When solving an equation, Drew's first step is shown below. Which property justifies Drew's first step?
Original Equation: 5(x + -5) = 4
First Step: 5x+−25= 4
1. addition property of equality
2.division property of equality
3.associative property of multiplication
4.distributive property of multiplication over addition
Answer:
Step-by-step explanation:
4 is the right answer
First step shows the "Distributive property of multiplication over addition"
What is distributive property of multiplication over addition ?
If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.
Here the equation given is : 5(x+-5) = 4 ,
and, the first step is 5x=-25 = 4
which is obtained by the distributive property of multiplication over addition where, 5 is being multiplied with x and -5 respectively.
Therefore, Distributive property of multiplication over addition is the answer.

Which of the following is equal to 4 2/3 / 3 1/2?(If you think its the answer I picked in the picture, its not) Thank you so much for you help!!
Answer:
b
Step-by-step explanation:
4 2/3= 12/3+2/3=14/3
3 2/1=7/2 but you have to flip it
so you end up with 14/3*2/7
4 2/3 = 14 / 3
3 1/2 = 7/2
An easy way to divide fractions is to find the reciprocal of the second fraction.
The reciprocal of 7/2 = 2/7
Then we multiply straight across.
14/3 × 2/7

Angela wants to purchase carpeting for her living room. The dimensions of her living room are 15 feet by 18 feet. If carpeting is sold by the square yard, determine how many square yards of carpeting she must purchase.
Answer: 15 square yards of carpeting.
Hope this helps!
Pretty sure i'm wrong on this one but I can't figure it out either.
Sorry if I wasted your time.
Angela must purchase 29.7 square yards of carpeting.
How to Convert Square Feet to Square yards?Multiply the area by the conversion ratio to convert a square foot measurement to a square yard measurement. Because one square foot equals 0.11 square yards, you may use the following easy formula to convert:
square inches = square feet × 0.11
The area in square inches is equal to the square feet multiplied by 0.11.
The dimensions of her living room are 15 feet by 18 feet.
The area in square feet is :
15 × 18 = 270 sq ft
Now, the area in square yards is :
270 × 0.11 = 29.7 sq yds
Thus, she must purchase 29.7 square yards of carpeting.

Answer:
γ = [tex]\lim_{n \to \infty}\sum_{k=1}^n (\frac{1}{k}-ln(n) )[/tex]
or
γ = -∞
Step-by-step explanation:
Let's solve what's inside the limit first.
We see that we need to take the sum of the entire thing. Since it is multivariable and we are given 1 variable, it stays the same.
Now we move on to the limit.
We replace n in the summative with infinity.
The natural log of infinity is infinity.
1 minus infinity would be negative infinity.
The sum of negative infinity of k = 1 is negative infinity.
So the limit as n approaches infinity would be negative infinity.
If we were to simplify this mathematically, it would just be the same equation.
