STOP !! I NEED HELP ON MY HOMEWORK AND ITS DUE TOMORROW. PLEASE HELP ME. THANK YOU

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:

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:

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

Step-by-step explanation:

As we said, points on the coordinate plane are represented as (a, b), where a and b are rational numbers. Rational numbers are numbers that can be written as a fraction, p/q, where p and q are integers. We call a the x-coordinate of the point and we call b the y-coordinate of the point.

Answer:

interest: 8 interest rate: 16

Step-by-step explanation:

the interest is 8$ since you payed 8$ extra, the interest rate can be counted in another way but I forgot it. So 50 is 100%, you divide it by 100 and get 0.5. then you take 8/0.5 which means how many percent there is in 8 which is 16.

This can be solved much easier if you multiply by 2. you borrow 100 and get 116 in return. both interest and interest rate is 16

The interest is $8 and rate of interest is 16%.

Using the interest rate formula, we get the interest rate, which is the percentage of the principal amount, charged by the lender or bank to the borrower for the use of its assets or money for a specific time period. The interest rate formula is

Interest Rate = (Simple Interest × 100)/(Principal × Time).

Given:

Interest = $58 - $50 = $8

Time = 6 months = 1/2 hours

Principal = $50

rate = ?

Thus, the rate of interest

= 8 x 100 /  50

=800 /50

= 16%

Hence, the interest is $8 and rate of interest is 16%.

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

Answer:

(6y+10)^2

Step-by-step explanation:

right answer

Step-by-step explanation:

3x - 4y = 16

-4y = 16 - 3x

y = -(16 - 3x)/4

2x + 3y = 5

2x + -3(16 - 3x)/4 = 5

(8x - 48 + 9x)/4 = 5

17x - 48 = 20

17x = 68

x = 68/17

x = 4

3x - 4y = 16

3(4) - 4y = 16

12 - 4y = 16

-4y = 4

y = 4/-4

y = -1

Solution = (4,-1)

[tex]8x(-8)+2[/tex]

there you go

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

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.

Step-by-step explanation: divide 8658 by 9

Using the percentage concept, the amount of fat, protein and Carbonhydrate to be consumed per day are 360, 540 and 900 calories respectively.

We can calculate the amount of calories for each nutrient class per day thus :

Carbonhydrates :

0.5 × 1800 = 900

Protein :

0.3 × 1800 = 540

Fat :

0.2 × 1800 = 360

Hence, the amount of fat, protein and Carbonhydrate to be consumed per day are 360, 540 and 900 calories respectively.

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)
