6x + 2 - 8x + 7 = 4x + 1 ← simplify left side
9 - 2x = 4x + 1 ( subtract 4x from both sides )
9 - 6x = 1 ( subtract 9 from both sides )
- 6x = - 8 ( divide both sides by - 6 )
x = [tex]\frac{-8}{-6}[/tex] = [tex]\frac{4}{3}[/tex] → A

Can someone help me on this
Step-by-step explanation:
(a) n² + 3
First term = 1² + 3 = 4
Second term = 2² + 3 = 7
Third term = 3² + 3 = 12
Fourth term = 4² + 3 = 19
10th term = 10² + 3 = 103
(b) 2n²
First term = 2(1)² = 2
Second term = 2(2)² = 8
Third term = 2(3)² = 18
Fourth term = 2(4)²= 32
10th term = 2(10)² = 200
Hence, this is the required solution.

In △ABC, m∠C=95°, a=26, and b=17. Identify c rounded to the nearest tenth.
Answer:
32.3
Step-by-step explanation:
According to the Law of Cosines, for any △ABC with sides lengths a, b, and c, a2=b2+c2−2bccosA; b2=a2+c2−2ac cosB; and c2=a2+b2−2abcosC.
Set up the equation for the Law of Cosines:
c2=a2+b2−2abcosC
Substitute the known values into the Law of Cosines:
c2=262+172−2(26)(17)cos 95°
Square the values and multiply:
с2=676+289−884cos95°
Add:
c2=965−884cos95°
Take the square root of both sides:
c=965−884cos95°
Calculate the value of cosine 95° on a calculator and solve for the positive value of square root to find c:
c≈32.3
Therefore, c≈32.3.
So, the length of side c is approximately 32.3 units.

It took 25.5 bottles to fill the cooler and each bottle contained 1.8 litters. How many litters are in the cooler
Answer:
Step-by-step explanation:45.9 liters
It took 25.5 bottles to fill the cooler and each bottle contained 1.8 liters. Hence, the amount of water that the cooler will hold is equal to the total amount of water in 25.5 bottles. Amount of water in 1 bottle=1.8 liters. =45.9 liters.
Angela purchased a storage cube with a volume of 10 cubic feet. She wants to put it on a shelf that is 24 inches tall.
A.
Yes, because the height of the cube is approximately 4.93 inches.
B.
Yes, because the height of the cube is approximately 2.15 inches.
C.
No, because the height of the cube is approximately 25.85 inches.
D.
No, because the height of the cube is approximately 39.96 inches.
Answer:
c
Step-by-step explanation:
10 cubic feets volume is equivilant o 25.85 inches.
No, because the height of the cube is approximately 25.85 inches. Option C is correct.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing. A cube's volume can be calculated using its side cube.
Given that, Angela bought a storage unit with a 10 cubic foot capacity. It will go on a shelf that is 24 inches tall,
Volume, V = 10 cubic feet
Height, h =24 inches
The volume of a cube is found as the cube of the side.
Volume of cube = side³
V=a³
10=a³
Take a cube root of 10 to find the value of a,
a=2.15 feet
We can convert feet into inches, in one foot there are 12 inches.
1 feet = 12 inches
2.15 feet = 2.15 × 12
2.15 feet = 25.85 inches
Thus, no because the height of the cube is approximately 25.85 inches. Option C is correct.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 40 N acts on a certain object, the acceleration
of the object is 10 m/s. If the acceleration of the object becomes 6 m/s?, what is the force?
Answer:
New force = 24 N
Step-by-step explanation:
The force acting on the object varies directly with the object's acceleration
i.e.
[tex]\dfrac{F_1}{F_2}=\dfrac{a_1}{a_2}[/tex] ...(1)
We have,
F₁ = 40 N, a₁ = 10 m/s², a₂ = 6 m/s₂, F₂ =?
Put all the values in equation (1).
[tex]F_2=\dfrac{F_1a_2}{a_1}\\\\F_2=\dfrac{40\times 6}{10}\\\\F_2=24\ N[/tex]
So, the new force becomes 24 N.

On a test, Sarah got 48 questions correct out of 50. What percent did she get on her test?
Answer:
96%
Step-by-step explanation:
48 / 50 = 0.96
0.96 x 100% = 96%
Sara got a 96% on her test
she got a 48/50. Percentage is 'something'/100. So you * both sides by 2 so 50 is 100 and 48 is 96
