Answer:

y = 5

multiply:

2 (-1) + y = 3 → -2 + y = 3

rearrange:

y - 2 = 3

add to both sides:

y - 2 + 2 = 3 + 2

simplify:

y = 5

I hope this helps! Sorry if it's the wrong answer! (′д｀σ)σ

The rabbit population in a certain area is 500% of last years population. There are 900 rabbits this year. How many were there t

12345 [234]

Answer:

180 rabbits

Step-by-step explanation:

The correct question is

The rabbit population in a certain area is 500% of last years population. There are 900 rabbits this year. How many were there last year?

we know that

900 rabbits represent 500% of last year population

Last year population represent 100%

using proportion

Find out how many rabbits represent a percentage of 100%

$\frac{900}{500\%}=\frac{x}{100\%}\\\\x=900(100)/500\\\\x=180\ rabbits$

BC is 25 units

Step-by-step explanation:

AB = AC

4x + 4 = 6x - 14

4x + 4 - 4x + 14 = 6x - 14 - 4x + 14

18 / 2 = 2x / 2

9 = x

2(9) + 7

18 + 7

△WPJ∼△DNJ What is PWPW ? Enter your answer in the box.

Kruka [31]

Use CPCTC and make ratios and proportionalities to find the value of segment PW:

If △WPJ∼△DNJ, then according to CPCTC, WP must be proportional to DN and PJ must be proportional to JN. Now, we can make a ratio:

$\frac{WP}{DN}= \frac{PJ}{NJ}$

Substitute the values that are given in the diagram.
DN=87.5
NJ=56
PJ=64

$\frac{WP}{87.5}= \frac{64}{56}$

Solve for x. You can do it by cross-multiplication.

$\frac{WP}{87.5}= \frac{64}{56} \\ 56*WP=64*87.5 \\ 56*WP=5600 \\ WP=100$

The measure of segment WP is 100 meters.
