<h3>Answer: Commutative Property (choice C)</h3>
===================================================
Explanation:
Here are all of the justifications for each step
- Step 1. None needed. This is the original expression
- Step 2. Distributive property
- Step 3. Multiply (the 3 and 5 multiply to 15)
- Step 4. Commutative property. Specifically, this is the commutative property of addition which allows us to add any two numbers in any order we want. In this case, the -15 and 4x terms swap places.
- Step 5. Associative property. The parenthesis group the first two terms away from the third term.
- Step 6. Combine like terms. Both 3x and 4x have an x only so they are like terms that combine to 7x. You can think of it as 3+4 = 7, then you just tack an x onto everything to get 3x+4x = 7x.
1) x+17=20
x-10=30
2) x/4=20
x/30=2
3) 4(x+5)=40
4) x+3.2=6
5) A pizza place sells pizza for $5 per box. If I had $20 how many pizzas can I buy in all? (5x=20)
Hope this helps! Have a wonderful day.
Step-by-step explanation:
= 24 × 17 × 12
= 4,896 in³
= 12 × 10 × 4
= 480 in³
The volume of the figure
= 4,896 + 480
= 5,376 in³
A. Centrifuge had the biggest impact on the development of the cell theory
Answer:
Step-by-step explanation:
Change the inequality symbol to the symbol of equation.
Choice any two values of x and calculate the values of y:
for x = 0
for x = -2
Draw the line passing through the given points.
If is < or >, then plot the dot line.
If is ≤ or ≥, then plot the solid line.
We have the sign of an inequality ">". Therefore plot a dot line.
Now shading.
If is < or ≤, then shading to the left.
If is > or ≥, then shading to the right.
We have the sign of an inequality ">'. Therefore shading to the right.
