Answer:
2x and 7y, because they have different variables.
Step-by-step explanation:
When we solve the equation, we will get the real answer <u>x=40</u> as a variable.
<h3>First Degree Equation</h3>
First degree equation is a mathematical sentence, which has values represented by letters.
These letters can indicate a variable or an unknown - which at the end of the equation will be the final value.
— To solve this equation, just: apply the distributive property (multiply the terms that are outside the parentheses, for the terms that are inside the symbol).
— Next, let's add the real numbers together. Next, we'll subtract the like terms before the equality, thus moving the common term after the equality by adding.
— Finally, let's divide the equation, thus obtaining the final result.
4 + 3(x + 22) = 5x - 10
4 + 3x + 66 = 5x - 10
70 + 3x = 5x - 10
3x - 5x = -10 - 70
-2x = -80
x = 80 ÷ 2
<u>x = 40</u>
Therefore, the correct value of X in this equation, will be <u>x = 40</u>.
Answer:
The slope --> m = 3
A point from the line --> ( 0 , 23 )
Step-by-step explanation:
To find the slope you put the equation y+2=3(x-7) into Slope-Intercept Form (y=mx+b)
y+2=3(x-7) --> y+2=3x-21 --> y=3x-23
m is the slope and m=3
b is the y-intercept and b is 23

Answer:
p = 497 ( to the nearest whole number)
Step-by-step explanation:
In order to do this calculation, we will apply the principle of accounting, where a certain amount is compounded periodically and yielding a future value. Compound interest is used because the percentage growth rate is added on the new amount gotten each year, and not on the first or original amount.
Hence:
FV = PV × 
where FV = future value = population in 2020 = 810
PV = present value = population in 2010 = p
r = percentage growth rate in decimal = 5% = 5/100 = 0.05
n = growth rate period per year = once = 1
t = time in years = 2010 to 2020 = 10 years
∴ 
(dividing both sides by 1.6289)
p = 810 ÷ 1.6289 = 497.2 = 497 (to the nearest whole number)
∴ population in 2010 = 497
Okay, so this is just like division. What you have to do is figure out, "If there are 36 flowers, how many vases should their be?" Study the 36 for a minute and think of a number that can be multiplied by the same number that would equal 36. (hint: it's between 2 and 7) Good luck!
