Answer:
ST=26
Step-by-step explanation:
RS+ST=RT
17+x+16=4x+3
x+33=4x+3
33-3=4x=x
3x=30
x=30/3
x=10
ST=x+16
ST=10+16
ST=26
Hey! :)
you went on the roller coaster 7 times and the ferris wheel 5 times
Hope this helps! :)
Answer:
-2
Step-by-step explanation:
1. Distribute: -3x + 6x + 3 = x-1
2. Combine like terms: 3x + 3 = x-1
3. Subtract 3 on both sides: 3x = x-4
4. Subtract x on both sides: 2x = -4
5. Divide each side by 2: x = -2
6. Check by plugging in -2 to the equation:
Okay. The equation for a sphere's surface area is A = 4 * pi * r^2. Let's plug 5 in for r.

I got 314 cm^2 is the surface area, but it always helps to double check work! Hope this helps!
