<em><u></u></em>
<em><u>13 and 5</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>Step-by-step explanation:</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>x+y=18</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>x-y=8</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>_____</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>2x=26</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>x=13</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>So the first number must be 13</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>13+y=18</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>y=5</u></em>
<em><u></u></em>
<em><u></u></em>
<u><em>And the second number must be 5</em></u>
Answer:
y=mx+b
m = slope
b = y-intercept
To find slope we use the equation, change in y divided by the change in x. Let's use points (2, 2) and (3, 1).
(2-1) / (2-3) = -1
Meaning our slope is -1 and it will be going down.
Next, we have to find the y-intercept which is the value of y when x=0. When x is 0 y will be 4.
y=-1x+4
The first step is finding how much the metro cost to ride monthly since its a monthly pass. If she rides 16 times for 6.30 every time then you multiply them you should get 100.8. now subtract the original cost before the monthly pass to after. you should get 22.8
Hint: it will help to change all denominators to the same one using gcf or lcm
Answer:
we have 1 cal in 0.2grams (16/80)
so in 100 cal, it is 0.2x100 = 20 grams
