5). x = 18                       5). Division property of equality

Question (4)

Equations are,

5x + 10 = 30 ------(1)

5(x + 10) = 30 ------(2)

From equation (1),

5x + 10 = 30

5x = 30 - 10

x = 4

From equation (2),

5(x + 10) = 30

(x + 10) = 6

x = 6 - 10

x = -4

Therefore, solutions of both the equations are different.

Answer:

  5%

Step-by-step explanation:

Assuming the measurement is rounded to the nearest pound, there is the potential for the reported value to differ by 1/2 pound from the measured value. The precision of the measurement is thus ...

  (0.5 lb)/(10.0 lb) = 5/100 = 5%

__

Unless we know the cat's actual weight, we cannot determine the error in the measurement. If the cat actually weighs 10 pounds, the error is 0%.

Answer:

PS = 26 units

Step-by-step explanation:

Perimeter of rectangle = 94

2(4z - 2 + 3z) = 94

2(7z - 2) = 94

14z - 4 = 94

14z = 94 + 4

14z = 98

z = 98/14

z = 7

QR = 4z - 2 = 4*7 - 2 = 28 - 2 = 26

PS = QR (Opposite sides of rectangle)

PS = 26 units

Answer:

[tex]x=\frac{-2m-10}{-2m-7}[/tex]

Step-by-step explanation:

Step 1: Write out equation

3x = (2x - 2)(m + 5)

Step 2: FOIL

3x = 2xm + 10x - 2m - 10

Step 3: Subtract 2xm on both sides

3x - 2xm = 10x - 2m - 10

Step 4: Subtract 10x on both sides

3x - 2xm - 10x = -2m - 10

Step 5: Factor out x

x(3 - 2m - 10) = -2m - 10

Step 6: Combine like terms in parenthesis

x(-2m - 7) = -2m - 10

Step 7: Divide both sides by -2m - 7

[tex]x=\frac{-2m-10}{-2m-7}[/tex]

Answer:

235=30x-25

Step-by-step explanation:

235+25=30x-25+25

260=30x

260/30=30x/30

x=8.66 or 9 weeks

The equation is 30x + 25 = 235. And the number of weeks will be 7.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

Greg is saving to purchase a tablet that costs $235. He as of now has $25 set aside. Every week, Greg procures $15 looking after children and $25 as a clerk, however, he burns through $10 on snacks.

Let x be the number of weeks. Then the equation is given as,

25x + 15x - 10x + 25 = 235

Simplify the equation, then the number of weeks is given as,

25x + 15x - 10x + 25 = 235

30x = 235 - 25

30x = 210

x = 210 / 30

x = 7 weeks

The equation is 30x + 25 = 235. And the number of weeks will be 7.

Answer:

there is no sufficient evidence to prove that viscosity is not 3000

Step-by-step explanation:

Let's state the hypothesis.

Null hypothesis; H0: μ = 3000

Alternative hypothesis; μ ≠ 3000

The sample mean is;

x = (2781 + 2900 + 3013 + 2856 + 2888)/5 = 2887.6

Standard deviation σ = √variance = √[(2781 - 2887.6)² + (2900 - 2887.6)² + (3013 - 2887.6)² + (2856 - 2887.6)² + (2888 - 2887.6)²)(1/(5 - 1))]

σ = √((1/4)(11363.56 + 153.76 + 15725.16 + 998.56 + 0.16)

σ = 84.026

Formula for test statistic is given as;

t = (x - μ)/σ

t = (2887.6 - 3000)/84.026

t = -1.338

From online p-value calculator from t value attached, using DF = 5 - 1 = 4, two tail and a significance level of 0.05,we have;

The p-value is 0.251896.

This is greater than the significance level of 0.05.

Thus, we will fail to reject the null hypothesis and conclude that there is no sufficient evidence to prove that viscosity is not 3000

Answer:

B: (5,1)

Step-by-step explanation:

So we have the system of equations:

[tex]x+y=6\text{ and}\\y+4=x[/tex]

We can solve this system using substitution.

Substitute the second equation into the first. Use x. So:

[tex](y+4)+y=6[/tex]

Combine like terms:

[tex]2y+4=6[/tex]

Subtract 4 from both sides:

[tex]2y=2[/tex]

Divide both sides by 2:

[tex]y=1[/tex]

So, the value of y is 1.

To find x, substitute this back into the second equation:

[tex]y+4=x[/tex]

Substitute 1 for y:

[tex]1+4=x[/tex]

Add:

[tex]x=5[/tex]

Therefore, our answer is (5,1).

The answer is B.

Answer:

5/136

Probability is the chance of an event happening.

Probability = (Favorable outcome)/(total outcome)

P(r and n) = 2/17 × 5/16

=(2 × 5)/(17 × 16)

= 10/272

= 5/136

Answer:

5/136, or about 3.68%

Step-by-step explanation:

There are 17 total books on the bookshelf and only two of them are reference books, so the probability that you randomly grab a reference book is 2 out of 17, or 2/17.

Now that you took out a reference book (and did not put it back) there are 16 books on the bookshelf and you know five of them are nonfiction. That means the probability of getting a nonfiction book on your second grab is 5/16.

To find the probability that both of these events happen, you multiply the two fractions together.

2/17 x 5/16 = 10/272, which can reduce to 5/136, or about 3.68%

Answer:

A conditional statement is false if hypothesis is true and the conclusion is false.

Step-by-step explanation:

Conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.

Reasoning in maths is the process of applying logical and critical thinking to a mathematical problem in order to work out the correct strategy to use  in reaching a solution

A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.

For this conditional statement, P is called the hypothesis and Q is called the conclusion.

“If P then Q” means that Q must be true whenever P is true.

We have a conditional statement If it is raining, we will not play.

Let, P: It is raining and Q: we will not play.

Then; If P is true, that is, it is raining and Q is false, that is, we played, then the statement P implies Q is false.

Hence,  conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.

Answer:

(-1, -4.8)

Step-by-step Explanation:

Let the point be P, which is 3/10 of the way from A to B. This means, it divides P into AP and PB in the ratio, 3:10 = AP/PB = 3/10.

Apply the formula for internal division to find the coordinates which is given as:

[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]

[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]

Where,

[tex] A(-4, -8) = (x_1, y_1) [/tex]

[tex] B(9, 6) = (x_2, y_2) [/tex]

[tex] m = 3, n = 10 [/tex]

Plug in the necessary values to find x and y coordinates for point P

[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]

[tex] x = \frac{3(9) + 10(-4)}{3 + 10} [/tex]

[tex] x = \frac{27 - 40}{13} [/tex]

[tex] x = \frac{-13}{13} [/tex]

[tex] x = -1 [/tex]

[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]

[tex] y = \frac{3(6) + 10(-8)}{3 + 10} [/tex]

[tex] y = \frac{18 - 80}{13} [/tex]

[tex] y = \frac{-62}{13} [/tex]

[tex] y = \frac{-62}{13} [/tex]

[tex] y = -4.8 [/tex]

The coordinates of the point 3/10 of the way from A to B are (-1, -4.8)

Divide both sides of the equation by 3.4

[tex] \frac{3.4x}{3.4} = \frac{17.34}{3.4} [/tex]

The series converges, since |8/9| = 8/9 < 1.

Let [tex]S_n[/tex] denote the n-th partial sum of the series,

[tex]S_n=\displaystyle\sum_{k=0}^n\left(\frac89\right)^k[/tex]

[tex]S_n=1+\dfrac89+\left(\dfrac89\right)^2+\cdots+\left(\dfrac89\right)^n[/tex]

Multiply both sides by 8/9:

[tex]\dfrac89S_n=\dfrac89+\left(\dfrac89\right)^2+\left(\dfrac89\right)^3+\cdots+\left(\dfrac89\right)^{n+1}[/tex]

Subtract this from [tex]S_n[/tex] to eliminate all but the first term in

[tex]S_n-\dfrac89S_n=1-\left(\dfrac89\right)^{n+1}[/tex]

Solve for [tex]S_n[/tex]:

[tex]\dfrac19S_n=1-\left(\dfrac89\right)^{n+1}[/tex]

[tex]S_n=9-9\left(\dfrac89\right)^{n+1}[/tex]

As [tex]n\to\infty[/tex], the exponential term vanishes, so that

[tex]\displaystyle\lim_{n\to\infty}S_n=\sum_{k=0}^\infty\left(\frac89\right)^k=\boxed{9}[/tex]
