What is the answer to this problem -2x – 4 < 3x + 21

Start with

Add 2x to both sides:

Subtract 21 from both sides:

Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:

So, the answer is -5 " alt=" x > -5 " align="absmiddle" class="latex-formula">

Suppose that all blocks in a city are the same length. Streets run north and south. They are numbered consecutively, starting with First Street. Avenues run east and west. They are also numbered consecutively, starting with First Avenue. Jerome Walker lives at the corner of Third Street and Twenty-Fourth Avenue. He walks to the bank at Third Street and Eleventh Avenue, to the post office at Tenth Street and Eleventh Avenue, and then to the barbershop on Tenth Street and Twenty-Fourth Avenue. Then Jerome Walker walks home.

How many blocks does Jerome Walker walk?

Answer:

40 blocks

Step-by-step explanation:

Imagine the city is placed on a Cartesian plane grid or graph. The streets count rightwards and avenues count upwards.

Each location can be written as a coordinate or ordered pair in the form (x, y). "x" is the street number and "y" is the avenue number.

Jerome Walker lives at 3rd St. and 24th Ave. He lives at (3, 24).

The bank at 3rd St. and 11th Ave. is at (3, 11).

The post office at 10th St. and 11th Ave. is at (10, 11).

The barbershop at 10th St. and 24th Ave. is at (10, 24).

And again, his home is at (3, 24).

Calculate the number of blocks, or squares on the grid, between each part of his walk. Then, add the numbers together.

(3, 24) to (3, 11): 24-11 = 13

(3, 11) to (10, 11): 10-3 = 7

(10, 11) to (10, 24): 24-11 = 13

(10, 24) to (3, 24): 10-3 = 7

13 + 7 + 13 + 7 = 40

Therefore Jerome Walker walked 40 blocks.

What is 8640minutes in days?(remember ,there are 60minutes in an hour and 24 in a day

There are 60 minutes in an hour. And 24 hours in a day. So logically if you have common math sense. Then you would multiply them together and get the total number of minutes in each day. Then you would divide 8640 (because it was minutes) by the number of minutes in the day and you would get you number which would be 6. Again I literally think that if you had common math sense you would just lowkey understand that. With all sarcasm involved

Two sets of quadratic expressions are shown below in various forms: Line 1: x2 − x − 6 (x + 2)(x − 3) (x + 0.5)2 − 6.25

Line 2: x2 − x − 2 (x + 1)(x − 2) (x − 0.5)2 − 2.25

Which line contains three equivalent expressions?

1)

x²-x-6=(x+2)(x-3)

(x+0.5)²-6.25 =[x²+x+0.25]-6.25

=x²+x-6={x-3}{x+2}

2)

x²-x-2=(x+1)(x-2)

=(x-0.5)²-2.25={x²-x+0.25}-2.25

={x²-x-2}={x+1}{x-2}

x²-x-6=(x+2)(x-3)

(x+0.5)²-6.25 =[x²+x+0.25]-6.25

=x²+x-6={x-3}{x+2}

2)

x²-x-2=(x+1)(x-2)

=(x-0.5)²-2.25={x²-x+0.25}-2.25

={x²-x-2}={x+1}{x-2}

Only number 2 contains three equivalent expressions

Through: (-2,-1), slope= 5/2

If finding the slope, the answer would be

m=3/2

m=3/2

Answer:

y = x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = , thus

y = x + c ← is the partial equation

To find c substitute (- 2, - 1) into the partial equation

- 1 = - 5 + c ⇒ c = - 1 + 5 = 4

y = x + 4 ← equation of line

A dependent linear system has---- solution(s).

Answer:

A dependent linear system has infinite solution(s).Step-by-step explanation:

If a system has at least one solution, it is said to be consistent.

If a consistent system has exactly one solution, it is independent.

If a consistent system has an infinite number of solutions, it is dependent.

If a system has no solution, it is said to be inconsistent.

Answer:

infinitely many

Maggie has 20 buttons which is 4 times more than the 5 zippers she has. 20 is 4 times as many as 5. What is the equation to match this comparison sentence

Answer:

20 = 4 × 5

Step-by-step explanation:

The translation from English is straightforward. "is" means "=". "times" is usually represented by "×" or a raised dot (·).

20 is 4 times 5

translates to

20 = 4 × 5

At a certain concert, 73 % of the audience was under 20 years old. A random sample of n = 146 members of the audience was selected. Find the value of , the mean of the distribution of sample proportions.

Answer: p = 0.73

Step-by-step explanation:

Given that,

73% of the audience was under 20 years old :

so, probability (p) = 0.73

n = 146

Mean of the distribution of sample proportion = ?

According to central limit theorem,

np(1-p) ≥ 10

146 × 0.73(0.27) ≥ 10

28.77 ≥ 10

∴ Central limit theorem assumes that the sample distribution of the sample proportion is normally distributed.

Hence, the mean of the distribution of sample proportion:

μ = p = 0.73

A soccer team played 160 games and won 65 percent of them.How many games did it win? Answers 94 104 114 124

Answer:

104

Step-by-step explanation:

We require to calculate 65% of 160

65% = = 0.65

multiply 160 by 0.65 for number of wins

number of wins = 0.65 × 160 = 104
