Solución 1: 2(x) + 3(y) = 80
solución 2: 3(x) + 2(y) = 70
3(y) + 2(x) = 80
2(y) + 3(x) = 70
2y = -3x + 70
y = -3x÷2 + 35
2x + 3(-3x÷ 2+35) = 80
-5x÷2 = -25
-5x = -50
5x = 50
x-intercept: 10
x = 10
y = -3x÷ 2+35
y = -(3÷2)(10)+35 = 20
x-interpcet: 10
y-intercept: 20
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
solución: x - 8y = 0
solución x + 4y = 480
-8y + x = 0
4y + x = 480
x-intercept (solución 2)
x = -4x + 480
x-intercept (solución 1)
4y + 180 - 8y = 0
-12y = 480
y-intercept: 40
x-intercept: 320
Buena Suerte!
1 yard = 3 feet
4 yards x 3 feet = 12 feet
12 feet is less than 13 feet
So False, 4 yards is <em>less than </em>13 feet
hope this helps

Answer:
1 solution
Step-by-step explanation:
The coefficients of d are different on the two sides of the equation (3d vs 6d), so the equation has one solution.
__
Dividing by 3 gives ...
d +11 = 2(d +33)
d + 11 = 2d + 66
Adding -d-66 to both sides gives ...
-55 = d . . . . . . the one solution

You need to find "two-fifths of 30." Of here means multiplication:
![\begin{aligned}\dfrac{2}{5}\cdot 30 &= \dfrac{2}{5}\cdot\dfrac{30}{1}\\[0.5em] &= \dfrac{60}{5}\\[0.5em] &= 12\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%5Cdfrac%7B2%7D%7B5%7D%5Ccdot%2030%20%26%3D%20%5Cdfrac%7B2%7D%7B5%7D%5Ccdot%5Cdfrac%7B30%7D%7B1%7D%5C%5C%5B0.5em%5D%20%26%3D%20%5Cdfrac%7B60%7D%7B5%7D%5C%5C%5B0.5em%5D%20%26%3D%2012%5Cend%7Baligned%7D)
