Answer:
x ≥-3
Step-by-step explanation:
7 − 9x − (x + 12) less than or equal to 25
7 − 9x − (x + 12) ≤ 25
Distribute the minus sign
7 − 9x − x - 12 ≤ 25
Combine like terms
− 10x −5 ≤ 25
Add 5 to each side
− 10x −5+5 ≤ 25+5
− 10x ≤ 30
Divide by -10. Remember that this flips the inequality
− 10x/-10 ≥30/-10
x ≥-3
Answer:
x = -3
Step-by-step explanation:
-5x + 32 = 47
-5x + 32 - 32 = 47 - 32
-5x = 15
-5x / -5 = 15 / -5
x = -3
Answer:
4a) The sides are not scaled up equally for the sides. Plus, B is not a right triangle since it does not satisfy the pythogorean theorem.
4b) 6, 8, 10
SO you would have to first have the surface area of the cube which is 25 for each side so 25 x 6 = 150
Then you find the surface area for the other sides and It is 4 x 5 divided by two for each triangle on the side, so that would be 20 and you multiply then 6.4 x 5 to equal 32 for the rectangle. The last part is the bottom and it is 4 x 5 again which is 20 so then you add them all up but im not sure.
26/44 - 18/44 = 8/44
26 - 18 = 8
even though it is subtraction, you do not subtract the bottom numbers (denominator).
so your answer is 8/44
if you simplify it, you will get 4/22 and then 2/11
your simplified answer is 2/11 (is this on there?)
hope this helps
