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

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.

So, it means that 1 apple costs $0.25

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

Step-by-step explanation:

Same Side Interior Angles are supplementary

15 + 5x + 14x - 6 = 180

19x + 9 = 180

19x = 171

x = 9

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

2) Answer: x = 9

Step-by-step explanation:

Corresponding Angles are congruent

13x - 7 = 11x + 11

2x = 18

x = 9

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

3) Answer: x = -10

Step-by-step explanation:

Alternating Interior Angles are congruent

90 = x + 100

-10 = x

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

3) Answer: x = 7

Step-by-step explanation:

Alternating Exterior Angles are congruent

17x + 1 = 120

17x = 119

x = 7
