3 x 1,000 + 7 x 10 + 3 x 1 + 2 x 1 / 100 + 4 x 1,000
3,000 + 70 + 3 + 1/50 + 4,000
7,073 and 1/50
The answer is 1,250 as you add all the items together
Answer:
x = 3.36
Step-by-step explanation:
, if we have a fraction = fraction then we can cross multiply to have a multiplication problem
x · 1 = 8 · 0.42, multiply
x = 3.36
Answer: He has 6 dimes and 2 nickels.
Step-by-step explanation:
If D is the number of dimes and N the number of nickels, we have that:
He has 8 coins:
D + N = 8
He has $0.70 in total:
D*0.10 + N*0.05 = 0.70
Then we have two equations, now we need to isolate one variable in one of the equations and then replace it in the other, let's isolate D in the first equation:
D = 8 - N
Now we can replace it in the other equation:
(8 - N)*0.10 + N*0.05 = 0.70
0.80 - N*(0.10 - 0.05) = 0.70
-N*0.05 = 0.70 - 0.80 = -0.10
N = 0.10/0.05 = 2
D = 8 - N = 8 - 2 = 6
He has 6 dimes and 2 nickels.
I can’t exactly find the answer. But if you don’t get any answers either hopefully this is helpful. I would pick 24.
