1(5) + 4(X) = 25
5 + 4X = 25
subtract 5 from both sides
4X = 25 - 5
4X= 20
divide both sides by 4
X = 20/4
x=5
Each eraser cost 5$

You bought a magazine for $5 and four erasers. you spent a total of $25.

Magazine cost: 5$ each
Eraser cost: X$ each

Total cost is the number of items (1 magazine) times the cost of each item (5$). We don't know the cost of each eraser, so we represent that using a variable, X.

1(5) + 4(X) = 25

5 + 4X = 25

subtract 5 from both sides

4X = 25 - 5

4X = 20

divide both sides by 4

X = 20/4

X = 5

Each eraser cost 5$

Find the product with the exponent in simplest
fgiga [73]

Answer:

x = 7

y = 12

Step-by-step explanation:

The key to solving this problem is understanding the properties of exponents:

If you are multiplying two powers with the same base (in this case the base is 6), the result is the base raised to the power of the two exponents added together.

6^1/3+1/4 = 6^x/y

6^7/12 = 6^x/y

So the product would be 6^7/12

Therefore, the answers are:

x = 7

y = 12

A cyclist rides his bike at a speed of 18 miles per hour. What is this speed in kilometers per hour? How many kilometers will th
Sonja [21]

Well, if 1 mile = 1.6 kilometers and he's traveling at 18mph, then do 18 x 1.6 which = 28.8.

So, this is his current speed in kph

3 x 28.8 = 86.4‬

They will have traveled 86.4‬ kilometers

(I haven't worked with this kind of math in a while so correct me if I'm wrong!)

A basketball coach collected data to analyze the free throw shooting percentages of players during a game and during practice. T
Dima020 [189]

Answer: The correct answer is option A; 78

Step-by-step explanation: The equation representing the line of best fit which is given as

y = 0.9x - 1

depicts the relationship between a player's practice results and actual game results. Whatever value is given as x which is the result from practice would be a good way of predicting a player's result when engaged in the real game.

For the question above, a player with  a practice shooting percentage of 88 would have his game shooting estimated by simply inserting the value of his practice percentage into the equation showing the line of best fit shown as follows;

y = 0.9x - 1

Where x = 88

y = 0.9 (88) - 1

y = 79.2 - 1

y = 78.2

y ≈ 78

Therefore the approximate shooting percentage for a player with a practice shooting percentage of 88 would be 78 percent.
