70 divided by 7 equals 10.
Tamara practiced the piano for 10 minutes on Monday. <span />
So x + y = 45, and 4x + 5y = 195. Get y by itself. Subtract x from both sides in the first equation to get y = 45 -x, and subtract 4x from the second equation to get 5y = 195 - 4x. Divide by 5 to both sides to get y = 39 - 4/5x. 39 - 4/5x = 45 - x. Add x to both sides to get 39 - 1/5x = 45. Subtract 39 from both sides to get -1/5x = 6. Divide by -1/5 to get x = -30, or 30. In the first equation, do 30 + y = 45. Subtract 30 from both sides to get y = 15. Check. 4(30) + 15(5) = 195, or 120 + 75 = 195.
The slope is 12x, remember the slope is the number value before the variable!
The answer is -s^1000+s^22+s^220+1.
Answer:
25 percent
Step-by-step explanation:
to get percent you need a fraction of something over a hundred. To get there, you simplify this to 1/4, then go to 25/100, so 25%
