Answer:
12 + 2x
Step-by-step explanation:
2(10) + 2(x - 4)
20 + 2(x - 4)
20 + 2x - 8
12 + 2x
Answer:
-6
Step-by-step explanation:
2(10)+2(x-4)=0
20+2x-8=0
20-8+2x=0
12+2x=0
2x=-12
x=-6
Solve: 5(3x + 2) -2 = 2 (1 -7x)
Answer:
x=-6/29
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(3x+2)−2=2(1−7x)
(5)(3x)+(5)(2)+−2=(2)(1)+(2)(−7x)(Distribute)
15x+10+−2=2+−14x
(15x)+(10+−2)=−14x+2(Combine Like Terms)
15x+8=−14x+2
15x+8=−14x+2
Step 2: Add 14x to both sides.
15x+8+14x=−14x+2+14x
29x+8=2
Step 3: Subtract 8 from both sides.
29x+8−8=2−8
29x=−6
Step 4: Divide both sides by 29.
29x/29=-6/29
x=-6/29

A triangle’s base is 3 feet longer than twice its height, h. To create a new triangle, the base is decreased by 4 feet, and the height is increased by 2 feet. Which expression represents the area of the new triangle?
Answer:
area of the triangle =
[tex] \frac{(x - 4) \times (y + 2)}{2} [/tex]
let base be x and height y

PLS mark BRAINLIEST
Answer:
let height be x
base =2x+3
for new
height =x+2
base=2x+3-4=2x-1
area of new triangle=1/2_newbase×height

=============================================================
Explanation:
First we'll focus on triangle DEH. Ignore the other points and values.
We have the sides of EH = 32 and DH = 49. Let x be the measure of angle DHE, which is one of the pieces of angle DHG. We'll use the cosine rule to find x.
cos(angle) = adjacent/hypotenuse
cos(H) = EH/DH
cos(x) = 32/49
x = arccos(32/49)
x = 49.227195
The value is approximate and rounded to 6 decimal places. Make sure your calculator is in degree mode. Arccos is the same as inverse cosine.
We'll come back to this value later.
---------------------
Now focus on triangle HFG. Ignore the other points.
We have the sides of FG = 38 and GH = 43
Let y be the measure of angle FHG, which is the missing piece to form angle DHG. Based on how x and y are set up, we can say x+y = angle DHG.
To find y, we'll need the sine rule this time
sin(angle) = opposite/hypotenuse
sin(H) = FG/GH
sin(y) = 38/43
y = arcsin(38/43)
y = 62.094527 which is approximate to 6 decimal places
---------------------
The last step is to add the values of x and y we found earlier
angle DHG = (angle DHE) + (angle FHG)
angle DHG = (x) + (y)
angle DHG = (49.227195) + (62.094527)
angle DHG = 111.321722
angle DHG = 111 degrees after rounding to the nearest whole degree.
----------------------
If you wanted to do this all in one step, you could say:
arccos(32/49)+arcsin(38/43) = 111.3217 which rounds to 111 degrees.
158.297 rounded each number to the nearest while number
Answer:
158.3

A. The differance between the slowest and the fastest 25-yard times was 5.842.
B. The teams total 100-yard relay time was 55.079 sec.
C. The last two swimmers took a total of 27.842
D. The second swimmer was 2.127 sec fasterbthen the third swimmer
Answer:
C.
Step-by-step explanation:
A. The difference between the slowest and fastest is 4.238 secs
B. The team total is 55.115 secs
C. The last two swimmers took a total of 27.842 (correct)
D. The second swimmer was faster than the third by 1.767 secs
1. Solve the following linear equation and state the value/s of x. Round to the
nearest tenth if necessary.
2(x - 5) + 4 = 2(x-3)
Answer:
No Solution
Step-by-step explanation:
2(x - 5) = 2(x - 3)
2x -10 = 2x -6 When we subtract 2x from both sides we are left with a false statement.

Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125. Estimate the number of months that Zea can continue this pattern until she reaches her credit limit.
The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.
What is a credit card?A credit card is a method of payment that is given to customers so they may pay a merchant for products and services depending on the debt they have accumulated.
Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125.
The distinction between the installment made and the charges done will be given as,
Difference = $200 - $125
Difference = $75
Partition as far as possible by this distinction to find the number of months that Zea can proceed with this example until she contacts her credit limit.
⇒ $2,000 / $75
⇒ 26.667 ≈ 27
The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.

A wedding reception was
being held at Stefano's
restaurant. They charged
$2.00 per person for
appetizers, $20.00 per
person for the main course
and $250 for the wedding
cake. There were 50 people
at the reception. What was
the total cost of the
reception?
Answer:
the total cost of the wedding would be: 1,350
Step-by-step explanation:
2×50=100 and 20×50=1,000
100+1,000=1,100
1,100+ 250= 1,350
total for wedding is 1,350
:)
Answer: The answer for this problem is $1350.
Step-by-step explanation:
The first thing you do is to see how much money for the appetizers and the main course did all 50 people pay.
50 x 2 = 100, how much money in total for the appetizers
50 x 20 = 1000, how much money in total for the main course
Once you're done with that! Next, you add the total prices for the appetizers and the wedding cake. Then, you add up the $250, so you get your answer!
$100 + $1000 = $1100
$1100 + $250 = $1350
This is how you get the answer!
