Answer:
14.4
Step-by-step explanation:
Hope this helps you :)
The domain will be x>0 because their cannot be negative people or negative cost of living per person.
Assume x are Erica's classes & y are Bo's classes.
x+y=35
x=2y-13
Replacing the value of x into the first equation
2y-13+y=35
3y=35+13
y=16 classes
x=2*16-13=19 classes
Answer:
60.8 mm^2
D
Step-by-step explanation:
Remark
You have to assume that the left and right sides are both 9.3. The question is undoable without that assumption.
Next, you have to assume that The top is 7.8 mm across and both ends meet 9.3 at right angles. Again if that is not true, the problem can't be done. Sometimes people making these questions make errors which you are asked to correct.
Solution
So let's assume that everything I've assumed is correct.
Find the area of the rectangle.
Area = L*W
L = 9.3
W = 7.8
Area = 7.8 * 9.3
Area = 72.54 Do your rounding at the end.
Now find the are of the triangle that has been cut out.
The height = 3
The base = 7.8
Area = 1/2 b * h
Area = 1/2 7.8 * 3
Area = 11.7
The area of the figure = area of the rectangle - the triangle's area
Figure Area = 72.54 - 11.7
Figure Area = 60.84
Steps
1. Do long division so 16 on out and 3744 on inside
2. Find how many 16s go in 37 only 1 so 16 under 37 add two 0s and and on the outside on the side it's 100.
3. Then u subtract 3700 from 1600 and get 2144
4. Then only one 16 goes in 21 so it's another hundred and then subtract 2144 from 1600 and get 544.
5. Then find how many 16 go into 54 only 3 then add a 0 on the 3 and after subtraction get 480 after that subtract 544 from 480 and get 64
6. four 16 go into 64 and then u get 234 as a answer
