Answer: Tyler mowed the lawn 4 times
Step-by-step explanation:
Let x = number of times that he does laundry
Let y = number of times that he mows the lawn
In one month, he does the laundry 6 more times than he mows the lawn. This means
x = 6 +y
Tyler's parents pay him $ 0.75 to do the laundry and $ 1.75 to mow the lawn. If his parents pay him $ 14.50 that month, it means that
0.75x + 1.75y = 14.5 - - - - - - -1
Substituting x = 6+y into equation 1, it becomes
0.75(6 + y) + 1.75y = 14.5
4.5 + 0.75y + 1.75y = 14.5
0.75y + 1.75y = 14.5 - 4.5
2.5y = 10
y = 10/2.5 = 4
x = 6 + y = 6 + 4
x = 10
Step-by-step explanation:
EQUATION: Volume=length x width x height.
V=l×w×h
1620cm^3=9cm×9cm×xcm
1620cm^3=81cm^2 ×xcm
xcm= 1620cm^3/81cm^2
xcm= 20cm

Answer:
C. 9
Step-by-step explanation:
He is going to have 12 people including himself, and each is going to have 750 mL
12*750
9000 mL
There are 1000 mL in each liter, so divide 9000 by 1000
9000/1000=9
So he needs to buy 9, 1 liter containers of fruit punch
Hope this helps :)
Answer:
The function increasing ⇒ 3 ≤ x ≤ 6 answer C
Step-by-step explanation:
∵ The vertex of the parabola is (3 , -6)
∴ The minimum value = -6 at x = 3
∵ The left part of the parabola is decreasing because the value of y decreased from 3 to -6 when 0 ≤ x ≤ 3
∵ The right part of the parabola is increasing because the value of y increased from -6 to 3 when 3 ≤ x ≤ 6
∴ The function is increasing at interval 3 ≤ x ≤ 6
