Yan has already finished 3/5 of the 45 math problems he was assigned today. Each math problem took him 1 4/5 of a minute to comp

kobusy [5.1K]

Answer:

He will finish the rest of the problems in 32.4 minutes.

Step-by-step explanation:

Since we are given that Yan has completed 3/5 of 45 problems i.e.

$\frac{3}{5}*45$

$27$

Thus he has completed 27 problems

Remaining no. of problems are 45-27 = 18

Since he complete each problem in minutes = $1\frac{4}{5} =\frac{9}{5} =1.8$

So, he completes 18 problems in minutes = 18 *1.8 = 32.4 minutes

Hence , He will finish the rest of the problems in 32.4 minutes.

Find the value of x<br> (9x-38)+(4x+23)=180

kondor19780726 [428]

Answer:

x=15

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

9x−38+4x+23=180

9x+−38+4x+23=180

(9x+4x)+(−38+23)=180(Combine Like Terms)

13x+−15=180

13x−15=180

Step 2: Add 15 to both sides.

13x−15+15=180+15

13x=195

Step 3: Divide both sides by 13.

13x/13=195/13
