Answer:

for 1) x<-3

for 2) click on the first two

for 3) an open circle with the line pointing left

for 4) x <_ -3

for 5) click the last 3

for 6) a closed circle and the arrow going to the right at -3

for 7) an open circle as it cannot be that number so an open circle on -3 with the arrow pointing right

Step-by-step explanation:

hope that helps

Step-by-step explanation:

I will only do number 1 to help you through this, any questions about the rest just ask!

1. 11 + (20 - 13)

Always start with the parentheses, so first, you will subtract 20 - 13 which will give you 7, with the 7 you will add it to the 11 because that's a leftover number, so you would have to add 11 + 7 which would equal 18.

I usually remember this:

Please Excuse My Dear Aunt Sally,

It stands for

P =Parentheses

E= Exponents

M =Multiplication

D = Division

A = Addition

S = Subtraction

------

Always go in order, that's why I said "Always start with the parentheses" because it's in the first place.

The number of digits is an illustration of combination, and there are 40,000 possible codes that start with a prime number that Genevieve could  create

How to determine the number of digits?

The given parameters are:

Length = 5

First digit = Prime number (2, 3, 5, and 7)

This means that the first digit can be any of the 4 prime numbers, while the other four digits can be any of the 10 digits 0 - 9

So, the number of codes is

Code = 4 * 10 * 10 * 10 * 10

Evaluate

Codes = 40,000

Hence, there are 40,000 possible codes that start with a prime number that Genevieve could  create

Answer:

12n + 8

Step-by-step explanation:

Distributive property of multiplication over addition:

a(b + c) = ab + ac

4(3n + 2) = 12n + 8

less than 20 inches yeyeyeyeyeyeyeyeyey

Answer:

A). ∠ 1 \angle 1 ∠1 and ∠ 8 \angle 8 ∠8 are a pair of alternate exterior angles.

B). ∠1 and ∠5 are a pair of corresponding angles. Similarly, ∠2 and ∠6, ∠3 and 7, and ∠4 and ∠8

C). ∠3 ≅ ∠60°

Step-by-step explanation:

A) both angles are located outside lines s and h, are not adjacent to each other, and are on opposite sides of the transversal.

B).   The Corresponding Angles Postulate states that if k and l are parallel , then the pairs of corresponding

C). are also corresponding angles.

D)

For example, ∠4 and ∠6 are corresponding angles, therefore they are congruent. Other pairs of corresponding angles include ∠3 and ∠5, ∠1 and ∠7, and ∠2 and ∠8. Vertical Angles are formed by angles that are opposite of each other.

Answer:

6.3

Step-by-step explanation:

[tex]c^{2} - a^{2} = b^{2} \\7^{2} = 49\\3^{2} = 9\\49-9 = 40\\\sqrt{40} = 6.32[/tex]

Answer:

[tex] \sf \: x = - 20[/tex]

Step-by-step explanation:

Given equation,

→ 3x + 5 = 2x - 15

Now the value of x will be,

→ 3x + 5 = 2x - 15

→ 3x + 5 - 2x = -15

→ 3x - 2x = -15 - 5

→ x = -(15 + 5)

→ [ x = -20 ]

Hence, the value of x is -20.

Answer: The next number in the quotient is  2

Step-by-step explanation:  Sorry for the messy handwriting

Answer: hey i think the answer is x=5  y=15

Step-by-step explanation: because 3 times 5 is 15 and 2 times 15 is 30 so then you add and it equals the right number the same goes for the one under it

Answer:

use math.way

Step-by-step explanation:

bc im confused too lol

:)

Answer:

I have explained below

Brief explanation:

To divide fractions take the fraction you're dividing by and turn it around. Then replace the division sign with a multiplication sign.

This is how it works - I'll illustrate with an example

[tex]\frac{1}{2} :\frac{2}{3}[/tex]

[tex]\frac{1}{2} : \frac{3}{2}[/tex]

[tex]\frac{1}{2} *\frac{3}{2}[/tex]

now just multiply over

[tex]\frac{1*3}{2*2}[/tex]

[tex]\frac{3}{4}[/tex]

300-180=120 meaning Amy had 180 dollars in her piggy bank

Answer:

$2431

Step-by-step explanation:

First, we have to find the area of the rectange which is 221ft² because the formula for finding the area of a rectangle is length x width. Now since we know that each square ft is equal to $11, we have to multiply     11 x 221 which gives us our answer 2431. Now we just add the dollar sign in front and it become $2431!

Answer:

Answer:

55

Step-by-step explanation:

A straight line measures at 180 degrees

They gave you 125 and x

Because it's on the same line, we can make the equation

125 + x = 180

Subtracting 125 from both sides gets X alone

x = 180-125

x = 55

Answer:

The expression d - 0.75d finds the sale price of the game if the original price is d dollars by subtracting 75% of the original price from the original price.

=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=

The expression 0.25d finds the sale price of the game if the original price is d dollars by multiplying the original price by 25%.

=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=

In both expressions, d represents the original price of the game. The first expression subtracts 75% of the original price, represented by 0.75d, from the original price to find the sale price. The second expression multiplies the original price by 25%, represented by 0.25, to find the sale price.

=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=
