Answer:
Step-by-step explanation:
"Tamara runs 5 miles each week"
Let Tamara runs 'x' weeks then equation that represents the total distance covered by Tamara will be,
1). y = 5x
2). Here 'y' is directly proportional to the number of weeks 'x'.
3). And the graph when plotted will start from 0. Therefore, graph (1) will be the graph for the given equation.
"Tamara runs 5 minutes more than she walks each day."
1). If Tamara walks 'x' minutes daily and she runs for y minutes then relation between x and y will be,
y = x + 5
2). y and x are non proportional.
3). Graph will have y-intercept = 5
Answer:
- 1/4
- 3/5
Step-by-step explanation:
You find the part by expressing the ratio as a fraction, then simplifying.
1. 5/20 = (1·5)/(4·5) = (1/4)·(5/5) = 1/4
5 is 1/4 of 20.
__
2. 12/20 = (3·4)/(5·4) = (3/5)·(4/4) = 3/5
12 is 3/5 of 20.

Answer:
- B. negative one and 39 over 45
Step-by-step explanation:
Convert this into expression:
- negative four and one fifth ÷ two and one fourth
- - 4 1/5 ÷ 2 1/4
<h3>Step 1</h3>
Convert each to improper fraction:
- - 4 1/5 = - 21/5
- 2 1/4 = 9/4
<h3>Step 2</h3>
Divide the fractions:
- 21/5 ÷ 9/4 =
- 21/5 × 4/9 =
- 84 / 45 =
- 1 13/15
The matching choice is B.
