June has 42 sports books, 85 mystery books, and 69 nature books. She arranged her books equally on 7 shelves. How many books are on each shelf.
Answers
Answer:
28
Step-by-step explanation:
We are given that
June has sports books=42
June has mystery books=85
June has nature books=69
Total number of shelves=7
We have to find the number of books are on each shelf.
Total number of books=42+85+69=196
To find the number of books on each shelf we will divide the total number of books by 7.
Number of books on each shelf=
Number of books on each shelf=28
Hence, number of books on each shelf=28
Answer:
28
Step-by-step explanation:
Add 42, 85, and 69 together and you get 196 but you need to divide that by 7 and you get 28

Let the number = x
12 + x = 3x - 32
x = 3x - 44 Subtract 12 from both sides
-2x = -44 Subtract 3x from both sides
x = 22 Divide by -2
Because 12 +22=34 then use the amth to do minus 32 less than 3 times tghe number

Answer:
The expression is equal to 12.
Step-by-step explanation:
First of all, compute the parenthesis.
18 / 6 = 3
Now, replace 18/6 with 3 in our expression.
Next, compute the multiplication.
-12 * 3 = -36
Again, we'll replace that multiplication with negative 36:
Since subtracting a negative number is the same as adding a positive number:

(x + a)/ax = b/x
therefore: a != 0, x !=0
now we solve:
(x + a)/ax = b/x
(x + a)/a = b
x + a = ab
x = a(b - 1)
that is the solution for b, and we keep in mind that a != 0, x !=0, the extraneous solutions

Amount he must save to earn his goal = $7193.1≅
Step-by-step explanation:
The 5.5% interest is compounded quarterly, hence the compound interest expression is used
A = P(1+r%)ⁿ
A = $26000
P = ?
r = 5.5%
n = 4 x 6 = 24 quarters
P = A ÷ (1+r%)ⁿ = 26000 ÷ (1 + 0.055)²⁴ = 7193.070497956 = $7193.1≅
