Answer:
the original population was 425
Step-by-step explanation:
425
Let the original population of blackbirds be x.
<u>Original population</u> <u>decreases by</u> <u>New population</u>
100 24 76
x 24 323
<u>Now we can make an expression like this.</u>
100 ⇒ 76
x ⇒ 323
And now let us use cross multiplication and solve for x.
<u>Let us solve it now.</u>
323 × 100 = 76x
32300 = 76x
<u>425</u>= x
poor you
29/40
29 ÷ 40
the answer is 0.725 all you have to do is divide the numerator by the denominator
(x+9)(x+5)
find 2 numbers that add to 14 and multiply to 45
