18 is repeted in the y-axis
His present age is 13 years.
<h3>How to solve words problems ?</h3>
The words problem can be solved as follows:
let
his present age = x
Therefore,
3(x + 5) = 54
Hence,
3(x + 5) = 54
3x + 15 = 54
subtract 15 from both sides
3x + 15 - 15 = 54 - 15
3x = 39
divide both sides by 3
3x / 3 = 39 / 3
x = 13

Answer:
B
Step-by-step explanation:
"at least 50" includes 50 as a possibility, which means it would be
Because the two triangles are similar, one is a scaled down version of the other.
You can figure out that scale by comparing two matching sides, in this case AD and AB.
AD = 2 and AB = 2+4 = 6
So 2/6 = 1/3, telling us each side of the smaller triangle is 1/3 the size of the original.
Now we need to find ED and know CB = 12. Knowing ED = 1/3 of CB:
ED = 1/3 • 12 = 4
(-15x-3)+(7x-6)+(-2x+9)=-15x-3+7x-6+(-2x)+9=-15x-3+7x-6-2x+9=-10x
