Juan wants to solve the equation below using the Distributive Property.
4(6 – x) = 12
What should Juan’s first step be?
A. Multiply 4 by x.
B. Subtract x from 6.
C. Distribute 4 to (6 – x).
D. Subtract 4 from both sides.
Answer:
C. Distribute 4 to (6 - x).
Step-by-step explanation:
Person above is right.
Juan’s first step should be C. Distribute 4 to (6 – x).
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
a(b + c) = a b + a c
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
We are given an equation as;
4(6 – x) = 12
Here Juan wants to solve the equation, using the Distributive Property.
thus, 4(6 – x) = 12
First step is to distribute 4.
4(6) – 4(x) = 12
Then solve;
24 - 4x = 12
x = 3
Hence, Juan’s first step should be C. Distribute 4 to (6 – x).

Step-by-step explanation:
Step 1: Define Equation
3(4x - 5) - 4x + 1 = -6
Step 2: Solve for x
Distribute 3: 12x - 15 - 4x + 1 = -6Combine like terms: 8x - 14 = -6Isolate x term: 8x = 8Isolate x: x = 1Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(4(1) - 5) - 4(1) + 1 = -6Multiply: 3(4 - 5) - 4 + 1 = -6Subtract: 3(-1) - 4 + 1 = -6Multiply: -3 - 4 + 1 = -6Subtract: -7 + 1 = -6Add: -6 = -6Here we see that -6 does indeed equal -6.
∴ x = 1 is the solution to the equation.

Sandy has 27 roses, 9 daisies, and 18 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?
Answer:
The greatest number of flowers that could be in a bouquet is 9 flowers
Step-by-step explanation:
We solve the above question using Greatest Common Factor method. We find the factors of 27, 9 and 18. The greatest factor common to the 3 number is our answer.
The factors of 9 are: 1, 3, 9
The factors of 18 are: 1, 2, 3, 6, 9, 18
The factors of 27 are: 1, 3, 9, 27
Then the greatest common factor is 9.
The greatest number of flowers that could be in a bouquet is 9 flowers

(5,6) and (−5,12) what is the rate of change??
Answer:
- 0.6
Step-by-step explanation:
Start point: (5,6)
End point: (-5,12)
rate of change = (12-6) / (-5-5) = 6/-10 = - 3/5 = - 0.6
Answer:
The rate of change is -0.6
Step-by-step explanation:
Given
[tex](x_1,y_1) = (5,6)[/tex]
[tex](x_2,y_2) = (-5,12)[/tex]
Required
Determine the rate of change
The rate of change means the slope (m) and it is calculated as thus:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{12-6}{-5-5}[/tex]
[tex]m = \frac{6}{-10}[/tex]
[tex]m = -\frac{6}{10}[/tex]
Simplify the fraction
[tex]m = -\frac{3}{5}[/tex]
[tex]m=-0.6[/tex]
The rate of change is -0.6

22+15x=34-17x
Step-by-step explanation:
22+15x=34-17x
So now, the 34 will join the 22 and the 15x will join the -17x
22-34=-17x-15x
-12=-2x
So now, we divide both sides by -2x
and the negative will cancel negative so

Find the value of n.
Answer:
20cm
Step-by-step explanation:
Answer:
n = 15
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = n + 1 and h = n + 1 - 5 = n - 4 , then
[tex]\frac{1}{2}[/tex](n + 1)(n - 4) = 88 ( multiply both sides by 2 to clear the fraction )
(n + 1)(n - 4) = 176 ← expand the left side using FOIL
n² - 3n - 4 = 176 ( subtract 176 from both sides )
n² - 3n - 180 = 0 ← in standard form
(n - 15)(n + 12) = 0 ← in factored form
Equate each factor to zero and solve for n
n - 15 = 0 ⇒ n = 15
n + 12 = 0 ⇒ n = - 12
However, n > 0 , thus value of n = 15

Why is the percent increase from 45 to 75 not equal to the percent decrease from 75 to 45? Select three options.
UThe amount of change drent for the percent increase and the percent decrease
UThe ratio of the percent increase is not the same as the percent decrease.
OThe ratio for the percent increase has a smaller denominator than the percent decrease.
U The ratio for the percent increase has a different numerator than the percent decrease.
O The original amount for the percent increase is different from the original amount for the percent decrease.
Answer:
work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.

__________
x = 44 - 39
x = 5........eq 1
Now putting the values in any equation
4 ( 5 ) + 3 y = 44
20 + 3 y = 44
