Answer:
1 5/9 ich represent 21 miles
Step-by-step explanation:
Proportions:
2/3 inch ⇔ 9 miles
M inch ⇔ 21 miles
M = 21*(2/3) / 9
M = 14/9
14/9 = 9/9 + 5/9 = 1 + 5/9 = 1 5/9 inch
Answer:
14/9 inches, or an inch and 5/9 of an inch.
Step-by-step explanation:
If 2/3 inch is the same as 9 miles, then x inches represents 21 miles. We can then set up a proportion.
9 * x = (2/3) * 21
9x = 2 * 7
9x = 14
x = 14/9 inches.

Answer:
159 miles
Step-by-step explanation:
The formula for calculating distance is:
Distance= Rate×Time
Distance= 53mph×3hours
Answer= 159 miles
Step-by-step explanation:
log <base a> b = x
means
a^x = b
So
3^2 = x^2+7x+21
x^2 + 7x + 21 - 9 = 0
x^2 + 7x + 12 = 0
(x+3)(x+4)
x = -3 or -4
Answer:
Step-by-step explanation:
x = number of rows
780=x(x+4)
there are 26 rows and 30 students in each row 26*30=780
