To make it easier, we’ll solve for x, as you do.
To get rid of 3, add 3 to both sides.
5x < 15
Now divide by 5.
x < 3
x is less than 3.
Some integers that satisfy this equation are:
2, 2.9, -10, and anything else below the number 3.
Answer: SECOND OPTION
Step-by-step explanation:
You can solve the system of equations by the method of substitution:
- You must susbtitute the second equation into the first equation and solve or x:
- Now, you must susbtitute the value of x obtained above into the second equation to calculate the value of y. Then, you have:
Therefore, you obtain:

Answer:
a. 10
b. -4
Step-by-step explanation:
For these problems, since we are given the x, we plug it into the expression and solve.
a.
3(4)-2 [multiply]
12-2 [subtract]
10
-------------------------------------------------------------------------------------------------------
b.
5(-2)+6 [multiply]
-10+6 [subtract]
-4
3,000 in.
(4 x 10) + (7.5 x 10) = 3000
The dimensions on the sketch are 10 times less than the actual rug.
40 in., 7.5 in.
The drawing lengths are ten times more, so you just multiply the dimensions by 10, and then multiply the product you find out to find the actual area of the rug.
(x + 9)(x + 12) = 0
Expanding the brackets, we get:
