yan [13]

Answer:

We first must solve for x

$9x-x+5x=260\\13x=260\\x=30$

When we have x, we put it in to the second equation

$Bx=200\\\\B=\frac{200}{x} \\\\B=\frac{200}{30}\\\\B=\frac{20}{3}$

Solve the following inequality for s. Write your answer in simplest form.

Doss [256]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

$\qquad \sf \dashrightarrow \: - 10 + 5(78 + 8) < - 4s + 3 - 8$

$\qquad \sf \dashrightarrow \: - 10 + 5(86) < - 4s - 5$

$\qquad \sf \dashrightarrow \: - 10 +430 < - 4s - 5$

$\qquad \sf \dashrightarrow \: 420 + 5 < - 4s$

$\qquad \sf \dashrightarrow \: 42 5 < - 4s$

$\qquad \sf \dashrightarrow \: 42 5 \div 4 < - s$

$\qquad \sf \dashrightarrow \: 106.25 < - s$

Inequalities change when it is multiplied by -ve number

$\qquad \sf \dashrightarrow \: - 106.25 > s$
