Answer:
In the end Joanne had 55 sweets.
Step-by-step explanation:
Let the number of sweets that Xue Ying had be y and let the number of sweets Joanne had be x.
It is given that Xue Ying had 143 more sweets than Joanne. We can write this information as an equation.
y = x + 143.
It is also given that Joanne gave away 22 of her sweets and after that Xue Ying had 6 times as many more sweets. We can write this as an equation.
y = 6(x - 22) = 6x - 132.
Therefore we can equate the two equations and solve for x.
x + 143 = 6x - 132
5x = 275
∴ x =
sweets.
Therefore in the end Joanne had 55 sweets.
The proportion that could be used to solve for the variable is
; h = 7.5 ⇒ answer b
Step-by-step explanation:
A proportional relationship: one variable is always a constant value times the other, that constant is called the constant of proportionality
- y = k x is the equation of the proportional relationship
- We can write the proportional relationship in the form
The number of walls and the number of hours are increased or decreased together
∴ The number of walls and the number of hours are proportion
∵ 16 walls in 40 hours
∵ 3 walls in h hours
- By using the second rule above
∴
The proportion that could be used to solve for the variable is
Let us solve it to find h
∵
- By using cross multiplication
∴ 16 × h = 3 × 40
∴ 16 h = 120
- Divide both sides by 16
∴ h = 7.5
The value of h is 7.5 hours

Answer:
- Angle-Angle-Angle(AAA)
- Side-Angle-side(SAS)
Step-by-step explanation:
Let's see what is similar in both triangles
So Angle-Angle-Angle similarly theorem verified
So Side-Angle-side or Side-Side-Side similarity theorem verified
Answer:
I'm pretty sure it's 1 cup of water
You need 2 cups of pancake mix more than water so if you have 3 cups of pancake mix then you'd need 1 cup of water.
6 cups of mix = 4 cups of water
the cups of the mix is are 2 more cups than the water
3 cups of mix = 1 cup of water
I hope that helps and good luck! :)
