Answer 1

Answer:

1) 6a - 2b

2) 2a + b

3) 2b + a

4) 4b - a

5) 3(a + b)

Step-by-step explanation:

2a + b ==> 2(3) + 5 = 6 + 5 = 11

2b + a ==> 2(5) + 3 = 10 + 3 = 13

3(a + b) ==> 3(3 + 5) = 3(8) = 24

4b - a ==> 4(5) - 3 = 20 - 3 = 17

6a - 2b ==> 6(3) - 2(5) = 18 - 10 = 8

Now order them from least to greatest

6a - 2b ==> 6(3) - 2(5) = 18 - 10 = 8

2a + b ==> 2(3) + 5 = 6 + 5 = 11

2b + a ==> 2(5) + 3 = 10 + 3 = 13

4b - a ==> 4(5) - 3 = 20 - 3 = 17

3(a + b) ==> 3(3 + 5) = 3(8) = 24

Answer:

x = 14

Step-by-step explanation:

Figure A to Figure B = 1:3.5 = 1/3.5

Therefore:

Side length of figure A to side length of figure B = 1/3.5

Thus:

4/x = 1/3.5

Cross multiply

x*1 = 3.5*4

x = 14

Bryan and Serena had the same amount of money initially. After Bryan donated $258 and Serena donated $234 to charity, Serena had 4 times as much as Bryan. How much had Serena in the end?

Answers

258-234 = 24

24 divided by 4 is 6

Answer:

Serena had $32 at the end.

Step-by-step explanation:

They both had x in the beginning.

Bryan donated $258, so now he has

x - 258

Serena donated $234, so now she has

x - 234

Serena now has 4 times as much money as Bryan.

x - 234 = 4(x - 258)

x - 234 = 4x - 1032

-3x = -798

x = 266

They both had $266.

$266 - $234 = $32

Answer: Serena had $32 at the end.

Answers

When the list of all possible samples of size 3 sessions from this population of 5 sessions are given. The sample minimum session cost should be considered as the $200.

Calculation of the sample minimum session cost:

Since

Session A: $50

Session B: $50

Session C: $100

Session D: $150

Session E: $200

So here the minimum cost be

= $50 + $50 + $100

This ultimately implies that, it is the straight line from the center of a circle to any point on the edge of the circle. Also, radius is half of a diameter i.e diameter divided by the 2.

Generally, the radius is used for calculating the area and circumference of a circle.

Area of a circle = πr²

Circumference of a circle = 2πr

What is the value of x in the equation 2x - 3/5 = -1/10

Answers

Answer:

1/4

Step-by-step explanation:

you add 3/5 to the other side and find the lcm making it 6/10--1/10=5/10. Then 5/10 divided by 2 = 2.5/10 which you can simplify to 1/4.

Answer: x=1/4

Step-by-step explanation:

1. Isolate x: if you move -3/5 to the other side, your equation would become

=> 2x=-1/10+3/5

2. Find the common denominator: since you can't add -1/10 with 3/5 without simplifying, you're equation would change to this:

=> 2x=-1/10+6/10

3. Simplify:

=> 2x=5/10  =>  2x=1/2

4. Divide:

=> 2x=1/2  =>  x=1/2*1/2  =>  x=1/4

Which statement about the properties of Function A and Function B are true?
Select each correct statement.
A The Y-intercept of Function A is equal to the Y-intercept of Function B.
B The Y-intercept of Function A is less than the Y-intercept of Function B.
The Y-intercept of Function A is greater than the Y-intercept of Function B.
D The rate of change of Function A is equal to the rate of change of Function B.
E The rate of change of Function A is less than the rate of change of Function B.

Answers

Answer:

B. The Y-intercept of Function A is less than the Y-intercept of Function B

F. The rate of change of Function A is greater than the rate of change of Function B

Step-by-step explanation:

Function A rate of change and y-intercept:

✔️Rate of change using two pairs of values from the given table, (1, 2) and (3, 10):

Rate of change = ∆y/∆x = (10 - 2) / (3 - 1) = 8/2 = 4

Rate of change (m) of Function A = 4

✔️ To find the y-intercept (b) of function A, substitute (x, y) = (1, 2) and m = 4 into y = mx + b (slope-intercept form):

2 = 4(1) + b

2 = 4 + b

2 - 4 = b

-2 = b

b = -2

Y-intercept (b) of function A = -2

Function B rate of change (m) and y-intercept (b):

The function, y = 3x + 4 is given in the slope-intercept form, y = mx + b.

Therefore,

Rate of change/slope (m) = 3

Y-intercept (b) = 4

The following staments about the properties of both functions are therefore true:

B. The Y-intercept of Function A is less than the Y-intercept of Function B

F. The rate of change of Function A is greater than the rate of change of Function B

The atomic mass of a chemical element is the number of protons + number of neutrons in each atom of that element—electrons are ignored. Examples The atomic mass of hydrogen (H) is 1 (1 proton) and that of helium (He) is 4 (2 protons + 2 neutrons).

The gram atomic mass of a chemical element is the atomic mass of that element in grams. Example The gram atomic mass of H is 1 gram and that for He is 4 grams.

Astounding Fact There are approximately 6 x 1023 atoms in the gram atomic mass of every known chemical element. Examples There are 6 x 1023 atoms in 1 gram of H and in 4 grams of He. Hence, there are 12 x 1023 atoms, or 1.2 x 1024 atoms, in 2 grams of H and in 8 grams of He.

Standard carbon is Carbon 12, abbreviated C-12. Its atomic number is 12 (6 protons and 6 neutrons) and its gram atomic mass is therefore 12 grams.

(a) 1.2 x 1024 atoms (b) 12 x 1023 atoms (c) 4.8 x 1023 atoms

discount = discount percent × original price ÷ 100

$1.50 = discount percent × $4.50 ÷ 100

Jack and Jill are 432 meters apart, but are walking towards each other. Joe walks at a pace of 2 meters per second, while Jill walks at a pace of 3 meters per second. After how many seconds will they meet up?

Answers

Answer:

86.4 seconds.

Step-by-step explanation:

Given that Jack and Jill are 432 meters apart, but are walking towards each other, and Joe walks at a pace of 2 meters per second, while Jill walks at a pace of 3 meters per second, to determine after how many seconds will they meet up, the following calculation must be performed:

432 / (3 + 2) = X

432/5 = X

86.4 = X

So, Jack and Jill will meet after 86.4 seconds.

1. Elena donates some money to charity whenever she earns money as a babysitter. The table shows how much money, d, she donates for different amounts of money, m, that she earns.

a. What percent of her income does Elena donate to charity?

b.Which quantity, m or d, would be the better choice for the dependent variable in an equation describing the relationship between m and d.

PLEASE HELP!!! THANK YOU!!❤️

Answers

(a). Elena donates 12% of her income.

(b). d (amount donated) will be a better choice for the dependent variable, as it is always dependent on the income of Elena.

What is a dependent variable?

You can control or set the independent variable. It affects the dependent variable, which changes as a result. The input is unrelated to the result, which is the dependent variable.

As per the given data:

money donated from money earned is given in the table.

For percent of her income donated to charity:

Total money donated / Total money earned

= (4.44 + 1.80 + 3.12 + 3.60 + 2.16) / (37 + 15 + 26 + 30 + 18)

= (15.12)/(126)

= 0.12

∴ Elena donates 12% of her income.

Hence, Elena donates 12% of her income and d (amount donated) will be a better choice for the dependent variable as it is always dependent on the income of Elena.

If we reverse it we can break it down easier: We start at $935

15 dollars on every purchase, he sold 11 TVs. So we find the total amount of money, 15*11=165

935-165=770

770 is the amount left without the money he has earned so the total base.

770/11=70

Checking answer

Let's rebuild it to test if it is correct...

$70 for each tv * 11 tv's = $770 or the base price of the tv's

$15 for all the warranties

$15*11=165

165+770=935

So the answer is 70$
