heather can do 2 problems in 10 minutes....60 minutes in an hr
2/10 = x / 60...2 problems to 10 min = x problems to 60 min
10x = 120
x = 120/10
x = 12....so she can do 12 problems in 1 hr
Joel can complete 3 problems in 15 minutes...
3/15 = x / 60
15x = 180
x = 180/15
x = 12....so he can do 12 problems in 1 hr
so 24 problems can be done in 1 hr
Heather started with 3 problems done and Joel started with 2 problems done....added = 5 problems already done
and it is asking between 30 and 50 hrs.....so there is no equal sign in ur problem
ur answer is : 30 < 24x + 5 < 50 <==
Answer:
30
Step-by-step explanation:
all triangles =180
because 180 -120 =60whch is the missing inside angle
and we know that this is a right angle
so we subtact what we know to find what we dont
180-(60+90)=30
(150)
180-150=30
Answer: Max should read 22 full pages a day, and he will have 16 pages left to read.
Step-by-step explanation:
First, divide 676 by 30. The answer you get is 22.53.
This means that Max should read 22 pages a day.
Next, you should multiple 22 by 30. The answer you get is 660.
Finally, subtract 660 from 676. You will end up with 16.
