1) this is simply solving it, so if you divide 16 by 3, you end up getting 5 1/3
2) 3 1/2, by multiplying 7 by 1/2
3) 224, by multiplying 14 by 16
4) 54 mph, by dividing 324 by 6
5) blue, because only the 1/4 ribbon color would be collected after 3/4 mile
6) 7/8 - 3/8 equals 4/8, or 1/2 when simplified
TTese are all parabolas whose axis of symmetry is the y axis. The negative coefficient means they open downwards and the positive mean they open upwards. The higher the absolute value of the coefficient is the greater the slope, so 2x^2 will be steeper than x^2 and -4x^2 will be steeper than - 2x^2.
So h(x) and j(x) are the answers.
Out of 40 respondents, 7 attend afterschool programs.
, so 17.5% of students attend afterschool programs.
.
So, out of 200 seventh-graders, 35 would be expected to attend afterschool programs.
Isosceles triangle
so
x + 8 = 2x -1
x = 9
BC = 3x - 3
BC = 3(9) - 3
BC = 27 - 3
BC = 24
Answer:
Leroy has $1.20 , Aaron has $6.00
Step-by-step explanation:
let Leroy have x , then Aaron has 5x , so
x + 5x = 7.20
6x = 7.20 ( divide both sides by 6 )
x = 1.20
Then
Leroy has $1.20 and Aaron has 5 × $1.20 = $6.00
