Answer:
In order to properly answer this, we need to know the measurement of the pool in meters
Step-by-step explanation:
Distribute The 4 In Problem Number 2. (4*2.5X)+(4*1.25) = 77
Simplify. 10X+5 = 77. Now, Subtract 5 From Both Sides.
10X = 77-5
10X = 72.
Now, Divide.
X = 72/10.
X = 7.2.
For 13, We Have This:
3/5p+2/3 = 8.
Now, Subtract 2/3.
3/5p = 7 1/3
Now, Divide.
7 1/3 Needs To Be Converted To An Improper Fraction.
It Becomes 22/3.
22 5 110
--- * --- = ----
3 3 9
Now, Make Into A Proper Fraction.
It Becomes 12 And 2/9.
The 2 equations have no solution. If both are true, then
-3x + 3y = 4
-x + y = 4/3
Thus, 3 = 4/3, which is obviously wrong. Pls mark me as brainliest!
2)
32/28=w/7
you cross multiply one denominator by the other numerator so
32(7)=(28)(w)
simplify
224=28w
divide 28 from both sides to get w alone
8=w
4)
36/21=24/s
cross multiply just like in the last problem
(36)(s)=(21)(24)
simplify
36s=504
divide 36 to get s alone and essentially solve for s
S=14
