4h - 6= 22-8s + 1= 33
-4w - 4= 8
5 +1/7b = -2
i need help on these problems!

Answers

Answer 1
Answer: 4h−6=22
1. Add 6 to both sides.
4h−6+6=22+6
4h=28
2.Divide both sides by 4.
4h/4=28/4
h=7

−8s+1=33
1: Subtract 1 from both sides.
−8s+1−1=33−1
−8s=32
2: Divide both sides by -8.
−8s/−8=32/−8
s=-4


−4w−4=8
Step 1: Add 4 to both sides.
−4w−4+4=8+4
−4w=12
2: Divide both sides by -4.
−4w/−4=12/−4
w=−3


Step 1: Simplify both sides of the equation.
1/7b+5=−2
 2: Subtract 5 from both sides.
1/7b+5−5=−2−5
17b=−7
3: Multiply both sides by 7.
7*(1/7b)=(7)*(−7)
b=−49

What is the GCF of 24,44,52

Answers

The greatest common factor (GCF) of 24, 44, and 52 is: 4

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Factors of 44: 1, 2, 4, 11, 22
Factors of 52: 1, 2, 4, 13

The common factors between them are 1, 2, and 4, but 4 is the greatest, making it the GCF.

Answer:

104.1

Step-by-step explanation:

Use SOH CAH TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

In this case, the hypotenuse is x, and the side opposite of the 22° angle is 39.  Since we have opposite and hypotenuse, we need to use sine.

sin 22° = 39 / x

x sin 22° = 39

x = 39 / sin 22°

x ≈ 104.1
