Answer:

y=-3

Step-by-step explanation:

Given Equation:  

                            9x +7y=-12\\             y=?       at    x= 1

Putting the given value of 'x' in the equation:

                            9(1) +7y=-12\\\\9+7y=-12\\\\7y=-12-9\\\\7y=-21\\\\y=-\frac{21}{7} \\y=-3

At x=1, the value of y is y=-3

loris [4]

Answer:

14 1/2

Step-by-step explanation:

Rewriting our equation with parts separated

=7 + 7/8 + 6 + 5/8

Solving the whole number parts

7 + 6=13

Solving the fraction parts

7/8 + 5/8= 12/8

Reducing the fraction part, 12/8,

12/8=3/2

Simplifying the fraction part, 3/2,

3/2=1 1/2

Combining the whole and fraction parts

13 + 1 + 12=14 1/2

Simora [160]

Answer:

10%

Step-by-step explanation:

In this question, we are asked to calculate the percentage error in a measurement.

This can be obtained by first getting the error involved. That is calculated by Subtracting the value calculated from the actual value. That is 9.5 - 8.9 = 0.6

The percentage error is thus 0.6/9.5 * 100 = 6%

The value is actually 10% to the nearest tenth of a percent

Alexxandr [17]

Answer: x = 1

Step-by-step explanation:

Step 1: Cross-multiply.

x/8 = 8/64

x*(64)=(8)*(8)

64x=64

Step 2: Divide both sides by 64.

64x/64 = 64/64

\frac{64x}{64} =\frac{64}{64} \\

Therefor, the answer is x = 1
