3(1/2x +4) = 2x +2
Use distributive property by multiply 3 by each term on the left side:
3/2x + 12 = 2x + 2
Subtract 12 from both sides:
3/2x = 2x -10
Subtract 2x from both sides:
-1/2x = -10
Multiply both sides by -2:
x = 20
Answer: x = 20
Answer:
Answer is - B) 27
Step-by-step explanation:
Total choices can be found as :
Either a soup or salad from 4 choices : 4
An entree from 5 offerings : 5
Two side dishes from 5 options : 5C2 = ![\frac{5\times4\times3\times2\times1}{2\times1\times3\times2\times1}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Ctimes4%5Ctimes3%5Ctimes2%5Ctimes1%7D%7B2%5Ctimes1%5Ctimes3%5Ctimes2%5Ctimes1%7D)
= 10
One of 4 dessert cakes : 4
So, total choices become : ![4\times5\times10\times4=800](https://tex.z-dn.net/?f=4%5Ctimes5%5Ctimes10%5Ctimes4%3D800)
And given there are 30 days in the month, so it becomes:
≈ 27
Answer:

Step-by-step explanation:
-5^2+8|-1|+(-3)
-25+8x1-3
-25+8-3
-17-3
-20
Answer:
20.
m = -52
22.
x=13
24.
a=-90
26.
n=-2
28.
a=9
30.
m=-10
Step-by-step explanation:
20. m/4=-13
m = -13*4 = -52
22. -143=-11x
x=-143/-11 =13
24. -5=a/18
a=-5*18= -90
26. n-8=-10
n=--10+8
n=-2
28. a+11=20
a=20-11
a=9
30. 18+m=8
m=8-18
m=-10
