Answer:
Step-by-step explanation:
X/7=3/2 multiply by : 5
x = 21/2
If you were to use the substitution method to solve the following system, we need to write one of the equation to an <span>expression equivalent to y. Let us say the second equation, we write it as follows:
</span><span>6x – 3y = –3
-3y = -6x - 3
y = 2x + 1
We substitute the equation to the first given equation as follows:
</span><span>2x – 5y = –3
</span>2x – 5(2x + 1) = –3
2x - 10x - 5 = -3
-8x = 2
x = -1/4
y = 2(-1/4) + 1 = 1/2
I believe that would be 49
Answer:
Step-by-step explanation:
Part a - triangles EGD and FGD are similar
part b - we know this because they have the same interior angles. both are 45,45,90 triangles
