Answer:
9
Step-by-step explanation:
percentages are reversable. like instead of 18% of 50 you could reverse it and say what is 50% of 18. which is 9.
P = ab^2
q = a^3 b
p = a * b * b
q = a*a*a * b
Pairing the duplicates we have LCM = a*a*a*b*b = a^3 b^2 answer
Answer:
y=2x+6 ; x+y=51
Step-by-step explanation:
assuming x is one number and y is the other -
one number (y) is 6 more (+6) than twice another (2x) -
using that knowledge we form an equation -
y=2x+6
the sum (x+y) is 51
using this knowledge we can make the equation -
x+y=51
now you have -
y=2x+6 or 2x-y=-6
x+y=51
using system of equations -
you add the equations -
3x=45
x=15
y=51-x => y=36

Answer: 288 students
Step-by-step explanation:
<u>First Step: find the number of students per bus</u>
Given
- 144 students
- 4 bus
Solve
144 students/4 buses=36 students/bus
<u />
<u>Second Step: apply the rate to find the number of students in 8 buses</u>
Given
- 8 buses
- 36 students/bus
Solve
8×36=288 students
Hope this helps!! :)
Please let me know if you have any questions
(x,y)
y=mx+b
m=slope
b=yintercept
slope=7/10
one point is (1,2) or x=1, then y=2
find b
y=7/10x+b
2=7/10(1)+b
2=7/10+b
minus 7/10 both sides
1 and 3/10=b
13/10=b
y=7/10x+13/10
input values for x and get values for y
one point is (0,13/10)
