Answer is in fractions 79/24 and in decimals it is 5.642857143
Answer:
y = -0.25*x + 2
Step-by-step explanation:
y = a*x + b
is perpendicular to the line 4x+y=3 -> a = -1/4 = -0.25
y = -0.25*x + b
b = y + 0.25*x = -3 + 0.25*4 = -2
y = -0.25*x + 2
Answer: Small box: $13; Large box: $16
Explanation:
Make two individual equations for Perry and Alberto. Perry's equation would be 7x+12y=283. Alberto's equation would be 8x+6y=200. The best way to find the variables is to change the equations into slope-intercept form. Perry's equation would change to y=-7/12x+283/12 and Albert's equation would change to y=-4/3x+100/3. You can try substituting and plugging -4/3x+100/3 into the other equation, so they equal each other. But, you can also just graph the equation into a graphing calculator or Desmos. When graphing it, the point of intersection should be (13,16), so the cost of a small box tangerines is $13 and a large box of tangerines is $16.
Answer:
n = 1/22
Step-by-step explanation:
[2/5 (8 + 2 · 6)] ÷ 2n = 88
2/5( 8 + 12) ÷ 2n = 88
2/5( 20) ÷ 2n = 88
8 ÷ 2n = 88
= 88
4 = 88n
n = 4/88 or 1/22
