the answer is x= 10.
the steps would go like this.
4 + 3/5 × (15 + 2x) = 25
4 + 9 + 6/5x = 25
13 + 6/5x = 25
65 + 6x = 125
6x = 125 -65
6x = 60
x = 10
hope this helps
Answer:

= 8 + 4
= 12
D
An easier way of doing it mentally is 3 x 25 which is 75 and then 1 x 25 which is 25
For volume of a prism, the general rule is multiply the area of the base by the area of the height. For example, for a triangular prism, the volume would be (1/2)b*h*a if you set a = height of the prism and h = height of the triangle from the formula (1/2)bh, which is the area of a triangle.
Answer:
x=2,y=2
Step-by-step explanation:
3y-1 = 5
or, 3y = 5+1
or, y = 6/3
y = 2
2x+1 = 3y-1
or, 2x = 3×2-1-1
or, 2x = 4
or, x = 2
