I believe the correct answer is 1.08
64-6= 58
58 squared= 7.6(or 7.61)
5+2= 7
7.6÷7= 1.08
Answer:
x=8
Step-by-step explanation:
If the value of x varies directly as the value of y we can say they are directly proportional. This implies that when y increases x will increase too, and when y decreases x will also decrease.
If x=16 when y=3/4 we can write their relation as:
x/y = 16/(3/4) = 16*(4/3) = 64/3
So, for every value of y, the ratio x/y must maintain equal to 64/3 because both values are proportional.
Now we can see what happens to x when y varies. If y=3/8:
x/(3/8) = 64/3
Multiply both sides by 3/8 to eliminate the 3/8 in the denominator.
x/(3/8) * (3/8) = (64/3) * (3/8)
See that we have a 3 multiplying and another dividing, we can eliminate them.
x = 64/8
x = 8
So, if y decreases to 3/8 x will decrease to 8. Notice that y is decreasing in a half as 3/8 is the half of 3/4, and x is also decreasing in a half from 16 to 8, what makes sense.

Step-by-step explanation:
Answer:
x = 3 and y = 7
Step-by-step explanation:
2x + y = 13
<u>+ x - y = -4</u> (adding both equations)
3x - 0y = 9
3x = 9
x = 9/3
x = 3
now substituting
x - y = -4
3 - y = -4
- y = -4 - 3
- y = -7
y = 7 (the negative sign on both sides get canceled)
Therefore,
x = 3 and y = 7
Happy to help :)
