72+28+66+81=297
360-297=63
She would need to score 63 on her last exam.
Answer:
2x − 3y = 9 2 x - 3 y = 9 The slope-intercept form is y = mx+ b y = m x + b, where m m is the slope and b b is the y-intercept. y = mx +b y = m x + b Rewrite in slope-intercept form.
Step-by-step explanation:
answer is y = 2/3x-3
Answer:
x=-2
Step-by-step explanation:
14+6x=2
Then u move 14 to the other side since it doesn't have a a variable and 2 doesnt also there both just numbers so 14 moved to the otehr side will be -14 so 6x=2-14
6x=-12
x=-12/6=-2
To solve 4n you need to divide both sides by 4
