Answer:
a. 12 minutes
b. 34 minutes
Step-by-step explanation:
Here, we are told that Ima has driven 5 minutes before Polly started driving
So if Ima has driven for x minutes , polly would have driven for y minutes but the difference between x and y is 5
So mathematically;
x = y + 5
a. 17 = y + 5
y = 17-5 = 12 minutes
b. x = 29 + 5
x = 34 minutes

Answer:
1.1, -5
Step-by-step explanation:
53 - 9y = 1
from equation i
53-9y = 1
-9y= 1-53 = -52
y = -52/-9= 52/9 = 5⁷/₉
-7.2 + 2y = -5
add 7.2 to both sides
2y= -5+7.2 = 2.2
y= 2.2/2 = 1.1
The area of a square is expressed as:
Area = s^2
We are given the area of both windows. We will use this value for the calculations. We set s as the side of the larger window and a for the smaller window.
Total area = Area larger + area smaller
1025 = s^2 + a^2
Since it was said that the side of the larger window, s is 5 in longer than the side of the smaller window, a (s = 5+a) then:
<span>1025 = s^2 + a^2
</span>1025 = (5+a)^2 + a^2
simplifying we obtain,
a = 20 inches
