Answer: 12 h + 135
Step-by-step explanation: 7h +135 + 5h = ?h + ?
7h +5h +135
=12h +135
So u combine like terms together which are 7h and 5h which gives you 12 h.And then you have 135 left,so you add 12h to 135.
Ps.If you don't know what like terms are.I will explain down below.
Like terms are variable that are the same.For an example 4y and 3y are like terms .Another example is 1/3 xy and 6xy .
Hope this helps :) and if it does please give brainliest .
5x>/ 45
at least means it can be 45 and up
So it becomes greater than or equal to
Answer:
1. U. 190
2.U. 155
3. U. 240
Step-by-step explanation:
Explanation: To find an angle of a triangle we add the angles we know about
EXAMPLE: 50 + 120. We need to find the third angle.
We know that Angles of triangles should add up to 360
So to find the third angle we add the angle we know about.
EXAMPLE: 50 + 120 = 170 then we Subtract the sum of a triangle *360*
EXAMPLE: 50 + 120 = 170
EXAMPLE: 170 - 360
EXAMPLE: = 190
That's how we find a third angle!
If this doesn't clarify how do to it enough just let me know and i can try to explain more in detail!
Hope this helps you!!!
Have a nice day!
Answer:
y=23x+4
Step-by-step explanation:
Answer:
{-2,10}
Step-by-step explanation:
x^2 - 8x = 20
Take the coefficient of x
-8
Divide by 2
-8/2 =-4
Square it
(-4)^2 =16
Add this to each side
x^2 - 8x+16 = 20+16
x^2 - 8x+16 = 36
The left hand side becomes( x + (-8/2) )^2
(x - 4)^2 = 36
Take the square root of each side
sqrt((x - 4)^2) =±sqrt( 36)
x-4 = ±6
Add 4 to each side
x-4+4 = 4±6
x = 4±6
x = 4+6 x = 4-6
x = 10 x = -2
