Answer:
<h2>width = 7 m</h2><h2>length = 5 m</h2>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 24m
The statement
The length is 30 m less than five times the width is written as
l = 5w - 30
Substitute the expression into the above formula and solve for the width
That's
24 = 2( 5w - 30) + 2w
24 = 10w - 60 + 2w
84 = 12w
Divide both sides by 12
w = 7
Substitute this value into l = 5w - 30
That's
l = 5(7) - 30
l = 35 - 30
l = 5
Therefore the dimensions are
width = 7 m
length = 5 m
Hope this helps you
Answer:1
Step-by-step explanation:
8÷5=1.6 but you don’t want the 6 or the decimal (.) so it’s 1!
Answer:
19 nickels and 5 pennies
Step-by-step explanation:
Let x nickels and y pennies
100 = 5x + y
x + y = 24
y = 24 - x
100 = 5x + 24 - x
4x = 76
x = 19
y = 24 - x = 24 - 19 = 5
Answer:
Step-by-step explanation:
1. exponential because as the values increase by 1, the y values are multiplied by a factor of 1/2.
2. exponential growth because as the time increase by 20 minutes, the cell amount multiplies by 2.
