These are vertical angles
B. As all the sides are different lengths and angle f is bigger than 90 so it is obtuse
Hope this helps
Since the diameter of the cylinder is 10, its radius is half that, or 5, thus
Answer:
Cost of five blouses = $145
Step-by-step explanation:
Let
x = cost of blouse
y = cost of skirt
15x + 2y = 505 (1)
5x + 2y = 215 (2)
Subtract (2) from (1) to eliminate y
15x - 5x = 505 - 215
10x = 290
x = 290/10
x = 29
Substitute x = 29 into (2)
5x + 2y = 215 (2)
5(29) + 2y = 215
145 + 2y = 215
2y = 215 - 145
2y = 70
y = 70/2
y = 35
x = cost of blouse = $29
y = cost of skirt = $35
How much do 5 such blouses cost?
cost of a blouse = $29
Cost of five blouses = $29 × 5
= $145
Cost of five blouses = $145
2p-1q is the answer
5p+2q-3p-3q
isolate the variables:
5p-3p+2q-3q
simplify:
2p-1q
that is the answer!
hope I helped! :)
