE)(EF)
= 108 - 1/2(6)(12) = 108 - (3)(12) = 72
Option c) 72 cm² is the area of non shaded part.

Answer:
2.25 cm³
Step-by-step explanation:
The volume of a pyramid can be found using the formula:
[tex] \boxed{\text{volume of pyramid= ⅓×base ×height}}[/tex]
Base area
= area of square
= side ×side
= 1.5²
= 2.25 cm²
Volume of paperweight
= ⅓(2.25)(3)
= 2.25 cm³
Find the volume of the cone. Round to two decimal places
Answer:
564.44
11*7 squared
Answer:
V = 564.15 ft^3
Step-by-step explanation:
The formula for the volume of a cone of base radius r and height h is
V = (1/3)(pi)(r^2)(h). Here, r = 7 ft and h = 11 ft, and so the volume of this particular cone is
V = (1/3)(3.14)(7 ft)^2*(11 ft), or V = 564.15 ft^3
