Answer:
1. 2x=5
Divide both by 2, x=2.5
2. y+1.8=14.7
Subtract 1.8 from both sides to isolate the variable, x=12.9
3. 6=1/2z
Multiply each side by 2 to isolate the variable, 12=z
4. 3 1/4 = 1/2+w
Isolate the variable by subtracting 1/2 to both sides, 2 3/4 = w
5. 2.5t=10
Divide each side by 2.5 to isolate the variable, t=4

Answer:
4.5 cm
Step-by-step explanation:
Circunference = 2π*radius = 2*3.14*radius = 6.28*radius = 28.26
so radius = 28.26/6.28 = 4.5 cm
Answer:
<h2>rise = 6</h2>
Step-by-step explanation:
The GCF is the greatest common factor.
Find the factors for 45, 90, and 75;
45: 1, 3, 5, 9, 15, 45
90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
75: 1, 3, 5, 15, 25, <span>75
Now find the biggest factor they have in all, which is 15.
