Answer:
B
Step-by-step explanation:
x - 7y = -21
-7y = -x - 21
y = -x/-7 -21/-7
y = x/7 + 3
Answer:
Rational
Step-by-step explanation:
A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number.
Answer:
Sanchez had 159 hits while Washington had 177 hits.
Step-by-step explanation:
Sanchez: x
Washington: x + 18
We have the equation:
x + (x + 18) = 336
2x + 18 = 336
2x = 318
x = 159
Assuming you are asking
does -2x+y=6 and y-2x=4 have a solution
look at them
rewrite first equation by switching x and y
y-2x=6 and
y-2x=4
false since they are same values
there is no solution
these 2 lines are paralell
NO SOLUTION
