if you go out to eat and your meal was $72.50 you decide to tip your waiter 15% How much do you pay in total

Answer:

x= 1/2

Step-by-step explanation:

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

−2x+3−5x−4=−3x−8+10x

Step 1: Simplify both sides of the equation.

−2x+3−5x−4=−3x−8+10x

−2x+3+−5x+−4=−3x+−8+10x

(−2x+−5x)+(3+−4)=(−3x+10x)+(−8)(Combine Like Terms)

−7x+−1=7x+−8

−7x−1=7x−8

Step 2: Subtract 7x from both sides.

−7x−1−7x=7x−8−7x

−14x−1=−8

Step 3: Add 1 to both sides.

−14x−1+1=−8+1

−14x=−7

Step 4: Divide both sides by -14.

Answer:

x = 5, supplementary

Step-by-step explanation:

6x + 13 + 14x - 33 = 180

20x - 20 = 80

20x = 100

x = 5

Answer:

The correct answer is 4

Answer:

36 cm

Step-by-step explanation:

3 cm times 6 cm = 18cm

18 cm times the height (2 cm) = 36 cm

So, the answer is 36 cm for the volume.

Answer:

C = 580 children.

A = 420 adult.

Step-by-step explanation:

Let the number of children be C.

Let the number of adult be A.

Translating the word problem into an algebraic equation, we have;

A + C = 1000  .......equation 1

10A + 5C = 7100  .......equation 2

A = 1000 - C .......equation 3

Substituting eqn 3 into eqn 2, we have;

10(1000 - C) + 5C = 7100

10000 - 10C + 5C = 7100

10000 - 7100 = 10C - 5C

2900 = 5C

C = 2900/5

C = 580 children.

Now, to find the value of A.

From equation 3;

A = 1000 - C

A = 1000 - 580

A = 420 adult.

Answer:

B)blocks in 5th row=15+(5-1)(-2)

Step-by-step explanation:

We are given that

Number of block in bottom row=15

Each row has 2 fewer blocks than the previous row

We have to find the formula would you use to find the number of blocks in the 5th row.

Number of blocks in  second row=15-2=[tex]15+1(-2)[/tex]

Number of blocks in third row=15-2-2=[tex]15+2(-2)[/tex]

Number of blocks in 4th row=[tex]15-2-2-2=15+3(-2)[/tex]

Number of blocks in 5th row=[tex]15-2-2-2-2=15+4(-2)[/tex]

Therefore, number of block in 5th row

[tex]15+(5-1)(-2)[/tex]

This is required formula to find the number of blocks in the 5th row

Hence, option B is true.

B)blocks in 5th row=15+(5-1)(-2)

Answer:

The anwser is 321.6 I hope it helps

Answer:

Step-by-step explanation:

y= mx+b is the general equation where m is the slope

y= 1/2 x +6 has the slope 1/2

perpendicular lines have the slope negative reciprocal

so the slope of the ⊥ line is -2

y = -x +b , yet for point (4, 1) the x=4 and y =1

1= -4 +b so b= 5

the equation of the ⊥ line is y= -2x+5

Geometric mean is 26.92582

Answer:

14 servings

Step-by-step explanation:

Step 1

We convert 7 pounds to ounces

0.0625 pound = 1 ounce

7 pounds = x

Cross Multiply

0.0625x = 7

x = 7/0.0625

x = 112 ounces

Step 2

The number of 8 ounce servings she can give to her dog is calculated as:

8 ounces = 1 serving

112 ounces = x servings

Cross Multiply

8 × x = 112 × 1

8x = 112

x = 112/8

x = 14 servings

Therefore, the number of 8 ounce servings she can feed her dog is 14

Answer:

-2/3 is the right answer

=======================================================

Explanation:

[tex]0.\overline{5}[/tex] means that the 5's go on forever because of that horizontal bar over top. So we can write it as [tex]0.\overline{5} = 0.55555\ldots[/tex]

The three dots indicate it goes on forever following that pattern.

Let

x = 0.55555....

Multiply both sides by 10 to move the decimal point 1 spot to the right

10x = 5.55555....

Notice how both x and 10x involve a decimal number such that we have a string of 5's going on forever. If we subtract the two equations, then 10x-x becomes 9x, while the (5.55555....) - (0.55555....) simplifies to 5. The decimal portions cancel out when we subtract since they line up perfectly. We're effectively subtracting 5-0 when we cross off the decimal portions.

After those subtractions, we're left with 9x = 5 which solves to x = 5/9 when you divide both sides by 9.

Use of a calculator should show that 5/9 = 0.555555.... to help confirm the answer. Your calculator may show the last digit to be a 6 instead of a 5, but this is due to rounding. Ideally you should have a string of infinitely many 5's, but the calculator can only how so many digits.

Answer:

x=2 and y=−6

sorry this is pretty long, I did not know if you needed the steps or not

Step-by-step explanation:

−2y−10=x;−10x−y=−14

Solve−2y−10=x for x

−2y−10=x

−2y−10+−x=x+−x

−x−2y−10=0

−x−2y−10+2y=0+2y

−x−10=2y

−x−10+10=2y+10

−x=2y+10

-x/-1=2y+10/-1

x=−2y−10

Substitute−2y−10 for x in−10x−y=−14

−10x−y=−14

−10(−2y−10)−y=−14

19y+100=−14

19y+100+−100=−14+−100

19y=−114

19y/19=-114/19

y=-6

Substitute−6 for y in x=−2y−10

x=−2y−10

x=(−2)(−6)−10

x= 2

x=2 and y=−6
