of eets in a lase.
She sacenes and
was Soals
She returns the 50 eels to the lake.
The next day Hannah catches 400 ells.
of these 400 eels, 10 are ringed
Work out an estimate for the total number
of eels in the lake.

Answers

Answer 1

Answer:

2000 eels

Step-by-step explanation:

Let us represent the total estimate of the eels = x

She returns the 50 eels to the lake.

The next day Hannah catches 400 eels, of these 400 eels, 10 are ringed.

To solve the above question, we have the following:

50/x = 10/400

Cross Multiply

10x = 50 × 400

x = 50 × 400/10

x = 2000 eels

Therefore, the total estimate of the eels in the lake = 2000 eels

Answer:

x=7

Step-by-step explanation:

You know that the 17x+11 and 19x-3 are equal because they are corresponding angles. Then, you would solve it like an algebraic equation:

17x+11 = 19x-3

Move all the like terms onto one side.

14=2x

It would be easier to look at if moved the x onto the left so it would look like this:

2x = 14.

Then divide by 2 and your answer should be 7.

x=8

Step-by-step explanation:

Angle S and R are remote interior angles which means that they would add up to equal angle RQK.

78+5x-1=15x-3

Combine like terms

77+5x=15x-3

Add 3 on both sides

80+5x=15x

Subtract 5x on both sides

80=10x

Divide 10 on both sides

x=8

How to solve 2(x+13)=9

Answers

Answer:

x = -17/2

Step-by-step explanation:

2(x+13)=9

2x+26=9 (multiplying 2 with both the numbers)

2x=9-26 (shifting 26 on the other side of the equation changes its sign)

2x=-17

x=-17/2 (2 is in multiplication form, so shifting on the other size changes it into division)

Answer:

2 x x + 2x13=8

or,2x+26=9

or,2x=9-26

or,2x= -17

or,x= -17/2

so, x= -8.5

Answer:  B) -4

=========================================================

Explanation:

Point Q is located at (0,w). We see that x = 0 and y = w.

So we'll replace x with 0 and y with w. Then we solve for w.

2x+3y = -12

2(0)+3(w) = -12

0+3w = -12

3w = -12

3w/3 = -12/3

w = -4

In the second to last step, I divided both sides by 3 to undo the multiplication of 3. Saying 3w means "3 times w".

Side note: The point Q is the y intercept as this is the location where the diagonal line 2x+3y=-12 crosses the vertical y axis.

Solve for x.
x2 – 13x + 12 = 0
A. x = -12 and x = -1
