hi <3
lets call the unknown number 'x' for now and form an equation from what we know
1/3(x-9) = 15
now multiply both sides by 3
x - 9 = 45
add 9 to both sides
x = 54
hope this helps :)
Hi there friend:)
Your answer would be to add because 'gain" is the clue word to adding because it means adding on to something or means to have or get more of something added on, so when you add 5 + 0.25 you get 5.25, so 5 + 0.25 =
5.25
Sorry if its wrong
Have A Happy Thanks Giving With Family and Friends
Happy Holidays ^_^

Answer:
x = -5
, y = 1
Step-by-step explanation:
Solve the following system:
{3 x + y = -14 | (equation 1)
-2 x - y = 9 | (equation 2)
Add 2/3 × (equation 1) to equation 2:
{3 x + y = -14 | (equation 1)
0 x - y/3 = (-1)/3 | (equation 2)
Multiply equation 2 by -3:
{3 x + y = -14 | (equation 1)
0 x+y = 1 | (equation 2)
Subtract equation 2 from equation 1:
{3 x+0 y = -15 | (equation 1)
0 x+y = 1 | (equation 2)
Divide equation 1 by 3:
{x+0 y = -5 | (equation 1)
0 x+y = 1 | (equation 2)
Collect results:
Answer: {x = -5
, y = 1
Answer:
a = 60 degrees and b = 30 degrees
Step-by-step explanation:
30 degrees (line E) = angle b
angle b = 30 degrees
there is a right angle plus the 30 degrees = 120 degrees.
180 - 120 = 60 degrees which is angle a
Answer:
x = 1
Step-by-step explanation:
5-7x = 8-4x-6
5-7x = -4x+2
5 = 3x+2
3 = 3x
x = 1
