On one shelf of the school library 1/2 of the books are about sports. Joyce sees that 3/4 of the sports books are about basketball. What fraction of the books on the shelf are about basketball
Answers
The fraction of books on the shelf that are about basketball is [tex]\frac{3}{8}[/tex].
We know that half of the books on the shelf are about sports, so if we let "x" represent the total number of books, the number of sports books would be [tex](\frac{1}{2})x[/tex].
Next, Joyce observes that [tex]\frac{3}{4}[/tex] of the sports books are about basketball.
To find the fraction of books about basketball, we need to multiply the fraction of sports books by the fraction of basketball books within that category.
Therefore, we have:
[tex](\frac{3}{4}) \times(\frac{1}{2} )x =(\frac{3}{8} )x[/tex]
So, the fraction of books on the shelf that are about basketball is [tex]\frac{3}{8}[/tex].

2x + 9(x – 1) = 8(2x + 2) – 5
Answers
Answer:
Yes it is!
Step-by-step explanation:
All you have to do is plug in -4 in place of all the x’s. You should get
-8x - 36 - 9 = -64x + 16 - 5
Simplified: -8x - 45 = -64x + 11
+45. + 45
-8x = -64x + 56
+64 +64
56 = 56
Answer = True
So yes -4 is a correct solution!
2x +9x -9 = 16x + 11
11x - 9 = 16x + 11
11x = 16x + 20
-5x = 20
x = -4

Answers
Answer:
$ 1,732.04
Step-by-step explanation:
A = $1,732.04
I = A - P = $725.04
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year.
Solving our equation:
A = 1007(1 + (0.08 × 9)) = 1732.04
A = $1,732.04
The total amount accrued, principal plus interest, from simple interest on a principal of $1,007.00 at a rate of 8% per year for 9 years is $1,732.04.

Each month, a phone company charges $30 talk time plus $0.50 for each additional minute.
Write an expression to show the cost of a plan for one month???
Answers
Answer:
Step-by-step explanation: If 1 minutes of talk = 30 and texting = 30
and each additional minute of talk = 0.50
then the bill would be (for C = total cost)
C = 20+30+(0.45 • x)
OR
C = 50 + 0.45x
Answer:
30+.50m=c
Step-by-step explanation:
30 is the initial cost. Since its initial it is only a one time fee.
.50 is the cost per minute, since it says per you can automatically assume that it will be more than once.
M represents the minutes that they spend on the call, so if there was a 10 minute call, instead of m you would put 10, 10×.50.
But since there is no given time we have to put a variable, m, as a replacement.
The c is the variable for the cost.

the ordered pair (1,-3) is a solution of the system
Answers
Answer:
False
Step-by-step explanation:
Find the solution of:
2x + 3y = -7 --› eqn. 1
-x = 2y --› eqn. 2
Rewrite equation 2
-x = 2y --› eqn. 2
Divide both sides by -1
x = -2y
Substitute x = -2y in equation 1.
2x + 3y = -7 --› eqn. 1
2(-2y) + 3y = -7
-4y + 3y = -7
-y = -7
Divide both sides by -1
y = 7
If y = 7, then (1, -3) cannot be the solution of the system of equations.
