Answer:
x = 65
Step-by-step explanation:
if two triangles are similar then we can use the similarity ratio to find the length of CH
60/156 = x/169 cross multiply expressions
156x = 10140 divide both sides by 156
x = 65
Answer:
7
Step-by-step explanation:
49(waterballoons) divided by 7=7groups
Answer:
x = 0
Step-by-step explanation:
I think you mean
The only undefined values of x come from the denominator, x^3.
A denominator cannot equal zero since division by zero is undefined.
Therefore if x^3 equals zero, you get an un defined expression.
We let x^3 = 0 and solve for x to find the values of x that would cause an undefined expression.
x^3 = 0
Solve for x by taking the cubic root of both sides.
x = 0
Answer: x = 0
Answer: m= 100+5w
m= 80+7w
Step-by-step explanation:
Let w = number of weeks , m = Money required to buy DVD.
Total money = (Initial saving) + (Money saved per week) x (Number of weeks)
For Amir,
initial saving = $100 , Money saved per week = $5
So, m= 100+5w
For Pete,
initial saving = $80 , Money saved per week = $7
So, m= 80+7w
So, the required system of equations to find m and w:
m= 100+5w
m= 80+7w
