Answer:
The answer is choice first which is "When x = 3, both expressions have a value of 30".
Step-by-step explanation:
Given:
First expression: [tex]4(x+3)+2x[/tex]
Second expression: [tex]6(x+2)[/tex]
Through the question when we substitute x=3 into its first equation so we get:
[tex]\to 4(3+3)+2(3) \\\\ \to 4\times (6)+6\\\\ \to 24+6\\\\ \to 30[/tex]
The value will be substituted by x=3 into its second expression:
[tex]\to 6(3+2)\\\\ \to 6(5)\\\\ \to 30[/tex]
So, it will prove that both the two expressions are equivalent.

15. A hot dog stand sells of its hot dogs before noon, and of its hot dogs after noon. At the
end of the day they have 21 hot dogs left. How many hot dogs did they sell?
PLEASE HELP WILL MARK BRAINLEST!
Answer:
Step-by-step explanation:
The first thing to do is convert to a common denominator.
So 1/2 =4/8. That means the vendor sold 4/8+3/8=7/8 of its hot dogs. 280 = 7/8. Now if you divide 280 by 7, you get 1/8 (answer = 40). The vendor sold 7/8 and 1/8 was left, which = 40. 8/8 would be 280 + 40 = 320.

Answer:
The point is at about (4.5, 100).
Step-by-step explanation:
Minka's line is p = 22t, which has a y-intercept of 0.
Kenji's line is p = 50 + 11t, which has a y-intercept of 50.
Find the line with y-intercept at 0 and the line with y-intercept at 50. Follow the two lines until they intersect. The point of intersection is about (4.5, 100).
You can find this point by setting the two equations equal to each other:
22t = 50 + 11t
Subtract 11t from both sides.
11t = 50
t = 50/11 ≈ 4.545
Then you can find the p value for this point by plugging t = 4.545 into either equation.
p = 22(4.545) = 99.99
p = 50 + 11(4.545) = 99.995
On the graph the point is about (4.5, 100).
Identify two segments that are marked congruent to each other on the diagram below. ANSWER CORRECTLY !!!!!!!!!!! WILL MARK BRIANLIEST !!!!!!!!!!!! (Two capital letters each )
We have a parallelogram, and we want to identify two segments that are parallel. then LO is parallel to MN.
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
Here We can see that ON is parallel to LM and LO is parallel to MN
Because this is a parallelogram as we know this because there is a 90° angle at N, the opposite sides are parallel.
So from this, we can conclude that sides ON and LM are opposite, then ON is parallel to LM
With the same reasoning, LO is parallel to MN.

Find the measure of the listed angles below.
Answer:
30,90
Step-by-step explanation:
because it all adds up to 180
Answer:
E and I are alternate interior angles, therefore are congruent
m∠E = m∠I = 60°E and F are complementary, therefore add to 90°
m∠F = 90° - 60° = 30°H and I supplementary, therefore add to 180°
m∠H = 180° - 60° = 120°The price of a hot tub was marked down by $250. The original price of the hot tub was $3,600. What was the percentage rate of the discount (to the nearest

If I cut a cake into equal parts and one slice = 3.333, where would I find the 0.001? (total of slices = 10)
Step-by-step explanation:
That is so because 1/3 is *not exactly equal to* 0.333333
0.333333 is an approximation of 1/3 which is correct to 6 decimal places.
So 0.333333 x 3 = 0.999999 which is approximately equal to 1.
If you want to be more accurate, you could write the fraction 1/3 everywhere and not write it in floating point form.
1/3 in floating point format will be 0.333333333…..and so on with infinite decimal places. This is because when you try to divide 1 by 3, you get a nonterminating recurring number after decimal point.
Its usually represented by a bar or dot on top of the recurring part
Ex. 1/3 = 0.3bar
(Sorry I can't get the bar on 3 by typing from keyboard)
But let's just say 0.3 bar is 0.333333…and so on to infinity.
When you multiply 0.3bar x 3 you get 0.9bar
= 0.999999….and so on to infinity.
These decimal point figures just a very great approximations of the fraction 1/3.

In 2010, Cornfield Farms produced 175,000 bushels of corn. Each year since 2010, their total corn harvest has increased by 2.5% over the previous year.
Write an exponential function, f(x), that models the number of bushels of corn produced x years after 2010.
Enter your answer by filling in the boxes.
f(x)= · ( )x
Answer:
f(x)=(2.5)x
Step-by-step explanation:
x equals the number of years after 2010, and every year after 2010 their total corn harvest increases by 2.5%, so you would have 2.5 multiplied by however many years after 2010 it is
The exponential function f(x) that models the number of bushels of corn produced x years after 2010 is f(x) = 175000(1.025)^x
How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:
[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]
The final amount becomes:
[tex]A = CI + P\\A = P(1 +\dfrac{R}{100})^T[/tex]
We can use compound interest formula whenever there is compounding (increment or decrement) per unit time.
Here, the initial amount of production farm was doing in 2010 is 175000 bushels of corn.
This value increases by 2.5% per year.
We need the final number of bushels of corn that will be produce x years after 2010.
So, here, we can take P = 175000, R = 2.5, and T = x
Then, we get:
[tex]f(x) = A = 175000\left(1 + \dfrac{2.5}{100}\right)^x\\\\f(x) = 175000(1.025)^x[/tex]
Thus, the exponential function f(x) that models the number of bushels of corn produced x years after 2010 is [tex]f(x) = 175000(1.025)^x[/tex]
