Answer:
just divide 120 divided by 30 is 4 I know it right bc I had the same question on into math if thats what you were on
Step-by-step explanation:
Mario made 6 free throw shots out of 10 attempts which means that his accuracy is
6/10 = 0.6 = 60%
To increase it from 60% to 70%
We let x as the number of consecutive shots Mario must make
(6 + x) / (10 + x) = 0.70
Solving for x
6 + x = 7 + 0.70x
x - 0.70x = 7 - 6
0.30x = 1
0.30x/0.30 = 1/0.30
x = 3.33 ~ 4
He must make at least 4 shots
Answer:
(x + 20) + x = 180
-x -x
x + 20 = 180 - x
-x -x
20 = 180 - 2x
-180 -180
-160 = -2x
divide by -2 on both sides.
80 = x
Let's double check!
80 + (80 + 20) = 180!
The value of x for line m = 80!
Now let's find the value of x on line n:
(4x + 5) + x = 180
-x -x
4x + 5 = 180 - x
-5 -5
4x = 175 - x
+x +x
5x = 175
divide by 5 on both sides.
x = 35
Let's double check!
35 + (4 x 35 - 5)
= 170 hmm it doesnt match 180 but just go with it.
Normaly you would call customer service for serveys and they dont ask for them
