Step-by-step explanation:
Answer:
C. 11
Step-by-step explanation:
Substituting, we have ...
8{80, 19, 11} ?= 88
{640, 152, 88} ?= 88
The value from the set that makes the equation true is x = 11.
_____
<em>Alternate methods of solution (other than substitution)</em>
It can be easier to make use of your knowledge of factoring:
8x = 8·11
x = 11
Or to make use of your knowledge of numbers (place value):
8·10 = 80
so x will not be very different from 10.
I think the best answer would be (A) (2.1+5.9+3.7) but the only difference is that one is negative an the other is positive
Y = 172.972972972...
You need to isolate the variable, y. To do this, you need to divide both sides of the equation by 0.74. This gives you your final answer.
