Answer:
5) x=10
6) x=7
7) x=3
8) x=12
Step-by-step explanation:
5) 19=2x-1
19+1=2x
20=2x
x=10
6) 3x-6=15
3x=21
x=7
7)10=2x+4
10-4=2x
6=2x
x=3
8) x+3=2x-9
3=x-9
x=12
Step-by-step explanation:

Answer:
8. A
First step is to distribute - to 6x and 3. Next u want to combine like terms. So 2x^2-6x^2 = -4x^2. Next 4x - 6x = -2x. Again 9 + 3 = 12. Combine and u get -4x ^2 - 2x +12
9. C
First you add 4x to both sides. Then you subtract 55 leaving -45 greater than or equal to 9x. Then you divide by nine and you get -5 is greater than or equal to x
10. B
First you distribute 5 so 15 -3x < -2x +6. Next add 2 to both sides. Then subtract 15 leaving -3x < -9. Least divide by -3 and you get x > 3(the sign was swapped bc dividing by a negative number means it has to)
11. B
For this you could just distribute the equations and we on that 7•4=28. And 7•5=35. I'm this case both of the numbers have to be negative so 7 has to be negative as well
12. C
Distribute -2/3 and you get 9q^2-2q+14/3+5q^2
Then combine like terms and 9q^2+5q^2=14q^2. Order them and ur answer is 14q^2-2q+14/3
In the problem, how do you get 6,300,000 using the digits 1-7 to create a
seven-digit number that can be rounded to 6,300,000.
We can use the numbers according to the rule of rounding values, 0-4 and
5-9.
Hence the numbers are:
1. 6, 290,000 = 6, 300, 000
2. 6, 310, 000 = 6, 300, 000
Therefore the numbers concerned in the given value is in the place order of
ten thousand which will determine the hundred thousands’ value.
