bro which class question is this then I can help you with ur question
Answer: D
Step-by-step explanation:
A. 3 + -7 < -4
-4 < -4
X
this one isn’t a solution
B. 3 + -7 ≤ -4
-4 ≤ -4
this works, let’s try the other equation
3(3) + 2(-7) < -5
9 + -14 < -5
-5 < -5
X
this one doesn’t work either, let’s go on to the next one
C. the first equation is the same as the first one in A, and that didn’t work, so we know that the whole thing doesn’t work and we don’t have to do any math
D. we know the first equation works because we did it in B
let’s go on to the second equation
3(3) + 2(-7) ≤ -5
9 -14 ≤ -5
-5 ≤ -5
this works, so that means that both equations work and the whole thing works :)
Monday= 13.45
Tuesday=9.5
wednesday/Friday= x/3
1st. you add Monday and Tuesday
2nd. you subtract the total 42.6 with added numbers of step one
3rd. finally you divided the total of step 2 by 3
finally you shall receive your answer.
Answer:
I'm not to sure but I think it's A, 38.4 mph. By the way are you from Bay doing this for spring break math hw?
Step-by-step explanation:
12/3.75 is 3.2; 3.2*12 is 38.4. do 12/3.75 meaning 3.2 miles every hour multiplied by 12 to get 38.4 miles.
