2(3v-5)=2(v-11)-4 can someone help me out ?


​

Answers

Answer:

v = -4

Step-by-step explanation:

2(3v - 5) = 2(v - 11) - 4

6v - 10 = 2v - 22 - 4

     +10          +10

6v = 2v -12 - 4

-2v   -2v

4v = -16

divide both sides by 4

v = -4

Hope this helps!!

The value of v = - 4.

We have the following equation -

2(3v - 5) = 2(v - 11) - 4

We have to find out the value of the variable v.

What is the solution of a equation in one variable?

The solution of an equation is the value of variable for which the left hand side is equal to right hand side.

We have the following equation -

2(3v - 5) = 2(v - 11) - 4

2 x 3v - 2 x 5 = 2v - 2 x 11 - 4

6v - 10 = 2v - 22 - 4

6v - 10 = 2v - 26

6v - 2v = - 26 + 10

4v = -16

v = - 4

Hence, the value of v = - 4.

Are you study of a population of 1200 frogs you feel that sold out of every 180 frogs in the population has spots on the back based on the results of the other study how many frogs in the population do not have spots in the back

Answers

Answer: 1,120 frogs

Step-by-step explanation:

If 12 out of every 180 frogs in the population have spots on their backs, the number that do not are;

= 180 - 12

= 168 frogs

168 frogs out of every 180 do not have spots. Out of 1,200 that would be;

= 168/180 * 1,200

= 1,120 frogs

Please can I have an explanation, I am terrible at these kinds of questions! Q- A bag contains red, yellow and blue beads. The ratio of red beads to yellow beads is 2:3 The ratio of yellow beads to blue beads is 5:4 Work out what fraction of the beads are red.

Answers

Answer:

[tex]Red = \frac{10}{37}[/tex]

Step-by-step explanation:

Given

[tex]Red:Yellow = 2 : 3[/tex]

[tex]Yellow: Blue = 5 : 4[/tex]

Required

Determine the fraction of Red

First, we need to link the given ratios.

Since yellow is present in both ratios, we start by making the ratio of yellow equal in both ratios

Multiply this ratio by 5

[tex]Red:Yellow = 2 : 3[/tex]

This becomes

[tex]Red:Yellow = 10 :15[/tex]

Similarly, multiply this ratio by 3

[tex]Yellow: Blue = 5 : 4[/tex]

This becomes

[tex]Yellow:Blue =15:12[/tex]

At this point, we have:

[tex]Red:Yellow = 10 :15[/tex] and [tex]Yellow:Blue =15:12[/tex]

Combine

[tex]Red:Yellow:Blue = 10:15:12[/tex]

The fraction is then calculated as:

[tex]Red = \frac{Red}{Red +Yellow + Blue}[/tex]

This gives

[tex]Red = \frac{10}{10+15+12}[/tex]

[tex]Red = \frac{10}{37}[/tex]

What is the value of the Square Root of 625?

Answers

Answer:

25

Step-by-step explanation:

By prime factorisation, we get:

5 | 625

5 | 125

5 | 25

5 | 5

| 1

. So the prime factors are:

625 = 5 x 5 x 5 x 5

625 = 25 x 25

√625 = 25

what is the measure of angle A in the triangle ​

Answers

2x+4+3x-13+180-116=180
5x+4-129=0
5x=125
x=25
A=3x-13=75-13=62
Okay so we know a straight line is equal to 180 degrees, so first thing to do is subtract 180 by 116 to get angle C
C = 64

then we know all the angles in a triangle add up to 180 also
so we can do 64 + (2x + 4) + (3x - 13) = 180

combine like terms:
55 + 5x = 180

solve: x = 25

plug this back into the equation for angle A:
2(25) + 4

A = 54

It takes about 14 person-hours of labor to break up a driveway and clear away the rubble. It takes about 8 person-hours of labor to pour and smooth concrete for the new driveway.

Answers

Answer: 22 person-hours

Step-by-step explanation:

It takes 14 hours to break up the driveway and then to clear away the rubble.

Then it takes 8 hours to pour the concrete and smooth it.

Total time it will take to break up a driveway, clear away the rubble, pour the concrete, and smooth the concrete will therefore be;

= 14 + 8

= 22 person-hours

Put x = -5 in LHS of the the given equation.

[tex]\text{LHS}=\dfrac{14+10x}{12}\\\\=\dfrac{14+10(-5)}{12}\\\\=\dfrac{14-50}{12}\\\\=\dfrac{-36}{12}\\\\=-3[/tex]
