Answer:
None of these answers are correct.
Step-by-step explanation:
If a²+b²=c², then 7²+5²=c², then if you solve for c this equals about 8. This is none of the answers mentioned which is 8. Also, a good thing to remember is that the hypotenuse is always larger than the two side lengths. So, since the answer is 8 then it is none of the answers.
Answer:
I only know how to solve it, it is -3
Step-by-step explanation:
-8x+3> or = 18-3x
3>or= 5x+18
-15> or = 5x
x>or=-3
Answer: 0.15p+1.59n ≤ 5.00
Step-by-step explanation:
Given: A pencil costs $0.15, and a The notebook costs $1.59.
Let p = Number of pencils.
n = Number of notebooks.
Total cost of pencil and notebook = 0.15p+1.59n
Since Mayumi has $5.00.
So, Total cost of pencil and notebook ≤ $5.00
⇒ 0.15p+1.59n ≤ 5.00
Hence, the required inequality: 0.15p+1.59n ≤ 5.00
X6 – 9x3 + 8 = 0
let u = x^3
u^2 - 9u + 8 = 0
(u-8)(u-1) = 0
u = 1,8
back substitute
1 = x^3
8 = x^3

Answer:
X<1
Step-by-step explanation:
1/2X-3<-2.5
1/2X<-2.5+3
1/2X<0.5
2/1×1/2X<0.5×2/1
X<1
