Answer:
600
Step-by-step explanation:
Given,
Numbers are 825 and 213.
If the number are equal or greater than 50 then one number will be rounded up. if the number is less then it will rounded down.
Like in this case 25 and 13 are less than 50 so, they will not rounded up.
825 will be rounded to 800.
213 will be rounded to 200.
Subtraction of number
= 800 - 200 = 600
Answer:
Step-by-step explanation:
<u>27.</u> the sum of 2 complementary angles=90
8x-17+5x-10=90
13x=90+27
13x=117 <u>x=9 </u>
<u>28. </u> the sum of supplementary angles=180
17x-12+3x-48=180
20x=180+60
20x=240
<u>x=120</u>
400 = 45x + 30x
400 = 75x
5.333 = x
Lets test
45mph for 5.333 hours = 240 miles
30mph for 5.333 hours = 160 miles
240 + 160 = 400 miles apart.
