Answer:</h2>
<u>The length is</u><u> 250 meters</u>
<h2>
Step-by-step explanation:</h2>
If we look at the left corner of the diagram we see a scale. According to the scale factor of the map
1 cm :1000 cm
The length of the lap on the map is 25 cm
So (25 × 1000) = 25000 cm
Since
1 meter = 100 centimeter
So the actual length of the lap = 25000 ÷ 100 = 250 meters
I would use subsitution
y=x-7
sub x-7 for every x
5x+2(x-7)=14
5x+2x-14=14
add 14 to both sides
7x=28
divide both sides by 7
x=4
sub
y=x-7
y=4-7
y=-3
x=4
y=-3
(4,-3)
