Hello.
The solutions found to radical equations are not necessarily viable. They sometimes result in inequalities, and have to be checked.
Hope I helped.
Answer:
6) x = 40.5
8) x = 16.5
Step-by-step explanation:
6) 45/x = 20/18
simplify and cross-multiply to get:
45/x = 10/9
10x = 405
x = 40.5
8) 22/8 = x/6
11/4 = x/6
4x = 66
x = 33/2
x = 16.5
Given:
The descriptions and equations. The equations are


To find:
The correct description for each equation and match them.
Solution:
We know that, "+" is used for more and "×" is used for times.
Additive: y is 4 more than x.

Additive: x is 4 more than y.

Multiplicative: y is 4 times x.

Multiplicative: x is 4 times y

Therefore, the correct description for the equation
is "Multiplicative: y is 4 times x
" and the correct description for the equation
is "Additive: y is 4 more than x.
"
If it’s 5 times you would multiply 8000 x 5 which is 40,000.
