If two sweaters and four shirts cost $150, and four sweaters and three shirts cost $200, find the price of each shirt and each s

STALIN [3.7K]

Answer:

shirt = $20

sweater = $35

Step-by-step explanation:

This question would be solved using simultaneous equation

Let the price of sweater be represented by a

Let the price of shirt be represented by b

The following equations can be derived from the question

2a + 4b = 150 equation 1

4a + 3b = 200 equation 2

Multiply equation 1 by 2

4a + 8b = 300 equation 3

Subtract equation 2 from 3

5b = 100

divide both sides of the equation by 5

b = 20

substitute for b in equation 1

2a + 4(20) = 150

2a + 80 = 150

collect like terms

2a = 150 - 80

2a = 70

divide both sides by 2

a = 35

Price of sweater = $35

Price of shirt = $20

Part 1: The right answer is Option B.

Part 2: The right answer is Option B.

Step-by-step explanation:

Given,

1 hour = 120 calories

Part 1: How many calories are burned per minute when walking on a treadmill?

1 hour = 120 calories

1 hour = 60 minutes

Therefore,

60 minutes = 120 calories

1 minute = $\frac{120}{60}=2\ calories$

2 calories are burned per minute.

The right answer is Option B.

Part 2: Assuming you walk at a constant rate and burn 120 calories per hour, how many minutes will it take to burn 75 calories.

From part 1;

1 minute = 2 calories

1 calorie = $\frac{1}{2}\ minute = 0.5\ minutes$

75 calories = 75*0.5 = 37.5 minutes

The right answer is Option B.

Cut up the shape into triangles, rectangles or trapezoids and calculate the individual areas.

Here,

Top triangle = (1*7)/2 = 3.5

Left triangle = (4*5)/2 = 10

Right trapezoid = (4+5)*3/2=13.5

So total area = 3.5+10+13.5=27
