Answer:

Step-by-step explanation:
Remember that it doesn't matter how many numbers are after the tenths place of a decimal point what matters is the tenths place itself. If you have a decimal that has dozens of numbers but it's tenth place is a 3 and then you have a decimal with 5 numbers in whole but it's tenths place is 4, the 4 is greater then the 3 simply because it's greater in tenths.
Hope this helps.
2(9x + 3) + 5x = 48 + 2x
18x + 6 + 5x = 48 + 2x
23x + 6 = 48 + 2x
23x - 2x = 48 - 6
21x = 42
x = 42/21
x = 2
Your coordinates are (x,y), here you just need to figure what 'x' is given that 'y' is equal to -3. So, just plug in -3 for 'y' in the equation and then solve for 'x', like so: 4x + 5(-3) = -7 ... then just use algebra to solve for what 'x' has to be. Hope this helps!
Answer:
45°
Step-by-step explanation:
<u>The Supplementary Angles Postulate states that if two angles form a linear pair, then the sum of the angles is 180°.</u>
<u />
With this knowledge, you can set up your equation:
(3x+6)+(x+2)=180
<em>(It's okay that I didn't put the degrees in, you still get the same answer)</em>
<em>First, combine like terms.</em>
(<u>3x</u>+6)+(<u>x</u>+2)=180
4x+<u>6</u>+<u>2</u>=180
4x+8=180
<em>Then solve.</em>
4x+8=180
-8 -8
4x=172
÷4 ÷4
x=43
<em><u>DO NOT STOP HERE!! Since the question asks for the measure of angle SQR, do NOT put 43 as the answer!! It is a common mistake (I have fallen for it many times before!!)</u></em>
<em>Plug in the "x" into the equation.</em>
(43)+2=45°
