Arielle has 374 grasshoppers and 187 crickets in all.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let's set
x = number of grasshoppers
y = number of crickets
Arielle has a collection of 561 insects, therefore
x + y = 561 [1]
The number of grasshoppers is twice the number of crickets, so
x = 2y [2]
Substituting [2] in [1]:
2y + y = 561
Simplifying
3y = 561
Dividing by 3
y = 561/3
y = 187
From [2]:
x = 374
x = 374
Hence, the number of each type of insect that she has 374 grasshoppers and 187 crickets

In 2001, 32 out of 80 members of New Jersey's House of Representatives were Democrats and 25 out of 60 members of Oregon's House of Representatives were Democrats. For each state, write a fraction for the number of Democrats in the House to the total number of House members. Which state had a greater fraction of Democrats in its House of Representatives?
Answer: Oregon
Step-by-step explanation:
For New Jersey:
Number of house of Representatives members = 80
Number of Democrats = 32
Fraction = 32/80 = 2/5
For Oregon:
Number of house of Representatives members = 60
Number of Democrats = 25
Fraction = 25/60 = 5/12
The state that has a greater fraction of Democrats in its House of Representatives is Oregon. This is because 5/12 is greater than 2/5.

Write a linear function g with g(0) = 9 and g(8) = 7.
Answer:
4y = 36-x
Step-by-step explanation:
A linear function is in the form
y = mx + b
for g(0) = 7 ;
x = 0 and y = 9
So ;
9= 0(x) + b
b = 9
For g(8) = 7
x = 8 and y = 7
7 = 8m + 9
7-9 = 8m
8m = -2
m = -2/8 = -1/4
So the equation is;
y = -1/4x + 9
Multiply through by 4
4y = -x + 36

I just answered the question
a teacher has created a 100 point test with 22 questions. If each multiple choice question is worth 4 points and each short answer is worth 6 points. How many of each type are on the test?
Answer:
There are 16 multiple choices and 6 short answers.
Step-by-step explanation:
Let the number of multiple choice questions be x and the number of short answer questions be y.
x + y = 22 (total number of questions)
4x + 6y = 100 (total number of points)
x = 22 - y
4(22 - y) + 6y = 100
88 - 4y + 6y = 100
2y = 100 - 88
y = 6
x + 6 = 22
x = 16
Hence, there are 16 multiple choices and 6 short answers.
Hope this helped!

One of the angle of the triangle is 90 degrees which means it is a right angled triangle. Two angles are same i.e 45 degrees which means the angle is an isosceles triangle.
so, x = 17 (isosceles triangle)
then use pythagoreas theorem:
[tex]y = \sqrt{x {}^{2} + 17 {}^{2} } [/tex]
and x = 17, so simplify and
[tex]y = \sqrt{17 {}^{2} + 17 {}^{2} } [/tex]
so
[tex]y = 17 \sqrt{2} [/tex]

Find the rate of discount when M_P=Rs 2500 and S.P =Rs_2350 The price of a T. V set inclusive of sales tax is RS 33660_If the rate of sales tax is 10% find its basic price.
Answer:
Step-by-step explanation:
The question is in two parts
For the first part;
Mark up price = 2500
Selling price = Rs 2350
To get the discount rate we will use the expression
Discount = MP-SP/MP× 100
Discount = 2500-2350/2500 × 100
Discount =150/2500 × 100
Discount percent = 150/25
discount percent = 6%
For the second part;
Cost of TV = Rs 33660 (including tax)
Sales tax = 10%
Increment = 10% of 33660
Increment = 0.1×33660
Increment = Rs 3366
Basic price = sales price (including tax)-increment
Basic price = 33660-3366
Basic price = Rs 30,294

Step-by-step explanation:
his week, Michael collected $468 for delivering newspapers. He had 40 repeat customers and 18 new ones. As an incentive, he charged the new subscribers $3 less than the repeat customers. If x represents the amount Michael collects from each repeat customer, which equation models this problem? What is the fee Michael charges each new subscriber?
Answer:
$6
Step-by-step explanation:
Let x be the amount Michael collects from each repeat customer
Since we are given that he charged the new subscribers $3 less than the repeat customers.
So, amount collects from each new customer = x-3
Since he had 40 repeated customers
So, the amount Michael collects from 40 repeat customer = $40x
Since he has 18 new customers
So, amount Michael collects from 18 new customer =$18(x-3)
We are also given that his week, Michael collected $468 for delivering newspapers.
Answer:
$6
40x+ 18 (x-3) = 468

how to determine proportional relationship?
In your own words PLEASE
Answer:
to examine the ratio y/x (instead of x/y). If the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y. In this example, that number is 3 (y = 3x), and is called the constant of proportionality.

Answer:
In a graph the line must pass through the origin and it has to be a straight line,
