Answer: 24
Step-by-step explanation:
Chocolate bars sold in first week:
= 2x² + 3x − 1
where x = 2
= 2x² + 3x − 1
= 2(2)² + 3(2) − 1
= (2×4) + 6 - 1
= 8 + 6 - 1
= 13
Second week
= 3x² - 2x + 3
= 3x² - 2x + 3
= 3(2)² - 2(2) + 3
= 12 - 4 + 3
= 11
Total chocolate sold = 13 + 11 = 24

(2x + 29) + 91 = 180.
This is because they add to form a straight line which is 180 degrees, in other words the angles are supplementary.
2x + 29 = 89 (Subtract 91 from each side)
2x = 60 (Subtract 29 from each side)
x = 30 (Divide 2 from each side)
x = 30
The answer is B

Answer:
x = 21
Step-by-step explanation:
By the corresponding angle theorem, we can find that the measure of the smaller angle made by transversal and m is 54°.
Using the vertical angle theorem, we can find that the missing angle is the triangle, the two known angles are 4x and 2x, is also 54°.
Since the sum of the interior angles of a triangle is always equal to 180°, we can make the equation:
2x + 4x + 54 = 180
Now we solve for x. Subtract 54 from both sides and combine like terms.
6x = 126
Divide both sides by 6.
x = 21
and now we have found the value of x. x = 21.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
x=21°
Step-by-step explanation:
Relations Between Angles
We need to recall two basic relations:
* Two angles opposite by crossing lines are always equal.
* The sum of angles in a triangle is 180°
We'll add some variables to the image, so x is easier found. Please check the image below.
The angles U and 54° are opposite and they must be equal, thus U=54°
Since m and n are parallel and they are crossed by a line, the angles V and U are equal, thus V=54°
Finally, The sum of the angles inside the triangle RST must be equal to 180°:
2x+4x+54=180
Joining like terms:
6x=180-54=126
Solving:
x=126/6
x=21°
Trent told his friends it would take him 90 minutes to mow the lawn. It only took him
75 minutes. What is his percent error?
Answer:
The answer is 16%
Step-by-step explanation:
use the percent error formula.
[tex]\frac{|E-T|}{|T|} *100[/tex]
in this problem,
e= 75
t=90
substitute and solve.
[tex]\frac{|75-90|}{|90|} *100\\\frac{|-15|}{|90|}*100\\\\ .16667*100\\[/tex]
16%
we are dealing with percents so rounding to nearest whole number will suffice.

3(n+5)≥3n+8. help, please
Answer:
so you distrubute the 3 into the parenthesis and you then get 3n+15 is greater than or equal to 3n+8 then you subtract the 3n from the right side from the 3n on the left side and you are left with 15 is greater than or equal to 8

Which steps show how to use the distributive property to evaluate 6.49?
O A. 6(49) = 6(50 – 1) = 6.50 +6.1 = 300 + 6 = 306
O B. 6(49) = 6(50 – 1) = 6 - 50 – 6.1 = 300 – 6 = 294
C. 6(49) = 6(50 – 1) = 6 - 50 – 50 · 1 = 300 – 50 = 250
O D. 6(49) = 6(50 – 1) = 6.50 – 1 = 300 – 1= 299
Answer:
Correct Choice: B. 294
Step-by-step explanation:
The distributive property allows modifying expressions in the form of a(b + c) into the form ab+bc.
If we wanted to express the product 6*49 as 6*(50-1), then applying the distributive property we have:
6*(50-1)=6*50-6*1
6*(50-1)=300-6
6*(50-1)=294
Correct Choice: B. 294
Answer:
Answer is B = 294

2(5+t)=8
Step-by-step explanation:
2×5+2t=8
10+2t=8
collect like terms
10-8=2t
2 =2t
divide both sides by 2
2 = 2t
2/2 =2t/2
1 = t
t = 1

I need it fast, I'm timed
Answer:
It is B
Step-by-step explanation:
Plug each value possible into the equation
(48+x) / 31 = x/15
If both sides are equal when you plug x in, it's correct
If they aren't equal, it is wrong.
How did I get this equation?
Lets use proportions to solve.
Since they are similar, (the two triangles are similar, meaning that they have the same ratio of the y and x axis values) you can use proportions meaning you make it so x over 15 is equal to the total length by the total bottom length.
If you plug 45 in as x, you get (48 + 45) divided by 31 is equal to 45/15
If you simplify the equation, you get 93 divided by 31 is equal to 3, of which 93 divided by 31 is 3
I think you know that 3=3
so it is correct.
