First move the -8 on the left to the right. this makes the inequality become 8x≤-64. Then you want to isolate the x by dividing 8x by 8, and make sure to do the same to -64. This makes it become x<span>≤-8, which is your final answer! Hope this helped :)</span>
X(7 - x) > 8
First solve x(7 - x) = 8
x^2 - 7x + 8 = 0
x = 5.56, 1.44
If we plug in these values into the original equation weel see that solution is
1.44 < x < 5.56
Answer:
-4x-13
Step-by-step explanation:
To figure out the sum, you have to add like terms.
This is how it would look like:
Answer:
40 square units
Step-by-step explanation:
The surface area is given by
LA = 2(wh+lh)
where h is the height l is the length and w is the width
We do not include the top or bottom
We know l=6 w=4 and h=2
LA = 2 ( 4*2 + 6*2)
lA = 2( 8+12)
= 2 (20)
= 40
First, you add the two parts of the ratio together. 8+5=13. Then you do 390 divided by 13 which is 30. After this, you multiply 30 by each side to get the ratio to be equal. 30x8=240, and 30x5=150. This can now be put into the ratio 240:150. As you said it was in the ratio adults to children, it must stay in that order. The part of the ratio for children is 150.
<em>The answer to your question is 150. You can double-check your answer by adding up the two parts again. 240=150=390 so you can be assured that your answer is truly correct. Thank you for uploading this question. I hope my explanation was helpful enough for you
