72 + 78 + 70 + x > = 289 (thats greater then or equal)

or
220 + x > = 289

Answer:

The number of mosquitoes that will inhabit the city on May 25 is 4,471,200.

Step-by-step explanation:

Note: This question is not complete as some important figures and points are omitted. The complete question is therefore provided before answering the question as follows:

An unusually wet spring has caused the size of a mosquito population in some city to increase by 8% each day. If an estimated 180,000 mosquitoes are in the city on May 12, find how many mosquitoes will inhabit the city on May 25. Use y= 180,000(1.08)x where x is number of days since May 2.

The explanation to the answer is now given as follows:

Given;

y = 180,000(1.08)x = 180,000 * 1.08 * x .................... (1)

Where;

y = Number of mosquitoes that will inhabit the city on May 25 = ?

x = Number of days since May 2 = 25 - 2 = 23

Substituting for x = 23 into equation (1), we have:

y = 180,000 * 1.08 * 23

y = 4,471,200

Therefore, the number of mosquitoes that will inhabit the city on May 25 is 4,471,200.

What is<br> -1 5/6 - (-3 1/4) ?

lions [1.4K]

Answer:

$1\frac{5}{12}$

Step-by-step explanation:

Eliminating a negative and changing our operation

$1\frac{5}{6} +3\frac{1}{4}$

Rewriting our equation with parts separated

$-1-\frac{5}{6} +3+\frac{1}{4}$

Solving the whole number parts

$-1+3=2$

Solving the fraction parts

$-\frac{5}{6} +\frac{1}{4} =[?]$

Find the LCD of 5/6 and 1/4 and rewrite to solve with the equivalent fractions.

LCD = 12

$-\frac{10}{12} +\frac{3}{12}=-\frac{7}{12}$

Combining the whole and fraction parts

$2-\frac{7}{12} =1\frac{5}{12}$
