Answer:
-1/4 (2x - 5y)
Step-by-step explanation:
For us to factor -1/4 out of -1/2x -5/4y
We will have to multiply the values in bracket by the reciprocal of -1/4 i.e -4 as shown
-1/2x - 5/4 y
= -1/4 (-4(-1/2x) - (-4)(-5/4y))
= -1/4 (4/2 x - 20/4 y)
= -1/4 (2x - 5y)
Hence the factored expression is -1/4 (2x - 5y)

Answer:
Area = 1250 square feet
Step-by-step explanation:
The formula for area of the bottom of the pool is given by:
Area = length× breadth
= 50 × 25
= 1250 square feet
Cost/gallon
67.50/23 = x/1
23x = 67.50
23x/23 = 67.50/23
x = 2.93
they spent approximately $2.93 per gallon on gas
Answer:
m= 1.1
Step-by-step explanation:
Given the question as 7:( 4/11 m)=56:3.2 this can be written as;
7: 4/11 m = 56 /3.2
7/4/11m = 560/32 ------------------perform cross multiplication
77*32=560*4/11m
224=2240/11 m
224=203.636 m--------------divide both sides by 203.636 to get m
224/203.636 = 203.636m/203.636
1.1 =m
Testing the value of m in the question
7: (4/11 *1.1) = 56:3.2
7:0.4 = 56 :3.2
70/4 = 560/32
17.5 =17.5
