Sagot :
Answer:
1. x+9=-7
x+9-9=-7-9
x=-16
2.
[tex]5x = 20 \\ \frac{5x}{5} = \frac{20}{5} \\ x = 4[/tex]
3. 8-x=2
8+-x=2
-x+8=2
-x+8-8=2-8
-x=-6
-x/-1=-6/-1
x=6
4.x+3=17
x+3-3=17-3
x=14
5./x/=7
1.)
Simplifying
-7 + -1(-9) = 0
Multiply -1 * -9
-7 + 9 = 0
Combine like terms: -7 + 9 = 2
2 = 0
Solving
2 = 0
2.)
Explanation:
5% of 20 can be written as 5% × 20
= 5/100 × 20
= 1
Thus, 5% of 20 is 1.
3.)
What is 8 / 2 simplified?
4⁄1
What is 8 / 2 as a decimal?
4
What is 8 / 2 as a mixed number?
8⁄2 = 4
What is 8 / 2 spelled out?
eight halves
4.)
1x - 5 = 17
1x = 17 + 5
1x = 22 (divide both sides by 1 to get x)
1x/1 = 22/1
x = 22
5.)
Add 22 to both sides.
x=7+2
2 Simplify 7+27+2 to 99.
x=9
hope it help
thanks me later
