In two hours Holden completed 3/4 of his race how long will it take Holden to complete the entire race?
vivado [14]

Answer:

\frac{1}{4} = 50 Minutes

Whole Race Time : 2 Hour and 50 Minutes

Step-by-step explanation:

so 2 Hour = \frac{3}{4} Race completed

we need to find what 1/4 Race = x Hours

so 200 divided by 4 because \frac{3}{4} Race is done.

we need to find how long to finish the whole race also known as \frac{4}{4}.

200 divided by 4 = 50

so Holden still need 50 Minutes to finish the race.

3(x-1) = 2x - y

3x-3 = 2x-y

3x-2x+y = 3

x + y = 3 ----> (1)

2(x+y) = 3+3y

2x + 2y = 3 + 3y

2x + 2y - 3y = 3

2x - y = 3 -----> (2)

make equation (1) and (2) together

x + y + 2x - y = 3+3

3x = 6

x = 2

now make x = 2 in equation (1)

x + y = 3

2 + y = 3

y = 3-2

y = 1



(x,y) = (2,1)

17. The letter is J

The letter appears 3 times

18. Lefthanded students = 4 students

<h3>How to determine the factors</h3>

17. We have that 1/4 of the months of the year start with the same letter

It is important to note that:

January, June and July all start with the same letter

The letter is J

The letter appears 3 times

18. Total number of students = 24

5/ 6 are right handed

Right handed students = 24 × 5/ 6 = 4 × 5 = 20 students

Lefthanded students = 24 - righthanded students

Lefthanded students = 24 - 20

Lefthanded students = 4 students

Thus, we can see that the letter that appear in 3 months of the year is J
