Answer:
She is 40 years of age
Step-by-step explanation:
Let Joaquin age be j
Let Marjorie age be m
From the first part of the question;
j = 4 + m/2
Secondly;
m =3j - 32
Multiply equation i through by 2
2j = 8 + m
m = 2j-8
Equate both m
2j-8 = 3j-32
3j-2j = 32 -8
j = 24
m = 2j-8
m = 2(24)-8
m = 48-8
m = 40

An engineer designed a new bridge and drew the scale drawing shown below. 6 Inches If the engineer used the scale 3 inch = 40 feet, how long is the actual bridge the engineer designed?
Answer:
The bridge is 80 feet long
Step-by-step explanation:
We will use the ratio method to solve the question
∵ The engineer used the scale 3 inch = 40 feet
∴ The scale drawing is ⇒ 3 inche : 40 feet
∵ The drawing length of the bridge is 6 inches
→ By using the ratio method
→ inch : feet
→ 3 : 40
→ 6 : x
→ By using cross multiplication
∵ 3 × x = 6 × 40
∴ 3x = 240
→ Divide both sides by 3
∴ x = 80
∵ x represents the actual length of the bridge
∴ The bridge is 80 feet long
The value of a new car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was $1,500? If you get stuck, consider using diagrams or a table to organize your work.
Answer:
After one year, the car will be worth $1,275.
Step-by-step explanation:
We know that a new car value decreases by 15% every year. So, we first need to find 15% of $1,500.
1,500 x 0.15 = $225.
Now, me must subtract $225 from the initial value, or $1,500.
1,500 - 225 = $1,275
Therefore, after one year, the car will be worth $1,275.

(0,0) (-4,-4) (2,-4) graph the image of this triangle after a dilation with a scale factor of 2 centered at the origin
Answer:
The image coordinates are:
A'(0, 0)
B'(-8, -8)
C'(4, -8)
The graph of the image coordinates attached below.
The image triangle A'B'C' is illustrated in green color.
Step-by-step explanation:
Let the points of a triangle be
A(0,0) B(-4,-4) C(2,-4)We need to determine the graph of the image of this triangle after a dilation with a scale factor of 2 centered at the origin.
As scale factor > 0, thus the image will be enlarged.A dilation by a scale factor of 2 centered at the origin means the coordinates of the image can be obtained by multiplying the original coordinates with 2.
Next, the rule of dilation by a scale factor of 2 is given by
Dilation: (x, y) → (2x, 2y), centered at (0, 0)
P(x, y) → P' (2x, 2y)
A(0, 0) → A' (2(0), 2(0)) → A'(0, 0)
B(-4, -4) → B' (2(-4), 2(-4)) → B'(-8, -8)
C(2,-4) → C' (2(2), 2(-4)) → C'(4, -8)
Therefore, the image coordinates are:
A'(0, 0)B'(-8, -8)C'(4, -8)The graph of the image coordinates attached below.
The image triangle A'B'C' is illustrated in green color.

Answer:
A = The greatest common factor would be 9.
B: 45+63= 9*(5+7)
Step-by-step explanation:
Answer:
b is 45+63=9(5+7)
Step-by-step explanation:
Once you know the GCF, you just need to find what the GCF (9 in this case), times what will get you 45 and 63. So we already know that 9 will be on the outside of the parentheses since it's what we're multiplying by. 9 times 5 is 45, so for the first number in the parentheses you'll put 5, and for the second, 9 times 7 is 63, so the second number in the parentheses is 7. You can check by solving it. 9(5+7). Use the distributive property and first you will do 9 times 5, which is 45, then 9 times 7 which is 63, so you'll get 45+63, which is correct.

HURRY!!!! A summer camp is providing breakfast for 350 children that includes a 6 ounce serving of sausage per student. The camp can only purchase sausage in whole 1 pound packages. Note: 1 pound = 16 ounces? PLEASE I NEED HELP
Answer:
132 whole 1 pound packages.
Step-by-step explanation:
6 ounces times 350* equals 2100 ounces, so the summer cap needs 2100 ounces of sausage to feed all 350 children. We already know there are 16 ounces per pound. 16 x 131 equals 2096. Remember, it takes 2100 ounces to feed all 350 children. The summer camp will have to buy 132 packages to exceed 2100 without having additional whole packages.
*this number represents the amount of children
The camp needs to buy 132 packets of sausage to serve 350 students.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, A summer camp is providing breakfast for 350 children that include a 6-ounce serving of sausage per student.
So, The total amount of sausages is,
= 6×350 ounces.
= 2100 ounces.
Also given, sausages come in 1 pound pack.
Therefore, The number of packets required is,
= (2100/16).
= 131.25 but they have to buy 132 packets.

Nancy has to mark the point with the coordinates (-2, 4) on the coordinate plane. Which point in the graph is at (-2, 4)? In which quadrant is the point located?
Answer:
Point A at Quadrant 2
Step-by-step explanation:
For point (-2, 4) the -2 is the x-axis and the 4 is the y-axis. All points at -2 on the x-axis are A, J, and K. All points at 4 on the y-axis are A, B, and C. Since point A is satisfies both of the places on the x-axis and the y-axis, your answer is point A.

Step-by-step explanation:
3x-2y=12 is the standard form of equation y=3/2x - 6
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The equation is y=3/2x - 6
y equal to three by two times of x minus six
y=3/2x - 6
LCM of 1 and 2 is 2
y=(3x-12)/2
Now apply cross multiplication
2y=3x-12
Two times of y equal to three times of x minus twelve
Now take 2y to RHS side
3x-2y-12=0
3x-2y=12
Hence 3x-2y=12 is the standard Form of equation y=3/2x - 6.

Answer:
The sum of the interior angle measures of the polygon is 540°
Step-by-step explanation:
The formula of the sum of the measures of the interior angles of a polygon is
∑m = (n - 2) × 180°, where n is the number of the sides of the polygon
In the given figure
∵ The polygon has 5 sides
∴ n = 5
→ Use the formula above to find the sum of the interior angle measures of it
∵ ∑m = (5 - 2) × 180°
∴ ∑m = 3 × 180°
∴ ∑m = 540°
∴ The sum of the interior angle measures of the polygon is 540°
