The equation c= 0.25n can be used to find the cost (c) of buying n number of apples.
aksik [14]

Answer:

(a) The constant of proportionality is 0.25

(b) 1 apple = $0.25

(c) $3 = 12 apples

Step-by-step explanation:

Given

c= 0.25n

Solving (a): The constant of proportionality;

For an equation:

c=kn

Where

k = constant of proportionality

By comparing: c=kn to c= 0.25n

k = 0.25

Hence, the constant of proportionality is 0.25

Solving (b): What information does k = 0.25 gives.

It represents the unit rate.

<em>So, it means that 1 apple costs $0.25</em>

<em></em>

Solving (c): Number of apples for $3.

This means that c = 3

Substitute 3 for c in c= 0.25n

3 = 0.25n

Make n the subject

n = \frac{3}{0.25}

n = 12

lbvjy [14]

Answer:

SETS ≥ 44.5

Step-by-step explanation:

748-214=534, Leah still needs at least 534 knives.

Let X be the numbers of sets of knives, 12X ≥ 534, X ≥ 44.5.

The minimum of X is 45 since there's no shop sells "0.5" sets of knives.

1) Answer: x = 9

<u>Step-by-step explanation:</u>

Same Side Interior Angles are supplementary

15 + 5x + 14x - 6 = 180

19x + 9 = 180

19x = 171

x = 9

***************************************************************

2) Answer: x = 9

<u>Step-by-step explanation:</u>

Corresponding Angles are congruent

13x - 7 = 11x + 11

2x = 18

x = 9

***************************************************************

3) Answer: x = -10

<u>Step-by-step explanation:</u>

Alternating Interior Angles are congruent

90 = x + 100

-10 = x

***************************************************************

3) Answer: x = 7

<u>Step-by-step explanation:</u>

Alternating Exterior Angles are congruent

17x + 1 = 120

17x = 119

  x = 7
