Y = 3x + 4
<span>2x + 3y = 10
</span>
We need to substitute the first equation into the second equation. So, we would substitute y in the second equation with 3x + 4.
2x + 3(3x + 4) = 10
This would be answer choice B. 2x + 3(3x + 4) = 10.
S = A - 17
A = 55
S = 55 - 17
S = 38 <=== Sandy has 38 cards
2(10)-2(6x)= x-8x
20-12x=x-8x
+12x+12x
20=13x-8x
20=5x
4=x
<span>The first part is already in squared terms. "19.25 sq ft"
Taking the measurements for the mirror 3ft and 5ft, you'd get: "15 sq ft."
Subtract that answer from the previous number to get "4.25 sq ft.
Hope this helps out a little lol :)</span>
Answer:
15 inches tall
Step-by-step explanation:
To solve I would set up a ratio to visualize the question.
x in : 90 ft
1 in : 6ft
Then divide... 90 ÷ 6 = 15 ( this is the inches in the ratio that compares to 90 ft).
