Answer:
Shana ran 18 miles in a month
Step-by-step explanation:
Shana ran 6 miles in one week. This was 1/3 of what she ran in a month
Let x be the miles she ran in a month
1/3 one third of miles she ran in a month is 6 miles
Now we solve for x
To solve for x , we multiply 3 on both sides
1x= 18
so x= 18
So Shana ran 18 miles in a month
9 large apartments in B
Same ratio
Building A = 12 small : 6 large
= 2 : 1
Building B = 18 small : x large
18/x = 2/ 1
18 = 2x
9 = x
Large apartments in B = 9
Algebra: must make a chart
$/lb * # of lbs = total
Oak 3.4 x 3.4x
Pine 2.6 40-x 104-2.6x
Mixture 2.8 40 112
Now you can set up your equation ( assuming you know how to do equations 'cuz I figure you're in algebra)
3.4x + 104 - 2.6x = 112
.8x + 104 = 112
.8x = 8
10 pounds of oak
30 pounds of pine
The answer is 6.5 meters tall
650 divided by 100
do your 2 loops to the left and you get 6.5
