Step-by-step explanation:125÷ 5=25
25*3=75
Answer:
box contains - 3
Step-by-step explanation:
a(x - 3) + 2x = -(x - 5) +4 Remove the brackets on both sides
ax - 3a + 2x = -x + 5 + 4 Subtract 2x from both sides.
ax - 3a + 2x - 2x = -x - 2x + 9
ax - 3a = - 3x + 9
ax - 3(-3) = - 3x + 9
ax + 9 = - 3x + 9
Now if you make a = -3 then both sides with have - 3 for the x coefficient.
Any number could be put in for x and it will make the answer on both sides equal. Notice you could subtract 9 from both sides and it will not change the condition of the problem.
Answer:
Infinite solutions
Step-by-step explanation:
x + y = 10
y = -x + 10
We'll choose one equation to use, x + y = 10
Substitute y with -x + 10
x - x + 10 = 10
x cancels each other out
10 = 10, which would also mean 0 = 0
This means the answer will validate with any number
First find out what 10 percent of 50 is
Do 50/10
I got 5
Then do 5 times 9 to get your answer
You should get 45. Thanks (:
