Answer:

14 and simplify to 4

Step-by-step explanation:

Add 1010 to both sides.

x=4+10

x=4+10

2 Simplify  4+104+10  to  1414.

x=14

x=14

x−10=4

1 Let x=14x=14.

14-10=4

14−10=4

2 Simplify  14-1014−10  to  44.

4=4

4=4

Answer:

x=60

Solve for x by simplying both sides of the equation,then isolate the variable.Im not sure if this help but i tried.

Answer:

4,6 ,7,8

Step-by-step explanation:

Answer:

4

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:

we all need help sometimes

Step-by-step explanation:

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:

Its good and yours? ill try to answer ur question i might not know lol

Step-by-step explanation:

Answer:

hello

Step-by-step explanation:

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: 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:{ x,y } = { - 2, - 3 }

Step-by-step explanation: 4x = 2y - 2                                                                      

x = y/2 - 1/2                  

3. (y   /2 -  1/2 ) + 2y  =  - 12  

7y/2 =  - 21/2  

7y =   -  21    

x =   y/2 - 1/2  

   y =  - 3    

x = (/2) ( - 3 ) - 1/2 = - 2

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

Answer:

Step-by-step explanation:

The area of the circle will be 3.14 feet .

Find the area of a circle with a diameter of 2 feet. Use 3.14 for π.

★Given,

→ Diameter = 2 feet

→ Circumference = 2/2 = 1 feet

★Now,

→Area of a circle = πr²

→ = 3.14 × 1 × 1

→ = 3.14 feet

Hence , the circumference is 3.14 feet.

Answer:

Option D. y = 5x + 1

Step-by-step explanation:

From the question given above, the following data were:

Input (x) >>>>>> Output (y)

0 >>>>>>>>>>>> 1

1 >>>>>>>>>>>> 6

2 >>>>>>>>>>>> 11

3 >>>>>>>>>>>> 16

4 >>>>>>>>>>>> 21

To know the the correct answer to the question, we shall apply the equation given in each option to see which will satisfy the table. This can be obtained as follow:

For Option a

y = 3x + 3

x = 0

y = 3(0) + 3

y = 0 + 3

y = 0

y = 3x + 3

x = 1

y = 3(1) + 3

y = 3 + 3

y = 6

For Option b

y = 5x – 4

x = 0

y = 5(0) – 4

y = 0 – 4

y = – 4

y = 5x – 4

x = 1

y = 5(1) – 4

y = 5 – 4

y = 1

For Option c

y = 10x – 9

x = 0

y = 10(0) – 9

y = 0 – 9

y = – 9

y = 10x – 9

x = 1

y = 10(1) – 9

y = 10 – 9

y = 1

For Option d

y = 5x + 1

x = 0

y = 5(0) + 1

y = 0 + 1

y = 1

y = 5x + 1

x = 1

y = 5(1) + 1

y = 5 + 1

y = 6

From the illustrations made above, only option d satisfy the table. Thus, option d gives the correct answer to the question.
