Answer:
10 
s*0.25 + a*0.75
Step-by-step explanation:
Assign variable for each game
s = number of Skeeball games
a = number of Air hockey games
Then write out what you know...
1. Total cost of Skeeball = s*0.25
2. Total cost of Air hockey = a*(3*0.25) -> a*0.75
So the inequality would be...
10 s*0.25 + a*0.75
The area of a trapezoid can be found with this formula:
Where b1 and b2 are the bases and h is the height.
If we plug in what we know we can solve for the height.
We know that b1 = 52, b2 = 42, and A = 1833. Let's solve.
Answer:
-63
Step-by-step explanation:
6x - 3y
= 6 × -4 - 3 × 13
= -24 - 39
= -63
Answer:
14
Step-by-step explanation:
So, if x is length, then x*x*8 is 1568. To solve, you do 1568/8, which gives you 196. The square root of 196 is 14, and 14*14*8 is 1568.
Answer:
B.
Step-by-step explanation:
Try solving:
13x - 5 = - 5 + 13x
13x - 13x = -5 + 5
0 = 0.
Therefore it is an identity.
We could make x any real value and the identity would hold.
