Carmen is serving her child french fries and chicken wings for lunch today. Let f be the number of french fries in the lunch, and let c be the number of chicken wings. Each french fry has 25 calories, and each chicken wing has 100 calories. Carmen wants the total calorie count from the french fries and chicken wings to be at most 700 calories. Using the values and variables given, write an inequality describing this.

25f+100c≤700

Step-by-step explanation:

Let f be the number of French fries in the lunch

Let c be the number of chicken wings.

Each French fry has 25 calories.

Therefore, Calories from French fry

= Number of French Fry X Calories from French Fry = 25f

Each chicken wing has 100 calories.

Therefore, Calories from chicken wing

= Number of chicken wings X Calories from Chicken wings = 100c

Since Carmen wants the total Calories to be at most 700 calories, therefore, the sum:

25f+100c≤700

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

answer: -1
