Question

4 fill in the blank 0 points
-(7 - 2x) + 7 = -7
n = type your answer...
this answer is a fraction (use /) or a decimal
5 fill in the blank 0 points
200 = 16(6t - 3)
n = type your answer...
this answer is a fraction (use /) or a decimal

Explanation:

Step1: Expand the left-hand side

$-(7-2x)+7 = -7 + 2x + 7 = 2x$
Equation becomes: $2x = -7$

Step2: Solve for $x$

$x = \frac{-7}{2} = -3.5$

Step3: Divide both sides by 16

$\frac{200}{16} = 6t - 3$
Simplify: $12.5 = 6t - 3$

Step4: Isolate the term with $t$

$6t = 12.5 + 3 = 15.5$

Step5: Solve for $t$

$t = \frac{15.5}{6} = \frac{31}{12} \approx 2.583$

Answer:

For question 4: $\boldsymbol{-\frac{7}{2}}$ or $\boldsymbol{-3.5}$
For question 5: $\boldsymbol{\frac{31}{12}}$ or $\boldsymbol{\approx 2.583}$
