3².
hope this helps you.
Well if your sum is -18 then you know your answers are going to be negative numbers.
<span>make x be your first unknown negative even integer. you want your negative x and then negative x minus two and negative x minus four </span>
<span>x1= x </span>
<span>x2= x-2 </span>
<span>x3= x-4 </span>
<span>you know all three need to equal -18 </span>
<span>solve for x: </span>
<span>-18= -x + (-x-2) + (-x-4) </span>
<span>-18 = -x-x-2-x-4 </span>
<span>-18+2+4= -3x </span>
<span>12=-3x </span>
<span>12/-3=x </span>
<span>-4=x </span>
<span>then plus x into the first problem. </span>
<span>x1= -4 = -4 </span>
<span>x2= -4-2 = -6 </span>
<span>x3= -4-4 = -8 </span>
<span>so your integers would be -4, -6, and -8 </span>
<span>check: </span>
<span>(-4) + (-6) + (-8) = -18 </span>
<span>let me know if you have any questions. </span>
Answer:the answer is A
Step-by-step explanation:
1/10 plus 8/100
Equals = 9/50
"You" ran faster. 3 1/2 mi. turn into 3 5/10 mile. 1 2/5 mi. turn into 1 4/10 mile. 3/4 of an hour is 45 min. 1/3 of an hour is 20 min. Therefore you multiply 1 4/10 times 2 to get 2 8/10 mi. in 40 min. Since your friend needs 5 more min. to be at the same time as you, you divide 20 (1/3 of an hour) by 4. Which gives you 5 minutes. Now, take the 1 2/5 of the mile. and divide that by 4. Which according to Symbolab.com gives you 1/10. Now go back to the beginning, you ran 3 5/10 mi. in 45 minutes. Your friend ran 2 8/10 in 40 min. Now that we know 5 min. equals 1/10 miles, you can add that to your friend. which means she/he ran 2 9/10 mi. in 45 min. In conclusion, you ran farther that your friend in 45 min. "You" ran faster. (:
