Answer is B
How I got is because I had to first figure out what 40 seconds worth of heartbeats are equal to. 80 - 48 is 32 divided by 2 is 16. Next, I added 48 and 16 which got me 64. All I had to do next was to add 80 and 16 because the rate of heartbeats per 10 seconds is 16. 80+16=96 and thats how I figured that the answer is B
Answer:
-3x + 11
Step-by-step explanation:
The best method to solve this problem is using distributive property.
2(x + 3) = 2x + 6
5(x - 1) = 5x - 5
(2x + 6) - (5x - 5)
Open parenthesis, change the negative sign in the parenthesis to a positive sign because there is a negative sign in front.
2x + 6 - 5x + 5 = -3x + 11
Hope this helps :)
