-3(k+7)-5k+4=23
-3k-21-5k+4=23
Get rid of the numbers that aren't being multiplied by k:
-3k-5k=23+21-4
Add like things:
-8k=40
Divide by -8 on both sides to get k by itself and to make the equation even:
k=-5
Answer:
241
Step-by-step explanation:
247+794 is 1041. To find out the number in the blank, do 1041-800, which is 241.
Answer:
4 cannot be the measure of the third side. This is because of the Triangle Inequality Theorem, which states that the sum of two sides of a triangle must be greater than the third side (A+B>C, A+C>B, B+C>A) In this example, if side C were 4, side C (4) plus side A (8) would be 12. Since side B is 12, and 12 cannot be greater than 12, 4 would not work.
Answer=8
Step-by-step explanation:
102+56= 158×2=316+338=654
she spent 654 on rent
71+7=78
y=x/4
78=x-y
plug in
78=x-x/4
78=4x/4-x/4
78=3x/4
312=3x
x=104
he got 104 from mowing the lawn
All the angles add up to 433 degrees
there’s 540 degrees in a pentagon,
540-433= 107,
there’s 180 degrees on a straight line
180-107=73
so angle a is 73 degrees
