Answer:
7) a= 20
8) m= 5
9)n = 5
10) b = 8
Step-by-step explanation:
7) 18+2=-2+2+a
>> 20 = a >> a = 20
18 + 2 = 20 so that isolates the variable leaving a = 20
8) -7+12 = m -12+12
>>> 5 = m >> m = 5
-7 + 12 = 5 so that again isolates the variable leaving m = 5
9) <u>-8(7</u> + <u>7n</u>) = -336
>> -56+56 + -56n = -336+56
>>> -56n/-56 = -280/-56
>>>> n = 5
use distributive property, cancel out necessary numbers, isolate the variable. leaving n = 5.
10) -140 = <u>-7(-4 </u>+ <u>3b)</u>
>> -140 = 28 - 21b >> -140-28 = -21b +28-28 ( flipped the numbers)
>>> -168/-21 = -21b /-21
>>>> 8 = b >> b =8

Answer:
1/2-3/2=1 or -2/2=1 or -1=1
Step-by-step explanation:
q=-h-1
h-(-h)=1
h+h=1
2h=1
h=1/2
q=-1/2-1
q=-3/2
1/2-3/2=1
Answer:
The sales associate earns $13 a suit and $8 for a pair of shoes.
Step-by-step explanation:
Hello!
To find the answer, we will multiply the probabilities of both cars needing oil change, and tire rotation and oil change.
3/5 need an oil change.4/7 of the 3/5 need the tire rotation. We multiply these two numbers giving us 12/35, which is our answer.
There is a 12/35 chance that a car the comes in will both an oil change and a tire rotation.
Hope this helped!
