Answer:
$598.12.
Step-by-step explanation:
First you need to make the percent into a decimal and multiply it by the price without tax: 0.0975 · 544.98, which equals 53.136 when rounded to the nearest thousandth. This means that 53.136 is 9.75% of 544.98. Then you just need to add 53.136, or 53.14 when rounded, to 544.98. This gives you $598.12.

Which of the following number lines represents the solution to m/-2 - 7 = -9?
Answer:
Step-by-step explanation:
the answer is a. (the first one)
Number lines are used to represent relationship between numbers at regular intervals
The number line that represents the equation [tex]\frac{m}{-2} - 7 = -9[/tex] is number line (c)
The equation is given as:
[tex]\frac{m}{-2} - 7 = -9[/tex]
Add 7 to both sides of the equation
[tex]\frac{m}{-2} = -2[/tex]
Multiply both sides of the equations by -2
[tex]m = 4[/tex]
This means that, the solution to the equation is [tex]m = 4[/tex]
The number line that represents [tex]m = 4[/tex] is number line (c)

Answer:
x = 33
Step-by-step explanation:
This picture shows a supplementary angle which means:
angle 1 + angle 2 = 180°
In order to solve for x, you need to add both the angles
(2x + 1) + (4x - 19) = 180° start by simplifying this equation by adding like terms
6x - 18 = 180° you can solve this like a regular inequality now, add 18 to 180°
6x = 198 now divide 6 by 162
x = 33

I only know + I don’t know - pls helpp!!
Answer:
x=31
Step-by-step explanation:
Since these angles are on a straight line, they are supplementary (combine to make 180 degrees. Therefore we can set up an equation to find x.
(5x-16)+(x+10)=180
Drop the parentheses.
5x-16+x+10=180
Combine like terms.
6x-6=180
Add 6 to both sides.
6x=186
Divide both sides by 6.
x=31
