PLEASE HELP ME WITH MY MATH!!!!
1 and 2 are right.
Please check for a typo in 3. None of the answers is the solution for the problem.
i will check and thank you so much
You are very welcome.
Sure! I'll help you with your math problems one by one.
1. To solve for the variable in the equation x + 1/2 = 1 1/2, we need to isolate x.
- First, subtract 1/2 from both sides of the equation: x + 1/2 - 1/2 = 1 1/2 - 1/2
- This simplifies to: x = 1
- So, the solution for x is 1.
2. To solve for the variable in the equation 10/13n = -30/39, we need to isolate n.
- Multiply both sides of the equation by the reciprocal of 10/13, which is 13/10: (10/13n) * (13/10) = (-30/39) * (13/10)
- This simplifies to: n = -39/13
- So, the solution for n is -39/13.
3. To solve for the variable in the equation k - 3/4 = 10, we need to isolate k.
- Add 3/4 to both sides of the equation: k - 3/4 + 3/4 = 10 + 3/4
- This simplifies to: k = 10 + 3/4
- To add 10 and 3/4, we need to find a common denominator. The denominator of 10 is 1, and the denominator of 3/4 is 4. So, the common denominator is 4.
- Convert 10 into an equivalent fraction with a denominator of 4: 10 * 4/4 = 40/4
- Now add the fractions: 40/4 + 3/4 = 43/4
- So, the solution for k is 43/4, which can also be written as 10 3/4 or 5.5.
