A linear pair is a pair of angles that form a line. And since they form a line, when added, they equal 180.
x = one angle....y = the other one
x + y = 180
x = y + 26
time to sub
y + 26 + y = 180
2y + 26 = 180
2y = 180 - 26
2y = 154
y = 154/2
y = 77 <=== this is one angle
x = y + 26
x = 77 + 26
x = 103 <=== and the other one
Answer: 70%
Step-by-step explanation: 21 out of 30 students have 5 or more vowels in their name and 21/30 as a percentage is 70% so that is your answer
25% of 120
25/100×120
1/4×120
120/4
30
25% of 120 is 30
Answer:
I'll explain below, just follow the directions. I can't directly draw it.
Step-by-step explanation:
find the length and the width of a rectangle whose perimeter is 18 ft
2L + 2W = 18
simplify, divide by 2
L + W = 9
L = (9-W)
:
whose area is 20 square feet
L*W = 20
Replace L with (9-W)
W(9-W) = 20
-W^2 + 9W - 20 = 0
Multiply by -1, easier to factor
W^2 - 9W + 20
Factors to
(W-4)(W-5) = 0
Two solutions
W = 4 ft is width, then 5 ft is the Length
and
W = 5 ft is the width, then 4 ft
Answer:
It is -1 with 1/2.
