Answer:
-2 or -5
Step-by-step explanation:
(2x − 8) / (x² + 7x + 10) is an invalid expression when the denominator is 0.
x² + 7x + 10 = 0
(x + 2) (x + 5) = 0
x = -2 or -5
4/3 = x/21
So you can cross multiply and divide:
3x = 84
x = 28
Or you can say 3 times what equals 21? The answer is 7. Then multiply 4 times 7 to get the answer. Whichever makes more sense to you :)

Answer: 0.875 = 7
/8
Explanation:
Fractions, decimals and percents are all different ways of writing the same value. They are interchangeable.
3 decimal places means you working with thousandths.
0.875 = 875
/1000
You can now simplify by 5, or 25, or 125.
Dividing top and bottom by 125 simplifies in one step.
875
/1000 ÷ 125
/÷ 125 = 7/
8
It is a huge advantage to know some of the common fractions and decimals by heart. These include the eighths.
1/8 = 0.125
3/8 =0.375
5/8 =0.625
7/8 = 0.875
