3(13-2a)=-3+a
39-6a=-3+a
42=7a
a=6
The first step is seeing how many times 5 can go in 48. 5 can go in 48 9 times. Then you multiply 310 by 9 which equals 2790. Then you divide 310 by 5 which equals 62. Then you add 62 , three times, to 2790.
The final answer is 2979 quarts.
Answer:
x = - 8/23
y = 40/23
Step-by-step explanation:
-5x- y = 0
and
-8x+3y = 8
The first step to solve this would be to get what one of the two variables equal. The easiest in this case is y from the first equation.
-5x-y = 0
-y = 5x
y = - 5x
Now you can take this y value and plug it into the section equation.
-8x + 3(-5x) = 8
-8x - 15x = 8
-23x = 8
x = - (8/23)
Once you get the x value you can plug it back into equation one to get y's value
-5*-(8/23) - y = 0
40/23 - y = 0
y = 40/23
Ok so... what wait weres the pic??
Answer:
It describes multiplication
Step-by-step explanation:
As you can see its 5x-5 (the x is say "by" or "of), So when you look at it you can clearly see it's multiplication.
