Lving equations of the form ax + b = cx + d 2 3 questions 1 2 3 question 3 the cost of maintaining car a is $300 per year plus $.014 per mile driven. the cost of maintaining car b is $200 per year plus $.025 per mile driven. how many miles are driven in the first year in order for the total costs between car a and b to be equal? car a = 300 + .014x car b = 200 + .025x solve the following equation to determine when costs are equal 300 + .014x = 200 + .025x .011x=100

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
