Answer:
F. 3 5/6
Step-by-step explanation:
3/5b - 1/2 = 1 4/5
Add 1/2 to both sides. To do this make the 4/5 have a common denominator of 10 by multiplying it by 2/2. Make 1/2 have a common den. of 10 by multiplying it by 5/5.
- 4/5 * 2/2 = 8/10
- 1/2 * 5/5 = 5/10
Now you can add.
3/5b = 1 13/10, which can be simplified to 2 3/10.
To isolate b, divide both sides by 3/5. This is the same as multiplying by 5/3 (reciprocal). First make 2 3/10 an improper fraction.
23/10 * 5/3 = 115/30
Simplified: 3 5/6
Answer:
9
Step-by-step explanation:
13-9= 4
Answer:
The area is the side lengths squared or multiplied by themselves. The three squares have very different areas based on their side lengths. I disagree that a square with 13 inch side length will have area 13. It will have area 13*13=169 square inches.
Step-by-step explanation:
The area of a square is A=s*s.
1st: A = 1*1 = 1 square inches.
2nd: A=1/2*1/2 = 1/4 square inches
3rd: A =2*2 = 4 square inches.
The area of a square with 1 unit side length is still 1. But a square whose side is less than 1 has a very small area and the square whose side length is greater than 1 has a much larger area. The area of a square is the square of its side length or its side length times itself.
Knowing this, a square with side length 13 will not have area 13 but area 169.
Answer:
a= 
or ≈ -3.66
Step-by-step explanation:
-(3a+4)=7
-3a-4=7
<em>Add 4 to both sides</em>
-3a=11
<em>Multiply both sides by -1</em>
3a= -11
Divide both sides by 3
a=
