Drew burned 1,800 calories friday playing 1 hour of basketball and canoeing for 2 hours. on saturday, he spent 2 hours playing basketball and 3 hours canoeing and burned 3,200 calories. how many calories did he burn per hour when playing basketball?

He burnt 1000 calories per hour when playing basketball.

Step-by-step explanation:

Let B be calories burned playing basketball, and C calories burned canoing.

1800 = B + 2C

3200 = 2B + 3C

From 1st equatipn, we get that B = 1800 - 2C

Replacing into the 2nd equation, we have:

3200 = 2(1800-2C) + 3C

3200 = 3600 - 4C + 3C

3200 = 3600 - 1C

C = 3600 - 3200

C = 400

Knowing C, we find B.

B = 1800 - 2C = 1800 - 2*400 = 1800 - 800 = 1000 calories.

He burn 1000 calories per hour when playing basketball

Step-by-step explanation:

Let x be the no. of calories burnt per hour while playing Basketball

Let y be the no. of calories burnt per hour while canoeing

Refer the attached figure

Intersection point gives the solution

(x,y)=(1000,400)

So, he burn 1000 calories per hour when playing basketball

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
