Answer:
Step-by-step explanation:
Let n represent the number of friends who went to the movies with you.
Then ($12/ticket)n + $15 = $75. Solving for n, we get:
$75 - $15 $60
---------------- = ----------------- = 5 so a total of 5 friends went with you.
($12/ticket) ($12/ticket)
I don’t see a dot plot so i can’t answer this...sorry :(
42 + 8x + 13 = 7
8x + 55 = 7
8x = 7 - 55 subtract both sides by 55
8x = -48
x = -48/8 divide both sides by 8
x = - 6
hope this helped, God bless!
Answer:
7+2(a-3)=-9
a= -5
Step-by-step explanation:
7+2(a-3)=-9
<u>Distribute</u><u> </u> 2 through the parentheses
<u>Example</u><u>:</u> 7+2a-6=-9
Next: 7+2a-6=-9
Subtract the numbers
1+2a=-9
Move constant to the right hand side and change its sighn 2a=-9-1
<u>2a</u><u>=</u><u>-9-1</u>
<u>Calculate</u><u> </u><u>the</u><u> </u><u>difference</u><u> </u>
2a=-10
<u>Divide</u><u> </u><u>both</u><u> </u><u>sides</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>equation</u><u> </u><u>by</u><u> </u><u>2</u>
<u>Answer</u><u>:</u><u> </u>a=- -5
