Answer:
This is a complete lesson with instruction & exercises for 5th grade about multiplying decimals by decimals. The interpretation for multiplying a decimal by a decimal is to think of it as taking a fractional part of a decimal number (the symbol × translates to "of"). The lesson compares multiplication by a decimal to scaling & shrinking a stick. Lastly, it shows the common shortcut to decimal multiplication (multiply as if there were no decimal points; the answer has as many decimals as the factors have in total.)
In the video below, I explain the rule for multiplying decimals (put as many decimal digits in the answer as there are in the factors.) I explain where this rule comes from, using fraction multiplication. The lesson continues below the video.

4. Find CD and X . (3 points) x ^ 3 + 20 30 D x ^ 8 + 22x - 120 will mark brainliest
Answer:
CD = 15
x = 5
Step-by-step explanation:
Since BF ≅ FD and AE ≅ EC, then [tex]EF = \frac{AB + CD}{2}[/tex]
So, [tex]30 = \frac{x^{2} +20 + x^{2} + 22x - 120}{2}[/tex]
[tex]60 = 2x^{2} + 22x - 100[/tex]
[tex]2x^{2} + 22x - 160 = 0[/tex]
[tex]2(x^{2} + 11x - 80) = 0[/tex]
2(x - 5)(x + 16) = 0
x = 5 or x = -16
If x = 5, then CD = [tex]5^{2} +22(5) - 120 = 25 + 110 - 120 = 15[/tex]
Ix x = -16, then CD = will be a negative number which it cannot be.

Answer:
The area of a rectangle is l x w. So the area of the square is 10 x 10 = 100
The area of a circle is
[tex]\pi \times {r}^{2} [/tex]
The radius of all the circles is 2 inches.
[tex]\pi \times {2}^{2} = \pi \times 4 \: or \: 4\pi[/tex]
There are 4 circles so the area of all four is
[tex]4 \times (4\pi) \: or \: 16\pi[/tex]
To find the area of the shaded part of the square, subtract the area of all the circles, because they are not shaded, from the area of the square, because it is shaded. The difference will be the area of the shaded portion.
[tex]area \: = 100 - 16\pi[/tex]
[tex]area = 100 - 50.6548[/tex]
So the area is approximately 50 Sq in

Answer:
y = (-x/3) +1 or y = (-1/3 * x) + 1
Step-by-step explanation:
For the inverse of a function, you invert the y and x positions.
In your case:
y = -3x+3
The inverted function is:
x = -3y+3
When you solve this for y, you get:
-3y = x-3
y = -x/3 +1
Solve:
3 + 2 + 52 × 6 − 3 =
(3 + 2) + 52 × (6 − 3) =

The product of 3 and
increased by 5
Answer AND expaination
The product of a number and 3 increased by 5 is 7 less than twice the number which equation can be used to find this number , n?
its -7
the product of a number and 3: 3n
increased by 5: + 5
7 less than: - 7
twice the number: 2n
That gives us the following:
3n + 5 = 2n - 7
You only asked for the equation, not to actually help you solve for n, for note. If you do, just subtract 2n from both sides, and then subtract 5 from both sides.

Sarah works for a maximum of 40 hours per week. She needs to make at least $400 in order to cover her expenses. Her office job pays
$12 per hour and her babysitting job pays $10 per hour.
Which system of inequalities can be used to determine the number of hours she should spend working in office (x) and the number of
hours she should spend babysitting (/) to cover her expenses?
Answer:
x + y ≤ 40
10x + 12 y ≥ 400
x ≥ 0
y ≥ 0
Step-by-step explanation:
System of Inequalities
In order to model the situation stated in the problem, we'll call the following variables:
x = number of hours Sarah spends in the office
y = number of hours Sarah spends babysitting
She works for a maximum of 40 hours per week. This condition leads us to the inequality:
x + y ≤ 40
Her office job pays $12 per hour and her babysitting job pays $10 per hour.
She needs to make at least $400 per week in order to cover her expenses, thus:
10x + 12 y ≥ 400
Two obvious conditions could be added to the set of inequalities:
x ≥ 0
y ≥ 0
The system of inequalities is:
x + y ≤ 40
10x + 12 y ≥ 400
x ≥ 0
y ≥ 0
