Answer:

product is a ⋅ c = 3 ⋅ − 6 = − 18 and whose sum is b = − 7 .

Step-by-step explanation:

Factor

− 7 out of − 7 x .

3 x 2 − 7 ( x ) − 6

Rewrite

−7 as 2 plus −9

3 x 2 + (2−9) x −6

Apply the distributive property.

3 x 2 + 2 x − 9 x − 6

Answer:

12 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Put 5 in fraction form ( [tex]\frac{5}{1}[/tex] ) and multiply it by [tex]\frac{5}{2}[/tex]

[tex]\frac{5}{1}[/tex]×[tex]\frac{5}{2}[/tex] = [tex]\frac{25}{2}[/tex]   now simplify  to 12 [tex]\frac{1}{2}[/tex]

1) Answer:

[tex]h = \frac{3}{2} [/tex]

2) Answer:

[tex]a = \frac{160}{3} [/tex]

3) if you mean,

[tex] \frac{3}{5} x = 12[/tex]

Then the answer is. x = 20.

but, if you mean

[tex] \frac{3}{5x} = 12[/tex]

then the answer would be, x = 1/20.

4) Answer:

[tex]y = \frac{5}{7} [/tex]

5) If you mean,

[tex] \frac{14}{3} = - \frac{7}{9b} [/tex]

then the answer would be, b = -1/6

but if you mean,

[tex] \frac{14}{3} = - \frac{7}{9} b[/tex]

then the answer would be, b = -6

8*22 = 22*8

Answer: 720

Step-by-step explanation:

From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.

If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:

1/20 × x = 36

x/20 = 36

x = 20 × 36

x = 720

The turtle population is 720

Answer: [tex]15\times\frac{1}{2}[/tex]

Explanation:

Multiplying by 1/2 is the same as dividing by 2.

For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say [tex]10\times \frac{1}{2} = 5[/tex]

The fraction 1/2 converts to the decimal form 0.5, which means [tex]10 \times \frac{1}{2} = 10*0.5[/tex]

Answer:

6 * 10^2

Step-by-step explanation:

Simplify : (4.2×10^7)÷(7×10^4)

(4.2 × 10^7) / (7 × 10^4)

From indices : 10^a ÷ 10^b = 10^(a - b)

(4.2 / 7) * 10^(7-4)

0.6 * 10^3

= 6 * 10^2

Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2

Answer:

It took Riley 9 hours to clean the garage.

Step-by-step explanation:

With the information provided, you can say that the amount Riley earns for cleaning the garage is equal to the price per hour for the number of hours it takes to clean the garage, which can be express as:

x=4.25y, where:

x is the amount Riley earns for cleaning the garage

y is the number of hours it takes to clean the garage

Now, you can replace x with $38.25 that is the amount that Riley earned and you can solve for y to find how long it took her to clean the garage:

38.25=4.25y

y=38.25/4.25

x=9

According to this, the answer is that it took Riley 9 hours to clean the garage.

Answer:

x=9                   x=-1

Step-by-step explanation:

2(x-4)^2=50

Divide each side by 2

2/2(x-4)^2=50/2

(x-4)^2=25

Take the square root of each side

sqrt((x-4)^2)=sqrt(25)

x-4 = ±5

x-4 =5            x-4 = -5

Add 4 to each side

x-4+4=5+4    x-4+4 = -5+4
