90 days.

For this question you just need to find the least common multiple of 18 and 30. That can be found by first finding the prime factorization of each number. 18 = 2 * 3 * 3 and 30 = 2 * 3 * 5. Then you multiply the 2 * 3 * 3 * 5, you ignore the 3 from 30 because 18 has more 3s. The answer is 90.

Solving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

y = x + 1

3x + 3y = -9

Step 2: Solve for x

Substitution

Substitute in y: 3x + 3(x + 1) = -9
Distribute 3: 3x + 3x + 3 = -9
Combine like terms: 6x + 3 = -9
Isolate x term: 6x = -12
Isolate x: x = -2

Step 3: Solve for y

Define original equation: y = x + 1
Substitute in x: y = -2 + 1
Add: y = -1

Step 4: Graph systems

alexgriva [62]

Answer:

$183.63$ square feet area is covered by seeds per pound

Step-by-step explanation:

Given

$41\frac{1}{4}$ pound bag of seed cover an area of $7575$ square feet

$\frac{165}{4}$ pound bag of seed cover an area of $7575$ square feet

$7575$ square feet area is covered by $\frac{165}{4}$ pound bag of seed

Area in square feet covered by one pound bag of seed

$= \frac{7575}{\frac{165}{4} } \\= \frac{7575 * 4}{165} \\= 183.63$ square feet

Dividing complex numbers

Answer:

DIVIDING COMPLEX NUMBERS

Dividing complex numbers is a little more complicated than addition, subtraction, and multiplication of complex numbers because it is difficult to divide a number by an imaginary number. For dividing complex numbers, we need to find a term by which we can multiply the numerator and the denominator that will eliminate the imaginary part of the denominator so that we end up with a real number in the DENOMINATOR
