Answer:
31.5
Step-by-step explanation:
Ok.
2/3x - 9 = 12
2/3x = 21
x = 21*(3/2)
x = 63/2 = 31.5
you have $32
you can't spend more than that but you can spend less if you want, or you can spend exactly the amount you have.
the total cost will depend on how many cassettes you buy and how many CDs you buy
knowing this information, you can set up the inequality:
32 ≥ 5x + 9y
hope this helped
Answer:
Approximately 6.4
Step-by-step explanation:
We can use the pythagorean thereom here, that tells us (a^2)+(b^2)=c^2. C is the hypotenuse, the side opposite from the right angle, while a and b are the other sides. We can insert 5 and 4 as a and b, and solve for c
:(5^2)+(4^2)=c^2
:25+16=c^2
:41=c^2
:sqrt(41)=6.4=c (We square rooted both sides. 6.4 is only rounded to the nearest hundredths place.) Hope this helps!
Answer:
-151
Step-by-step explanation:
first find the value of g(6)
g(6) = -3 × 6 - 8 ➡-24
then put this value fir f(g(6))
f(-24) = 6 × -24 -7 ➡ -151
