So x and y
sum means add
difference means subtract
so we have
x+y=55 times (x-y)
use distributiver property which is
a(b-c)=ab-ac so
distribute 55(x-y)
55(x-y)=55x-55y
so we have
x+y=55x-55y
add 55y to boh sides
x+56y=55x
subtract x from both sides
56y=54x
divide both sides by 2
28y=27x
to find the ratio, switch the numbers around
ratio of y:x=27:28
therefor x is the greater number
ratio of larger to smaler is
28:27
linear pairs are supplementary so their sum equals 180°
(3x - 30) + (x + 76) = 180
4x + 46 = 180
4x = 134
x = 33.5
∠1: 3x - 30 = 3(33.5) - 30 = 70.5
∠2: x + 76 = (33.5) + 76 = 109.5
Answer: ∠1 = 70.5°, ∠2 = 109.5°
C = 2πr
C ≈ 2 * 22/7 * 7
C ≈ 44 cm
In short, Your Answer would be 44 cm
Hope this helps!
Answer:
67.5 mile per hour
Step-by-step explanation:
Kevin can travel LaTeX: 22\frac{1}{2}\:22 1 2miles in LaTeX: \frac{1}{3}\:1 3hour. What is his average speed in miles per hour? Group of answer choices
Speed = Distance /Time
Speed = 22 1/2 miles ÷ 1/3 hour
= 45/2 ÷ 1/3
= 45/2 × 3/1
= 67.5 mile per hour
