Answer:
132 children and 88 adults
Step-by-step explanation:
let x represent the amount of kids and y represent the amount of adults.
since the problem says there was a total of 220 people at the fair an equation can be made
x+y=220
the problem tells that each childrens ticket was 1.5$ and each adult ticket was $4 and that a total of $550 was made that day, we can use the knowledge to make an equation:
1.5x + 4y = 550
using the equations we can make this systems of equations:
1.5x + 4y =550
x + y =220
solve the systems of equations by subracting y on both sides of th bottom equation:
x=220-y
since x is equivant to 220-y it can be substitued for x in the first equation to make this:
1.5(220-y)+4y =550
--solve for y--
y=88 - there were 88 adults
substute 88 for y in the second equation
x+88=220
--solve for x--
x=138 - there were 132 children
Answer:
1000, 2000, 3000, .... etc are the 4-digit numbers which when divided by 1000, give whole number answer.
Step-by-step explanation:
Scott divides some 4- digit numbers by 1000 and his answer is a decimal every time.
From this Scott has concluded that if you divide a 4-digit number by 1000, then the answer will never be a whole number.
I think Scott is wrong and the reason is that if we try to divide those 4-digit numbers which are multiples of 1000, i.e. 1000, 2000, 3000, 4000, ... etc. with 1000 then only you will get a whole number answer. (Answer)
Answer:
Step-by-step explanation:
we are given a square and rectangle.we want to figure out x which is the width of the rectangle. we are also given a condition i.e
- the area of the square equal to the area of the rectangle
therefore,
recall the formula of the area of square and rectangle so,
now assign variables
thus substitute:
simplify square:
divide both sides by 32:
and we're done!
