Answer:
right scalene
Step-by-step explanation:
there is a 90 degree angle, a right angle
also, none of the three angles/sides are congruent (the same)
Explanation:
It has the 90° box meaning it’s a right triangle, and also none of the legs are the same length meaning it’s scalene.

I sell cookies for $3 and muffins for $7. Yesterday, I made $129. I sold a total of 27 items. How many of each did I sell?
Answers
c - cookies
m - muffins
c + m = 27
3c + 7m = 129
I don’t know how to explain how to do efficiently but I just plugged in numbers until it worked:
3(15) + 7(12) = 129
45 + 84 = 129
Answer:
You sold 15 cookies and 12 muffins
Step-by-step explanation:
So you're given that 1 cookie is sold for $3 and 1 muffin is sold for $7
You're also given that in total you made $129, and sold 27 items
Let's make equations from that, letting c stand for amount of cookies and m for amount of muffins.
3c + 7m = 129 (equation for amount of money made)c + m = 27 (equation for amount of items sold)Now we can use the second equation to find m:
c + m = 27
m = 27 - c
Not we can substitute m into the first equation to find c:
3c + 7m = 129
3c + 7(27-c) = 129 [substitute m for (27-c)]
3c + 189 -7c = 129 [distribute 7 into (27-c)]
-4c + 189 = 129 [combine like terms]
-4c = -60 [subtract 189 from both sides]
c = 15 [divide both sides by -4]
Now we can substitute c into the second equation to find m:
c + m = 27
15 + m = 27
m = 12

2. Divide 2 1/2 by 28 1/4.
3. Multiply 28 1/4 by 2 1/2.
4. Divide 28 1/4 by 2 1/2.
Answers
Answer:

Step-by-step explanation:
you have to reverse the equation is A=lw then to get l you use l=A/w
Answer:
Divide 28 by 2
Step-by-step explanation:
When the variable of interest is multiplied by something, you undo that multiplication by dividing the equation by that something.
Here, l is multiplied by 2, so the solution is found by dividing ...
... 28 = l·2
by 2 to get ...
... 28/2 = l
That is, you divide 28 by 2 to find l.

Write the question, in slope-intercept form, for the line shown in the graph below:
Can some one pls help me in this math problem?

The question, in the slope-intercept form will be:
[tex]y=1(x)+0[/tex]Step-by-step explanation:
Taking the two points on the line to find the slope
(0, 0)
(4, 4)
[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(4,\:4\right)[/tex]
[tex]m=\frac{4-0}{4-0}[/tex]
[tex]m=1[/tex]
As the point-slope form is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
substituting the values m = 1 and the point (0, 0)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-0=1(x-0)[/tex]
[tex]y=x[/tex]
As the slope-intercept form is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
so writing the equation in slope-intercept form
[tex]y=x[/tex]
[tex]y=1(x)+0[/tex]
Therefore, the question, in the slope-intercept form will be:

Find the length of the shortest side ( rounded to 2DP) if the area of the rectangle is 28m^2
Answers
Answer:
4.39 to 2DP.
Step-by-step explanation:
x * (x - 2) = 28
x^2 - 2x = 28
Solving by completing the square:
(x - 1)^2 - 1 = 28
(x - 1)^2 = 29
x = +/-√29 + 1
x = 6.38516, -4.38516
x must be positive so it = 6.38516.
The shortest side = x - 2 = 4.385.

The equation of the line that passes through (−8, 0) is y = ???
Answers
Answer:
y = 5x/4 + 10
Step-by-step explanation:
If two lines are parallel, the slopes are equal
The equation of a straight line is y = mx + c
where m is slope and c is y-intercept
So in this case 5/4 is also the slope m of the second line
we can write the equation as;
y-y1 = m(x-x1)
y-0 = 5/4(x + 8)
y = 5x/4 + 10

Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerator by the reciprocal of the denominator.
Step-by-step explanation:
Simplifying an expression involves breaking down the expression.
The true statement is: (a) Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerator by the reciprocal of the denominator.
The expression is given as:
[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}}}[/tex]
Start by writing the numerator and the denominator, with a common denominator
[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{\frac{5 -4a +12}{a - 3}}{\frac{2a - 6 + 1}{a - 3}}}[/tex]
Cancel out the denominators of both fractions (by dividing the numerators)
[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{5 -4a +12}{2a - 6 + 1}}[/tex]
So, we have:
[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{17 -4a }{2a - 5}}[/tex]
Hence, the correct option is (a).

Step-by-step explanation:
Answer:
The equation of the line that passes through the points (-1,8) and (2,-4) is:
[tex]y=-4x+4[/tex]Step-by-step explanation:
Given the points
(-1,8)(2,-4)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:8\right),\:\left(x_2,\:y_2\right)=\left(2,\:-4\right)[/tex]
[tex]m=\frac{-4-8}{2-\left(-1\right)}[/tex]
[tex]m=-4[/tex]
As the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope.
substituting the values m = -4 and the point (-1,8)
[tex]y-\(8\right=-4\left(x-\left(-1\right)\right)[/tex]
[tex]y-8 = -4(x+1)[/tex]
Add 8 to both sides
[tex]y-8+8=-4\left(x+1\right)+8[/tex]
[tex]y=-4x+4[/tex]
