What is 8z + x -5 - 9z + 2 written in simplest form

Answer:

22x-12y

❤❤

hope its helpful ❤❤❤❤

THANK YOU.

Answer:

Since they are similar their sides are corresponding,

9x + 1 / x + 5 = 49 / 14

or, 14 ( 9x + 1 ) = 49 ( x + 5 ) { cross multiply}

or, 126x + 14 = 49x + 245

or, 77x = 231

or, x = 231/77

or, x = 3

Answer:

56 = 56

Step-by-step explanation:

Given:

Bus fare = $2.00

coupon book = 28.00

bus fare w/ coupon book = $1.00

let x be the number of bus rides.

2.00x = 1.00x + 28.00

2.00x - 1.00x = 28.00

1x = 28.00

x = 28.00

24 bus rides for both to have the same cost.

2.00x = 1.00x + 28

2.00(28) = 1.00(28) + 28

56 = 28 + 28

56 = 56

Answer:

The answer is ±6.

Step-by-step explanation:

The positive and negative square roots of 36 are 6. and −6. Both 6, and −6 are square roots of 36 since they both give 36 when squared:...

6^2=6×6=36

(−6)2=(−6)×(−6)=36

All positive real numbers have a positive and negative real square root which are additive inverses of one another.

The principal square root is the positive one and is the one meant when we use the √... symbol. So:...

√36=6

If we want to refer to the negative square root, then just put a minus sign in front:...

−√36=−6

The two square roots of -36 are 6i and -6i, where i is the imaginary unit.

A number system is defined as a system of writing to express numbers.

Since the square of any real number is always non-negative, there is no real number whose square is equal to a negative number.

Therefore, the expression √(-36) has no real square roots.

However, we can express the square root of -36 using imaginary numbers.

By definition, the imaginary unit "i" is equal to the square root of -1. Using this definition, we can rewrite √(-36) as:

√(-36) = √(36) × √(-1) = 6i

Therefore, the two square roots of -36 are 6i and -6i, where i is the imaginary unit.

Answer:

5

Step-by-step explanation:

The slope will be the constant amount that the cost increases by each month.

In this situation, 5 is the slope, because he has to pay $5 each month.

35 is not the slope, and is instead the y intercept. This is because this is the cost at 0 months, since it is the membership fee.

So, the correct answer is 5.

The experiment was not double-blind because volunteers were randomized into the two groups. The correct option is c.

A type of clinical experiment where neither the research team nor the subjects are aware of the treatment or intervention they are receiving until the trial is complete. As a result, the study's findings are less likely to be skewed.

Because neither the participant nor the clinician is aware of who has received what treatment, double-blind studies are regarded as the most trustworthy sort of research. This is done in an effort to lessen bias and the placebo effect.

Both the researchers and the test subjects must be uninformed of who is receiving the treatment and who is receiving a placebo in a double-blind trial.

Therefore, the correct option is c. volunteers were randomized into the two groups.

Answer:

the answer is 85%

Step-by-step explanation:

To find the percentage you will divide:

17 divided by 20 = o.85

Answer:

B. 85%

Step-by-step explanation:

in order to find out her percentage, you want to do 17/20

the reason we do 17/20 and not 20/17 is because 20/17 gives you 1.1, which is both not an option and does not make logical sense

17/20 = 0.85

in order to make this a percentage, multiply 0.85 by 100

0.85 x 100 = 85

so your answer is 85%, or B

Step-by-step explanation:

For all Plato users

Approximately 94437.825 tons of LNG will be produced in May, and approximately 104,489 tons will be produced in October month.

Given that, the production of LNG by an energy company increases by 1.7% each month.

Convert the problem to an equation using the percentage formula: P% * X = Y.

Production in April month=91,307+1.7% of 91,307

=91,307+1.7% ×91,307

=92,859.219 tons

Production in May month=92,859.219×(1+1.7%)

=94437.825 tons

Production in June month=94437.825×(1+1.7%)=96,043 tons

Production in July month=96,043×(1+1.7%)=97,676 tons

Production in August month=97,676×(1+1.7%)=99,336.49 tons

Production in September month=99,336.49×(1+1.7%)=1,01,025.21 tons

Production in October month=1,01,025.21×(1+1.7%)=1,04,489 tons

94437.825 tons of LNG will be produced in May, and 104,489 tons will be produced in October month.

  1. a, b, c - represent growth

  2. b, c, d - represent decay

Step-by-step explanation:

If increasing x results in a larger value, the function represents growth. If it results in a smaller value, the function represents decay.

To answer these questions, you can look at the base and the exponent. When we say "exponent" here, we mean the coefficient of the exponent variable. There are four possibilities:

  growth:

  decay:

Growth questions:

  1.77^x -- growth

  1.5^(x/2) -- growth

  0.5^(-x) -- growth (= 2^x)

  e^(-t) -- decay (e ≈ 2.718)

Decay questions:

Answer:

15 problems were assigned for the weekend.

Step-by-step explanation:

Let x denote the number of problems assigned for the weekend.

Before Sunday, he did 3/5 of the problems, so he is left with (1-3/5)x = 2/5 x of the problems.

On Sunday, he solved 1/3 of what was left of the problems, so he is left with (1 - 1/3)(2/5 x) = (2/3) * (2/5) x = 4/15 x problems.

4/15 x equals 4 because those were the last remaining problems, so we can solve for x:

[tex]\frac{4}{15}x=4\\x = 4 \cdot \frac{15}{4} = 15[/tex]

So 15 problems were assigned for the weekend.
