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
Answer: 1 year
Step-by-step explanation:
In 1 year, Kevin will be 40 and Daniel will be 4. 40 is 10 times of 4.
713m/13hrs equals your rate then time = 605m/rate. use the units to help you
13/15 because you’re just adding the ones that aren’t blue. Trust me
Answer:
3a-10=4+a first subtract a from 3a, this equals 2a-10=4 then add 10 to 4, this equals 2a=14, then divide 14 by 2, the answer is a=7
