Answer:
2
Step-by-step explanation:
2x2-2=2
Answer: 4
<u>Step-by-step explanation:</u>
3(x) : 8
<u> *2 </u>: <u> *2 </u>
= 24 : 16
⇒ 6x = 24
⇒ x = 4
Answer:
w=-7
Step-by-step explanation:
Soooo-
W(x)=-3x-4
divide both sides by x
W=-3-4
combine like terms
W=-7
D+n=25 subtract d from both sides *(if your wondering what d and n are it stands for Dimes and Nickels)* n=25-d
0.10d+0.05= 1.85
0.10d+0.05(25-d)= 1.85
0.10d+1.25-0.05d= 1.85
0.05d = 0.60
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My answer: He has 12 dimes (d=12) and 25-12=13 so 13 nickels.. Hope this helps! :)
