Answers
Answer:
C
Step-by-step explanation
Answer:
C.)
Step-by-step explanation:
First, let's make it so that 6/8 and 4/5 have the same denominator.
Find the LCM: 40
8 ÷ 40 = 5
5 ÷ 40 = 8
Now that we have this info, let's convert the numerator to match the denominator.
4/5:
4 × 8 = 32
So... 4/5 = 32/40
6/8:
6 × 5 = 30
So... 6/8 = 30/40
Now let's add:
30/40 + 32/40
30 + 32 = 62
Therefore: 62/40
Now let's add those whole numbers: 5 + 4 = 9
Our answer: 9 62/40
Let's simplify: 10 22/40
Therefore, C is the correct answer.
Consider the equation 5x + 7 = 2x + 28. Your tasks to explain the steps you would take, in
order, to solve the equation for x. Imagine that you are writing this for someone who is learning
about this process for the first time. You would be as specific as possible and write in complete
sentences.
Answers
Answer:
x=7
Step-by-step explanation:
Step 1: Put the variables and constants on the same side and change their signs so it'll look like this 5x-2x = 28 - 7, you always move the smaller number to either the left or right depending on its position in the problem.
Step 2: solve each side normally like this, 3x = 21
Step 3: to get x by itself divide 3 on both sides and you should get x=7
Here's a run through of the steps
5x+7=2x+28
-7 -7(subtract 7 from both sides
5x=2x+28-7
-2x -2x(subtract 2x from both sides)
5x-2x=28-7
3x=21
3x/3 = 21/3 (divide 3 from both sides)
x=7

Answers
Answer:
3 and 12
Step-by-step explanation:
3*5=15 and 15-3=12. The product of 3 and 12 is 36.
The integers are 3 and 12.
What is Algebra?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
let the one integer be x.
Another integer = 5x - 3
According to question,
x *(5x-3 ) =36
5x ² -3 x =36
5x² -3 x - 36 = 0
5x² -15 x +12 x - 36 =0
5x( x-3) + 12 ( x -3) =0
(5x +12)( x- 3)=0
x= -12/5 or 3
So, the integers are 3 and 12.

An investor invested a total of $2,100 in two mutual funds. One fund earned a 5% profit while the other earned a 3% profit. If the investor’s total profit was $83, how much was invested in each mutual fund?

The amount invested in the mutual fund that earned 3% was $___.
Answers
Answer:
The amount invested in the mutual fund that earned 5% was $1000.
The amount invested in the mutual fund that earned 3% was $1100.
Step-by-step explanation:
Let the amount invested in the mutual fund that was earned 5% be x and the amount invested in the mutual fund that earned 3% be y.
Statement 1: [tex]\frac{5}{100}[/tex]X+[tex]\frac{3}{100}[/tex]y = 83
Statement 2: x+y = 2100
I'll use the elimination method:
Statement 1 × 20: x+[tex]\frac{60}{100}[/tex]y = 1660
Minus Statement 1 × 20 from Statement 2: x+y-x-[tex]\frac{60}{100}[/tex]y = 2100-1660
[tex]\frac{40}{100}[/tex]y = 440
y = [tex]\frac{100}{40}[/tex]×440
= 1100
x = 2100-1100

A used bookstore sells hardback books and paperback books. A hardback book costs $11, including tax. A paperback book costs $5, including tax. Jamal bought 3 more paperback books than hardback books. Jamal spent $47. How many paperback books did Jamal buy?
Answers
Answer:
5 paperback books
Step-by-step explanation:
From the question:
A used bookstore sells hardback books and paperback books. A hardback book costs $11, including tax. A paperback book costs $5, including tax. Jamal spent $47.
Let the number of paper backs = p
Let the number rod hardbacks = h
Hence:
$11 × h + $5 × p = $47
11h + 5p = 47
Jamal bought 3 more paperback books than hardback books.
h + 3 = p
h = p - 3
How many paperback books did Jamal buy?
Hence:
11h + 5p = 47
11(p - 3) + 5p = 47
11p - 33 + 5p = 47
16p = 47 + 33
16p = 80
p = 80/16
p = 5
Hence, he bought 5 paper back books

Find all values of x in the interval [0, 2π] that satisfy the equation. (Enter your answers as a comma-separated list.)
6 sin2(x) = 3
Answers
Answer:
(15°, 165°)
Step-by-step explanation:
Given the equation 6 sin2(x) = 3, we are to find the value of x that satisfies the equation in the interval [0, 2π]
Given
6 sin2(x) = 3,
Divide both sides by 6
6 sin2(x)/6 = 3/6
sin2(x) = 1/2
2x = sin^-1(0.5)
2x = 30°
x = 30°/2
x = 15°
Since sin is positive in the second quadrant, x2 = 180-15
x = 165°
Hence the values within the interval are 15 and 165.
