Kevin is participating in a dance marathon . He writes the equation m=3h+30 to represent the amount of money he collects from each sponsor for dancing h hours. What number represents the rate of change? What number represents the amount of money Kevin started with

3 is the number that represents the rate of change, and 30 is the number that represents the amount of money that Kevin started with.

Step-by-step explanation:

Well for me it's simple, if you know that "h" represents "hours", and we know that we will have to multiply 3 into "h" to solve the equation, this will eventually change things, keyword change, so we now know that 3 represents the rate of change, and since 30 is the only number left, 30 is the amount of money Kevin started with.

5x+2x=49

7x=49

x=7. 35 apples

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
