10 and 10 (when both are rounded to the nearest 10th)
First, square both sides of equation so it ends up to be:
a/6=81
so
a=27/2

Answer:
3
Step-by-step explanation:
Let x represent the number. The problem statement tells you ...
2/3(3x +6) = 10
2x +4 = 10 . . . . . . use the distributive property
x +2 = 5 . . . . . . . . divide by 2
x = 3 . . . . . . . . . . .subtract 3
The number is 3.

<em>Comment on the solution</em>
The above shows an "alternative" solution method. The more usual way this might be done is ...
2(3x +6) = 30 . . . . . multiply by 3 to clear fractions
6x +12 = 30 . . . . . . . eliminate parentheses
6x = 18 . . . . . . . . . . . subtract 12
x = 3 . . . . . . . . . . . . divide by 6
Answer:
Step-by-step explanation:
the answer is
$194 (start) / <u>100 (100%)</u> = $1.94 (1%)
$1.94 * 7 = $13.58 (7%)
$13.58 * <u>13 (13 years)</u> <em>= $176.54 </em>
$194 (start) + <u>$176.54 (interest)</u> <em>= $370.54</em>
Answer: See below
Step-by-step explanation:
For the line on top, we know the slope is negative because it is going down. We can find the slope by counting how much the point goes down and to the right. Y-intercept is the point on the y-axis.
slope: -3
y-intercept: 2
Now that we have the slope and y-intercept, we know the equation is y=-3x+2.
For the second line, we know the slope is positive because it is going up. Since slope is rise/run, we can see it rises 1 unit and runs to the right by 2 units. Y-intercept is the point on the y-axis.
slope: 1/2
y-intercept: -5
With our slope and y-intercept, we know our equation.
y=1/2x-5
