Use a calculator.
14.1 divided by 2.35 = 6
For simplicity sake, let's call Train A "A" and Train B "B".
A + B = 192
A > B
A - B = 120
192 ÷ 2 = 96
96 ± 120 ÷ 2 = 96 ± 60 = 156, 36
Train A weighs 156 tons and Train B weighs 36 tons :)
Answer:
C(x)=0.65x+8
Step-by-step explanation:
According to the information given, you can say that the total cost would be equal to the result of multiplying the cost of the meat and bun per burger for the number of burgers made plus the amount spent on condiments and supplies, which can be expressed as:
C(x)=0.65x+8, where:
C(x) is the total cost
x is the number of burgers made
slope-intercept form is y = mx + b
3x - 7y = 35
<u> -3x -3x
</u> -7y = -3x + 35 (divide each side by -7)
y = -3/-7x + 35/-7
y = 3/7x - 5
Answer:
x=18
Step-by-step explanation:
3(x-4)=2x+6
3x-12=2x+6
3x-2x=6+12
x=18
