I have 14 Baseballs in 23 tennis balls and some boxes of baseballs with 12 baseball and I have the equal amount of boxes of tennis balls and 16 ball write an expression to represent the total number of balls
Answer:
The answer is below
Step-by-step explanation:
I have 14 Baseballs in 23 tennis balls. I bought some boxes of baseballs with 12 baseball to a box and equal amount of boxes of tennis balls with 16 balls to a box. write an expression to represent the total number of balls
Solution:
Let n represent the number of boxes of each type.
Given, the number of boxes of tennis = number of boxes of baseball, hence:
n = number of boxes of tennis = number of boxes of baseball.
Already I have 14 baseball and I bought boxes of baseballs with 12 baseball to a box, therefore:
Number of baseballs = 14 + 12n
I have 23 tennis ball and I bought boxes of tennis balls with 16 baseball to a box, therefore:
Number of tennis balls = 23 + 16n
Total number of balls = number of baseballs + number of tennis balls
Total number of balls = (14 + 12n) + (23 + 16n) = 14 + 23 + 12n + 16n = 37 + 28n
Total number of balls = 37 + 28n

Answer:
80 mStep-by-step explanation:
The described points form two right triangles which share same horizontal leg a.
The bottom triangle has 60 m vertical length and 60° opposite angle.
The triangle on the top has unknown (x) vertical length and 30° opposite angle.
We are looking for the distance x + 60 m
On the top triangle we have:
tan 30° = x/a ⇒ a = tan 30° / xOn the bottom triangle we have:
tan 60° = 60/a ⇒ a = tan 60° / 60Comparing we get:
tan 30° / x = tan 60° / 60 x = 60 tan 30° / tan 60°x = 20 mSo the distance is:
60 m + 20 m = 80 mhow do you simplify this

(Graph is in the picture)
Answer:
y = 3x + 4
Step-by-step explanation:
y = mx + c where m is the slope and c is the y intercept.
Slope = [tex]\frac{rise}{run}[/tex]
Slope (taken from points (0, 4) and (1, 7)) = [tex]\frac{7-4}{1-0}[/tex]
= 3
y-intercept = 4

FroYo Express charges $5.75 for a large cup of frozen yogurt and $0.25 for each topping. The Big Chill charges $2.75 for a large cup of frozen yogurt and $1.25 for each topping.
The graph represents the relationship between the number of toppings, x, and the total cost of a large cup of frozen yogurt, y, at the two stores.
For what total cost are the number of toppings the same at both stores?
Answer:
3 toppings for a total of $6.50
Step-by-step explanation:
Based on the information provided we can calculate the cost of a yogurt using the following equations for both Froyo Express (F) and The Big Chill (B) , where the variable x represents the number of toppings...
F = 5.75 + 0.25x
B = 2.75 + 1.25x
Now that we have both equations we can simply make one equal to the other and solve for x in order to calculate at what number of toppings the prices will be the same...
5.75 + 0.25x = 2.75 + 1.25x ... subtract 2.75 and 0.25x on both sides
3 = 1x ... divide both sides by 1
3 = x
Finally, we can see that at 3 toppings the total cost of both stores will be the same at $6.50
