Question

There are twice as many ants as roaches.

This seemed like an easy question, but it's something that a lot of people mess up. Thanks for all the input!

Answer 1

Let r = number of roaches
Let x= number of ants

x=2r

Example: If there are 50 roaches and twice as many ants, then 50*2=100 ants...which is twice the number of roaches.

Answer 2

There are twice as many ants as roaches

If A = ants
and R=Roaches

then r=(1/2)A or A=2R

For example, if there are 50 roaches, then there would have to be 100 ants

Using the formula

50=(1/2)A A=100

or

A=(2)(50) A=100

Answer 3

let A stand for ants and R for roaches, then your statement becomes:

A=2R

Answer 4

The minimum value or optimal value of a quadratic function refers back to the vertex of the function and wherein direction the parabola of that function opens up while graphed. If the parabola opens down (curves upward), then the vertex is the utmost area of the function and its the parabola's optimal value. If the parabola opens up (shaped like a bowl), then the vertex is the backside area of the function and is the parabola's minimum value. as a fashion to make certain whether a quadratic function has a minimum or optimal value, you in simple terms look on the x^2 term of the function. If its coefficient is valuable, the parabola opens up and has a minimum value. If its coefficient is detrimental, the parabola opens down and has a optimal value. So in y = -6x^2 + 4x + 3, you are able to make certain that the parabola has a optimal value, and in y = x^2 + 2x + 7, you are able to make certain that the parabola has a minimum value.

Answer 5

Let's use A for ants and R for roaches.

Your equation would read:

2A=R

Or two times "ants" equals "roaches."

Good enough?

Answer 6

let number of ants be x
let number of roaches be y

y = 2*x

Answer 7

R= roaches
A= ants

2A=R

Answer 8

2a=r
r=roaches
a=ants

Answer 9

Let a = number of ants
Let r = number of roaches

a = 2r

Answer 10

2a=r
or
a=r/2
