Answer:
4x + 4y - 8
Step-by-step explanation:
4(x - 2 +y) = 4*x -4*2 + 4*y by the distributive property
Y= 8/2x + -4 i think is that one
10% i believe :)
i hope this helps u!!
This is a basic algebraic word problem. Make x equal the miles you traveled. multiply that by 2 and add the 3 initial dollars, then add the one dollar tip, finally make all this equal to 20. So your equation should look like this:
2x + 3 + 1 = 20
add the 3 and 1:
2x + 4 =20
move the 4 to the right side:
2x = 16
devide both sides by 2:
x = 8
So you traveled 8 miles.
19n-57=76
You must get "n" by itself
19n-57+57=76+57 (add 57 to each side)
19n=133
Divide 133 by 19
133÷19=7
n=7
