The expression should be 75+20x. For every nine minutes (75+20(9)) the oven temperature should be at 255 degrees.
A.) For 25 ≤ d ≤ 150;
ΔT/Δd = (5.50 - 5.50)/(150 - 25) = 0/125 = 0
b.) For 25 ≤ d ≤ 75;
ΔT/Δd = (5.10 - 5.50)/(75 - 25) = -0.4/50 = -0.008
c.) For 100 ≤ d ≤ 200;
ΔT/Δd = (6.00 - 5.10)/(200 - 100) = 0.9/100 = 0.009
Answer:
2x + 3x = 17.
$3.40.
Step-by-step explanation:
All the cones cost the same. That means that one ice cream cone will cost x dollars.
She spent $17, with 2 chocolate and 3 vanilla.
2x + 3x = 17
5x = 17
x = 17/5 = 3.4
So, each cone costs $3.40.
Hope this helps!
Answer:
4+5=9
27÷9=3
they sold 3 types of each because if you do 3×5=15 and 3×4=12 and add 12 and 15 you get 27.
