Answer:
1. y=2x-2
Because the slope is 2 over 1. and the y-intercept is at -2.
2. I think is y=1/5x-2
Density = Mass/Volume
Mass = 152.7 gVolume = 9.5 mL
Since the mass gram correspond to the volume mL, then we can apply the formula:
Density = 152.7/9.5 = 16.074 g/mL (Or kg/L)
70a + 55b = 905
a + b = 14
55a + 55b = 770
(70a-55a) + (55b-55b) = 905 - 770
15a = 135
a = 9
a + b = 14
9 + b = 14
b = 5
Answer:
14.95
Step-by-step explanation:
every 1 pound is 2.99 so you would do 2.99 * 5
