X=34
First add like terms in the equation so that you get the equation 3x-2=100. Next add 2 on both sides so that you then get 3x=102. Lastly divide by 3 on both sides to isolate x. You would then get x=34.
Answer:
c=109.96
Step-by-step explanation:
From the given problem, it says show how to make a ten to solve 13-7.
Subtracting 13 to 7 gets 6. In order to get a 10, subtract 10 by 6. 10-6 = 4.
So, you need to add 4 in order to make a ten.
Disclaimer: What do you by make a ten to solve 13-7?
You can use the Pythagorean theorem for this problem.
a^2 + b^2 = c^2
a^2 + 5^2 = 10^2
a^2 + 25 = 100
a^2 = 75
a = 8.66
h = 8.7
Hope this helps =)
Answer:
324 ft
Step-by-step explanation:
1. We know there are 3 points (A, B, and C)
so far. We also know B is in the middle of A and C.
A----B----C
2. Reading further, post B is 2x as far from C as it is from A.
A----B----.----C
3. Now we know the numeral measurements of the entire stretch going from A to C (486ft).
A----B----.----C
<- 486ft ->
4. How far is point B from C??? Using the info we have, we need to break the total(486) into 3 parts.
A----B----.----C
1 2 3
5. When we divide or break 486 into 3, we get 162 ft. So each of those 3 dividing sections between A B and C are 162ft.
A----B----.----C
162 162 162
6. We know that the dividing section between B and C is double the dividing section between A and B. So, to conclude, you double 162 = 324.
7. Make sure to put it into the correct form to answer (ft) and there you go!
Hope I helped! :))
