In general it's not "good math" to write "+-". One way to rewrite 300+-50+-75+225 more clearly would be 300 - 50 - 75 + 225.
Working from left to right, 250 - 75 + 225
175 + 225 = 400 (answer)
Answer: 25+x
Explanation: first you must distribute the negative to what is in the parentheses, which in this case is -x. a negative multiplied by a negative is a positive, so you now have 25 + x.
Step-by-step explanation:
Answer:
x>4
Step-by-step explanation:
Use the distributive property to multiply 2 by x−3.
2x−6+5x<9x−14
Combine 2x and 5x to get 7x.
7x−6<9x−14
Subtract 9x from both sides.
7x−6−9x<−14
Combine 7x and −9x to get −2x.
−2x−6<−14
Add 6 to both sides.
−2x<−14+6
Add −14 and 6 to get −8.
−2x<−8
Divide both sides by −2. Since −2 is <0, the inequality direction is changed.
x>-8/-2
Divide −8 by −2 to get 4.
x>4
