Answer:

y=x+9

Step-by-step explanation:

First, remove the parentheses.

Write in slope-intercept form. (y=mx+b)

The required simplified expression is 1.

Simplify (2 1/4 - 1 2/3) multiplied by 1 5/7

To simplify this expression, we first convert the mixed numbers to improper fractions:

2 1/4 = 9/4

1 2/3 = 5/3

1 5/7 = 12/7

Now, we can multiply the fractions:

(9/4 - 5/3) * (12/7)

Finding a common denominator (12), we can simplify the expression:

(27/12 - 20/12) * (12/7)

Simplifying further:

(7/12) * (12/7) = 1

Therefore, the simplified expression is 1.

Answer:

3.62

Step-by-step explanation:

Let

x = cost of cereal

y = cost of milk

5x + 2y = 31.24

x = $4.80

Substitute into the equation

5x + 2y = 31.24

5(4.80) + 2y = 31.24

24 + 2y = 31.24

2y = 31.24 - 24

2y = 7.24

y = 7.24 / 2

y = $3.62

Therefore,

1 gallon of milk cost $3.62

Answer:

Step-by-step explanation:

Step-by-step explanation:

I think this is it :

For the schones a) 16,16 is double 8 so whatever the ingredients double them!

So it will be: 400g flour

60g caster sugar.... And so on

B) 4 is half 8, so whatever the ingredients half them

Flour = 100g

Sugar = 15g..... And so on

C) 24 is three time 8, so all ingredients triple them

Flour= 600g

Sugar = 90g...and so on

D) 40 is five times 8 so all ingredients multiply by 5

Flour= 1,000 g

Sugar= 150g.... And so on

E) 80 is 10 times 8

So multiply by 10

Flour = 2,000g

Sugar = 300g... And so on

F) 2 is one by fourth of 8

So, flour = 50g

Sugar = 7.5g

For ice-cream:

A) 8 is double 4 so whatever ingredient double

Double cream= 600ml

Milk= 640ml and so on

B) 2 is half 4 so make ingredients half

Double cream = 150ml

Milk = 160ml

C) here because it's only one person

U will divide all the ingredients by 4

So double cream = 300/4 =75ml

Milk = 320/4 = 80ml

So on...

D) for 3 people we will use bit c

For 3 people = double cream= 75x3= 225

Milk = 80x3 = 240ml

And so on

E) so for(c), we found for one person now we can easily use that and find this

Now for 6 people

For person, as we saw, = 75ml

For 6 people double cream = 75x6= 450ml

And for milk for 1 person = 80ml

For 6 people = 80x6= 480ml

And so on

F) 10 people

Double cream = 75ml x 10 = 750ml

Milk = 80ml x 10 = 800ml

For fish pie,

A) 15 is three times 5 so we will multiply 5 to each ingredient

Cod= 1500g

Haddock = 1200g and so one

B) for 1 person we will also divide each ingredient by 5 = Cod = 500÷5 = 100g

Haddock = 400÷5 = 80g and so one

C) we will use bit b for this too

Cod = 100 x 2 = 200g

Haddock = 80g x 2 = 160g and so on

D) 4 people

Cod= 100g x 4 = 400g

Haddock = 80 x 4 = 320g and so on

E) 8 people

Cod = 100 x 8 = 800g

Haddock = 80 x 8 = 640g and so on

F) 11 people

Cod = 100 x 11 = 1100g

Haddock = 80 x 11 = 880g

And so on

Hello!

[tex]\large\boxed{\text{C.} \frac{-15}{2}}[/tex]

3x + 5 = x - 10

Solve for x by isolating the variable.

Subtract 5 from both sides:

3x + 5 - 5 = x - 10 - 5

3x = x - 15

Subtract x from both sides:

3x - x = x - x - 15

2x = -15

Divide both sides by 2:

2x /2 = -15 / 2

x = -15/2.

Answer:

-15/12

Step-by-step explanation:

move the variables 3x-x+5=-10 and collect like terms 3x-5=-10-5 and divide both sides 2x=-15

x=-15/12

Answer: Maggie used 1 1/2 hours

Elizabeth used: 3 × 1 1/2 = 4 1/2 hours

Step-by-step explanation:

Let the time used by Maggie be x

Since it It takes Elizabeth three times as long as Maggie to clean her room. Elizabeth will use: = 3 × x = 3x

Therefore, x + 3x = 6

4x = 6

x = 6/4 = 1.5 hours

Maggie used 1 1/2 hours

Elizabeth used: 3 × 1 1/2 = 4 1/2 hours
