Answer:
x = price of balcony tickets = $7
y = price of orchestra tickets = $21
Step-by-step explanation:
Let
x = price of balcony tickets
y = price of orchestra tickets
y = 3x (1)
148y + 76x = 3,640 (2)
Substitute y = 3x into (2)
148y + 76x = 3,640 (2)
148(3x) + 76x = 3,640
444x + 76x = 3,640
520x = 3,640
x = 3,640/520
x = 7
Substitute x = 7 into (1)
y = 3x (1)
y = 3(7)
y = 21
x = price of balcony tickets = $7
y = price of orchestra tickets = $21
Answer:
(1. 5
(2. 180
(3. 900
(4. 5180=900
Step-by-step explanation:
Perimeter P=2L+2W
P=24
L=w+4
P=2(w+4)+2w
24=2w+8+2w
24=8+4w
16=4w
w=4
L=8
The expected diameter is 70 cm.
It is acceptable for the diameter to be within 0.02 cm of the expected value.
Therefore the acceptable values for the diameter, d, are
The minimum acceptable value of d is obtained from
d + 0.02 = 70
d = 69.98 cm
The maximum acceptable value of d is obtained from
d - 0.02 = 70
d = 70.02 cm
Answer:
Minimum acceptable diameter = 69.98 cm
Maximum acceptable diameter = 70.02 cm
Answer: y = 3 or y=7
Step-by-step explanation:
what 2 factors of 21 can equal 10 when added together (1*21- no 3*7- yes)
Factor
y-3=0
y=3
or y-7=0
y=7
