What number you have to multiply 2 to get 5.
Or 2*x=5 solve for x
Answer:
Step-by-step explanation:
x= base
one side= x-6
other side= 4+x
x+x-6+4+x = 43
3x=43+2
x=15 length of base
I am so sorry I cannot help you with that because I am so bad at measurement I’m about to ask one myself
Answer:
Step-by-step explanation:
Set up two equations with the information given-- and things you know from experience: a penny is worth 1 cent and a nickel is worth 5 cents. $ 2.38 is 238 cents (so you can eliminate decimals for now)
Put those values into an equation about the total value:
p + 5n = 238
and you know the total number of coins is 66.
p + n = 66
get a value for p by "solving" (subtract n from both sides)
p = 66-n
Substitute that value for p in the first equation. Then solve.
(66 -n) + 5n = 238
4n = 238-66 Then isolate n by dividing both sides by 4
n = 172/4
n = 43 Substitute that in the second equation, then solve for p
p + 43 = 66 p = 66 - 43
p = 23
So Chuck has 23 pennies and 43 nickels
