How would you solve it. I know the answer already. my problem working it out. 4b/2 + 3 = 11 + b.

-3 to both sides
4b/2 = 8 +b

multiply both sides by two
(4b/2 = 8 + b) X2 = 4b = 16+2b

subtract 2b from both sides
2b = 16

divide both sides by 2
b=8

How to solve an equation.

1. Simplify any parentheses using the distributive property if needed.
2. Combine like terms if needed.
3. Use the addition principle of equality if needed.
4. Use the multiplication or division principle of equality if needed.

$\frac{4b}{2} + 3 = 11 + b$
2b + 3 = 11 + b
b + 3 = 11 <-- Subtract b from each side
b = 8 <-- Subtract 3 from each side

So, b is equal to 8.

Answer:

5 units

Step-by-step explanation:

You can use the distance formula or pythagorean theorem to solve this.

Original point A: (0,0)

New point B: (3, 4)

Distance formula: $\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }$

Plug the points in:

$\sqrt{(3-0)^{2} +(4-0)^{2} }$ = 5

Amber, Bernie, and Carlos are working on a problem together. Their goal is to correctly apply the difference of cubes formula to

NeX [460]

Answer: Carlos is correct

Step-by-step explanation:

2x^5-250x^2

The first step is to factorize out 2x^2

2x^2(x^3-125)

This can be rewritten as

2x^2(x^3-5^3),

Recall, difference if cube (a^3-b^3)

= (a-b)(a^2 +ab + b^2)

from our equation,

a= x

b = 5.

So the difference of cubes will be

2x^2[(x-5) (x^2 + 5x + 5^2)]

=2x^2[(x-5) (x^2 + 5x + 25)]

Carlos followed these steps. So he is correct. Carlos is correct because he correctly factored the GCF, identified a and b, and applied the difference of cubes method.

Amber is incorrect because 125 is equal to b3, not b.

Bernie is incorrect because x2 is not the GCF of the polynomial. The GCF is 2x^2.

What is x?? I'm so confused!

LiRa [457]

Answer:

x = 468%

Step-by-step explanation:

I see a proportion here.

we want to solve for the variable x in the proportion:

18% / (2 weeks) = ( x %) / (52 weeks)

here we should multiply 52 to boths sides

(52 weeks) * 18% / (2 weeks) = x %

26 * 18% = x %

x = 468 %

Jer saw 91 squirrels and 1⁄3 as many chipmunks. Which of the following is a good estimation of how many more squirrels he saw th

boyakko [2]

60 more squirrels is the answer because sine its an estimate, 91 turns into 90
therefore u have
90 squirrels and 1/3 as many chipmunks
1/3 of 90 is 30
90 - 30 = 60
Your answer is 60 more squirrels
