Step-by-step explanation:
4x + 8y = 40
4x + (8×0.8) = 40
4x + 6.4 = 40
4x = 33.6
4x÷4 = 33.6 ÷ 4
x = 8.4
Answer:
$196
Step-by-step explanation:
Step one
given data
We are told that Noel bought a printer for $10 less than half its original price
let the original price be x
hence Noel paid = x/2-10= 88
Step two
amount paid= x/2-10= 88
Collect like terms
x/2= 88+10
x/2= 98
cross multiply
x=196
Hence the original price is $196
Let s =student
a =adults
now using the context to make an equation,
200s + 150a - 200 = 1000
the - 200 is the expenses you lost hosting the talent show.
now clean up the equation, add 200 to both side.
200s + 150a = 1200
Answer:
Step-by-step explanation:
15¾% = 63/4% = 63/400
First you need to find out what times 4 equals 8. You should know that it is 2 because 2×4=8. Then it should look like this
and that should be your answer or what ever your problem says to do.
Hope this helped :)
