Step-by-step explanation:
Answer:
6r+7=13+7r
6r+7=7r+13
6r+7−7r=7r+13−7r
−r+7=13
−r+7−7=13−7
−r=6
= 
r=−6

Fraction would be 30/100 and decinal would be .30 and ratio would be 30/100
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.
Answer:
A = 80 S =70
Step-by-step explanation:
#Adults tickets = A
#Students tickets = S
A + S = 150
5A (means the price is $5 times the number of Adult tickets) equals the total amount for all of the Adult tickets altogether
3S (means the price is $3 times the number of Student tickets) equals the total amount for all of the students tickets altogether
5A + 3S = 610 (Means adding the total of all the student tickets plus adult tickets will equal $610 for all tickets sold)
Using both equations now, you can use substitution or elimination to solve for one of the variables. Then you can use the variable to substitute to solve the remaining one.
A + S = 150
5A + 3S = 610
Substitution:
A = 150 - S (Rearrange the first equation by moving S to the other side)
Substitute into the other equation
5 (150 - S) + 3S = 610
750 - 5S + 3S = 610 Combine like terms : -2S = -140
Solve for S = 70
Substitute into A + S = 150 A + (70) = 150
A = 80
