Simplifying
8.7 = 3.5m + -2.5(5.4 + -6m)
8.7 = 3.5m + (5.4 * -2.5 + -6m * -2.5)
8.7 = 3.5m + (-13.5 + 15m)
Reorder the terms:
8.7 = -13.5 + 3.5m + 15m
Combine like terms: 3.5m + 15m = 18.5m
8.7 = -13.5 + 18.5m
Solving
8.7 = -13.5 + 18.5m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-18.5m' to each side of the equation.
8.7 + -18.5m = -13.5 + 18.5m + -18.5m
Combine like terms: 18.5m + -18.5m = 0.0
8.7 + -18.5m = -13.5 + 0.0
8.7 + -18.5m = -13.5
Add '-8.7' to each side of the equation.
8.7 + -8.7 + -18.5m = -13.5 + -8.7
Combine like terms: 8.7 + -8.7 = 0.0
0.0 + -18.5m = -13.5 + -8.7
-18.5m = -13.5 + -8.7
Combine like terms: -13.5 + -8.7 = -22.2
-18.5m = -22.2
Divide each side by '-18.5'.
m = 1.2
Simplifying
m = 1.2
You would divide 27/6.75.
You'd get 4, so 4 people went.
To check you would do 4x6.75 and your get the total of 27$
Answer:
35 dogs
Step-by-step explanation:
x ---> the number of dogs
y ---> the number of cats
The last week of January we have 20 cats and the ratio is the same
so
\frac{x}{y}=\frac{49}{28} ----> equation A
y=20 ---> equation B
substitute equation B in equation A
\frac{x}{20}=\frac{49}{28}
solve for x
x=\frac{49}{28}(20)=35 dogs
First if each stack has 10 cds and there is 5 stacks you do 10 X 5= 50. then you add two more stacks of 10 ( 2 stacks of 10=20) and add 20 to 50 which is 70
Answer: 32%
Step-by-step explanation:
From the question, we are informed that out of 150 students at JHS 190, 48 had Calamari for lunch.
The percent that had Calamari for lunch would be calculated as:
= Number of students that had Calamari / Total students at JHS 190 × 100
= 48/150 × 100
= 32%
