Here is the example.
Multi-step equation means before start solving equations, you need to isolate the variable terms and constant terms, then you have to combine the like terms.
Finally, you can solve the equation. This involves more than two steps.
Examples:
1) 2x + 3x + 5 = 20
Step 1: Isolate the variable terms and constants.
Subtract 5 on both sides, we get
2x + 3x + 5 - 5 = 20 -5
2x + 3x = 15
Step 2: Combine the like terms.
5x = 15
Step 3: Divide both sides by 5.
5x/5 = 15/5
x = 3.
2) 2(3x + 2) = 3(x - 1) + 4
Step 1: Use the distributive property and expand the given equation.
6x + 4 = 3x -3 + 4
Step 2: Isolate the variable terms and constants
Subtract 3x from both sides, we get
6x - 3x + 4 = 3x - 3x -3 + 4
3x + 4 = -3 + 4
Step 3: Simplify it.
3x + 4 = 1
Step 4: Subtract 4 from both sides.
3x + 4 - 4 = 1 - 4
3x = -3
Step 5: Divide both sides by 3.
3x/3 = -3/3
x = -1.
Hope this will help you. :)
Option B and D would have closed circles when graphed
The domain and range of a function are the components of a function. The domain is the set of all the input values of a function and range is the possible output given by the function.
At the endpoints of the domain, we draw open circles to indicate where the endpoint is not included because of a less-than or greater-than inequality; we draw a closed circle where the endpoint is included because of a less-than-or-equal-to or greater-than-or-equal-to inequality.
∴ Option B and D that are 5.7 ≤ p and ≥ y respectively would have closed circles

Answer:
D does not show an equivalent rate
Step-by-step explanation:
we first need to find out how many words typed per minute so we divide 75 by 3 (3 divided by 3 is 1 and what we do to one side must be done to the other)
75 ÷ 3 = 25
25 word per 1 minute
now we need to multiply the minute by 25 to get the number of words typed
25(words) x 1(minute) = 25 words in 1 minute(so A is correct)
25(words) x 2(minute) = 50 words in 2 minutes(so B is correct)
25(words) x 4(minute) = 100 words in 4 minutes (so C is correct)
25(words) x 5(minute) = 125 words in 5 minutes(so D is incorrect)
Answer:
10 year old
Step-by-step explanation:
because the 10 year old has a better developed body than a 5 year old.
Hope this helps, have a nice day/night! :D
Answer:
24
Step-by-step explanation:
Use the Pythagorean theorem.
Where the sum of the two legs squared is equal to the hypotenuse squared.
10² + x² = 26²
100 + x² = 676
x² = 576
x = √576
x = 24
The value of x is 24.
