46) Joe has a collection of nickels and dimes that is worth $6.50.14 the number of dimes wes doubled and the number of nickels was increased by 12. then the value of the coins would be $11.30. How many dimes does he
have?
A) 46
B) 21
C) 12
D) 12

what is the original number? you forgot to add it.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

1. minimum

2. 6400

3. eight

hope this !

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
