In the following questions, determine whether the equation has a solution, no solution, or an infinite number of solutions. Specify which, and then solve the equation if there is a solution.

7(x-5)=x+13

-6x=-5(x-1)-x

-4(x-2)=-2(x-17/2)

3-4x+5=2(8-2x)

2x+3=+2x

2x+3=2x+5

3x+9=2.5x+14

7(x-4)=4x+5

5x-20=-7x-20

3(2x+1)-4x=2x+3

Answers

Answer:

i only know  1. is 8

and also 5. 0= −3

Step-by-step explanation:

Answer and Step-by-step explanation:

7(x-5)=x+13

Distribute the 7, then solve for x.

7x - 35 = x + 13

6x = 48                 (Added 35, subtracted x)

x = 8                      (Divided by 6)

One solution

-6x=-5(x-1)-x

Distribute the -5, then combine like terms. Solve for x.

-6x = -5x + 1 - x      (negative times negative equals positive)

-1 = 0                      (Added 6x, subtracted the x from 1x, subtracted 1)

No solution

-4(x-2)=-2(x-17/2)

Distribute the -4 and -2, then solve for x.

-4x + 8 = -2x + 17     (negative times negative equals positive) (the 2's cancel out to be 17)

-9 = 2x                     (Added 4x, subtracted 17)

-9/2 =  x

One solution

3 - 4x + 5 = 2(8 - 2x)

Distribute the 2, combine like terms. Solve for x.

8 - 4x = 16 - 4x

0 = 8

No solution

2x + 3= +2x

3 = 0

No solution

2x+3=2x+5

0 = 2

No solution

3x+9=2.5x+14

0.5x = 5

x = 10

7(x-4)=4x+5

7x - 28 = 4x + 5

3x = 33

x = 11

One solution

5x-20=-7x-20

12x = 0

x = 0

One solution

3(2x+1)-4x=2x+3

6x + 3 - 4x = 2x + 3

2x + 3 = 2x + 3

0 = 0

Infinite solutions (The reason why this one is infinite is because if you were to plug in any value for x, the result will equal itself, like the 0 = 0.

The equation given was: (x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87.

Using this equation, write the equation with fewer terms.

Answers

Answer:

x = 13

Step-by-step explanation:

(x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87

x + x + 3 + x - 2 + 3x + 9 - 1 = 87

6x + 9 = 87

6x = 87 - 9

6x = 78

x = 78/6

x = 13

X=13 hope that help you out buddy

Pls Answer this using Algebraic expressions

Answers

Answer:

a) A total of 27 parents will receive a call on the third round of calls. b) A total of 39 parents would've been called by the end of the third round of calls. c) There would have to be a total of between 5 and 6 rounds

Step-by-step explanation:

Every time the total number of parents call 3 people, the number of parents tripled in every round.

3 to 9 to 27 to 51 to 153 to 459

Since 153 and 459 are between 5 and 6 rounds, the phone calls will stop between those 2 rounds.

The ratio of a drawing to an object is 6 cm: 40 cm. If the length of the drawing is 36 cm, what is the actual length of the object?

Brainleast? I mean if u give me an answer and an explanation pls.

Answers

Answer:

240

Step-by-step explanation:

If the length of the drawing is 36cm, then we divide 36 by 6, which then equals 6...

Since we changed the 6,  we have to change the 40...

40 x 6 = 240

so the ratio is 36:240 and the object's length equals 240cm

The actual length of the object is 240.

How do you decide where to put a point when you are graphing?

Answers

Step-by-step explanation:

When deciding where to put an ordered pair on a graph its important to understand how ordered pairs work.

An ordered pair is split up into to pieces

(x,y) or number example (3,5)

When graphing the x coordinate will fall on your horizontal line or the line that looks like the horizon.

When graphing the y coordinate it will fall on your vertical line or the line that goes right up into the sky like a rocket.  

To graph (3,5)

Go to the right 3 and up 5

A tree cast a 30 1/2 ft shadow at the time of day when a 2ft stake casts a 7 2/3 ft shadow.Estimate the height of the tree.

Answers

Answer:

The tree is about 8 feet.

Step-by-step explanation:

7 2/3 = 7.6 as a fraction.

30 1/5 = 30.5 as a fraction.

Know, we must divide 30.5 by 7.6.

30.5 ÷ 7.6 = 4 when rounded to the nearest whole number.

Since we know that the stake is 2 feet, we must multiply this by 4, since the other shadow is 4 times the amount of the stake.

2 x 4 = 8

This means the tree is about 8 feet.

The tree is about 8 feet
