Solve for a
7a - 2b = 5a + b
A. a = 2b
B. a = 3b
C. a = 3/2b
D. a = 2/3b​

Step-by-step explanation:

sum of numbers divided by how many numbers there are.

(2/4 + 18/5 + 28/10 + 5/20)/4

we bring all fractions to .../20, as 20 is the smallest common multiple of all denominators. and then we can easily sum them all up.

so,

(10/20 + 72/20 + 56/20 + 5/20)/4 =

143/20 / 4 = 143/20 × 1/4 =

= 143/80 is the mean or average

Answer:

b. 4x-5

Step-by-step explanation:

Richard had 5 less than Max. Ben has 4 times more than Richard. Max has x

4x-5

4x is 4 times more than richard, but has 5 less than max. So, 4x is Ben, but its 5 less than Max, so -5

Explanation:

Given a triangle with sides a and b, the third side c is bounded by this compound inequality

b-a < c < b+a

where a < b

--------

In this case, a = 16 and b = 26, so

b-a < c < b+a

26-16 < x < 26+16

10 < x < 42

I'm using a version of the triangle inequality theorem.

This unknown third side is between 10 cm and 42 cm. The third side cannot equal 10 nor can it equal 42.

Answer:

For this case we have the following expression:

(3/8)d + 3/4(3/8)d+3/4

We must factor the term that accompanies the variable.

We have then:

(3/8) (d + (3/4) * (8/3))(3/8)(d+(3/4)∗(8/3))

Rewriting the expression we have:

(3/8) (d + 8/4) (3/8) (d + 2)(3/8)(d+8/4)(3/8)(d+2)

We're going to check the result. To do this, we multiply the term 3/8 for each term within the parenthesis:

(3/8) d + 2 (3/8)(3/8)d+2(3/8)

Rewriting:

(3/8) d + 3/4(3/8)d+3/4

The factorization is correct.

(3/8) (d + 2)

[tex]\frac{-1}{a+b}[/tex]

Step-by-step explanation:

Let's solve for x.

Ax+bx−3=−4

Step 1: Add 3 to both sides.

Ax+bx−3+3=−4+3

ax+bx=−1

Step 2: Factor out variable x.

X(a+b)=−1

Step 3: Divide both sides by a+b.

[tex]\frac{x(a+b)}{a+b} =\frac{-1}{a+b}[/tex]

The answer is x  =  124 ,  − 119

Using the slope - intercept relation, the equation of the line is y = 1.25x - 2508

The slope - intercept form of the equation can be obtained thus :

Slope, b = (y2 - y1) ÷ (x2 - x1)

Slope, b = (4.5 - 2.0) ÷ (2010 - 2008)

Slope = 2.5 / 2 = 1.25

Using any of the pair of points we can obtain the intercept thus :

2 = 1.25(2008) + c

2 = 2510 + c

2 - 2510 + c

c = - 2508.

Hence, the equation is y = 1.25x - 2508

Answer:

Using the slope - intercept relation, the equation of the line is y = 1.25x - 2508

The slope - intercept form of the equation can be obtained thus :

General form ; y = bx + c

Slope, b = (y2 - y1) ÷ (x2 - x1)

Slope, b = (4.5 - 2.0) ÷ (2010 - 2008)

Slope = 2.5 / 2 = 1.25

Using any of the pair of points we can obtain the intercept thus :

2 = 1.25(2008) + c

2 = 2510 + c

2 - 2510 + c

c = - 2508.

Hence, the equation is y = 1.25x - 2508

Answer:

37.5%

Step-by-step explanation:

Okay, so he gets up at 7:00. He goes to bed at 10:00. So, 10, into 12 thats two hours and then 7 thats another seven hours, so 9 hours he is in bed. Theres 24 hours in a day so thats 9 hours out of the day. If we turned that into a percentage that would be %62.5 hours in a day he is not sleeping, and 100 - 62.5 would be 37.5.

The answer is 37.5

Answer:

j = 2d - 3

d = 11

Step-by-step explanation:

a. If Dante has d candies, write an expression to represent how many candies Jessica has.

j = 2d - 3

b. If Jessica has 19 candies, write and solve an equation to find out how many candies Dante has.

19 = 2d - 3

add 3 to both sides

22 = 2d

Divide both sides by 2

11 = d

d = 11

a) There are (2d - 3) candies Jessica has.

b) There are 35 candies Dante has.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Jessica has three fewer candies than twice the number Dante has.

a) Let number of candles Dante has = d

So, Number of candles Jessica has = 2d - 3

b) Here, number of candles Dante has = 19

So, Number of candles Jessica has = 2×19 - 3

                                                       = 35

Step-by-step explanation:

very simple : the terms with the same base (either a specific number or a variable with the same exponent, or a function ...) can be combined.

4a - 3b + 6a

which terms here have the same base ?

ah, 4a and 6a refer to the same variable (and with the same exponent : 1, as a = a¹).

therefore, I can combine them :

4a + 6a = a×(4+6) = a×10 or simply 10a

so the result is

10a - 3b

Answer:

20000

Step-by-step explanation: If it doubles every 27 years and its asking if 54 years had passed then it would be 5000*4 which is 20,000

Brainliest is appreciated

Answer: 20,000

Step-by-step explanation:

Because the population doubles every 27 years, the population will double twice since 54/27 = 2

5,000 * 2 = 10,000

10,000 * 2 = 20,000

Alternatively you can add instead of multiplying

5,000 + 5,000 = 10,000

10,000 + 10,000 = 20,000
