The first one

7a - 10c - 2a - 1/2c + 5
7a -2a - 10c - 1/2c + 5
5a -10.5c + 5

X+5-8x=26<br> Solve for x

salantis [7]

X = -3

Pull out the like terms: -7x - 21 = -7 × ( x + 3)

Solve: -7 = 0

Solve: x + 3 = 0

Subtract 3 from both sides of the equation

So, x = -3

Consider the two expressions 4b(b+1) and (2b+7)(2b-8). Compare their values if b=-3, b=-2, and if b=10. Is it true that for an v

frutty [35]

Answer:

FIRST EXPRESSION:

- If $b=-3$ , the value of $4b(b+1)$ is $24$

- If $b=-2$ , the value of $4b(b+1)$ is $8$

- If $b=10$ , the value of $4b(b+1)$ is $440$

SECOND EXPRESSION:

- If $b=-3$ , the value of $(2b+7)(2b-8))$ is $-14$

- If $b=-2$ , the value of $(2b+7)(2b-8))$ is $-36$

- If $b=10$ , the value of $(2b+7)(2b-8))$ is $324$

Yes, for any value of "b" the value of the first expression is greater than the value of the second expression.

Step-by-step explanation:

Substitute the given values of "b" into each expression and evaluate.

- For the first expression $4b(b+1)$ , you get:

If $b=-3$ → $4(-3)(-3+1)=24$

If $b=-2$ → $4(-2)(-2+1)=8$

If $b=10$ → $4(10)(10+1)=440$

- For the second expression $(2b+7)(2b-8))$ , you get:

If $b=-3$ → $(2(-3)+7)(2(-3)-8)=-14$

If $b=-2$ → $(2(-2)+7)(2(-2)-8)=-36$

If $b=10$ → $(2(10)+7)(2(10)-8)=324$

You can observe that for any value of "b" the value of the first expression is greater than the value of the second expression.

What is the perimeter of rhombus LMNO?

kicyunya [14]

If you see that 3x-3 and set it equal to x+7 then you will get this,

3x-3=x+7

Now solve for X. You will get 5.

Then you plug five in and get 12 For both sides and then multiply 12 by 4 and get 48.

You answer is 48.

Hope this helps you.

Answer

$P(t) = 19100. e^{0.06t}$

b) P(8) =30866

Step-by-step explanation

Use formula:

$P(t) = P. e^{rt}$

Here, P = 19100

r = 6% = 0.06

$P(t) = 19100. e^{0.06t}$

b) t = 2008 - 2000 = 8

$P(8) = 19100. e^{0.06\times 8}$

$P(8) = 19100. e^{0.48}$

$P(8) = 19100\times 1.616\\\\P(8) = 30,865.6\\\\P(8) \approx 30,866$

Emily is picking strawberries at a speed of 3 strawberries per second. Her little sister Sophia joins Emily when there are 20 st

Zina [86]

Answer:

6 seconds

Step-by-step explanation:

Using the information from the problem, if Emily continues to pick 3 strawberries per second while Sophia eats 5 strawberries per second, then the amount of strawberries will decrease at a rate of 2 strawberries per second. Therefore, we can find the answer by subtracting 2 from 20 until we get to 8. Since we subtract 2 six times, the answer is 6. Hope this makes sense!
