What is the answer 4x+10=-26
Feliz [49]

Answer: x = -9

Step-by-step explanation:

Subtract 10 from both sides:

4x + 10 - 10 = -26 - 10

Simplify:

4x = -36

Divide both sides by 4:

4x/4 = -36/4

simplify:

-36/4 = -9

A coin-operated machine sells plastic rings. It contains 6 yellow rings, 11 blue rings, 15 green rings, and 3 black rings. Suzy
aleksandrvk [35]
1) you have to add all the rings together to find the denominator

6 + 11 + 15 + +3 = 35

2) the numerator is the amount of rings of the certain color you are trying to find the probability of

15

3) find the theoretical probability! 15/35

4) simplify

15/35 (divide both by 5) = 3/7

NeX [460]

Answer:

$90

Step-by-step explanation:

Given data

Given data

Loss= $13.5

Percentage of the loss= 15%

Let the full loss be x

Hence we can find the value of x as

15/100*x= 13.5

0.15x= 13.5

divide both sides by x

x= 13.5/0.15

x= $90

Hence the loss in full is $90
