adoni [48]

Answer:

$S=45m+15$

Step-by-step explanation:

we have

E------>the number of sit-ups

m----> the time in minutes

S----> the number of sit-ups after drinking the sports drink

$E=15m+5$ ----> equation A

$S=3E$ ----> equation B

substitute the equation A in the equation B

$S=3(15m+5)$

$S=45m+15$

Solve the system by substitution. y = -9x y = 2x + 33

Gwar [14]

Answer:

$y = - 9x \\ theny = 2x + 33 \\ - 9x = 2x + 33 \\ - 9x - 2x = 33 \\ - 11x = 33 \\ x = \frac{ - 33}{11} = - 3 \\ x = - 3 \\then\\ y=-9×-3=21\\ thank \: you$

I need answer please

zhenek [66]

Answer:

We know that lines l and m are parallel. The alternate interior angles rule states that the alternate interior angles formed by parallel lines are equal. So let's equate them.

2x + 22 = 4x

putting variables on one side,

22 = 4x - 2x

Thus 2x = 22

x becomes 22÷2

Therefore, x = 11.
