I feel like this is a trick question

----

2x + 3 - 4 = 5x - 7

=> 2x + 3 - 4 + 7 = 5x

=> 3 - 4 + 7 = 5x - 2x

=> 3 - 4 + 7 = 3x

=> -1 + 7 = 3x

=> 6 = 3x

=> 6/3 = x

=> 2 = x

Answer:

11/3

Step-by-step explanation:

x=1, R=39, y=?

R=6x + 9y

(substitute the parameters into the equation)

39=6(1) + 9y

39= 6 + 9y

(collect like terms)

39 - 6 =9y

33=9y

(divide both sides by 9)

33/9=9y/9

11/3=y

therefore, y= 11/3

Answer:

That’s easy it is 282

Step-by-step explanation:

He will now have 282 bucks altogether.

Step-by-step explanation:

We already know that he has 237 bucks before his birthday, but now he has an additional 45 bucks that he got from his birthday. With this, you can create an equation that looks like this: 237+45. You then solve the equation by adding 45 to 237, which gets you 282 bucks altogether.

Answer:

x = 7

If a is parallel to b, then 9(7) + 11 = 74.

Step-by-step explanation:

We don't know if the lines are parallel, so we need to see what x is in 9x + 11 = 74, then substitute that value for x in the equation. If both sides are true, the two lines are parallel.

9x + 11 = 74

Step 1: Subtract 11 from both sides.

9x = 63

Step 2: Divide both sides by 9.

x = 7

To make sure, let's substitute 7 for x in the earlier equation.

9(7) + 11 = 74

Step 3: Multiply 9 by 7 to get 63.

63 + 11 = 74

Step 4: Add 11 to 63 to get 74.

74 = 74

The two sides are equal, so a and b are parallel. The definition of a converse is the reverse of a conditional statement. As a result, the converse here is "If a is parallel to b, then 9(7) + 11 = 74."

Answer:

Test score of 75.7.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The results are normally distributed with a mean test score of 60 and a standard deviation of 8.

This means that [tex]\mu = 60, \sigma = 8[/tex]

Calculate the test score above which 2.5% of all test scores lie.

Above the 100 - 2.5 = 97.5th percentile, which is the value of X when Z has a pvalue of 0.975, so X when Z = 1.96.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.96 = \frac{X - 60}{8}[/tex]

[tex]X - 60 = 8*1.96[/tex]

[tex]X = 75.7[/tex]

Test score of 75.7.

Answer:

[tex]P=24\sqrt{x}[/tex] and [tex]A=36x[/tex]

Step-by-step explanation:

To find the perimeter of the triangle, you have to add all the sides of the triangle. So, we get:

[tex]P=8\sqrt{x} +7\sqrt{x} +9\sqrt{x}[/tex]

Combine like terms, meaning the numbers with [tex]\sqrt{x}[/tex]

[tex]P=24\sqrt{x}[/tex]

To find the area of the triangle, we will use the formula [tex]A=\frac{1}{2} bh[/tex], where b is the base and h is the height

The base is: [tex]9\sqrt{x}[/tex]

The height is: [tex]8\sqrt{x}[/tex]

Plug and chug:

[tex]A=\frac{1}{2} *9\sqrt{x} *8\sqrt{x}[/tex]

[tex]A=\frac{1}{2} *72x\\A=36x[/tex]

Answer:

2.68 hours

Step-by-step explanation:

Answer:

[tex] x = \frac{a - c}{b}[/tex]

Step-by-step explanation:

[tex]a = bx + c \\ \\ a - c = bx \\ \\ \orange{ \bold{x = \frac{a - c}{b}}} [/tex]

Step-by-step explanation:

Since f(x) is "2x + 1" and g(x) is "x2 - 7" then f(x) + g(x) [which is the same as (f + g)(x)] is "2x + 1" + "x2 - 7" which is 2x + 1 + x2 - 7 or x2 + 2x - 6

So (f + g)(x) = x2 + 2x - 6

is it right? i hope it is

Answer:

Option d is the correct answer.

Step-by-step explanation:

tan A = 24/7

Answer:

d.) [tex]\frac{24}{7}[/tex]

Step-by-step explanation:

using the sohcahtoa method, where tan A = [tex]\frac{opposite}{adjacent}[/tex], our opposite side is 24, and our adjacent side is 7. our hypotenuse, the longest side, is 25. therefore, we get: d.) 24/7

Answer:

x =45

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

3x+45 = 180

Subtract 45 from each side

3x+45-45 =180-45

3x= 135

Divide by 3

3x/3 = 145/3

x =45

Answer:

T = 67.5

V = 22.5

Step-by-step explanation:

The Sum of triangle angles = 180

180 = W + T + V

180 = 90 + 3X + X

X = 22.5

Answer: 54 feet.

Step-by-step explanation:

Ratio between a tree's height and its shadow's length = x : 72ft

Ratio between man's height and his shadow's length = 6ft : 8ft = 3 : 4

In order to solve this problem, we have to cross multiply the two ratios (image)

So, 4x = 216.

By solving this equation we learn that x = 54ft

So, the tree is 54 feet tall.

Answer:

a = 6 and b = 36

Step-by-step explanation:

Set up equations:

b = 30 + a

b = 6a

Subtract the two equations:

b = 6a

- (b = 30 + a)

5a - 30 = 0

5a = 30

divide both sides by 5

a = 6

Plug a = 6 into the original equation:

b = 30 + 6

b = 36

you could also do:

b = 6 * 6

b = 36

Step-by-step explanation:

651.75÷5.5= 118.50

Answer:

It doesn't make sense

Step-by-step explanation:

Given

Statement: .... at a speed of 35 miles .....

Required

Does it make sense?

In motion, speed is measured in km/h, m/s, miles per hour (depending on context) while distance is measured in km, m or miles.

However, the given statement mention the unit of speed to be miles which is incorrect.

Hence, we can conclude that the statement does not make sense.

A correct statement would be: I drove at a speed of 35 miles per hour .......
