Answer: You can buy 5 cans of tennis balls.
Step-by-step explanation: 100 minus 80 is 20 and that leaves $20 for tennis balls, so 20 divided by 4 is 5 and that's how many cans you can buy.
Answer:
3, 8 and 24.
Step-by-step explanation:
Let's write some equations that satisfy this problem (x = smallest, y = middle, z = largest):
z = 3y
x + y + z = 35
x = y - 5
We can use substitution to solve this problem! I will take x + y + z = 35, replace x with y - 5 (since we know x = y - 5) and replace z with 3y (since we know z = 3y).
This leaves us with:
(y - 5) + y + (3y) = 35
y - 5 + y + 3y = 35
5y - 5 = 35
5y = 40
y = 8
Since we know y (the middle number) is 8, we can now find the other numbers:
Largest is 3 times the middle, so 8 * 3 = 24.
Smallest is 5 less than the middle, so 8 - 5 = 3.
The 3 numbers are therefore 3, 8 and 24.
Answer:
Yes.
Step-by-step explanation:
Because sides are parallel, corresponding angles are congruent (angle W = angle V and angle U = angle T). By the third angle theorem (or you can use the reflexive property if that's easier), angle S = angle S. To determine triangles as similar, all angles must be congruent, and all sides must be equally proportional. This is true here because all of the angles are equal, so all of the sides must be proportional (I don't remember the theorem here)
To get the answer of x, use the proportional formula (UW/TV = US/TS). So (12/3)=(9/x), 4 = 9/x, 4x = 9, x = 9/4.
