You plug in 2x + 4 into the y for the other equation (3x +y ) and solve for it
Answer:
K = 2/1
Step-by-step explanation:
Constant of proportionality can be found using any two given pair of values.
Constant of proportionality = y/x
Therefore, using (1, 2) , we have
Constant of proportionality = y/x = 2/1 = 2
Or it can be written as: k = ²/1 = 2
60 ft = 720 inches
15 ft = 180 inches
6 inches / 720 inches = 1/120
x inches / 180 inches = 1/120
1.5 = 1/120 of 180
The width of the model in inches is 1.5 inches.
Answer:
a) 1 hours and 25 minutes
b) 2 hours and 25 minutes
c) 1 hour
d) 30 minutes
Step-by-step explanation:
25/ 100 out of 5 = 1.25
45/100 out of 5 = 2.25
20/100 out of 5 = 1
10/100 of 5 = .5
Answer:
10
Step-by-step explanation:
( 1 / 20 ) x ( 1 / 8 ) x 1600
= ( 1 / 20 x 8 ) x 1600
= ( 1 / 160 ) x 1600
= 1600 / 160
