<h2>Explanation:</h2><h2 />

When we say "a is at most b" we mean that "a is less than or equal to b" or "a is not greater than b". So let's solve this problem as follows:

Step 1. Twice the difference of a number and 2

Let's call that unknown number as n. Then, twice the difference of a number and 2 is:

2(n-2)

Step 2. Twice the difference of a number and 2 is at most -27

2(n-2)\leq -27

_________________________________________

So the mathematical form of the statement <em>twice the difference of a number and 2 is at most -27 </em>is:

\boxed{2(n-2)\leq -27}

What is the value of x?<br> 4x − 6 = 18
tensa zangetsu [6.8K]
You need to get rid of -6 by adding 6, you also need to add 6 to 18.

4x = 24

Now you need to get rid of the 4 attached to the variable, you do this by dividing 4 since it is multiplying, also dividing 4 and 24

x = 6

So the value of x is 6

Hope this helps! :)

6. Triangle ABC is rotated 90 degrees counterclockwise and then translated 3 units up to form
joja [24]

Given:

Consider triangle ABC is rotated 90 degrees counterclockwise and then translated 3 units up to form triangle A'B'C'.

To find:

The transformation that can be used to map each point (x,y) on Triangle ABC to its corresponding point on Triangle A'B'C'.

Solution:

If a figure rotated 90 degrees counterclockwise, then

(x,y)\to (-y,x)

P(x,y)\to P_1(-y,x)

If a figure translated 3 units up, then

(x,y)\to (x,y+3)

P_1(-y,x)\to P'(-y,x+3)

If  triangle ABC is rotated 90 degrees counterclockwise and then translated 3 units up to form triangle A'B'C', then the rule of transformation is

(x,y)\to (-y,x+3)

Therefore, the required rule of transformation is (x,y)\to (-y,x+3).

Note: Option are not in proper form.

Taylor earns $5 each time she walks her neighbor's dog.she has already earned $25.write and solve an equation to find out how ma
Vlada [557]

Answer:

Equation: $83=5w+25 and 12 walks more

Step-by-step explanation:

Here is an equation: $83=5w+25

The $83 on the left represents the $83 goal for the bike (or the total amount of money that Taylor needs)

The 5w represents that Taylor earns $5 per time she walks the dog, with the w being the number of walks.

The +25 shows that Taylor has already earned $25 from walking the dog. (Not sure if you need it, but the $25 took 5 dog walks –– 5•5=25)

To solve:

83 = 5w + 25 –– Subtract 25 from both sides to get the variable term alone

58 = 5w –– Divide both sides by 5 to get w alone

11.6 = w –– <u>Round this up to 12</u> because you can't really do 3/5 of a walk (this means Taylor needs to walk the dog 12 more times to earn enough to buy the bike)

Check:

83=5w+25 –– Replace w with 12

83=5(12)+25 –– Multiply

83=60+25 –– Add

83=85 –– <u>This shows she will have $2 left over</u>
