1:What is the value of x
2:what is the measure of angle KJL?
Hurry pls WILL GIVE BRAINLEST
Answer: x=6
Step-by-step explanation:
Those two angles are supplementary, so added together, they will equal 180.
That being said,
23x+3+6x+3=180
29x+6=180
29x=174
x=6
is the equation. By solving that, you get
x=6
help me you dont have to do all of them but if you do pls i will give you the brainiest

Answer:
R=51
Step-by-step explanation:
6x-9+7x=121
add like terms:6x+7x=13x
13x-9=121
to cancel out (-9) and to isolate x, add on both sides
13x=130
divide into both sides
x=10
to solve for angle Rsubstitute 10 for x
6(10)-9
R=51

What will be the result of substituting 2 for x in both expressions below?
1/2 x + 4
x + 6 - 1/2 x minus 2
Both expressions equal 5 when substituting 2 for x because the expressions are equivalent.
Both expressions equal 6 when substituting 2 for x because the expressions are equivalent.
One expression equals 5 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.
One expression equals 6 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.
Answer:pretty sure the answer is A
Step-by-step explanation:
1/2(2) + 4 = 1 + 4 = 5
2 + 6 - 1/2(2) -2 = 8 - 1 - 2 = 5

The tail of a kite is 1.5 feet plus twice the length of the kite. Together, the kite and tail are 15.5 ft long. Find the length of the tail.
What is the length of the tail? Show your work.
Answer:
We know that the kite with the tail is 15 feet and 6 inches. While 6 inches is 0,50 foot, it's 15,5 feet. If the lenght of the kite is x, then:
15,5 = x + 1,5 + 2x
15,5 = 3x + 1,5 / - 1,5 (both sides)
14 = 3x / : 3 (both sides)
x ≈ 4,66
The kite is approx .4,66 feet long. It means that the tail is about 15,5 - 4,66 = 10,84 feet long.
Answer:
10 5/6 feet
Step-by-step explanation:
Tail= 1.5+2Kite
Kite+Tail=15.5
x+1.5+2x=15.5
3x=15.5-1.5
3x=14
x=14/3=4 2/3
Kite=4 2/3
Tail= 1.5+2(4 2/3)=10 5/6

7. Jon's car averages 20 mpg in town and 28 mpg on the road. What is the percent of decrease between the two driving conditions?
Answers:
1)10.80/12 =0.90
0.90+0.75=1.65
2)252/7=36 units
3)cost price = $9.25*225
= $2081.25
Selling price = $15.75*225
= $3543.75
Profit = Selling price - cost price
Profit = $3543.75 - $2081.25
=$1462.50
5) FV = L*(1 + rt),
Where FV is the amount to repay; L is the borrowed amount (the loan amount) and "r" is the annual interest as decimal; t is the time.
In your case L = 2400 dollars; r = 8% = 0.08 (as decimal) and t = 0.5 of a year (6 months).
Therefore,
FV = 2400*(1 + 0.08*0.5) = 2496.
In 6 months, Della Rilley must repay $2496

C. Substitute the result from the previous step into x=3y−1 and solve for the unknown variable.
D. Write the solution as an ordered pair. E. Check the solution with the equation not used in Step C.
Answer: X=29
Step-by-step explanation:
First you substitute the x's: 2(3y-1)-5y=8
Then you open parenthesis:6y-2-5y=8
Combine like terms: y-2=8
Bring the 2 to the other side: y=10
Now you substitute the y with the answer: x=30-1
Easy equation: x=29

The number of kilograms that an object weighs varies directly as the number of pounds. If an object weighs 45 kilograms or about 100 pounds, about how many kilograms is an object that weighs 70 pounds?
Answer:
This is the specific answer: 31.7515
Answer: 31.5
Step-by-step explanation:
To solve this ratio problem, you need the common ratio. Divide the amount of pounds by the amount of kilograms.
Step 1: Divide 100 pounds by 45 kilograms
100 ÷ 45 = 2.2
This is the common ratio
Step 2: Divide 70 pounds by 2.2
70 ÷ 2.2 = 31.5
This is the amount of kilograms in a 70 pound object

A jar contains only pennies, nickels, dimes, and quarters. There are 29 pennies, 13 dimes, and 21 quarters. The rest of the coins are nickels. There are 91 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
Answer:
First Question: 63 coins are not nickels.
Second Question: 63+n=91
Step-by-step explanation:
For your first question: 29+21=50 and 50+13=63. 63 coins are not nickels.
For your second question: You can do 29+21+13+n=91, I just simplified and said 63+n=91. You can choose.
Hope that this helps! Good luck with what you're working on!
Answer:
63 coins are not nickels.
Equation to find n:
91 - 63
Or
91 - n

3^10
3^12
Answer:
3^12
Step-by-step explanation:
(3^5)^2 / 3 − ^2 = 243^2/3−^2 = 59049 / 3−^2 = 59049/ 1 / 9 = 531441
= 3*3*3*3*3*3*3*3*3*3*3*3 = 3^12

b. yes. y = 24x
c. y = 24x
Step-by-step explanation:
6. There are 6 muffins per pack, and that stays consistent. Because it is constant, you can model this with the equation m=6p or y = 6x. 6 times the number of packs = the number of muffins.
7.
a. There are 24 hours in a day. Days = x, hours = y. 24 hours times the number of days = the total numbers of hours. I just built a table based off of that.
b. there are consistently 24 hours in a day, every day so it is constant.
c. 24 hours per day. total hours = 24 (number of days)

From 11:15 to 11:30 AM, a whale’s elevation changed from –80 meters to –101 meters. If the whale’s elevation is changing at a constant rate, what time was the whale’s elevation –94 meters?
The time was 11:25 the whale’s elevation is 94 meters because 15 minutes elapse between 11:15 and 11:30.
What is the rate?A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.
As per the given question,
From 11:15 to 11:30 AM, a whale’s elevation changed from –80 meters to –101 meters.
The whale climbed 21 feet in 15 minutes. The unit rate is 1.4 meters per minute.
There are 14 meters between -80 and -94. The whale will take 10 minutes to reach -94m at a speed of 1.4m/min. The whale began at -80 at 11:15, and 10 minutes later it is 11:25.
Thus, the time was 11:25 the whale’s elevation is 94 meters because 15 minutes elapse between 11:15 and 11:30.
