Answer:
z/6 +2=-18
z/6=-18-2
z/6=-20
z/6 *6=-20*6 we multiple both sides with 6 to remove 1/6 from z
z=-120
Answer:
After 10 years the investment A will be bigger than investment B.
Step-by-step explanation:
In Investment A, 50 increases each year by 8% and in investment B, 60 increases by 3 each year.
If after x years the investment A will be equal to investment B, then we can write the equation as

⇒ 50 + 4x = 60 + 3x
⇒ x = 10
Therefore, after 10 years the investment A will be bigger than investment B. (Answer)
X+5=8
x+(-7)=-4
4+x=7
7-x=4
3-x=0
-9×x= -27
those are just a few options
Solve it like an equation
4x-7>1
+7 +7
(-7+7)= 0 They cancel each other.
(1+7)=8
4x>8
/4 /4
(4/4) Cross it out, since they are both the same number. So, you stay with x.
(8÷4)= 2
You get x>2
Answer:
If Father is four times older than Mary, that would be 4 times 10-- which equals 40. Five years ago, Mary must have been 5 years old. So, multiply 7 and 5 and you'll get 35! Father would have been 35 years old.
I hope this helps!
