1/4 cup water

Answers

i don’t think you included the questions but there is a question similar to this on here also so i’ll share what i got for that:

you need to multiply it by 2.5. you determine it by dividing 30 by 12.

1/4 x 2.5 = 5/6
you need 5/6 ounces of yeast

1/3 x 2.5 = 5/6
you need 5/6 cups of powdered milk

6 x 2.5 = 15
you need 15 tablespoons of butter

3 1/2 x 2.5 = 8.75
you need 8.75 cups of bread flour

*Disturabute 4 to (7+x)*

28+4x=64

*Subtract 28 on both sides*

4x=36

*Divide by 4*

x=9

**If you do a Check it works*

4x+7=64

Which equation represents the data in the table? Thanks!

Answers

Answer:

t = 4d + 5

Step-by-step explanation:

Since the slopes in the answer choices are different, we can just find the slope.

Use the formula (y1-y2)/(x1-x2) to find slope. Take points (1,9) and (2,13) and plug them it to get (9-13)/1-2). Simplify to get (-4)/(-1), which simplifies to 4.

The only answer choice with 4 as a slope is D, t = 4d + 5

price of the third shirt and then apply a 7% tax to the total cost of all three shirts.

Including the tax.
what will be the mean cost of each shirt? (Round your answer to the nearest cent).

Including the tax, the mean cost of each shirt is $___?

Answers

Answer:

$49.93

Step-by-step explanation:

Original cost = $56

Cost of 3 shirts:

3*$56 = $168

Cost of 3 shirts with discount:

168 - 1/2*56 =

168 - 28 =

$140

Add tax:

$140*1.07 = $149.8

Mean cost of each shirt:

$149.8/3 = $49.93

An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 9 more than four times the length of the bottom of the triangle. The last side is 11 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.

What is the expression for the perimeter of the triangle?

Answers

Answer:

perimeter = 6x + 15

Step-by-step explanation:

The perimeter of the triangle is the distance around the triangle.

We need to apply our ability to convert word problems in to mathematical expressions.

We were told that the bottom of the triangle is x units.

From the diagram perimeter 4x + 12 + x + 3 + x = 6x + 15

Four times the length of the bottom will be 4x .

12 more than 4 times the bottom will be 4x + 12.

Hence another side of the triangle is 4x + 12.

Finally we were told that the last side is 3 more than the bottom, that will be x + 3.

5w+ 16 = 96

solve for w
simplify your answer as much as possible

Answers

Answer:

w = 16

Step-by-step explanation:

5w+ 16 = 96

or, 5w = 96-16

or, w = 80/5

or, w =16

Answer:

[tex]w=16[/tex]

Step-by-step explanation:

[tex]5w+16=96[/tex]

To solve for [tex]w[/tex], you must first begin by subtracting [tex]16[/tex] from both sides of the equation:

[tex]5w=80[/tex]

Then, divide both sides of the equation by the coefficient of [tex]w[/tex], which is [tex]5[/tex]:

[tex]w=16[/tex]

To check your work, substitute the solved value of [tex]w[/tex], ([tex]16[/tex]), in for [tex]w[/tex] in the initial equation:

[tex]5w+16=96[/tex]

[tex]5(16)+16=96[/tex]

[tex]80+16=96[/tex]

[tex]96=96[/tex]

Since both sides of the equation are equal, our solution is correct!
