3x + 1 + 5x = 7 + 15 + 7x
8x + 1 = 22 + 7x
x = 21
Answer:
if 19/4 meter (assuming 4.75) of wire = rs, then (where w is a meter of wire)
4.75w = rs,
w = 4rs / 19
one meter of wire = 4rs / 19
Step-by-step explanation:
Answer:
Option C. 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
and
The scale factor is equal to the ratio of its corresponding sides
Let
z-----> the scale factor

simplify

Answer: x = 6
Step-by-step explanation: 2x - 5 = 7
+ 5 +5
2x/2 = 12/2
x = 6
