Answer:
what do u mean, never mind answer is square units
Answer d: 3 pails
The area of the ceiling:
A = 142 = 196 f2
We need plaster to cover 196 $2
196: 90 = 2.17778
Answer: We have to buy 3 pails of plaster
360 - 90 = 270
Plug in the two expressions
270 = (7x + 6) + (6x - 7) -> expand
270 = 42x^2 - 1 -> bring the one to the other side and add
271 = 42x^2 -> divide by 42
6.4 = x^2 -> find the square root
2.5 = x
Then solve both equations with x = 2.5 :^)
Hope this helped!!
Answer: 26
Step-by-step explanation: he will have 4 red fish 15 black fish then you add them together 4+7=11 11+15=26
25 to 45 can also be written as 25/45
Both numbers are divisible (can be divided by) 5
25 divided by 5 = 5
45 divided by 5 = 9
So 25/45 = 5/9
They are equivalent fractions because they’ve been divided by the same, shared number
