Answer:
8
Step-by-step explanation:
So. Let's plug in 2 for y. 7(2)-3(2). Before we subtract, let's multiply first. 7 times 2 is 14 and 3 times 2 is 6. So now the equation looks like this: 14-6. From here, you do regular subtraction to get 8. Hope this helps!

Shaggy earned 7.50 an hour plus an additional $100 in tips waiting tables last night. He earned more than $160 in all. Write an inequality to represent this situation and help you find the number of hours (h) he worked.
Answer
x>21.2
Step-by-step explanation:
7.55x+100>160:
subtract 100 on both sides to get:
7.55x>60:
divide 7.55 on both sides:
x>21.2 is your answer
Answer:
7.50h + 100 > 160
Step-by-step explanation:
7.50 is the hourly wage
h = hours he worked
add 100 once because it's his tips for the amount of time her worked
since he worked more than 160, you'll use the greater sign
then solve for h
h = 8 hours

Carmen runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?
Answer:
4.2 miles
Step-by-step explanation:
6 miles/50 minutes = x miles/35 minutes
1. Since 5 is the GCF (greatest common factor) of x and 35, that is what the ratio must first be converted into, by dividing by 10: 6/50 = 0.6/5
2. To convert this to 35 minutes, it must be multiplied by 7, because 5 * 7 = 35. This leaves us with the answer:
0.6/5 = 4.2 miles/35 minutes

(b) What per cent is1/2
dozen of one score?
Answer:
1/2 dozen of one score is 30%.
Step-by-step explanation:
As we know that 1 dozen = 12 units.
1/2 dozen = 1/2 times 12=6 units
1 score = 20 units.
By using this conversion, we get
6/2 times 100=30%
So 1/2 dozen of one score is 30%

Step-by-step explanation:
Mario plays basketball on a town league team. The
table below gives Mario's scoring statistics for last
season. How many points did Mario score playing
basketball last season?
Answer:
Step-by-step explanation:
Total points Mario scored = total 1-point free throw + total 2-point field goal + total 3-point field goal.
In 80 attempts 1-point free throw, Mario had 75% success rate. That is, Mario had 80 x 75/100 success
80 x 75/100 = 60
Thus, Mario scored 1 x 60 (since for each success, 1 points is added) points = 60
In 60 attempts 2-point field goal, Mario had 90% success rate. That is, Mario had 60 x 90/100 success
60 x 90/100 = 54
Thus, Mario scored 2 x 54 points (since for each success, 2 points are added) = 108
In 60 attempts 3-point field goal, Mario had 25% success rate. That is, Mario had 60 x 25/100 success
60 x 25/100 = 15
Thus, Mario scored 3 x 15 points (since for each success, 3 points are added) = 45
Therefore, the total points Mario scored = 60 + 108 + 45
= 213

Answer:
UT = 8
Step-by-step explanation:
From the picture, we can make the following equation...
5 + 2x - 6 = x + 6
By solving it we get
5 + 2x - 6 = x + 6
2x - 1 = x + 6
2x = x + 7
x = 7
Therefor if UT = 2x - 6, then UT is equal to...
2x - 6 = UT
2(7) - 6 = UT
14 - 6 = UT
8 = UT
