Answer:
D
Step-by-step explanation:
If he travels 230 miles on 10gallons of fuel, then he will travel 23 miles on 1 gallon of fuel. So it is 230 gallons to one mile.
(5,25)(10,40)
slope = (40 - 25) / (10 - 5) = 15/5 = 3
y = mx + b
slope(m) = 3
(5,25)...x = 5 and y = 25
sub and find b, the y int
25 = 3(5) + b
25 = 15 + b
25 - 15 = b
10 = b
equation is : y = 3x + 10...sessions are $ 3 and the membership fee is $ 10
7.05÷ 3= 2.35 ( u divide the 3 tacos by price. to check answer multiply ur divided answer 2.35 x 3= 7.05)
Answer:
42%
Step-by-step explanation:
x is for the volume of the container
the amount filled in the first container=0.30x
the volume of the first container + 50% of the second=(x+x*50%)=1.5 x
the amount of acid in the second container= 1.5x * 50%=0.75x
total amount of acid in the third one =0.3x+0.75x=1.05x
total solution : x+1.5x=2.5x
percentage=1.05x/2.5x= 0.42 or 42%
