233982

Step-by-step explanation:

Answer:

233,982

Step-by-step explanation:

222840x0.05=11142

222840+11,142= 233,982

No. Because 33 $ is the money deducted from the 60 $. Dawn bought everything for less than 60 $.

So, if Dawn purchases everything on the rack with a 30% discount and 15% coupon the total will indeed make 45%.

We have to take 100% - 45%= 55% to know the reduction number. Let's proceed to the calculations now.

100%= 60 $

1%=60/100

55%= 60/100 × 55 = 33 $

Now NOTE; 33 $ is the money reduced from the 60 $. So, logically, 33 $ isn't the amount which Dawn purchased the whole rack.

To find the amount at which she purchased everything, we need to do,

60 $ - 33 $ = 27 $

Answer:

z = -4050

Step-by-step explanation:

x × y × z

90 × 45 × z

4050 = -z

4050 = -z \ × -1

-4050 = z

Answer: The solution is (3, -2)

This means that x = 3 and y = -2 pair up together.

=====================================================

Explanation:

The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).

-----------------

As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation

y = (-5/3)x + 3

y = (-5/3)*3 + 3

y = -5+3

y = -2

The first equation is confirmed. Let's check the second equation

y = (1/3)x - 3

y = (1/3)*3 - 3

y = 1 - 3

y = -2

Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.

Answer:

Natalie is 12 years and Fred is 28 years

Step-by-step explanation:

lets assume Natalie's age is X and Fred's age is Y

From the first sentence: X+Y = 40

From the second sentence: Y + 4X = 76

lets rearrange the equations

X+Y =40 ....... equation 1

4X+Y=76........ equation 2

To solve both equations, we will have to look for a way to eliminate one of the unknown to leave us with one unknown. since there are two +Y in both equations, we can subtract both equations to eliminate Y. Please note that whatever you do to one of the unknown in this equations applies to all other numbers & alphabets

So: 1. X - 4X = -3X

2. Y - Y = 0

3. 40 -76 = -36

writing the equation as one will be -3X = -36

X = 12

Put X = 12 into any of the equation

By putting X as 12 into equation 1 : 12 + Y = 40

Y = 40 -12 =28

Recall that Natalie is X and Fred is Y

Therefore Natalie is 12 years and Fred is 28 years

be

To crosscheck put in the gotten answers into the equations

X+Y =40 ....... 12 + 28 = 40

4X+Y=76........ 4(12) + 28 = 76

Answer:

-3x²+17x-20

Step-by-step explanation:

When you apply the distributive property (which you did correctly), you simply multiply each number or variable in which you have to distribute it to (which again you wrote correctly) and then you add them all together.

(3x)(-x)=-3x²

+

(3x)(4)=12x

+

(-5)(-x)=5x

+

(-5)(4)=-20

Add those and you will get your answer. Hope this helped :)

Answer:

Equation: 100 = 2x + 4y

There are 9 4 points problems

Step-by-step explanation:

In this case, we know that we have a test that in total, we must sum 100 points. This could be with question of 2 points or questions of 4 points.

We do not know exactly how many questions of 2 or 4 point are, but we can write an equation that could give us an idea.

Let's call "x" the number of questions worth 2 points.

Let's call "y" the number of questions worth 4 points.

All together must give 100 points, therefore, the logic equation to do this is:

Now, for the second part of this problem, we want to know how many 4 points problems would be in the test if we have 32 questions of 2 points. For that, we use the above equation, and solve for y:

100 = 2(32) + 4y

100 = 64 + 4y

100 - 64 = 4y

36 = 4y

Answer:

The solution of the given equations are (3,2).

Step-by-step explanation:

Given equations are :

3d−e=7 ...(1)

d+e=5 ...(2)

Add equations (1) and (2) we get :

3d-e+d+e=7+5

4d = 12

d = 3

Put the value of d in equation (2).

3+e=5

e = 2

So, the value of d = 3 and e = 2. Solution of the given equations are (3,2).

Answer:

we all need help sometimes

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

m∠lon = m∠2 (vertical opposite angles are equal)

m∠lon = m∠1 (corresponding angles are equal).

Therefore; m∠2 = m∠1 (substitution property)

3x + 25 = 7x + 5

Subtracting 5 and 3x from both sides of the equation:

3x + 25 - 5 - 3x = 7x + 5 - 5 - 3x

4x = 20

dividing through by 4:

4x / 4 = 20 / 4

x = 5

Given that:

m∠3 = -2x + 70

substituting x = 5:

m∠3 = -2(5) + 70 = 60

m∠3 = 60°

Therefore:

m∠4 + m∠2 + m∠3 = 180° (substitution)

(155 - 3x) + (7x + 5) + (-2x + 70) = 180

(-3x + 7x - 2x) + (155 + 5 + 70) = 180

2x + 230 = 180

2x = -50

x = -25

Therefore; m∠3 = -2x + 70 = -2(-25) + 70 = 50 + 70

m∠3 = 120°

Answer:

Step-by-step explanation:

Please use " ^ " to indicate exponentiation:

A = x^2 + 9x - 36.  This factors into A = (x + 12)(x - 3).  We can assume that the length of the parallelogram is x + 12 and that the width is x - 3.

Note that if x = 3 the area becomes zero.  So:  x must be greater than 3, so that the (x - 3) factor is positive.

Example:  If x = 4, then the dimensions of the parallelogram are 4 + 12, or 16, and 4 - 3, or 1.  

Answer:

3 and 1

Step-by-step explanation:

To make this equation true you have to fill in the blank spots so x is 3

So I simply multiplied 3 times x which is 3x+ blank is 10

if I want x to be 3 then I fill in the blank for 1

now I do additive inverse to get the x by itself

subtract 1 on both sides

the equation is now 3x=9

Divide 3 in each sides and x=3

Answer:

1x + 7 = 10

-4x + 22 = 10

Step-by-step explanation:

Equations

We are given the following expression:

__x + __ = 10

Where the spaces must be filled with any value that makes x=3 the solution to the equation.

Let's call a and b the variables to fill up the spaces:

ax + b = 10

For x=3, the following equation must stand:

3a + b = 10

Any combination of a and b that makes true the above equation will solve the problem. Let's solve for b:

b = 10 - 3a

Make a=1, thus b = 10 - 3 = 7

So the equation:

1x + 7 = 10

Has the solution x=3

For a = -4, b = 10+12 = 22

Another combination is:

-4x + 22 = 10
