Plug in 9 where "a " is. so it reads "6x9+13" then solve. so 6x9=54 then 54+13=67
Answer:
1. 91 = 70*1.30
2a. 195= 150*1.30
2b. 210 = 150*1.40
3a. 56.70 = 156* .30
3b. 132.30 = 156-56.70
3c. 17.20 = 132.30 *0.13
3d. 149.50 = 132.30+17.20
3e. You do not have enough money, because you need $9.50 more.

Answer:
x = 4 and y = -1
Step-by-step explanation:
Given that,
6x+5y=19 ... (1)
2x+3y=5 ...(2)
We need to solve the above equations.
Multiply equation (2) by 3.
6x+9y=15 ...(3)
Subtract equation (1) and (3).
6x+5y-(6x+9y)=19-15
6x+5y-6x-9y = 4
-4y = 4
y = -1
Put the value of y in equation (2).
2x+3(-1)=5
2x-3=5
2x=8
x=4
So, the solution of the above equations are x = 4 and y = -1.
<span>Karen got an average of 0.444 hits out of 45 bats.
We need to find the number of hits did Karen got.
=> 45 bats all in all
=> 0.444 average hits
x = how many hit did she get
Now, let’s multiply the total bats to Karen’s average hit:
=> 45 x 0.444 …. (repeating decimals)
=> 20
Therefore, Karen hit 20 times out of 45 bats
Let’s check our answer:
=> 20 / 45
=> 0.44444…. (repeating decimals)
