The value of x is 4
18 = 10 + 2x
8 = 2x
4 = x
Answer: The weight of the box is 0.2 pounds and the weight of the chocolates before any chocolates were taken out is 2 pounds
Step-by-step explanation:
Let x represent the weight of the box only.
The weight of the box of chocolates is 2.2 pounds. It means that the weight of the chocolate only is
(2.2 - x) pounds
After taking out 75% of the chocolates, the remaining chocolates and the box weigh 0.7 pounds. It means that
2.2 - 0.75(2.2 - x) = 0.7
2.2 - 1.65 + 0.75x = 0.7
0.75x = 0.7 + 1.65 - 2.2
0.75x = 0.15
x = 0.15/0.75
x = 0.2 pounds
The weight of the chocolates before any chocolates were taken out is
2.2 - x = 2.2 - 0.2 = 2 pounds
Answer:
x=50
Step-by-step explanation:
5*10 = 50
i think this is the answer
Answer:
y = 1/4x +7
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 1/4 x +b
Substitute the point into the equation
8 = 1/4(4) +b
8 = 1 +b
Subtract 1 from each side
8-1 =b
7 =b
y = 1/4x +7
