Answer: They are 59 members in the band
Step-by-step explanation:
given data:
when lined up in 3 = 2 left.
when lined up in 4 = 3 left
when they are lined up in 5 = 4 left
when they are lined up in 6 = 5 left
Solution:
From the given data, we know the band number ends with 9, so we start with 9,29,49,59. We test till we arrive at our desired answer.
59/3 = 19 R 2.
59/4 = 14 R 3.
59/5 = 11 R 4.
59/6 = 9 R 5.
They are 59 members in the band.
The value of x is B.4 I think
Given:
tickets for adults - 25
tickets for kids - 15
initial cost - 450
increase in tickets for kids to - 18
cost after increase - 480
let x be number of adults and y be number of kids
25x + 15y = 450
25x + 18y = 480
subtraction:
25x + 15y = 450
<u>-25x - 18y = -480</u>
0 - 3y = - 30
y = -30/-3
y = 10
There are 10 kids.
25x + 15y = 450
25x + 15(10) = 450
25x + 150 = 450
25x = 450 - 150
25x = 300
x = 300/25
x = 12
There are 12 adults.
All in all there are 12 adults and 10 kids.
to check:
25x + 15y = 450
25(12) + 15(10) = 450
300 + 150 = 450
450 = 450
25x + 18y = 480
25(12) + 18(10) = 480
300 + 180 = 480
480 = 480
Answer:
90 pieces
Step-by-step explanation:
If a 6-ounce bag of fruit contains 45 pieces, then a bag two times larger than that bag would likely also be two times larger than how many pieces were in that bag. 45 x 2 = 90.
