Answer: 148


A triangle = 180

So all three sides have to add up to 180.

If one side is 12 And the other is 20 you add that makes 32.

12 + 20 = 32

Now we need to find the length of the other side. 32 is two of the sides and 180 is the whole. So something + 32 = 180

32 + x = 180

To find x you subtract 32 from 180

180 - 32 = 148

Hope this helps

Marita orders 12 yards of material to make banners. If she needs 1 foot of fabric for each banner, how many banners can she make
Alik [6]
Well 3 feet=1 yard
so the conversion factor is 3ft/1yd

so 12 yards converted to feet is
12yd times 3ft/1yd
the yd will cancel and you will be left with 36 feet

each banner is 1 foot so 36/1=36
she can make 36 banners

What is the slope of the line whose equation is 2x−4y=10 ?
Olenka [21]

solve for y

2x−4y=10  

-2x       -2x      subtract -2x from both sides

-4y = -2x +10

-4            -4    Divide both sides by -4 (coefficient on y)

y = -2/-4x  + 10/-4

y = 1/2x - 5/2


the slope is the number on the x (coefficient)

and its 1/2
