Which expression represents the number of feet that are in x yards?
The conversion fact is 3 feet = 1 yard.So
1 yard = 3 feet
2 yards = 2(3 feet)
3 yards = 3( 3 feet)
Thus, x yards would equal 3x feet....
Answer: C. 3x
For A B and C, you just plug in the given number
A
![2(15) + 5 = 35](https://tex.z-dn.net/?f=2%2815%29%20%2B%205%20%3D%2035)
B
![4(20) + 2 = 82](https://tex.z-dn.net/?f=4%2820%29%20%2B%202%20%3D%2082)
C
![6(10) + 5 = 65](https://tex.z-dn.net/?f=6%2810%29%20%2B%205%20%3D%2065)
And for D, you set the equation to 26 and solve for n
![3x + 5 = 26 \\ 3x = 21 \\ x = 7](https://tex.z-dn.net/?f=3x%20%2B%205%20%3D%2026%20%5C%5C%203x%20%3D%2021%20%5C%5C%20x%20%3D%207)
I had to use x instead of n, but for D n=7. :)
Answer:
Step-by-step explanation:
y+ 20= x+ 15( Vertically opposite angles)
y+ 20- 15= x
x= y+ 5 __(1)
3x+ 5=4y- 15
Substituting (1)
3(y+5)+ 5= 4y-15
3y+15+5=4y- 15
y=15+20
y= 35
x= 40
