M + 7 = m + 7
0 = 0
Infinite many solutions
This can be done by actually solving the operation 15/4:
15/4 = <u><em>3 3/4</em></u>
If you were to actually put in fifteen divided by four into a calculator, it would probably give you 3.75, which is equivalent to 3 3/4.
Hope this helps!
Answer:18
Step-by-step explanation:4(-3) = -12, and 40-12=18
The answer is D. because if there is 32 total, and 18 of them are girls, that means that there are 14 boys . with the question asking for girl/boy ratio it would have to be 18/14 in that order . if you divide 18 and 14 by two, they simple down to 9/7 . making the answer D.
Answer:
x = 7
Step-by-step explanation:
Let x = the number. Then
"Triple a number" means 3x
"is the same as" means =
"double the number increased by 5" means 2x + 7
∴ 3x = 2x + 7
Subtract 2x from each side
x = 7
The answer is x = 7.
Check:
3 × 7 = 2 × 7 + 7
21 = 14 + 7
21 = 21
OK.
