Answer:
x < 2
Step-by-step explanation:
8x -1 < 15
8x -1 (+ 1) < 15 (+ 1)
8x < 16
x < 2
Ok, so you knnow that for angles to be supplement, they need to equal 180 degrees. So you can create an equation as follows:
(3 times X minus 12) degrees plus (x)degrees equals 180 degrees
(3x-12) + (x)=180
4x-12=180
4x=192
x=48
So now you plug in "x=48" into this equation (3x-12) to find the measure of the angle.
And if I did the math correctly, the answer should be "132" degrees.
Answer:
The amount Chris started within his savings is $44. option C
Step-by-step explanation:
Amount Chris saved = $xAmount spent on video games = 1/2xAdditional amount earned = $10Total = $321/2x + 10 = 32subtract 10 from both sides1/2x = 32 - 101/2x = 22divide both sides by 1/2x = 22 ÷ 1/2x = 22 × 2/1x = $44Therefore, the amount Chris started within his savings is $44. option C
Hope this helped !!!!
Answer:
400
Step-by-step explanation:
The computation of the sample size needed is shown below:
Since at the sample size of 200 there is a standard deviation of 0.08
But when the standard deviation is 0.04 so the sample size is 400
As sample standard deviation would be inversely proportional to the square root of the sample size
I believe it’s D not 100% sure but yea
