Answer:
<em>Arielle has 374 grasshoppers and 187 crickets</em>
Step-by-step explanation:
Let's set:
x = number of grasshoppers
y = number of crickets
Arielle has a collection of 561 insects, thus:
x + y = 561 [1]
The number of grasshoppers is twice the number of crickets, thus:
x = 2y [2]
Substituting [2] in [1]:
2y + y = 561
Simplifying:
3y = 561
Dividing by 3:
y = 561/3
y = 187
From [2]:
x = 2*187 = 374
x = 374
Arielle has 374 grasshoppers and 187 crickets
Let the width of the park be; w
width=w
length=3w
and let the distance between opposite corners of the park be; d
then the expression is; (w)squared +(3w)squared = (d) squared
Answer:
yes
Step-by-step explanation:
Uhm I’m not sure, haven’t did fraction math in a long time
50+20+10+5+1 = $86
.25+.10+.05+.01= 41¢
$100 - $86.41
=
$13.59
