Como resolver 2a(ab+b)-b (3x+a2) eliminando os parenteses

To order 0.14, 1/8, and 1.9% from least to greatest, we first convert them all to decimal form, which gives us 0.14, 0.125, and 0.019 respectively. The ordered list from least to greatest is 1.9%, 1/8, 0.14.

The question requires ordering the numbers 0.14, 1/8, and 1.9% from least to greatest. First, we convert all numbers to decimal form: 0.14 remains the same, 1/8 is equivalent to 0.125, and 1.9% is the same as 0.019 when converted to decimal form. Now, we have 0.14, 0.125, and 0.019. Ordering these decimals from least to greatest, we get 0.019, 0.125, and 0.14.

Therefore, when ordered from least to greatest, 1.9%, 1/8, and 0.14 become 1.9%, 1/8, and 0.14 respectively.

Final answer:

To solve the inequality 10 ≥ - 2/3 (9+12B) for b, first eliminate the fraction by multiplying both sides by -3/2, then isolate b, resulting in b ≥ -2.

Explanation:

The student has asked to solve the inequality for b: 10 ≥ - 2/3 (9+12B). To do this, follow these steps:

Multiply both sides of the inequality by the reciprocal of -2/3, which is -3/2, to get rid of the fraction. This step is crucial for simplifying the inequality.

The inequality becomes: -15 ≤ 9 + 12B.

Subtract 9 from both sides to isolate the term with b on one side: -24 ≤ 12B.

Divide both sides by 12 to solve for b: b ≥ -2.

Therefore, the solution to the inequality 10 ≥ - 2/3 (9+12B) is b ≥ -2.

Domain and Range of the function are  [tex][0, 10] \; \&\; [0,30][/tex] and it is a discrete function.  

Explanation:

Given: The function [tex]m=30-3r[/tex] represents the amount [tex]m[/tex] (in dollars) of money you have after renting [tex]r[/tex] video games.

According to question,

Function is  [tex]m=30-3r[/tex].

Domain of function is calculated as [tex]30-3r=0[/tex]

                                                                 [tex]-3r=-30\\[/tex]

                                                                     [tex]r=\frac{-30}{-3} \\r=10[/tex]

Domain of function is [tex][0, 10][/tex].

Now, range of the function is the value which is dependent variable on domain of the function.

Range of the function is [tex][0,30][/tex].

Here, The given function  [tex]m=30-3r[/tex] is discrete because the values of  [tex]r[/tex] and [tex]m[/tex] cannot take every value in the number line.

Therefore, Domain and Range of the function are  [tex][0, 10] \; \&\; [0,30][/tex] and it is a discrete function.

Answer:

The fraction taken away from 17 is [tex]\frac{16}{3}[/tex]

Step-by-step explanation:

The simplest way to solve this word problem is to set to equations equal to one another and solve the missing fraction.

The one side of the equation is 17 subtracted by an unknown fraction.

The other side is one third of seventeen added to 6.

[tex]17-x=\frac{1}{3}(17)+6\\x=17-6-\frac{1}{3}(17)\\x=11-\frac{17}{3} \\x=\frac{33}{3} -\frac{17}{3}\\x=\frac{16}{3}[/tex]

the answer gotta be b or d

You have the first part correct. The area 36pi comes from squaring 6 to get 36.

The diameter 12 is cut in half to get the radius 6.

Add on 3 to the radius to get 3+6 = 9. The new radius is 9 which squares to 81. That's why the answer is choice D for the problem on the right.

Answer:

MNO

Step by step:

A translation is the shifting of a figure from one place to another without rotating, reflecting or changing its size. So when you look at all of the answer choices then look at the definition of translation you see that MNO fits all the criterias.

(I am going with the assumption that this is the question since you gave no picture.)

If Huda made 8 matching bracelets. She used 128 beads in all. Then 16 beads she used per bracelet.

A division is a process of splitting a specific amount into equal parts.

Given,

The number of beads Huda used are one hundred twenty eight

Number of beads=128

The number of bracelets huda made by using 128 beads is 8 bracelets.

We have to find in each bracelet how many beads Huda used.

This can be achieved by division.

We have to split 128 beads into eight groups.

128/8=16

In each group has 16 beads. Which means each bracelet has 16 beads.

Hence 16  beads she used per bracelet.

Let us say that:

x = number of students who are members.

Since both groups went together to the planetarium, therefore this means that 19-x is the number of students who are not member

Since x paid $11 for tickets and (19-x) paid $13 so the total cost of the tickets is:

$11x + $13(19-x) = $209

Solving for x would get us the number of members:

11x + 247 – 13x = 209

-2x = -38

x = 19

Therefore this means that all students are members.

If each building in the apartment complex has 4 three-bedroom units and they build 50 buildings, there would be 200 three-bedroom apartments total.

To answer how many 3-bedroom apartments would be in the complex if they built 50 buildings, start by considering the number of 3-bedroom apartments in one building. You've advised that this number is 4. Thus, to find the total number of 3-bedroom apartments in 50 buildings, you would multiply 4 (the number of 3-bedroom apartments per building) by 50 (the number of buildings). This calculation yields: 4 * 50 = 200. So, there would be 200 three-bedroom apartments in the complex if 50 buildings were constructed.
