Let's call the unknown amount of money <em>x</em>
Betty spend 5/12 of her money (5/12)x and had 42 dollars left. Translated,

Solving,



Answer: $72
We can use the slope-intercept form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept.
From the graph, we see the line crosses the y-axis at y = 15. That means the y-intercept is 15, and we have so far y = mx + 15.
Now we need the slope. On the graph we see that for every 3 units up in y, there is 1 unit to the right in x. The slope is 3/1 = 3. m = 3. Now we add the slope to the equation.
y = 3x + 15
Answer: y = 3x + 15
Answer:
CB=18
And the measure of angle BDA is 21 degrees
Step-by-step explanation:
Id multiply the numbers and take the square root X<span>2=96×6=576</span><span>→X=<span>576<span>−−−</span>√</span>→X=24</span>Hence Geometric mean of the given numbers is 24.
Answer:

Step-by-step explanation:
we have
---> First equation
--->Second equation
we know that
To subtract the 2nd equation from the first, negate all three of the second equation terms: -7x-8y=6
and then adds this result with the first equation
so
