Enter those coordinates into the table.
3 * 0.28 + 0.38y = the total cost
Step-by-step explanation:
Answer:
a) x=3
b) x=4.5
Step-by-step explanation:
2(5x – 3) = 24
10x-6=24
10x=30
x=3
5(2x + 1) = 50
10x+5=50
10x=45
x=4.5
Answer:
∠ QPR = 64.5°
Step-by-step explanation:
The chord- chord angle QPR is half the sum of the arcs intercepted by the angle and its vertical angle, then
∠ QPR =
(QR + ST ) =
(98 + 31)° = 0.5 × 129° = 64.5°
