Solve for g
-6g + 3g + 12 > -18
A.g<2
B.g> 2
C.g<10
D.g> 10

Answers

Answer:

g < 10

Step-by-step explanation:

-6g + 3g + 12 > -18

Combine like terms

-3g +12 > -18

Subtract 12 from each side

-3g+12-12 > -18-12

-3g > -30

Divide each side by -3, remembering to flip the inequality

-3g/-3 < -30/-3

g < 10

three friends earned more than $200 washing cars. they paid their parents $28 for supplies and divided the rest of money equally. write an inequality to find possible amounts each friend earned. identify what your variable represents.

Answers

well on answer could be $238-$28=210 divided by 3 = $70 each
also another one is $208-$28=180 and then if u divide $180 by 3 u will get a awser of $60 each

16 is 20% of what number

Answers

WORK:
$(16)/(unknown)$ ÷ $(20)/(100)$
$(20)/(100)$ = $(2)/(10)$
(You get $(2)/(10)$ from $(20)/(100)$ by dividing the numerator and denominator by 10)
$(16)/(unknown)$ ÷ $(2)/(10)$ = $(16)/(80)$
You get $(16)/(80)$ because you multiply the numerator 2 by 8 to get 16, so you have to multiply the denominator 10 by 8 as well to get 80.
ANSWER:
16 is 20% of 80

16 is 20 percent of the number 80.

How to find percentage?

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100.

Therefore, let's find the number 16 is 20% of .

Let

x = the number

Therefore,

20% of x = 16

20 / 100 × x = 16

20x / 100 = 16

cross multiply

1600 = 20x

divide both sides by 20

x = 1600 / 20

x = 80

Therefore, the number is 80

A) 21
B) 27
C) 31
D) 34

Answers

Answer: A) 21

Step-by-step explanation:

From the given figure, we can see that angles $64^(\circ)$ and $(3x+1)^(\circ)$ are vertically opposite angles.

Since, vertically opposite angles are equal, therefore we have

$64^(\circ)=(3x+1)^(\circ)\n\n\Rightarrow64=3x+1\n\n\text{Subtract 1 on both sides, we get}\n\n\Rightarrow3x=63\n\n\text{Divide 3 on both sides, we get}\n\n\Rightarrow x=21$

Hence, the value of x = 21.

The answer is a, 21. 21x3 is 63. 63 + 1 = 64.
