First part 3x+(-5)=19 you need to remove parenthesis move the constant -5 to the right to have 3x=19+5 then add those to get 3x=24 then divide to get x=8
The possible side lengths of a triangle are 6cm , 9cm, 17cm
Answer:
Step-by-step explanation:
we know that
when
-------> complementary angles
so
Because
-------> complementary angles
In this problem the product of
is equal to
therefore
When you have a variable in an equation, you have to isolate it on one side. To do this, look for any other numbers and if they are added, multiplied, divided, or subtracted from x.
Next, you take that number and do the opposite of its operation to the other side.
In this example, you have x/5=20
So we first identify that x is being divided by 5
Then we take 5, and do the opposite of division to 20.
So x/5=20 turns into x = 5x20
Then we simplify, x = 100.
If your not sure your answer is write, you can always put the value of x back into the first equation and solve to see if its true:
X/5=20
100/5=20
20=20
Answer:
x = 24
Step-by-step explanation:
8x + 4(4x - 3) = 4(6x + 4) - 4
8x + 16x - 12 = 24x + 16 - 4
24x - 12 = 24x + 12
24x = 24x + 12 + 12
24x = 24x + 24
24x/24x = 24
x = 24
