Our given inequality is:
-7x < -42
To solve for the inequality, we need to simplify for x and ensure we've carefully answered the question.
Currently, x is being multiplied by -7.
To get x by itself, we need to perform the opposite of what's being done.
Remember, what you do to one side of an equation/inequality, you must do to the other.
The opposite of multiplying is dividing.
Divide -7x by -7 to get x.
-7x / -7 = x
-42 / -7 = 6 (Dividing a negative by a negative makes a positive, the same goes with multiplying)
You're left with x < 6
When we divide/multiply by a negative, we need to flip the inequality with the opposite value.
Your final inequality is:
x _> 6
I hope this helps you. :)
I’m so sorry i’m doing this i really need help with math and i’m writing this but i think the answer is g=11
Answer: 11.4 m
Step-by-step explanation:
The scenario depicted is that of a right angled triangle with the 7 meters being the base and the 9 meters being the height.
The length of the ladder will therefore be the Hypothenuse.
Using the Pythagorean Rule:
a² + b² = c²
with c being the hypothenuse
7² + 9² = c²
49 + 81 = c²
c²= 130
c = √130
c = 11.4 m
It is 2 12/20 simplified is 2 6/10 simplified is 2 3/5
So if you want it simplified it is 2 6/10 but if you just want the answer I think it would be 2 3/5
Hope this is helpful
And have a great day
He should tell Bill that depending on which side he wants the width or the length on, he should attach another board about 8 feet long to the 7 foot board since that is the length and he shouldnt attach anymore wood to the second board.
