<u>Let's solve this problem step-by-step</u>
<u>Let's set</u>:
2x + 6y = 36 -- equation 1
x + 4y = 20 -- equation 2
(equation 2) * 2
2x + 8y = 40 -- equation 3
(equation 3) - (equation 1)
2y = 4
y = 2 -- equation 4
Plug (equation 4)'s value of y into (equation 2)
x + 4(2) = 20
x = 20 - 8
x = 12
<u>Thus x = 12 and y = 2</u>
<u>Let's check, by substituting these values</u>
<u>Answer: x = 12 and y = 2</u>
Hope that helps!
Answer:
Is D I think
Step-by-step explanation:
Answer:
M = 2620 + 16d
M = total money paid or earned
d = # of days
Step-by-step explanation:
15 food
23 game
Total Money = M = 15 * 75 + 9 d + 23* 65 + 7d
M = 15 * 75 + 9 d + 23* 65 + 7d
M = 1125 + 1495 + 16d
M = 2620 + 16d
Answer:
24 square centimeters
Step-by-step explanation:
How much space does the triangle cover? Triangle with a base of 4 cm and a height of 12 cm
We are to find the area of the triangle
Area of the Triangle = 1/2 × Base × Height
= 1/2 × 4 × 12
= 24 square centimeters.
Therefore, the triangle will cover a space of 24 square centimeters.
Answer:
22
Step-by-step explanation:
ST is y and SU is 2y-4.
Note that SU = ST + TU = y + 18
So we have 2y - 4 = y + 18
2y - 4 = y + 18
2y = y + 22
y = 22
So ST is 22.
