The banana bread card states it serves 10 people. How much flour is required to make enough bread for 30 people?

The card says we need 1 & 1/2 cups of flour

Let's convert this to decimal form

1 & 1/2 = 1 + 1/2

1 & 1/2 = 1 + 0.5

1 & 1/2 = 1.5

The mixed number 1 & 1/2 is equivalent to the decimal number 1.5

Now multiply this by 3. This is because the recipe originally serves 10 people, but we want to serve 3 times as many people (3*10 = 30 total).

So,  3*1.5 = 4.5

Now convert back to a mixed number

4.5 = 4 + 0.5

4.5 = 4 + 1/2

4.5 = 4 & 1/2

We'll need 4 & 1/2 cups of flour.

Here's another way to approach the problem

Multiply 3 by 1 & 1/2 to get

3*(1 & 1/2) = 3*(1 + 1/2)

3*(1 & 1/2) = 3*1 + 3*1/2

3*(1 & 1/2) = 3 + 3/2

3*(1 & 1/2) = 3 + (2+1)/2

3*(1 & 1/2) = 3 + 2/2 + 1/2

3*(1 & 1/2) = 3+1 + 1/2

3*(1 & 1/2) = 4 + 1/2

3*(1 & 1/2) = 4 & 1/2

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
