Answer:
The value of x is 47°
and the value of y is 100°
Answer:
y=2x+35
Step-by-step explanation:
so y is what it's equal too so you put y=
then since its $2 every mile you put them next to eachother like
2x so y=2x
then there is just a plain fee of $35 so you add that to the equation which is what makes it look like
y=2x+35
Hope this helps!! :D
Answer:
Actual height of the building is 37.5 feet
Step-by-step explanation:
Formula to be used to get the actual length of the building,
Scale used = 
= 
By this formula,
Actual height of the building = 1.25 × 30
= 37.5 feet

Answer:
The answer is
Speed of the boat in still water= 12mph
Speed of current= 9mph
Step-by-step explanation:
<em>let x= speed of the boat in still water</em>
<em>let y= speed of current</em>
<em></em>
<em>DATA WE HAVE</em>
<em>with current </em>
<em>rate- x+y </em>
<em>time- 6 hours</em>
<em>distance- 126 miles</em>
rate= 126/6= 21
against current
rate- x-y
time- 42hr
distance- 126 miles
126/42= 3
Now, we add these two equations vertically.
<em>x-y=3</em>
<em>+</em>
<em>x+y=21 </em>
<em>2x = 24</em>
<em>Now we divide each side by 2</em>
<em>2x/2 24/2</em>
<em>x= 12</em>
<u><em>The speed of the boat in still water is 12mph</em></u>
<em></em>
<em>NOW WE HAVE HALF OF THE ANSWER</em>
if x+y= 21
then
12+y=21
subtract 12 from both sides
y=9
<em><u>The speed of the current is 9mph</u></em>
<em><u /></em>
<em><u>Checking)</u></em>
<em><u>12+9=?21</u></em>
<em><u>21=21</u></em>
<em><u>12-9=?3</u></em>
<em><u>3=3</u></em>
<em><u /></em>
