uranmaximum [27]

Answer:

Equation:

21 = 1 + m

Solution:

20 = m

Step-by-step explanation:

What we know:

  • Karim drank 1 cup of milk at breakfast
  • Karim drank a total of 21 cups of milk
  • m = the amount of milk, in cups, Karim drank after breakfast

We know that Karim drank 21 cups of milk in a day. In an equation, that would look like this:

21 =

What does 21 equal?

The amount of milk Karim drank at breakfast plus the amount of milk Karim drank after breakfast.

21 = milk at breakfast + milk after breakfast

Let's substitute what we know into this equation:

21 = milk at breakfast + milk after breakfast

21 = 1 + m

Now that we have our equation, let's solve.

21 = 1 + m

-1    -1

20 = m

Answer:

y=\frac{x+2}{4} or y = 0.25x + 0.5

Step-by-step explanation:

You need to try change the subject from x to y.

x = 4y - 2

We first move -2 to the left, making the equation

x + 2 = 4y i.e.

4y = x + 2

We then divide both sides by 4.

y=\frac{x+2}{4} or y = 0.25x + 0.5

We now have successfully made y the subject, and effectively solving the equation.

ou decide to bake some cakes. You need 150 g of flour for 12 cakes. How much flour do you need for 30 cakes? g
Brilliant_brown [7]
Short answer: 375 grams

Remark
You only need to set up a direct proportion

Givens
flour for 12 cakes = 150 grams
Number of cakes initially = 12
Amount of flouer for 30 cakes = x
Number of cakes = 30

Proportion
amount flour for 12 cakes / 12 cakes  = x / 30

Sub and solve
150 grams / 12 cakes = x / 30 cakes  Cross multiply
150 * 30 = 12 *x                                  Multiply the left side. 
4500 = 12 x                                         Divide both sides by 12
4500/12 = x
375 grams for 30 cakes. <<<<< Answer
