Answer:
A/15=5
so multiply 15*5
you would get 75
therefore a=75
Step-by-step explanation:
Substitution method is one of the ways to solve this system.
-5x+y=4 and 4x-4y=16.
First we will divide the second equation with number 4 and get
x-y=4 => x=y+4 than we will replace x in the first equation
-5(y+4)+y=4 => -5y-20+y=4 => -4y=4+20 => -4y=24 => y=-6
x-(-6))=4 => x+6=4 => x=4-6=-2 (x,y)=(-2,-6)
Good luck!!!
Answer:
a) $12
b) $0.17
c) $1.65
Step-by-step explanation:
a) 3 movie tickets cost $36. At this rate, what is the cost per ticket?
3 movie tickets = $36
1 ticket = x
Cross Multiply
3x = $36
x = $36/3
x = $12
Therefore, the cost per ticket = $12
b) 3 ice cream cones cost $.25. At this rate, how much do 2 ice cream cones cost?
3 ice cream cones = $0.25
2 ice cream cones = x
Cross Multiply
3x = 2 × $0.25
3x = $0.50
x = $0.50/3
x = $0.1666666667
Approximately = $0.17
Therefore, the cost of 2 ice cream cones = $0.17
c) 3 bananas cost $0.99. At this rate, how much do 5 bananas cost?
3 bananas = $0.99
5 bananas = x
Cross Multiply
3x = 5 × $0.99
x = 5 × $0.99/3
x = $1.65
Therefore, the cost of 5 bananas = $1.65
Answer:
14 ounces!
Step-by-step explanation:
It's actually quite simple, it's easy too overlook these questions but don't worry, I will help
All you really have to do is count up, what I do is temporarily forget about the fractions I focus on the main number (which in this case is 4) you want to times 4 by the amount of children so (3) 4×3=12
Now the fraction part, all you have to do is count up! 2/3, then 3/3 then 1 1/3 then 1 2/3 then 2!
Now add the original number by the result of the fraction number so 12+2= 14!
