Things we know: every pound of cherries cost four dollars.

We don't know how much the mother got and it is represented by the variable 'r'. But we do know how many pounds the dad got. He got two pounds.

We know the total cost the mom had to pay which is 4 * r and the amount the dad paid is 4 * 2 or 8.

Now we want to make an algebraic expression that represents how much more the mother paid than the father.

Final answer:

8 - (4 * r)

Hope this helps!

-2|3-2r|<-34 how do you solve this?

Alexxandr [17]

$|a| -b\\\\|a|>b\iff a>b\ or\ a$

$-2|3-2r|34\qquad\text{divide both sides by 2}\\\\|3-2r|>17\iff3-2r>17\ or\ 3-2r14\ or\ -2r$

Assume all variables represent non negative numbers . Help please!!

Dafna1 [17]

Answer:

A). $2p^{8}$

B). $3m^{7}$

Step-by-step explanation:

A). $\sqrt{4p^{16}}$

To get the square root of the given expression we will convert it into the square form.

$4p^{16}=(2)^2(p^{8})^2$ [Since 2×2 = 4 and $p^{8}\times p^{8}=p^{16}$ ]

Therefore, $\sqrt{4p^{16}}=\sqrt{2^{2}\times (p^{8})^2 }$

$=2p^{8}$

B). $\sqrt{9m^{44}}$

Since, $9m^{14}=(3)^2\times (m^7)^2$

Therefore, $\sqrt{9m^{44}}=\sqrt{(3)^2\times (m^7)^2}$ [Since 3² = 9 and (m⁷)² = m¹⁴]

$=3m^{7}$

Solve the equation 4x²+4x+1=0

Natasha2012 [34]

Answer: x = -1/2

4x² + 4x + 1 = 0

⇔ (2x + 1)² = 0

⇒ 2x + 1 = 0

⇔ x = -1/2

An electrician has 4.1 meters of wire how many strips 7/10 meter can he cut

spin [16.1K]

Turn 7/10 into decimal. (0.7)

Keep adding by 0.7 until you get the number closest to 4.1

3.5 is the closest, if we add another 0.7, we get 4.2.

So, he can get 5 sections of 0.7m
