Answer:
25+m=h. The missing parts are 45, and 50.
Step-by-step explanation:
Let's gather the information that we have. I started the equation off with 25 minutes as he needs to read for 25 minutes.
He also is going to do a couple of math problems that will take m minutes, so addition will come in.
Altogether, his homework will take him h minutes. As h will be the total, or sum, I put it at the end.
And that is how I got 25+m=h as my equation.
25+15=40, is true! So I know my equation works. Now I can do the same thing to the rest of the questions. It's just simple addition from here.
25+20=45.
25+25=50
25+30=55.
Hope this helped, have a blessed day and for any questions, just ask!
