38 cm sum of all sides is equal to the perimeter
Answer:
x = 12
Step-by-step explanation:
We know that the total angle measure of a triangle is 180 degrees, so the sum of all the angles should be 180 degrees.
Therefore, we can add all the angles, set them equal to 180 and solve for x
2x+5 + 6x-5 + 7x = 180
We can combine all the x terms and all the numerical terms on the left side of the equation to get:
(2x+6x+7x) + (5-5) = 180
15x = 180
Then we can divide both sides by 15 to isiolate x
15x = 180
x = 180/15 = 12
Answer:
r + ¾ = ⁷/₈
r = ⁷/₈ - ¾
⁷/₈ - ⁶₈ = ¹/₈
r = ¹/₈
Step-by-step explanation:
but my original answer was 4/4
T=5w
T= total cost
W= weeks
It can't be W= because the question is asking for total cost in dollars, so two options are cancelled out.
Can't be t=5+w because it's 5 per week and if, let's say calculating dollars for 2 weeks, the answer would be t=5+2=7 and that wouldn't be right
