(b - 3x) + (-5b + 6x - 5)
= b - 3x - 5b + 6x - 5
= b - 5b - 3x + 6x - 5
= -4b + 3x - 5
Answer: b) 160 c) 1500
Step-by-step explanation: b) 50 + 50 + 30 + 30 = 160 c) 50 x 30 = 1500
Okay. So, she buoyant 5.65 lbs of roast beef for $4.50. Multiply both of those numbers to get 25.425 or 25.43 when rounded to the nearest hundredth. So the total cost was $25.43. However, we now have to divide the amount by 6.5. 25.43/6.5 is 3.912 and other odd numbers or 3.91 when rounded to the nearest hundredth. The cost per sandwich was $3.91.
First you have to find the slope, the slope formula is m = y2 - y1/ x2 - x1
m = y2 - y1/ x2 - x1 (-3, 8) (7, 6)
m = 6 - 8/ 7 - (-3)
m = -2/10
m = -1/5
point-slope formula;
y - y1 = m(x - x1) m = -1/5 (-3, 8)
y - 8 = -1/5(x - (-3)
y - 8 = -1/5(x + 3)
so the answer is, B.
hope this helps, God bless!
