The answer is: -11/3
8/4 * 11/-6
Multiplying an odd number of negative terms makes the product negative
-8/4 * 11/6
Reduce the numbers with the greatest common factor
-2 * 11/6
2 cancels out -2; divide 6 by 2
= -11/3
The dog weighs 10 pounds and the cat weighs 5 pounds
X=number of boys in the club at first
y=number of girls in the club at first.
(x+y) = members were in the club at first.
We can suggest the next system of equation.
x/y=1/2 ⇒ x=y/2
(x+5)/y=3/4 ⇒4(x+5)=3y
Finally, we have the next system of equations:
x=y/2
4(x+5)=3y
We are going to solve by substitution method.
4(y/2 + 5)=3y
2y+20=3y
2y-3y=-20
-y=-20
y=20
x=y/2
x=20/2
x=10
(x+y)=10+20=30
Answer: There were 30 members int the club at first, they were 10 boys and 20 girls.
Answer:
12 days of frog food.
Step-by-step explanation:
3/(1/4) = 3 * 4 = 12 days
Answer:
12
Step-by-step explanation:
if the perimeter is 54, and the length is 15,
first double the length (to include both sides of the rectangle):
15(2)=30
subtract that by 54:
54-30=24
to find the width we would divide 24 by 2, because 24 represents both sides of the rectangle:
24/2=12
the width is 12.
