Mrs. Kelly bought a bag of flour that holds 1623 cups of flour. Each loaf of banana bread uses 23 cup of flour.

How many loaves of banana bread can she make?

Answers

Answer:

69 loaves

Step-by-step explanation: (Sorry if you don't understand I am not that good at explaining)

First you need to divide 1,623 by 23 because each loaf is 23 cups of flour.

So 1,623 divided by 23 equals 70.56 but you can't have a fractioned number so it needs to be a whole loaf of bread so she can make 69 loaves of bread

Answer:
70.57 loaves of banana bread
Explaintion:
1,623 ➗ 23 = 70.5652173913043
Rounded: 70.57

Answers

Answer: 120

120

Step-by-step explanation:

I honestly can’t explain but I think you have to do this (actually I did the work so I’m right)

P/w = part/whole = ?/400

%/100= percent/100 = 30%/100

These numbers are equivalent

If you don’t understand the top then here is how to do the work-

400x30=12000

12000/100=120

Therefore it’s 120

Each pair of points lies on a line with the given slope. Find y.

Answers

Answer:

3/4

Step-by-step explanation:

If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in

1/4(x)=y

1/4(3)=y

3/4=y

And the other one is incorrect

Solve 7x – 9 = 28 + 4(x – 1).
A.x = 11
B.x = -11
C.x = -3

Answers

Answer:

x=11

Step-by-step explanation:

7x-9=28+4(x-1)

7x-9=28+4x-4

7x-9=24+4x

7x-9-4x=24

3x-9=24

3x=24+9

3x=33

x=33/3

x=11

7x -9= 28 + 4x-4

7x -9=24+4x

7x-9+9=24+9+4x

7x- 4x= 33 + 4x-4x

3x/3=33/3

X=11

Answer:

[tex]r=\frac{q-ps}{p}[/tex]

General Formulas and Concepts:

Order of Operations: BPEMDASEquality PropertiesDistributive Property

Step-by-step explanation:

Step 1: Define equation

[tex]q=p(r+s)[/tex]

Step 2: Solve for r

Distribute p:                              [tex]q=pr+ps[/tex]Subtract ps on both sides:       [tex]q-ps=pr[/tex]Divide both sides by p:            [tex]\frac{q-ps}{p} =r[/tex]Rewrite:                                     [tex]r=\frac{q-ps}{p}[/tex]

Step-by-step explanation: To solve for r, start by distributing the p

through the parentheses on the left side to get q = pr + ps.

Next, isolate the r term by subtracting ps from both sides to get -ps + q = pr.

Finally, to get r by itself, divide both sides by p and we have -ps + q/p = r.

Answer:

x + 2x = 108

Step-by-step explanation:

Let x be the number of oranges sold on Thursday

The number of oranges sold on Friday is twice as many or 2 times x, 2x

The total sold on  the two days is 108.  Add the number sold on Thursday and Friday together and let it equal to 108

x + 2x = 108

So lets say you sold ‘x’ number of oranges on Thursday.On Friday you sold double,therefore ‘2x’. And altogether combining the sales on Thursday and Friday you sold 108 oranges. Therefore if we add the number of oranges sold on Thursday and Friday we will get 108 oranges.
The equation will be: x(number of oranges sold on Thursday) + 2x( number of oranges sold on Friday) = 108 (total number of oranges sold altogether)
x + 2x = 108

2. $360 x %40=$14,000

$14,000/100=144   360-144 = 216

$216 x %20 = $4,320/$100= $43.20

$216-43.20= $172.8

Find the equation of a line whose slope is one-half and y-intercept is 2.

Answers

Answer:

[tex]y=\frac{1}{2} x+2[/tex]

Step-by-step explanation:

To find this you can use slope-intercept form which is y=mx+b where m=slope and b=y-intercept. You just have to plug both numbers in, giving you [tex]y=\frac{1}{2} x+2[/tex].

The equation of a line is y=mx+c
Where m is the gradient and c is the y intercept
If you substitute m with 0.5 and c with 2 the answer will be y=0.5x+2
