Find MP.<br><br> MN=17<br> NP=3y<br> MP=5y+9
8_murik_8 [283]

Answer:

MP = 29

Step-by-step explanation:

Given:

MN = 17

NP = 3y

MP = 5y + 9

MN + NP = MP (segment addition postulate)

17 + 3y = 5y + 9 (substitution)

3y = 5y + 9 - 17 (subtracting 17 from each side)

3y = 5y + 8

3y - 5y = 5y - 8 - 5y (Subtracting 5y from both sides)

-2y = 5y - 8 - 5y

-2y = - 8

y = 4 (dividing both sides by -2)

MP = 5y + 9

Plug in the value of y

MP = 5(4) + 9 = 20 + 9

MP = 29

2x is the $2 per card with x representing the number of cards (which we don't know)

And of course 10 is the cover charge.

Find the slope of the line 7x+4y=10
Fittoniya [83]

Answer:

The slope is -7/4

Step-by-step explanation:

∵ 7x + 4y = 10

∵ y = mx + c ⇒ where m is the slope of the line

∴ Re-arrange the equation

∴ 4y = 10 - 7x ⇒ ÷4

∴ y = 10/4 - (7/4) x

∴ y = 5/2 - (7/4) x

∴ The slope is -7/4

The length of a rectangle is 7/6 its width, w. Which expression represents the perimeter of the rectangle?
Hitman42 [59]
If the length is 7/6 the width w then the perimeter is w + (7/6)w + w + (7/6w)
= 2((7/6)w + w) = 2w + (14/6)w = (26/6)w = (13/3)w.
So the answer is the last one.
