6 0

Step-by-step explanation:

Substitute the y in the 1st equation with the 2nd equation.

7x + 10(2x + 9) = 36

7x + 20x + 90 = 36

27x + 90 = 36

3x + 10 = 4

3x = -6

x = -2

So now we can find y.

y = 2x + 9 = 2(-2) + 9 = (-4) + 9 = 5.

So x = -2, y = 5.

Find the value of each variable so that PQRS is a parallelogram. Explain what allows you to do this.
Nataly [62]

Answer:

x = 5

y = 16

Step-by-step explanation:

Given

See attachment for parallelogram

Required

Find variables x and y

Solving for x, we have:

5x = 25 ---- Opposite sides of a parallelogram

\frac{5x}{5} = \frac{25}{5} ------ Divide both sides by 5

x = 5

Solving for y, we have:

3y - 1 = 47 ---- Opposite sides of a parallelogram

3y = 1 + 47 ------ Collect like terms

3y = 48

\frac{3y}{3} = \frac{48}{3} ---- Divide both sides by 3

y = 16

Which equation could be used to find the number of minutes, m, in h hours?
Afina-wow [57]
The equation would be m=60h.

there are 60 min. in an hour and so you can use this equation to convert from hours to min.

If you want to ever convert from min to hours, you would use the equation h=m/60
