what graph show me the graph
Step-by-step explanation:
Given ratio : 90 lbs on earth :15 lbs on the moon.
Let us write 90 lbs :15 lbs in fractions first.
90:15 = 90/15
Now, in order to determine different strategy, we need to find any equivalent fraction/ratio of the given fraction or ratio.
In order to find an equivalent fraction or ratio, we need to find a common number that can divide( even we can multiply) both numerator (top number) and denominator (bottom number).
For the given ratio 90/15, we can divide 90 and 15 both by 15.
90 ÷ 15 = 6
15 ÷ 15 = 1
Therefore, 90 lbs on earth :15 lbs on the moon could be written as 6 lbs on earth :1 lbs on the moon.
Which question? The picture is black
Answer:
Jack is 6 and Mom is 30
Step-by-step explanation:
J = Jacks age
M = Mom's age
5J = M
In 6 years, so add 6 to the age
3(J+6) = (M+6)
We have a system of 2 equations and 2 unknowns
Lets simplify the 2nd equation
3(J+6) = (M+6)
3J + 18 = M+6
Substituting M =5J
3J + 18 = 5J +6
Subtract 3J from each side
3J-3J + 18 = 5J-3J +6
18 = 2J+6
Subtract 6 from each side
18-6 = 2J+6-6
12 = 2J
Divide each side by 2
12/2 = 2J/2
6=J
Jack is 6
We still need to find Mom's age
M = 5J
= 5*6
=30
Mom is 30
Answer:
The number of possible color combinations that she can make = 6
Step-by-step explanation:
The number of available colors = 3
The question states that Maria only uses a color on each shape at a time,
The number of possible color combinations that she can make = 3!
n! = n*(n -1)*(n-2)*......*1
3! = 3 * 2 * 1
3! = 6 combinations
The number of possible color combinations that she can make = 6
