what is 1/4+3/8 in simplest form? explain.

1. 1

2. 5/8

3. 3/4

4. 7/8

5. 5/8

Step-by-step explanation:

1. The denominators are the same, so just add the top numbers (the numerator), 1/7 + 6/7 = 7/7, which is 1.

2. The denominators are the same, so just add the top numbers (the numerator), 7/16+3/16=10/16. 10/16 can be divided by 2 to get 5/8.

3. 1/6=2/12. So, the new problem is 2/12+7/12. Add the numbers, and you get 9/12. Divide the top and bottom by 3, and your answer is 3/4.

4. 3/4=6/8. The new problem is 6/8+1/8. This is 7/8.

5. 1/4=2/8. The new problem is 2/8+3/8. 2+3 is 5, so your answer is 5/8.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

the radius is 2 times the diameter.
