Is 3(5x - 4) = 15x - 12 a one solution , no solution or infinite solutions
1 answer:
Answer:
Infinite Solutions
Step-by-step explanation:
3(5x - 4) needs to be simplified
So we multiply 5x by 3
So 3 x 5x = 15x
Then we multiply -4 by 3
3 x -4 = - 12
Put those together we get 15x - 12
The same equation as the one on the right side
So since 15x - 12 = 15x - 12, the x variable can be any number

mean = sum/n
mean = (5 + 7 + 7 + 9 + 12 + 16 + 21)/7
mean = 77/7
mean = 11
Answer:
c 2 1/2
Step-by-step explanation:
Answer:
7(6m - 4) = -364
multiply 7 for both variables in the parenthesis
42m - 28 = -364
move 28 to other side
42m= -336
divide 42 on both sides
m= -8
The equation should look like : [H+] = (1-a)(x) + (a)(y) Where: 5.8 = -log [H+] 5.0 = -log x 6.9 = -log y (1-a) = proportion of x <span>a = proportion of y so calculating a will give you the result of how many ounces are required</span>
