Answer:
x=1
Step-by-step explanation:
You need to add the Numbers with an x together as if they were racist on each side so you'd have
4x+2 = x+5
Then to move them to either side you must do the opposite symbol of what they are so if their positive their now negative
4x-x=-2+5
then add them together
3x= 3
then divide the normal number with the number with the x
x=1
For the next problem you Multiply thr number that are in the paranthases by the number on the outside so
6-x-3 = 4(x-2)
6-x-3= 4x-8
then copy the steps that I told you from last problem
-9-x=4x-8
then
-9+8=x+4x
thenn
-1=5x
divide
0.2-=X
Answer: The correct option is the third one. Angle 1 and Angle 2 are adjacent angles.
Step-by-step explanation: A brief explanation of Supplementary angles, Complementary angles, Equivalent angles and Adjacent angles would be very useful in answering this question.
Adjacent angles are two angles that are formed when a line cuts a vertex, thereby causing both angles newly formed to have the same vertex, and the same side(s). A vertex is the endpoint that is formed when two lines meet and form an angle. Both angles 1 and 2 do not have to two equal halves, but it is sufficient that they both are formed in the same vertex and they share the same side(s).
Supplementary angles are two angles that add up to 180 degrees. This is mostly found on straight lines, when another line cuts through the straight line, both angles formed are supplementary (angles on a straight line equals 180 degrees).
Two angles are called complementary when they both add up to 90 degrees. This is mostly observed in a right angled triangle, where one angle is always equal to 90 degrees then the other two angles must add up to 90 degrees and they are described as complementary (sum of angles in a triangle is equal to 180). The angles do not necessarily have to be next to each other (although sometimes they are next to each other). The question does not tell if the angle ABD is a right angle, so we cannot tell for sure that angle 1 and angle 2 are complementary.
Equivalent angles as the name implies are two angles that have the same measurement. This is more applicable to angles in different plane shapes (for instance angles in two congruent triangles). This does not apply to the description of the angles as stated in the question.
Answer:
If 20 more soldiers join it would last 48 days
Step-by-step explanation:
if 80 soldiers need 84000 food for 60 days it means that in 60 days one soldier eats 84000/80= 1050 each
then 1050/60=17.5 meaning they need 17.5 food a day each,
adding 20 soldiers means 80+20= 100 soldiers
100*17.5=1750 food is eaten every day
84000/1750= 48 which means that 100 soldiers will eat 84000 in 48 days
The answer to this would be A: -9/10. Hope this helps!
