Roberto's toy car travels at 40 centimeters per second (cm/sec) at high speed and 15 cm/sec at low speed. if the car travels for 15 seconds at high speed and then 30 seconds at low speed, what distance would the car have traveled?

Itook a better photo of the question so y’all can see it i hope it’s a fine photo

At store a, erasers are sold individually. the cost y of x erasers is represented by the equation y=0.75x. the costs of erasers at store b are shown in the graph.

You had $235 in your savings account nine weeks ago. you withdrew the same amount each week for 8 straight weeks. your balence was then $75. solve the equation 235 - 8m=75 to find how much money m you withdrew from your account each week. 2 points
