Answer:
5 x - 2x + 7 - x = 2x + 7
Step-by-step explanation:
simplify
(5x - 2x - x) = 2x
2x + 7 = 2x + 7
Answer:
instead of just pointing out the highest speed or one speed, list all the different speeds or increasing/decreasing and the different intervals
ie for minutes 2 to 3, her speed was 30 mph . . . from minutes 6 to 8, her speed was decreasing at a constant rate of -2 mph/min
supplementary angles measure 180°
Answer:
x = 30
Step-by-step explanation:
The perimeter is the sum of all of the sides of a shape. Therefore, because the sum is equivalent to 104 inches and we are given the lengths of all three sides, we can add the three sides together and set them equal to 104 in order to solve for x.
(x + 3) + (x + 4) + (x + 7) = 104 Drop the parentheses.
x + 3 + x + 4 + x + 7 = 104 Combine like terms (variables first!).
3x + 3 + 4 + 7 = 104 Now, combine constant terms.
3x + 14 = 104 Subtract 14 from both sides.
3x = 90 Divide by 3 on both sides of the equation.
x = 30
I'm not 100% sure but i think it is 35x+13
