How to solve 2(x+7)=-4x+14

Mathematics
1 answer:
Temka [501]3 years ago
8 0

Answer:

distribute the 2 on the left side to become 2(x+7)-->2x+14=-4x+14, add 4x to both sides to become 2x+14+4x=-4x+14+4x-->6x+14=14, subtract 14 from both sides 6x+14-14=14-14-->6x=0 and divide both sides of the equation by 6 to get x alone, 6x/6=0/6-->x=0 so x would equal 0.

The volume V of a cone varies jointly as the area of the base B and the height
seraphim [82]

Answer:

h = 9 cm.

Step-by-step explanation:

V = kBh   where k is the constant of variation.

From the given info:

32 = k*16*6 = 96k

So k = 32/96 = 1/3.

So we have the equation of variation:

V = 1/3Bh

When V = 60 B = 20, so:

60 = 1/3 20h

20h = 60 * 3 = 180

h = 180 /20 = 9.

The interior angles of a hexegon are in the ratio 3:3:4:5:6:7. Find; (a) The size of the smallest angle. (b) The size of the lar
elena-s [515]

Answer:

a) 77.13

b) 179.97

Step-by-step explanation:

3x + 3x + 4x + 5x + 6x + 7x = (6 - 2) × 180

28x = 720

x = 720/28

x ≅ 25.71

3 × 25.71 = 77.13 = smallest angle

7 × 25.71 = 179.97 = largest angle

A rectangle has a height of 7x^27x 2 7, x, squared and a width of 3x^2+8x+73x 2 +8x+73, x, squared, plus, 8, x, plus, 7. Express
abruzzese [7]

The expression 21x⁴ + 56x³ + 49x² represents the area of the entire rectangle.

<h3>What is the area of the rectangle?</h3>

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

The area of the rectangle = length x width

= (3x² + 8x + 7)(7x²)

\rm =7x^2\cdot \:3x^2+7x^2\cdot \:8x+7x^2\cdot \:7

= 21x⁴ + 56x³ + 49x²

Thus, the expression 21x⁴ + 56x³ + 49x² represents the area of the entire rectangle.

Eli claims that the product of and is . Which explains whether Eli is correct?
Shalnov [3]

Answer: last option.

Step-by-step explanation:

According to the Product of powers property, you have:

a^n*a^m=a^{(n+m)}

As you can see, when you can add the exponents when you have powers with equal base.

Then,  6^5  and 5^{-3} do not have the same base, therefore, the exponents can't be added.

Therefore, Eli is incorrect, because he added the exponents even though the bases are not the same.

Tim and Nikko bought new computers. Tim spent $55 more than 2/3 of the amount that Nikko spent for his computer. The total amoun
juin [17]

Answer:

<h2>C.  $1,689.00</h2>

Step-by-step explanation:

Let the amount spent by Tim be x and the amount spent by Nikko be y

If Tim spent $55 more than 2/3 of the amount that Nikko spent for his computer, then amount spent by Tim will be x = 55+2/3 y

Since the total amount that Tim and Nikko spent for their computers was $2,870 then;

x+y = $2,870

Substituting  x = 55+2/3y into the equation above, we will have;

55+2y/3 + y = 2,870

(165 + 2y)/3 + y = 2,870

(165 + 2y+3y)/3 = 2,870

cross multiply

165 + 2y+3y =  3*2870

165+5y = 8610

5y = 8610-165

5y = 8445

y = 8445/5

y = 1689

<em>Hence Nikko spent  a sum of $1,689.00 on his computer.</em>
