4x 10
12x + 151
S
Answer:
x = 10
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
12x + 15 is an exterior angle of the triangle , then
12x + 15 = 4x + 10 + 85 , that is
12x + 15 = 4x + 95 ( subtract 4x from both sides )
8x + 15 = 95 ( subtract 15 from both sides )
8x = 80 ( divide both sides by 8 )
x = 10
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. How much gas would be in the tank after driving for 2 hours? How much gas would be left after tt hours?
Answer: 9
12-1.5t
Step-by-step explanation:
1.5*2=3
12-3=9
1.5*t=1.5t
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.

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

Can you write the equation of a line through
point (3,-4) that is perpendicular to the given line?
Answer:
[tex]m_{1} \times \frac{1}{m_{2}} = - 1 \\ m_{2} = \frac{1}{2} \\ \frac{1}{2} = \frac{y + 4}{x - 3} \\ 2y + 8 = x - 3 \\ 2y = x - 3 - 8 \\ 2y = x - 11 \\ y = \frac{1}{2} x - \frac{11}{2} [/tex]
find three consecutive even integers whose sum 72
22, 24, 26
Step-by-step explanation:
2n - 2 + 2n + 2n + 2 = 72
6n = 72
n = 72/6
n = 12
∴ so three consecutive even integers whose sum is 72 :
2n - 2
= 2(12) - 2
= 24 - 2
= 22
2n
= 2(12)
= 24
2n + 2
= 2(12) + 2
= 24 + 2
= 26
verification
22 + 24 + 26
= 46 + 26
= 72 ✓✓

1. The distance between C (-4,-5) and D (-4,3) is 8
2. The distance between E (-3,2) and F (-8, 2) is 5
3. Since the measurements are not the same, the segments cannot be
congruent

The relation between angle DCF and CFG is co-interior angles, or same side interior angles.
Angle(DCG+CFG)=180
Measure of DCF=180-3x=147 [Because Angle DCF+ACD=180, Angles in a straight line]
Measure of CFG=180-6x-81=33 [Because AngleCFG+HFG=180, Angles in a straight line]

Victor solved this inequality as shown:
Step 1: 3x-5>x+5
Step 2: 2x-5>5
Step 3: 2x>10
Step 4: x>5
What property justifies the work between step 3 and step 4?
Answer:
In step 3: 2x>10 in order to get for x make divided 2 in both sides where you get x>5 in step 4
Answer:
division property of equality
Step-by-step explanation:
First in order to solve we must learn the properties of equality:
Addition property of Inequality:
If a > b , then a + c > b + c
substraction property of inequality
If a > b , then a - c > b - c
Multiplication property of inequality
If a > b , then a * c > b * c (if c > 0)
Division property of inequality
If a > b , then a / c > b / c (if c > 0)
Step 3: 2x>10
Step 4: x>5
When we divide by 2x/2 and 10/2 we get x>5 so we must use the division property of equality
