4x-10=2
add 10 to each side (addition property of equality)
4x-10+10=2+10
simplify
4x = 12
divide by 4 (division property of equality)
4x/4 = 12/4
simplify
x=3
Answer:
x = 55
y = 45
Step-by-step explanation:
In similar triangles, the ratio between similar sides are the same. So,
AB/ED = BC/EF = AC/DF
Substitute values that they give
6/15 = 18/y = 22/x
Solve 6/15 = 18/y by cross-multiplying
6y = 15*18 = 324
Divide both sides by 6
y= 45
Solve 6/15 = 22/x by cross-multiplying.
6x = 22*15 = 330
Divide both sides by 6.
x = 55
Because there is some dispute between the answers, let's check the ratios.
6/15 = 18/45 = 22/55
0.4 = 0.4 = 0.4
True, x = 55 and y=45
Let's called the number we're searching for x.
We have 1/3=x/16. Multiply by 16 on both sides : x=16/3
Answer:
