Factor -1/3 out of 1/3y - 3/2?

1 answer:

6 0

In order to factor a value out of an expression we must divide each term by this value, so ((1/3)*y - 3/2)/-(1/3) = (-1/3)*(-y + 9/2)

7v=2v-20 what is the answer

Ierofanga [76]

7v = 2v - 20

First, subtract 2v from both sides. / Your problem should look like: 7v - 2v = -20
Second, simplify 7v - 2v to 5v. / Your problem should look like: 5v = -20
Third, divide both sides by 5. / Your problem should look like: v = $- \frac{20}{5}$
Fourth, simplify $\frac{20}{5}$ to 4. / Your problem should look like: v = -4

Answer: v = -4

Answer:

$P_{native}\:=\:3.186\times10^8$

Step-by-step explanation:

Population that didn't immigrated = Total Population - Population that immigrated

$P_{native}\:=\:P_{total}\:-\:P_{immigrants}$

$P_{native}\:=\:3.2\times 10^8-1.4\times 10^6$

$=3.2\times 10^8-1.4\times 10^6\times \frac{100}{100}\\\\=3.2\times 10^8-\frac{1.4}{100}\times 10^6\times 10^2\\\\=3.2\times 10^8-0.014\times 10^{6+2}\\\\=3.2\times 10^8-0.014\times 10^8\\\\=10^8\left(3.2-0.014\right)\\\\=3.186\times10^8$

What is the value of x

Crank

Answer:

Step-by-step explanation:

Looking at the diagram,

Line DT is parallel to line line BM, therefore, triangle DHT is similar to triangle BHM. This means that

DH/DB = TH/MH

DH = 15 + 6 = 21

TH = 9 + x

Therefore

(9 + x)/21 = 9/6

Cross multiplying, it becomes

6(9 + x) = 21 × 9 = 189

54 + 6x = 189

Subtracting 54 from the left hand side and the right hand side of the equation, it becomes

6x + 54 - 54 = 189 - 54

6x = 135

Dividing the left hand side and the right hand side of the equation by 6, it becomes

6x/6 = 135/6

x = 22.5

lesya [120]

Answer:

3 ≤ x ≤ 7 or x is between 3 and 7, inclusive

Step-by-step explanation:

Eira's graph probably resembled the diagram below.

The domain is the set of all possible x-values that will make a function work.

x can take any value from 3 to 7.

The domain is [3, 7] or 3 ≤ x ≤ 7.
