Tommy bought a total of 20 game cards some of which cost $0.25 each and some of which cost $0.15 each. If Tommy spent $4.20 to buy these cards,how many cards of each type did he buy?
Answer:
He bought 12 cards that cost $0.25 and 8 cards that cost $0.15.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=20 (1)
0.25x+0.15y=4.20 (2)
First, you can solve for x in (1):
x=20-y (3)
Now, you can replace (3) in (2):
0.25(20-y)+0.15y=4.20
5-0.25y+0.15y=4.20
5-0.10y=4.20
5-4.20=0.10y
0.80=0.10y
y=0.80/0.10
y=8
Finally, you can replace the value of y in (3) to find x:
x=20-y
x=20-8
x=12
According to this, he bought 12 cards that cost $0.25 and 8 cards that cost $0.15.

Which number line shows the solution to inequality 3x – 3 < 12?
Answer:
A
Step-by-step explanation:
The Graph "A" show the value of x in inequality 3x – 3 < 12
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
What does open circle and close circle shows in graph?A closed circle indicates "greater than or equal to" or "less than or equal to," while and open circle indicates "greater than" or "less than".
According to the question
Given inequality 3x – 3 < 12
Solving for x
3x – 3 < 12
3x < 12 + 3
3x < 15
x < 5
Open circle will be used to show the greater than sign
Therefore,
Graph A shows the inequality .
Hence, the Graph "A" show the value of x in inequality 3x – 3 < 12

The formula
C = 9f + 4p + 4c
gives the number of calories C in a serving of food that contains f grams of fat, p grams of protein, and c grams of carbohydrate.†
Find the number of grams of protein in an 8-ounce serving of vanilla yogurt that contains 179 calories, 3 g of fat, and 31 g of carbohydrate.
g
Answer:
7 grams of protein
Step-by-step explanation:
C = 9f + 4p + 4c
Plug the given information into the given formula
179 = 9(3) + 4p + 4(31)
Use PEMDAS
179 = 27 + 4p + 124
Combine like terms
179 = 151 + 4p
Subtract both sides by 151 to isolate variable p
179 - 151 = 4p
28 = 4p
Divide both sides by 4 to isolate variable p
28 ÷ 4 = p
7 = p
