10-7X-5+12x=0

Explain

Answers

Answer 1
10-7x-5+12x=0 Combine like terms
10-5 is 5 and -7x+12x is 5x so that makes
5x+5=0 Subtract 5 from both sides
5x=-5 Divide both sides by 5
x=-1
Answer 2

Answer:

x = -1

Step-by-step explanation:

[tex]10 - 7x - 5 + 12x = 0[/tex]

➡️ [tex]5 - 7x + 12x = 0[/tex]

➡️ [tex]5 + 5x = 0[/tex]

➡️ [tex]5 + 5x - 5 = 0 - 5[/tex]

➡️ [tex]5x = 0 - 5[/tex]

➡️ [tex]5x = - 5[/tex]

➡️ [tex]5x \div 5 = - 5 \div 5[/tex]

➡️ [tex]x = - 5 \div 5[/tex]

➡️ [tex]x = - 1[/tex]

Answers

Answer:

Dan is correct

Step-by-step explanation:

First, I calculated the amount of hours that the graph shows in total, coming up with a total of 3,085 hours. I do this by multiplying the number of adults surveyed by the number of hours they spent. So for the first column, (80+70)*1, second column, (90+80)*2, third column, (135+130)*3, fourth column, (140+135)*4, and fifth column, (65+75)*5 if you get what I mean. Then I add up all values. Knowing that there were two sets of 500 American adults interviewed already, I came to the conclusion that 1,000 total adults were surveyed. Finally, I divided the total number of hours(3,085) by the total number of adults interviewed (1,000) to get a mean of 3.085 hours, rounding it to 3 hours and proving that Dan is correct.

B. 74°
C.106°
D.116

Answers

Answer:

B) 74

Step-by-step explanation:

This is an icoseles triangle because of the 2 lines in each side. This makes <Y equal to <Z

Given:

<Y = <Z

All triangle angles add up to 180 so:

<W + <Y + <Z = 180

<W + 53 + 53 = 180

<W + 106 = 180

<W = 180 - 106

<W = 74

Step-by-step explanation:

1- first simplify the fractions in the bracket

= 3/8 (-17/8 7/12)

2- then calculate within the brackets

= 3/8 (-51/14)

3- lastly multiply & divide

3/8 (-51/14) = -7/68

Eva needs to order some new supplies for the restaurant where she works. The
restaurant needs at least 749 forks. There are currently 173 forks. If each set on sale
contains 18 forks, use the drop-down menu below to write an inequality representing
s, the number of sets of forks Eva should buy.

Answers

Answer:

s≥32

Step-by-step explanation:

Subtract 173 from 749:  576

since each set has 18 forks, divide 576 by 18: 32

since the restaurant needs at LEAST 32 more sets, s has to be greater or equal to 32

[tex]\frac{sin\left(90\right)}{x}=\:\frac{sin\left(60\right)}{\left(\frac{\left(6\cdot \:sin\left(90\right)\right)}{sin\left(45\right)}\right)}[/tex]

Step-by-step explanation:

Answer: 4sqrt(6)

Explanation:

Sin(theta) = opp/hyp => hyp = opp/sin(theta)

Find opp:

opp = sqrt(6^2 + 6^2)
= sqrt(72)
= 6sqrt(2)
= 6 x 1.41

Hyp(also is x) = (6 x 1.41)/Sin(60°)
= (6 x 1.41 )/0.86
= 9.83
= 10 (round up)

And 4sqrt(6) = 9.79 = 10 (round up)

Thus I concluded that x = 4sqrt(6)

a video game. He receives $20 from his grandfather and deposits $15
of it into his savings account. What is Alan's balance now?

Answers

Step-by-step explanation:

$115.78 + $15.00 = $130.78

$130.78 + $7.50 = $138.28

$138.28 - $35.90 = $102.33

$102.33 + $20.00 = $122.33

Answers

Answer:

1/5

Step-by-step explanation:

the prob that you will pick a blue marble would be 12/16, easy.

then the prob of picking a yellow marble after that would be 4/15 since one marble is already missing. multiply the numerator and denominator of each fraction. so 12 x 4 and 16 x 15 to get 48/240. then divide each by 48 to get 1/5.

the answer is 1/5

calculate the length of the legs of an isosceles triangle.The base is less than the other congruent legs by two units.The perimeter of the triangle is 22 meter .

Answers

Answer:

Sides = 8 each and base = 6

Step-by-step explanation:

Let congruent legs = x, then the base is x - 2 so,

24 = 3x

8 = x (sides)

base = 8 - 2 = 6

Step-by-step explanation:

times mean multiplication and minus mean subtraction, I hope this helps.

An equation is formed of two equal expressions. An equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

As stated by Sarah that "the number of tiles in each figure was always 3 times the step number minus 2", this can be written in the form of an equation as shown below.

Number of tiles = [3 × (Number of steps)] - 2

Assume that the number of tiles is represented by y, while the number of steps can be written as x. Therefore, we can write the equation as,

y = 3x - 2

Now, let's check the equation,

When the number of steps is 3, the number of tiles is 7.

y = 3(3) - 2

y = 9 - 2

y = 7

Since the number of tiles is the same, therefore, the equation is correct.

Hence, an equation that fits Sarah's way of seeing the relationship is y = 3x - 2.
