Team D's car went the same distance on each of its trials. Team C's car went exactly 1 cm farther in each trial than Team D's ca
mezya [45]

Answer:

180 cm

Step-by-step explanation:

Number of trials per team = 3

Distance per trial for team D's car is the same for each trial, let distance = x

Distance per trial for team C's car is 1cm farther than team D's distance and the same for each trial, hence, distance = x + 1 per trial

Total distance traveled by C = 543 cm

This means :

(x + 1) + (x + 1) + (x + 1) = 543

3x + 3 = 543

3x = 543 - 3

3x = 540

x = 540 / 3

x = 180

Hence, distance traveled per trial for team D's car = x = 180 cm

Lia is cooking.She needs 2 3/4 cups of flour and 4 3/4 cups of cornmeal.Lia wants to bake sure she has a bowl big enough to hold
Sholpan [36]

Answer:

Lia needs 7\frac{2}{4}\ cups of flour and corn meal.

Step-by-step explanation:

Given:

Amount of flour needed = 2\frac{3}{4} \ cups

2\frac{3}{4} \ cups can be Rewritten as \frac{11}{4}\ cups

Amount of flour needed =  \frac{11}{4}\ cups

Amount of Corn meal needed = 4\frac{3}{4}\ cups

4\frac{3}{4}\ cups can be Rewritten as \frac{19}{4}\ cups

Amount of Corn meal needed =  \frac{19}{4}\ cups

We need to find the total amount of of flour and cornmeal she needs.

Solution:

Now we can say that;

the total amount of of flour and cornmeal she needs is equal to sum of Amount of flour needed and Amount of Corn meal needed.

framing in equation form we get;

the total amount of of flour and cornmeal she needs = \frac{11}{4}+\frac{19}{4}=\frac{11+19}{4}=\frac{30}{4}\ cups\ \ OR\ \ 7\frac{2}{4}\ cups

Since Answers are not given:

Kindly chose the answer which contains below data.

Hence Lia needs 7\frac{2}{4}\ cups of flour and corn meal.
