Lynn mixes 39 pounds of water with 48 pounds of brick dust, so the mixture has a total weight of 39 + 48 = 87 pounds.
13 pounds are spilled during mixing, so she's left with 87 - 13 = 74 pounds to turn into bricks.
7 pounds are needed for 1 brick, so she can make 10 bricks because 7 • 10 = 70 and 7 • 11 = 77, and 70 < 74 < 77.
If she uses the mixture to make 10 bricks, she uses up 70 pounds of it, which leaves 4 pounds to be washed out.
Answer:
186 degrees fahrenheit or 85.56 degrees celcius
Step-by-step explanation:
136-(-50)=186
I think you use
xamount(1-.8)
.8 being 80% as a decimal.
1 being 100%
so .2 or 20% remaining multiplied by whatever amount.
Answer:
13.75 or 13 3/4 as a fraction
Step-by-step explanation:
depends how you wanna do it, you can just change the fraction into a decimal since it's an easy one. 2 3/4 is 2 and 3/4, 3/4 is 75% or 0.75, so 2 3/4 = 2.75, multiply by 5 (or by 10 and then divide by 2 if that's easier) = 13.75 or 13 3/4
Answer:
The answer is A, (1,2).
Step-by-step explanation:
Hope this helps!
8x-4(x+1) = 0
x =1
y = 1 + 1
y = 2
(x,y) = (1,2)
2 = 1 + 1
8 x 1 - 4 x 2 = 0
Simplify
2 = 2
0 = 0
Solution = (1 , 2)
