After solving the equation (work shown in image) your answer would be x > -2. I drew an image of how the number line should look at least similar to, using the solution.
*whenever you divide or multiply with a negative number reverse/flip the sign
< or > signs will always have an open circle
≥ or ≤ signs will have a closed/filled in circle
TIP: To know which way the arrow should point, look at the sign and think of it as an arrow.
< would have the arrow on the number point
this way: <-
or > which would have the arrow on the number line point this way: ->
There are 7000 ones in 7 thousands

Answer:
27
Step-by-step explanation:
To find a percent of a number, change the percent to a decimal and multiply by the number. To change a percent to a decimal, move the decimal point of the percent two places left.

= 0.30 * 90
= 27
Answer:
4
Step-by-step explanation:
(A+B+C+D) / 4 = 10 .... average=sum/number of item
(A+B+C)/3 = 3D ... average of first 3 (A,B,C) is triple of forth (D)
A+B+C = 9D
(9D+D)/4=10
10D = 40
D = 4
