If he used 3 gallons of gas. Then the amount of the gas in the tank after driving for 2 hours will be 9 gallons.
What is Algebra?Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.
Mason is driving on a long road trip. He currently has 12 gallons of gas in his car. Each hour that he drives, his car uses up 1.5 gallons of gas.
Then the amount of the gas in the tank after driving for 2 hours will be
The amount of gas used in 2 hours will be
Used gas = 2 x 1.5
Used gas = 3 gallons of gas
Then the remaining amount will be
Remaining amount of gas = 12 - 3
Remaining amount of gas = 9 gallons

Answer:
#5. m<NMO = 44 and X = 9
Step-by-step explanation:
#5. 5x - 1 + 3x + 4 = 75 (<NMP is the entire angle, which equals 75.)
combine like terms
8x + 3 = 75
subtract 3 from both sides and divide 8.
x = 9
5(9) - 1
m<NMO = 44

A piano has a length of 8 feet and a width of x+2 feet, write an expression in simplest form of the perimeter of the piano.
Answer: 2(x + 10)
Step-by-step explanation: you have to add all of the perimeter sides together so you will have to times the length by 2 so your equation would be (8 × 2 = 16). Then the width by 2 ( 2 × (x+2) = 2x + 4) now you add them together
16 + 2x + 4
2x + 20
Now you have to take out the highest common factor which is 2
So it will be 2(x + 10)

x = 9.47 degrees ( in first quadrant.
Step-by-step explanation:
sin2x + sinx cos x = 1/2
Now sinx cos x = 1/2sin2x so:
3/2sin2x = 1/2
sin2x = 1/2 / 3/2
sin2x = 1/2 * 2/3 = 1/3
2x = arcsin 1/3 = 19.47 degrees
x = 9.74 degrees to nearest hundredth.

On a morning in December, Carl wakes up and checks the thermometer. He reads that it is -10°F. In two hours he checks and the temperature has risen 4°F. In another three hours the temperature has risen 7°F. At the last time, he checks the thermometer, what is the temperature? Also writes an addition equation that models this situation
Answer: 1 degree Fahrenheit
Step-by-step explanation:
The temperature starts at -10 degrees F, so if in two hours, the temperature has risen by 4 degrees, then the new temperature is -10 + 4 = -6 degrees F. 3 hours later, the temperature has risen another 7 degrees, so the new temperature is -6 + 7 = 1 degrees F. "addition equation" is ambiguous without knowing what class you are taking, but one such equation to represent the situation could be T = -10 + 4 + 7 = 1.
Use the figure below to answer the question
Solve for x
Answer:
Step-by-step explanation:
The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides. The problem concerns a polygon with six sides, so we will let n = 6. The sum of the interior angles in this polygon would be 180(6 – 2) = 180(4) = 720. The angle on the bottom left is a right angle because of the square indicator. We know that this is 90 degrees. If we take the sum of the angles that we know we get 593. 720 - 593 = 127. x = 127.
Answer:
x=127
Step-by-step explanation:
take 180(n-2) where n=6, and you get 180(6-2) which simplified is 180(4) = 720. The sum of all the other angles is 593. subtract 593 from 720 (720-593=127). 127 is the angle of x.
all the steps laid out:
1. 180(n-2)
2. n=6
3. 180(6-2)
4. 180(4) = 720
5. 126 + 112 + 155 + 110 + 90 = 593
6. 720 - 593 = 127
7. x=127

Francine and Cheryl received equal scores on a test made up of multiple choice questions and an essay. Francine got 34 multiple choice questions correct and received 14 points for her essay. Cheryl got 30 multiple choice questions correct and received 22 points for her essay.
How many points was each multiple choice question worth?
Enter your answer in the box.
Answer:
Francine's score: 34x + 14
Cheryl's score: 30x + 22
Equal scores => 34x + 14 = 30x + 22
34x - 30x = 22 - 14
4x = 8
x = 8 /4 = 2.
Answer: 2
Step-by-step explanation:
Select all of the points which satisfy the linear inequality below.
-2x + 3y > 4
Answer:
x < − 2 + 3 y/ 2 linear inequality for x
y > 4/3 + 2x/3 linear inequality for y
Step-by-step explanation:
The point which satisfies the linear inequality is (-1,5) so option (C) is correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given inequality,
-2x + 3y > 4
Put (-1,5) into the above inequality,
-2(-1) + 3(5) > 4
2 + 15 > 4
17 > 4 (True) thus (-1,5) will satisfy the inequality.
The rest points are not satisfying the inequality.
Hence " The point which satisfies the linear inequality is (-1,5)".

Jeanette earn $33 in 8 hours. At the rate, how much would she earn in 5 hours?
Answer:
If you made $33 in 8 hours, then you should divide 8 into 33 to see how much you make per hour. 8÷33= (explaining how to get answer) can 8 go into 3? No. put a zero on top of the first three. Now can 8 go into 33? yes, 4 times, 4×8= 32, so we have 1 left over. add 2 decimals to the number so that it is $33.00, (still that same number just with zeros on the end). So far the answer is $04.??. How many times can 8 go into 10? 1 time with 2 left over, so write the one on top of the .0! Now with 2 left over we have to see how many times 8 can go into 20, 8×2= 16 16+8=24, so it can only go in 2 times without going over 20. Now that we have rounded it up to 2 decimals we don't have to keep going and your answer is
$4.12 times that by 5 and you will get the final answer.
