Answer:
x = 4
Step-by-step explanation:
x + 6 +2x = 2x + 6 + 4
combine like terms:
3x + 6 = 2x + 6 + 4
add numbers:
3x + 6 = 2x + 10
subtract 6 on both sides:
3x + 6 - 6 = 2x + 10 - 6
3x = 2x + 4
subtract 2x from both sides:
3x - 2x = 2x - 2x + 4
x = 4
short explanation:
if you look at the equation, both sides have 6 and 2x which would cancel each other out. That would leave x = 4
A geometric sequence has a4 = 4 and a5 = 7. What is a1 ? Your answer
Answer:
4⁴/7³ or 256/343Step-by-step explanation:
Given GP with
a₄ = 4a₅ = 7a₁ = ?Let the common difference is r, then
a₅ = a₄ra₁r³ = 4a₁r⁴ = 7Solve for r and then a₁:
4r = 7 ⇒ r = 7/4a₁(7/4)³ = 4a₁ = 4*(4/7)³ = 4⁴/7³ = 256/343Given circle B below, find the value of x.
(3x + 10)
(2x - 17)
Answer: 44
Step-by-step explanation:
since the inscribed angle is half of true arc measure, (3x+10)= 2(2x-17).
when you work this out, you get 44 as x.
The value of x from the given figure is 44°. Therefore, option B is the correct answer.
What is relation between angle at the center and the angle at the circumference?The angle subtended by an arc at the center is twice the angle subtended at the circumference . More simply, the angle at the center is double the angle at the circumference.
From the given figure,
Angle at circumference is (2x-17)° and angle at center is (3x+10)°.
Now, (3x+10)°=2(2x-17)°
3x+10=4x-34
4x-3x=10+34
x=44°
Therefore, option B is the correct answer.

Find the missing length of the triangle. If necessary, round your answer to the nearest tenth
Answer: 26
Step-by-step explanation:
a² + b² = c² Use Pythagorean Theorem to find the missing length, a & b are the side of a right triangle, and c is the hypotenuse of the right triangle.
10² + 24² = x² In this triangle, the x was the hypotenuse, which is c, plug 10 and 24 into a and b.
100 + 576 = x²
676= x²
rewrite as
x² = 676
√x² = √676 [solve the square root from both side]
x = 26

Find the LCD of the fractions. Multiplying the denominators 3 and 4 together, we get LCD = 12.
Rewriting the mixed numbers, we get
3 2/3 = 3 8/12 and 3 1/4 = 3 3/12
So the original equation becomes
(3 8/12)x + 3 3/12 = 6
We must now combine like terms: subtract 3 3/12 from both sides of this equation, obtaining:
(3 8/12)x = 6 - 3 3/12, or
(3 8/12)x = 2 9/12. Converting the mixed numbers into improper fractions, we get:
(44/12)x = 33/12. Multiplying both sides by 12 yields 44x = 33
and so x = 33/44 = 3/4
x = 3/4
Alternatively, convert the original mixed numbers into improper fractions right away. Then the original 3 2/3 x+3 1/4=6
becomes (11/3)x + 13/4 = 72/12, or
(44/12)x + 39/12 = 72/12
Multiplying all three terms by 12 yields:
44x + 39 = 72, which simplifies to 44x = 33, or x = 3/4

Each car on a computer train holds 20 people. On a particular morning, 5 cars were 90% full and 3 cars were 65% full. If the people were rearranged to fill as many cars as possible, how many cars would be filled?
Answer:
7 cars
Step-by-step explanation:
The computation of the number of cars to be filled is shown below:
A car that is 90% full and the total people is 20 so 90% would be
= (.90)(20)
= 18
A car that is 65% full and the total people is 20 so 65% would be
= (.65)(20)
= 13
Now
Total number of people = (5)(18) + (3)(13).
= 129
Now the number of cars to be filled is
= 129 ÷ 20
= 6.45
= 7 cars

a book has a hundred and twenty. I have read a quarter of the pages. How many pages do I have?
Answer:
You have 90 pages left.
Step-by-step explanation:
1/4 × 120 = 30 pages read
Therefore
120- 30
=90 pages left to read
Answer:
You read 30 pages of the book.
You have 90 pages left.
Step-by-step explanation:
120 total pages
⇒ 120 = 100%
[tex]\frac{1}{4}[/tex] pages have been read
⇒ [tex]\frac{1}{4}[/tex] = 25%
[tex]\frac{3}{4}[/tex] remaining
⇒ [tex]\frac{3}{4}[/tex] = 75%
120 x .25 = 30 pages read
120 x .75 = 90 pages unread
30 + 90 = 120
A cylinder has a base radius of 6 feet and a height of 12 feet. What is its volume in cubic feet, to the nearest tenths place?
Answer:
its is either 339.3 or 1357.2
Step-by-step explanation:
The volume of the cylinder having radius 6 feet and height 12 feet is 1357.7 cubic feet.
What is volume?Volume is referred to as the area occupied within an object's three-dimensional space.
Given that,
The radius of cylinder r = 6 feet,
And the height of the cylinder h = 12 feet.
To find the volume of the cylinder, use formula,
Volume of cylinder = π × r² ×h
= (22/7) × 6 × 6 × 12
= (22/7) × 432
= 9504 / 7
= 1357.7 cubic feet.
The required volume of the cylinder is 1357.7 cubic feet.
