Answer:

-13t-1

Step-by-step explanation:

Given two equations

t2 - 8t - 7 ----------------- (1)

t2 + 5t - 6 ----------------- (2)

Now subtracting (2) from (1), we get

( t2 - 8t - 7 ) - ( t2 + 5t - 6 )

t2 - 8t - 7 - t2 - 5t + 6

-13t-1

Therefore, answer is -13t-1

(t2 - 8t - 7) - (t2 + 5t - 6)
=t2 - t2 - 8t - 5t - 7 + 6
= -13t-1

Answer: A; 6.3%

Step-by-step explanation:

Problem 1

For the first problem, we first want to find y so that we can plug it into the expression.

We can use elimination method for the system of equations to solve.

3x+3y=21

3x-y=5

We subtract both equations to eliminate x.

4y=16 [divide both sides by 4]

y=4

Now that we know y, we can plug it into the expression.

$\frac{4}{2} -3$ [divide]

$2-3$ [subtract]

$-1$

We know that the answer is A.

Problem 2

For the second problem, we need to know how to calculate percent error. The formula for precent error is $\frac{|measured-exact|}{exact} *100%$ . We know that the exact value is 80 because the buyer was supposed to given 80. 75 is the measured value because that was what the buyer was given.
