3x - 9x + 7 - 3 = -8
-6x +4 =-8
-6x = -12
Divide that by -6
x = 2
The answer is D (i have to type at least 20 letters soooooooooo)
Answer:
30
Step-by-step explanation:
12×5=60 60÷1/2=30
srry if I was wrong
P: 90-34/3 = 18.67 or 18.7 or 19
r: 76-44/2 = 16
s: 1421-53/6 = 228
Hope this helps!
3. <u>Two angles and included side (ASA congruence theorem)</u>.
<u>Reason:</u> This is because, it is given that angle Q is congruent to angle T and line QR is congruent to line TR. Also, we proved in step 2 that
. Thus, we have two angles and the side included as congruent and thus, the two triangles are congruent.
4. <u>CSCT (Corresponding Sides of a Congruent Triangle)</u>
<u>Reason:</u> PR and SR are the corresponding sides of the congruent triangles
and
, therefore, by the CSCT these corresponding sides have to be congruent.
