For 11, set them equal to each other, since they both equal y.
y=2x+5; y=3x-1
2x+5=3x-1
x=6
and then substitute that x-value to find y.
y=3(6)-1
y=18-1
y=17
for 14 you can substitute the bottom y-value (x+7) into the top equation.
2x=y-10; x+7=y
2x=(x+7)-10
x=-3
and then substitute that x-value to find y.
-3+7=y
y=4
Answer:
1: 23.85
2: 83%
3: 44
Step-by-step explanation:
1 - do 53x0.45 (23.85)
2 - Divide 20 by 24, which you get 0.833333333 and move the decimal 2x to the right. You get 83.3333333, but round. So 83%
3 - do 80x0.55 (44)

Answer = 5,100
1 second = 2 megabytes
2 seconds = 4 megabytes
Step-by-step explanation:
Given,
Time taken to download 5 megabytes = 
seconds
Multiplying both sides by 
to find unit rate
1 second = 2 megabytes
2 seconds = 2*2 megabytes
2 seconds = 4 megabytes

Answer: Swing twice as fast
Explanation: If superman wants to get a lot of kinetic energy he should swing fast. Kinetic energy is the energy of motion/movement so that means the more you do something fast the more KE you will get and if you do something twice as fast then you will gain more kinetic energy.
