Answer:

18

Step-by-step explanation:

Multiply 20 by 0.90 (that is 90%)

18 is the answer

Hope this helps :)

Answer:

18

Step-by-step explanation:

Hello there. This problem can be easily solved by setting up a ratio.

This would be as follows

[tex]\frac{90percent}{100}[/tex]  x  [tex]\frac{x}{20 }[/tex]

after solving for x we find that 90% of 20 should be 18.

Hope this helps!

Answer:

b and d

Step-by-step explanation:

Answer:

y = 2x -3

Step-by-step explanation:

to solve for y, simply isolate the y so in this case move 2x to the right side of the equation in which it becomes -y= -2x +3 and then divide by -1 which is beside the -y essentially cause y cannot be negative so then the equation becomes y = 2x -3

Answer:

y=2x-3

Step-by-step explanation:

2x-y=3

-2x on both sides of the equal sign which leaves you with -y=-2x+3

divide both sides by negative 1

y=2x-3

Answer:

9 - 7x - x²

Step-by-step explanation:

-4x+2x2-x²+5-3x = -4x-3x+2x2+5-x²

I arranged the like terms together so it is easier to do the calculations.

-4x-3x+2x2+5-x² = -7x+4+5-x²

Simplify.

-7x+4+5-x² = 9-7x-x²

Answer:

[tex]x^{2} -7x+5[/tex]

Step-by-step explanation:

First, organize it by highest degrees: [tex]2x^{2} -x^{2} -4x-3x+5[/tex]

Then combine like terms: [tex]x^{2} -7x+5[/tex]

Max weight of the crate - the empty crate/ by 35 (the weight of the individual boxes)

850-150=700

700 lbs is the remaining weight available that can be filled with 35 lb boxes, to find out the number of boxes that can be added to the crate, divide 700 by 35.

700/35 = 20

Ernest can put in 20 boxes in the crate.

Answer:

(x,y)=(-2,3)

Step-by-step explanation:

Since both expressions -3x-3 and x+5 are equal to y, set them equal to eachother forming an equation in x

-3x-3=x+5

solve the equation for x

x= -2

substitute the given value of x into the equation y=x+5

y= -2 +5

solve the equation for y

y=3

the possible solution  of the system is the ordered pair (x,y)

(x,y) = (-2,3

check if the given ordered pair is the solution of the system of equations

{3= -3x(-2) -3

{3= -2 +5

simplify the equalitites

{3=3

{3=3

since all the equalitites are true, the ordered pair is the solution of the system

(x,y)=(-2,3)

Hope this helps!! I would really appreciate a brainliest

Answer:

(x+10)/5

Step-by-step explanation:

Given the function

g(x) = 5(x-2)

Open the parenthesis

g(x) = 5x-10

To find the inverse we need to follow the steps;

Step 1; make y as g(x)

y = 5x-10

Step 2; replace y with x;

x = 5y - 10

Step 3; make y the subject of the formula;

x = 5y-10

5y = x+10

y = (x+10)/5

Step 4: substitute y as g^(-1)(x)

g^(-1)(x) = (x+10)/5

Hence the inverse of the function is (x+10)/5

Answer: x+10/5

Step-by-step explanation:

Same as above

Answer:

Yes.

Step-by-step explanation:

Yes, the equation is in standard from because the way standard form is written is: Ax+By=C.

Hope this helps! Have a great day!! （*^w^*）

Given :

The Mad Hat Company must ship two different-sized boxes: The small ones cost them 45 cents each and weigh 6 ounces, and the large ones weigh 25 ounces and cost $1.20 each.

The total shipment this morning weighed 20 pounds 7 ounces and cost $18.45.

To Find :

How many packages of each size were shipped.

Solution :

We know, 1 pound = 16 ounces.

So, 20 pound = 20×16 = 320 ounces.

Let, number of large and small box are l and s.

So,

25l + 6s = 327 ...1)

0.45s + 1.20l = 18.45 ...2)

Solving both the equations, we get :

x = 9 and y = 17

Therefore, package smaller and big size are 17 and 9 respectively .

Hence, this is the required solution.

Heyyyy :)

1- 7 units up 4 down; dil 2

2- clockwise rotation

3- reflection; dil 2

4- Counter-clockwise rotation

Step-by-step explanation:

I'm sorry if you don't understand but when I was writing my notes I shortened it and I don't remember the real wording.

But if you read the problems the two that are very similar are the same but one of the problems says clockwise and the other is counter-clockwise. And the one that is shorter than the other three problems is the reflection; dil 2, and the other is kinda obvious. I hope you understand!!!!!

Byeeeee :)

Answer:

Step-by-step explanation:

For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises. A computer software retailer used a markup rate of 40%.

Answer:

Step-by-step explanation:

x=64 degrees

y=52 degrees

It is an isosceles triangle which has two angles of the same measurement, Pretty easy to figure out.

Answer:

x= 64 ansdy=52

Step-by-step explanation:

Since the 64 line is congruent to the "x" line, it must be 64. A triangle's angles equal 180 so 180-64-64= 2 giving you "y"

Step-by-step explanation:

Answer:

¼x - 20 = -45

¼x = -25

x = -100

Step-by-step explanation:

To solve this we can write it out into an equation. Let's use the variable x for the number Alex is thinking of. Then we can take out each information to see what it means mathematically. We need to see what operation is being done.

"twenty less than one fourth of the number" The second part is using mutiplication, as indicated by "of." So we would write a quarter (one fourth)  times the number (x). The first part is using subtraction, indicated by "less than." This would be expressed by "- 20"

Putting it together:

¼x - 20

"is -45" this is joining the expression to an equation. So this would simply mean " = -45 " Then our equation is:

¼x - 20 = -45

Now we can solve it.

¼x - 20 = -45

¼x = -25

x = -100
