Answer
(10x+15) + (5x)=180
X=11
Answer:
Step-by-step explanation:
x + 0.05x = 36225
x(1 + 0.05) = 36225
x*1.05 = 36225
by solving we find:
x = $34,500
Answer:
<h2>A) y= -x + 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line<em>:</em>
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
==========================================
We have the points (-1, 2) and (4, -3).
Calculate the slope:
Put the value of the slope an the coordinates of the point 9-1, 2) to the equation of a line:
<em>subtract 1 from both sides</em>
Finally:
Answer:
-221 base 3
Step-by-step explanation:
We are to calculate the value of the numbers in base 3. One of the ways to do that is to first convert each number to base 10. Do the arithmetic, then convert back to base 3.
121 base 3 +2122 base 3 - 1200 base 3 - 2111 base 3
Let's convert to base10
See attachment for details
From the workings,
121 base 3 + 2122 base 3 - 1200 base 3 - 2111 base 3 = -221 base 3
