Answer:
<h2>
</h2><h2><u><em>
the equation is false</em></u></h2>
<u><em></em></u>
Step-by-step explanation:
x - 10+ 9x = - 1 + 10x
-10 + 1 = -x - 9x + 10x
-9 = 0
the equation is false
Answer:
3) x = 15; 95 and 85 4) x = 12; 98 for both angles
Step-by-step explanation:
2x + 65 + 3x + 40 = 180 Set the equations equal to 180
5x + 105 = 180 Combine like terms
- 105 - 105 Subtract 105 from both sides
5x = 75 Divide both sides by 5
x = 15
Plug 15 into both equations
2(15) + 65 = 95
3(15) + 40 = 85
4) 5x + 38 = 9x - 10 Set the equations equal to each other
- 5x - 5x Subtract 5x from both sides
38 = 4x - 10
+ 10 + 10 Add 10 to both sides
48 = 4x Divide both sides by 4
12 = x
Plug 12 into both equations
5(12) + 38 = 98
9(12) - 10 = 98
Let X be the total number of guests
when X =1
(17+828)/36
845/36=23.5
am sorry but the question is not that clear
pls mark as brainliest
Consider the number 480 in expanded form:
... 480 = 4×100 + 8×10
The left-most digit and multiplier are those that correspond to the ones you use in scientific notation.. You recall that 100 = 10×10 = 10². All this means is that
... 480 = 4.8×10²
