See the attached picture for 2 options for question 1 and 2 depending on how the fractions are written.

Question #3:

17 = -13 - 8x

Add 13 to each side:

30 = -8x

Divide both sides by -8:

X = 30 / -8

X = -3 3/4

What is the greatest common factor 15abc^2 and 25a^3bc

postnew [5]

To find the greatest common factor, first find the largest evenly divisible number that you can take out in both numbers, in this case 15 and 25. Then find the greatest or highest number of each variable that you can evenly take out or divide in both terms, this is for a, b and c.

So GCF of 15 and 25 would be 5
GCF of a = a^1 or a
GCF of b = b^1 or b
GCF of c = c^1 or c
Put everything together to find the GCF.
GCF = 5abc.

Please help does anyone know this

Answer:

Step-by-step explanation:

Hello There!

So if you didn't know an exterior angle of a triangle is equal to the two opposite interior angles of a triangle

So basically

∠XYZ=∠WXY+∠XWY

so to find ∠XWY we subtract the value of ∠WXY (45) from the value of the exterior angle (115)

115-45=70 so ∠XWY=70
