Answer:
the y value equals 5
Step-by-step explanation:
(x,y)so
plug in 8 for x
5(8)=40
40 -2y=30
subtract 40 from both sides
-2y=-10
divide by -2
y=5
Y=50-3.25X after 12 lunches it would have a value of 11$
Answer:
5/24
Step-by-step explanation:
Start with the first part of the probelm 5/6 - 2/3
You need to find a common denominator of 6 and 3
common denominator= 6
so change 2/3 to 4/6
now you can subtract the top values
5/6-4/6
5-6=1
keep the denominator the same
= 1/6
Now divide 1/6 by 4/5
to divide you are going to multiply by the reciprocal so instead of 4/5 we are going to flip it to 5/4
1/6 x 5/4
5x1=5 and 6x4=24
= 5/24
25 ÷ (6 - 1) = 25 ÷ 5 = 5, she saved 5 nickels,
5 nickels = 5 × 5 = 25 cents = $0.25
5 + 25 = 30, she saved 30 dimes, 30 dimes = 300 cents = 3 dollars.
3 + 0.25 = $3.25, she saved $3.25 in all.
