Answer:
t= -4
Step-by-step explanation:
t/2-16= -18
first add 16 to both sides
t/2-16+16= -18+16
t/2= -2
now multiply both sides by 2
(t/2)2=-2(2)
t= -4
answer check:
substitute the variable for -4
-4/2-16= -18
-4/2= -2
-2-16= -18
-18= -18
Answer:
234 miles a day
Step-by-step explanation:
<em><u>The whole trip was for 2 weeks (7*2=14 days).</u></em>
<em><u>Since 1 day from each week they took rest, they drove for (14-2(1)=12 days) 12 days.</u></em>
So a total of 2808 for 12 days. The average is 2808 divided by 12 days:
The answer is 234 miles a day
Since we know that <C is congruent to <E, we can say that: A. the two triangles are similar by SAS.
<h3>The properties of similar triangles.</h3>
In Geometry, two triangles are similar when the ratio of their corresponding sides are equal in magnitude and their corresponding angles are congruent.
Ratio = BC/AC = 6/3 = 2.
Ratio = FE/DE = 4/2 = 2.
Thus, the ratio of their corresponding sides are equal in magnitude i.e BC/AC ≡ FE/DE.
Since we know that <C is congruent to <E, we can say that the two triangles are similar by side, angle, side (SAS) criterion.
