2x+8 + 3x+6 = 7x i need help fast

Answers

Answer 1

Answer:

x=7 Hope this helps :)

Step-by-step explanation:

Let's solve your equation step-by-step.

2x+8+3x+6=7x

Step 1: Simplify both sides of the equation.

2x+8+3x+6=7x

(2x+3x)+(8+6)=7x(Combine Like Terms)

5x+14=7x

5x+14=7x

Step 2: Subtract 7x from both sides.

5x+14−7x=7x−7x

−2x+14=0

Step 3: Subtract 14 from both sides.

−2x+14−14=0−14

−2x=−14

Step 4: Divide both sides by -2.

−2x

−2

=

−14

x=7

Answer 2

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 7}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{2x + 8 + 3x + 6 = 7x}[/tex]

Add the like terms : 2x and 6

[tex] \dashrightarrow{ \sf{5x + 8 + 6 = 7x}}[/tex]

Add the numbers : 8 and 6

[tex] \dashrightarrow{ \sf{5x + 14 = 7x}}[/tex]

Move 7x to left hand side and change it's sign

Similarly, move 14 to right hand side and change it's sign

[tex] \dashrightarrow{ \sf{5x - 7x = -14}}[/tex]

Subtract 7x from 5x

[tex] \dashrightarrow{ \sf{ - 2x = - 14}}[/tex]

Divide both sides by -2

[tex] \dashrightarrow{ \sf{ \frac{ - 2x}{ - 2} = \frac{-14}{ - 2}}} [/tex]

Calculate

[tex] \dashrightarrow{ \boxed{ \sf{x = 7}}}[/tex]

Hope I helped!

At 8 a.m. the temperature was 56°F. By noon a storm had arrived, and the temperature was 43°F. Which describes the change in the temperature from 8 a.m. until noon?

Answers

Answer:

13°F

Step-by-step explanation:

Given that,

Initial temperature = 56°F

Final temperature, = 56°F

We need to find the change in temperature. It is equal to the difference between final temperature and the initial temperature. So,

[tex]\Delta T=T_f-T_i\\\\\Delta T=43^{\circ}F-56^{\circ} F\\\\\Delta T = 13^{\circ} F[/tex]

So, the change in temperature is 13°F.

Answer:

13°F

Find the root

X^3-125=0

Answers

Given Equation:

[tex] \huge {\sf {{x}^{3} - 125 = 0}} [/tex]

To Find:

The root of the equation.

Solution:

By adding 125 to both the sides, we get

[tex] \huge {\sf { {x}^{3} = 125}} [/tex]

Take cube to the RHS (Right Hand Side), we get

[tex] \huge {\sf { x = 5}}[/tex]

Answer: x = 5

The solution to the expression is x = 5.

We have,

Expression:

x³ - 125 = 0

This can be written as,

x³ = 125

Now,

Cube of 5:

5³ = 5 x 5 x 5 = 125

Now,

x³ = 5³

Cube cancels out on both sides.

x = 5

Thus,

The solution to the expression is x = 5.

A toothpaste company surveyed 36,219 customers about their favorite toothpaste flavor . The date will be used be help the company decide what flavors to continue making . To the nearest thousand, about how many customers were surveyed.

Answers

Answer:

To the nearest thousands; 36,000 customers were surveyed.

Step-by-step explanation:

Conversion of figures to the nearest thousand often requires rounding up digits that are not up to 5 in the place of hundreds to zero and rounding up the digits that are up to 5 in the place of hundreds to one, therefore, adding it to the value of the previous thousands.

From the given  question, to round up the number of customers surveyed in the company, we have the following:

since we are given the value to be 36,219

9 is in unit position

1 is in tens

2 is in hundreds

6 is in thousands

3 is in ten thousand

since the value of 2 in hundred is not up to 5, we round it up to zero, Then our value becomes 36,000 to the nearest thousand.

(A) positive: (–2, 2)

(B) range: (–3, 4]

(C) domain: (–3, 3]

(F) increasing: (–3, –1)

What are the domain and range of the function?

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

The vertical span of the range is from y > -3 to y = 3. The interval for this is [(-3, 3].

The horizontal range, from x > -3 to x = +4, represents the domain. This is represented by the interval [(-3, 4].

The graph decreases to the right, it gets smaller. There is no mention of the endpoints. The x values are in the range (-1, 4).

The graph is increasing where it goes up to the right. The endpoints are generally not included. The x-values are in the interval (-3, -1).

The region of the graph that is above the x-axis is positive. The interval contains x. (-2, 2).

Step-by-step explanation:

Let p = poonams age

Let s = shalini's age

p = 5s

p+s = 72

Substitute the first equation into the second equation

5s+s = 72

Combine like terms

6s= 72

6s/6 = 72/6

s = 12

p = 5s =5*12 = 60
