Answer:

27, 162, and 127

Step-by-step explanation:

take x plus 6 times the first number x and the third number is (x+100). put it together and you get x+6x+(x+100)=316 combine like terms to get 8x (x+6x+x)+100=316, subtract 100 to both sides. 8x=216 divide by 8 and you get x=27. that's the first number, multiply it by 6 to get 162 which is the second and the third is 27+100 which is 127

Can a triangle have angle measures as 140,43, and 7
Mariulka [41]

The angles in a triangle always add up to exactly 180 degrees.  To see if this can be a triangle, add up the given angle measures.  If the sum is not 180, then it cannot be a triangle.

140+43+7=190

A triangle CANNOT have the angles measures as 140, 43, and 7.

Hope this helps!!

Enter the equation of the circle in standard form with center and radius given.\\\\\\\\\\\Center (8,0), radius = sqrt 3/////////
ehidna [41]

Answer:

 (x - 8)^2 + y^2 = 3.

Step-by-step explanation:

(x - h)^2 + (y - k)^2 = r^2

Here h = 8, k = 0 and r^2 = (√3)^2 = 3

The answer is  (x - 8)^2 + (y - 0)^2 = 3

or (x - 8)^2 + y^2 = 3.

Help??? What is 3x+5x=67y?
ruslelena [56]
All you have to do is combine 3x and 5x to = 8x. You can't combine 8x and 67y because they have different variables. so it's 8x+67y.

Karo-lina-s [1.5K]

Answer:

$39.24

Step-by-step explanation:

Let's determine the sale price before tax:

0.40($60) = $24 is the discount, so

the sale price is $60 - $24, or $36.

Multiplying this result by 1.09 results in the total price, including tax.  It is $39.24.
