First you divide 1200 by 25 (1200/25) it comes out to 48.
That means the he types at a rate of 48wpm. So then all you have to do is multiply 48 and 45 and you get 2160 words.
Answer:
X=-5y/13+90/13, Y=-13x/5+18
Step-by-step explanation:
You need to solve the equation for X and Y.
Solving for X:
13x+5y=90
Subtract 5y: 13x=-5y+90
Divide by 13: x=-5y/13+90/13
--
For Y:
13x+5y=90
Subtract 13x: 5y=-13x+90
Divide by 5: y=-13x/5+90/5
(Simplifies to -13x/5+18)

Answer:
Step-by-step explanation:
Area of one road = 700 x 10
7000 sq m
area of another road
= 300 x 10 = 3000sq m
Total area of road
= 7000 + 3000 - 10 x 10
= 9900 sq m
Area of park
= 700 x 300
= 210000 sq m
less area of road
= 210000 - 9900
= 200100 sq m
= 200100 / 10000 hectare
= 20.01 hectare.
