Substitute the given information into the formula and do the arithmetic.
5(86 -32)/9 = 5(54/9) = 5(6) = 30
The temperature was 30 °C.
Answer:
(9,3)
Step-by-step explanation:
4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
Divide both sides by 2
x = 9
Substitute x = 9 into x + 2y = 15
9 + 2y = 15
Subtract 9 from both sides
2y = 6
Divide both sides by 2
y = 3
Solution
(9, 3)
Answer:
diagrama c
Step-by-step explanation:
I'm not quite sure how you got your answer, but the answer to c is 57 tiles.
First we can find the area of a singular tile by multiplying 12 and 12 together to get 144 in².
Then we find the area of the kitchen floor by splitting it into two rectangles, finding those areas, and adding them. This gives us (108 × 60) + (48 × 36) = 6,480 + 1,728 = 8,208 in².
Then to find how many tiles fit, we need to divide the total area, 8,208 in², by the area of a singular tile, 144 in², which results in 57 tiles.
I hope this helps!
