5/8x + 1/5x =66 what does X equal?

Answers

Convert the fractions so they have the same denominator of 40. This will make the equation 25/40x + 8/40x =66.
Add the two numbers to get 34/40x =66
Divide 66 by 34/40 to get x= 77.65 or 77 11/17

Answer:

x = 80

Step-by-step explanation:

Find a common denominator for 5/8x and 1/5x

25/40x + 8/40x = 66

Add 25/40x and 8/40x together.

33/40x

33/40x = 66

Divide both sides by 33/40

x = 80

In ten-pin bowling, the highest possible score in a single game is 300. At one point in the bowling season, Fred F Stone had an average score of 177. In his next game he obtained a score of 199, which caused his average to increase to. 178. After one more game Fred would like his average to be 183. Is it possible for Fred

Answers

Let, number of games played is n and sum of their points are x.

So, [tex]177=\dfrac{x}{n}[/tex]    

Now, In his next game he obtained a score of 199, which caused his average to increase to 178.

[tex]178=\dfrac{x+199}{n+1}[/tex]

Now equations are :

x = 177n    ...1)

x + 199 = 178( n + 1 )

x = 178n - 21  ...2)

Solving eq 1 and 2 , we get :

x = 3717 and n = 21 .

Now, new average is 183.

Let, point scored in last game is y.

So,

[tex]183 =\dfrac{x+y}{n+1+1}\\\\183 = \dfrac{3717+y}{23}\\\\y = 183\times 23 - 3717\\\\y=492[/tex]

He required 492 points which is greater than the maximum i.e 300.

Therefore, it is not possible for Fred.

Hence, this is the required solution.

The city council budgeted $2,784 to buy new garbage cans. If each garbage can costs $96,
how many garbage cans will the city be able to buy?

Answers

Answer:

29 trash cans!

Step-by-step explanation:

Hello!

To solve this, we simply divide the budget by how much each garbage can costs. This will tell us how many times 96 goes into 2,784, and thus, how many they can buy.

$2,784 ÷ $96 = 29!

So, they can buy 29 trash cans with that budget!

Answer:

x = 5

divide both sides by 0.5:

x = 5

Is the x intercept always the same as the slope?

Answers

Answer:

We can use the slope-intercept form (y = mx + b). The x-intercept is found by setting y = 0, because that will give us the x-value at which the line crosses the x-axis.

Step-by-step explanation:

Answer:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).
