Answer:
37
Step-by-step explanation:
To find the answer to this equation, we need to substitute 5 into where x is in the original equation.
f(x) = 8x-3
f(5) = 8(5)-3
f(5)= 40-3
f(5)= 37
and that's it! no further simplifying.
0.84 is 10 times as much as 0.084
Answer:
The value of x = 3.
Step-by-step explanation:
The ratio between length and width is given by:

Where:
- L represents the new length
- W represents the new width
Now, we know that each dimension is reduced by x inches, it means:


Then, we will have:

Finally, we just need to solve it for x.




<u>Therefore, the value of </u><u>x = 3.</u>

<span>.99(15) = 1.35x
14.85 = 1.35x
14.85/1.35 = 11
I think it is 15. I am not sure about the proper way to solve this....I just know that if he sold 15 brownies, he could buy 11 packs with exactly no change left over.</span>
A) 25x+15y=650
25x+15(40)=650
Or it could be 25x=650 and 15y=650
B) No because she makes $15 for every necklace which she only has 40 necklaces 15x40=600
