whats 3(x + 2) = 21?
show work please !!​

Answer: = 1/36

Step-by-step explanation:

Answer:

1) 7x-2+5x-10=180

2)16x-2-10=180

3)16x - 12 = 180

16x=192

x=12

Answer:

x <24

Step-by-step explanation:

first cancel negative signs

then transfer 2 to right side

Greetings.

The answer is x > 24.

Explanation:

Solving Inequality is almost the same as equation. However, you have to know one thing about solving an Inequality.

That is whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality.

[tex]-\frac{1}{2}x<-12[/tex]

Reminder that

[tex]-\frac{1}{2}x=-\frac{x}{2}[/tex]

We use negative x above 2 instead (Easier in solving)

[tex]-\frac{x}{2}<-12[/tex]

Then we move 2 to divide -12.

[tex]-x<-12(2)\\-x<-24[/tex]

Because the coefficient for x is in negative. We move -1 to divide -24 as we get 24 (Because negative divide negative = positive)

But remember that "whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality."

So we change from < to > instead.

[tex]x>24[/tex]

[tex]x=0,10[/tex]

Step-by-step explanation:

STEP 1: Move all terms not containing |5−x| to the right side of the equation.

[tex]3|5-x|=15[/tex]

STEP 2: Divide each term by 3 and simplify.

[tex]|5-x|=5[/tex]

STEP 3: Remove the absolute value term. This creates a ± on the right side of the equation because |x|=±x.

5-x=±5

STEP 4: Set up the positive portion of the ± solution.

[tex]5-x=5[/tex]

STEP 5: Solve the first equation for x.

[tex]x=0[/tex]

STEP 6: Set up the negative portion of the ± solution.

[tex]5-x=-5[/tex]

STEP 7: Solve the second equation for x.

[tex]x=10[/tex]

NOTE: The solution to the equation includes both the positive and negative portions of the solution.

[tex]x=0,10[/tex]

Answer:

135 and 135

Step-by-step explanation:

The computation is shown below:

The number of examiners who passed in only one subject is as follows

=  n(E) - n(E ∩M) + n(M) - n(E ∩M)

= (80 - 60 + 70 - 60)%

= 30%

Now the number of students who passed in minimum one subject is

n(E∪M) = n(E) + n(M) -  n(E ∩M)

= 80 - + 70 - 60

= 90%

Now the number of students who failed in both subjects is

= 100 - 90%

= 10% of total students

= 45

So total number of students appeared for this 450

So, those who passed only one subject is

= 450 × 30%

= 135

Now the Number of students who failed in mathematics is

= 100% - Passed in Mathematics

= 100% - 70%

= 30% of 450

= 135

Answer: 4

Step-by-step explanation:

Answer: 110 degrees

Step-by-step explanation:

Similar polygons have the exact same angles. So we can fill in 60 for angle E, because it matches up with angle A.

The angles in a quadrilateral add to 360 degrees.

So 60 + 100 + 90 + Angle H = 360

If we solve for angle H, we get that angle H = 110 degrees.

Answer:

m=5

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

Let's write the equation in the slope-intercept form by solving for y.

y + 2 = 5(x - 1)

y = 5x - 5 - 2

y = 5x - 7

Answer: The slope is 5

Answer:     Tahat= 40.5 marks    Promi =29.5 marks,  Kabi =24.5 marks

Step-by-step explanation:

Step 1

Let the marks be represented as  x+11, x and x-5 for Tahat, Promi and Kabi respectively

and Tahat's marks which was 75% of the sum of Promi and Kabi's marks be expressed as

x+11 = 75/100(x + x-5)  

Step 2 --- Solving

x+11 = 75/100(x + x-5)  

x+ 11 = 3/4(2x-5)

x+11= 6x-15/4

4x+44=6x-15

44+15=2x

x= 59/2= 29.5,

A) x= Promi's  mark was 29.5

B)Promi secured 5 marks more than kabi

Therefore, Kabi's mark was 5 marks less than Promi

= x-5

29.5- 5= 24.5 marks

C)Promi secured 11 marks less than Tahat, Therefore Tahat marks were 11 marks more than Promi

x+11= 29.5 + 11= 40.5

Answer:

The bag costs 1500, while the umbrella cost 500

Step-by-step explanation:

Let the cost of the bag be b and the cost of the umbrella be u

Total cost is;

b + u = 2,000 •••••(i)

From the second part of the question;

b = 5u-1000 ••••••(ii)

Substitute ii into i

5u-1000 + u = 2000

6u = 2000 + 1000

6u = 3000

u = 3000/6

u = 500

To get b, substitute the value of u into equation ii

b = 5(500)-1000

b = 2500-1000

b = 1500
