Answer:
3 soccer trophies does Joel have
Step-by-step explanation:
As per the statement:
Joel has 24 sports trophies.
⇒Total sport trophies Joel have= 24
It is also given: of the trophies, 1/8 are soccer trophies
We have to find how many soccer trophies does Joel have.
Simplify:
Therefore, 3 soccer trophies does Joel have
= -3/2 * -5 1/4
convert 5 1/4 to improper fraction
= -3/2 * -21/4
multiply numerators; multiply denominators
= (-3*-21)/(2*4)
multiply in parentheses
= 63/8
convert back to mixed number
= 7 7/8
ANSWER: Since the exact answer is the mixed number 7 7/8, a reasonable estimate is 8.
Hope this helps! :)
Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
