One week a computer store sold total of 36 computers and external drives. The revenue from these sales were $23490. If computers
sold for $1180 per unit and hard drives were $125 per unit, how many of each did the store sell? How many computers were sold?
1 answer:
Answer:
X = 18
Y = 18
Step-by-step explanation:
first make two equation like
x + y = 36
1180x + 125y = 23490
from equation one we have
y = 36- x
put in second equation
1180x + 125 (36-x) = 23490
1180x + 4500-125x = 23490
1055x = 23490-4500
x = 18990/1055
x = 18
put this x value in equation 1 to find y value
18+ y = 36
y = 36-18
y = 18

Answer:
(x+7) times (x+3)
Step-by-step explanation:
Because a area of a rectangle is lw and you combine x and 3 to make x+3 and 7 and x to make x+7 and you multiply them together.
Answer:
Step-by-step explanation:
(1, 5.5) ; (2, 9)
Slope = 
= 7/2
m = 7/2 ; (2 , 9)
y - y1 =m(x -x1)
Multiply the equation by 2
