Answers

Answer:

Total number of unemployment in 2018 = 3,276,420

Step-by-step explanation:

Given:

Total number of unemployment in 2017 = 3,766,000

Decreased in unemployment = 13%

Find:

Total number of unemployment in 2018

Computation:

Total number of unemployment in 2018 = Total number of unemployment in 2017 - Decreased in unemployment

Total number of unemployment in 2018 = 3,766,000 - 13%

Total number of unemployment in 2018 = 3,276,420

5 less than twice the length equals 11 as an algebraic equation

Answers

Answer: 2*L - 5 = 11

Step-by-step explanation:

Suppose that we have a rectangle with length L and width W.

Now we know that:

" 5 less than twice the length equals 11"

Then we get:

"twice the length" is written as 2*L

5 less than that is:

2*L - 5

And this is equal to 11, then:

2*L - 5 = 11

This is the algebraic equation we wanted to find,

Find the greatest common factor of 7x and 4x?.

Answers

Answer:

GCF = x

Step-by-step explanation:

The factor decomposition is:

7 * x   for the first term

2 * 2 * x for the second term.

The ONLY common factor is "x", and the maximum power at which it appears in BOTH terms is "1" (one)

Therefore GCF = x

Jenny read 12 pages on Monday, 25 pages on Tuesday and
the remaining pages on Wednesday. On average she read
23 pages per day during these three days. How many pages
did she read on Wednesday?​

Answers

Answer:

32

Step-by-step explanation:

Let Wed pages = x

(12 + 25 + x) / 3 = 23                 Multiply both sides by 3

12 + 25 + x = 3 * 23                  Combine the right

12 + 25 + x = 69

37 + x = 69                                Subtract 37

x = 69 - 37

x = 32

What is the height of a right triangle if its other two sides are 30 centimeters and 10 centimeters long?​

Answers

Answer:

Step-by-step explanation:

It depends on whether the 30 cm side is the hypotenuse, or one of the legs.

If the 30 cm side is the hypotenuse, then the third side is √(30^2-10^2) = √800 = 20√2 cm

If the 30 cm side is one of the legs, then the hypotenuse is √(30^2+10^2) = √1,000 = 10√10 cm

Answers

Answer:

Step-by-step explanation:

y=mx+b

m=(y2-y1)/((x2-x1)

m=(12-7.5)/(120-30)

m=0.05

y=0.05x+b, using point (30,7.5)

7.5=0.05(30)+b

7.5=1.5+b

b=6

y=0.05x+6

If someone answers this and shows work I will give Brainlyest

Answers

Answer:

x = 2

y = 1

Step-by-step explanation:

-2x-3y=-7, y=6x-11

-2x - 3(6x - 11) = -7

-2x - 18x + 33 = -7

-2x - 18x = -40

-20x = -40

x = 2

y = 6(2) - 11

y = 12 - 11

y = 1

Answer:

x = 2, y = 1

Step-by-step explanation:

We have a system of equations:

-2x - 3y = -7

y = 6x - 11

Substitute the given value of y into the equation -2x - 3y = -7

-2x - 3 * (6x - 11) = -7

-20x = -7 - 33

-20x = - 40

x = 2

Substitute the given value of x into the equation y = 6x - 11

y = 6x - 11

y = 6 * 2 - 11

y = 1

Aaron is twice as old as Ryan.In 3 years,the sum of their ages will be 30 years.Find Aaron′s present age ​

Answers

Answer:

If we take Ryan's age as 'x' then we have Aaron's age as '2x'

Now, we have the sum of their ages after 3 years as 30.

So  according to question, we can prepare an equation which is

2x+3+x+3 = 30

= 3x+6 = 30

= 3x = 30-6

= 3x = 24

= x = 24÷3

= x = 8

Thus, Ryan' is 8 years old now.

Now we need to find Aaron's age, and this can be done easily as we have already made an expression fore Aarons age, i.e., '2x'

So 2x= 2×8

= 16.

So we have Aaron's age-16,

Ryan's age-8

Ok so first, let’s see it this way

Aaron: x *2
Ryan: x

So basically 3 in total. Since 30 is already divisible by three we can go from there. Then we will get original age.

30/3 = 10

Aaron = 10 *2
Ryan = 10

This is their ages AFTER the three years. So now, we just subtract to find original age.

20-3= 17
20-3 = 7

Aaron is 17.
Ryan is 7.

Solve for x.
7x= 11.2

Answers

Answer:

X = 1.6

Step-by-step explanation:

Divide 7 on both sides:

7x = 11.2

x = 1.6

X, therefore, is 1.6.

Hope this helps!!

- Kay :)

x= 11.2/7
x= 1.6

7 x 1.6 = 11.2
11.2 = 11.2
