Svetradugi [14.3K]

Answer:

∠4 = 78°, assuming out measurements have been taken in degrees.

Step-by-step explanation:

If ∠2 = 8x + 10 and

∠4 = 42 + 6x

We will assume that x in both cases is represented by the same number, therefore, we will first need to solve for x. We will do so by equating both angle measurement expressions.

8x + 10 = 42 + 6x        Take away 6x from both sides

2x + 10 = 42                Take 10 away from both sides to combine like terms

2x = 32                        Divide both sides by 2 to isolate x

x = 16

Knowing x, we can solve for the measure of ∠4 by plugging in 16 for x

∠4 = 42 + 6x

∠4 = 42 + 6(6)

∠4 = 42 + 36

∠4 = 78°, assuming out measurements have been taken in degrees.

Fred has a bag of coin with only nickels and quarters. He got $20 by
Sedbober [7]

Answer:

75 quarters 25 nickels

Step-by-step explanation:

q=quarters n=nickels

q+n=100   n=100-q

0.25q +0.05(100-q)=20

From now I will multiply  by 100 to avoid decimals

25q + 5(100-q)=2000

20q=1500

q=75       n=25

75*0.25= 18.75

25*0.05=1.25

18.75+1.25=20
