they will approximately require 4.4 days to complete the remaining work together.

Ann alone take = 10 days to translate a document.

Work done in 1 day by Ann = 1 / 10

In 2 days = 2 / 10

Work left = 8 / 10

Now, Ben alone take = 12 days to translate a document.

Work done in 1 day by Ben = 1 / 12

We will now use addition.

Combined work of both Ann and Ben in 1 day = 1 / 10 + 1 / 12 = 11 / 60

Time taken to complete the rest of the work = 8 / 10 ÷ 11 / 60

= 48 / 11 = 4.4 days.

Therefore, they will approximately require 4.4 days to complete the remaining work together.

*Note, my question had Ann as 8 days and Ben as 12, so adjust accordingly*

Answer:

3 3/5

Step-by-step explanation:

After 2 days, 1/4 are done so 3/4 are left

1/8 + 1/12 = 10/48

3/4 ÷ 10/48

3/4 × 48/10 = 144/40 = 3 24/40 = 3 6/10 = 3 3/5

Answer:

y = mX - mx

Step-by-step explanation:

X - (y/m) = x

Multiply everything by m

(m)X - (y/m)(m) = x(m)

mX - y = mx

-mX        -mX

-y = mx - mX

Divide both sides by -1

-y = mx - mX

÷ -1       ÷ -1

y = -mx + mX

or

y = mX - mx

The numbers are 77 , 177 and 308 .

Numbers are the building blocks in mathematics. It is an arithmetic value that is used to represent a quantity. Real numbers , integers , natural numbers, whole numbers , irrational numbers are are various types of numbers.

Let us consider the first number to be x . Then the second number is 4x+100 , and the third number is 100 more than the first number. Therefore the the sum of the three numbers will be:

x+4x+(x+100)=6x+100

Now the sum of all the numbers is 562.

Therefore we can write a linear equation in x to find the values of x.

∴ 6x+100=562

or, 6x = 562 - 100

or, 6x = 462

or, x = 462 ÷ 6

or, x = 77

Therefore the second number is 4x = 4 × 77 = 308 and the third number is x + 100 = 77 + 100 = 177 .

So the numbers are 77 , 177 and 308 .

The statement that explains why this is true is (d) dividing both sides of Equation A by -3 gives x + 7 = − 8 .

The equations are given as

In equation A, we have

-3(x + 7) = 24

Divide both sides of this equation by -3

So, we have

-3(x + 7)/-3 = 24/-3

Evaluate the quotient

So, we have

x + 7 = -8

The above equation is the same as equation B

Hence, the statement that explains why this is true is (d) dividing both sides of Equation A by -3 gives x + 7 = − 8 .

Answer:

0.035 kg

Step-by-step explanation:

(0.07 kg / 1 litre) x (0.5 litre)

= 0.035 kg

Notice how the units of litres cancel and all you are left with is units of kg which is what we want. Another way of solving this problem is via logic. If 1 litre of water is needed for 0.07 kg salt, then half a litre of water (0.5) would need half of the amount needed by 1 litre water so (0.07/2) = 0.035 kg

we get that option (d) 2 x + 3 is a factor of the quadratic function g (x)= a x² - 7 x - 15.

We are given a quadratic function:

g (x)= a x² - 7 x - 15

We also know that 5 is a root for it.

So, we get that:

a (5)² - 7 (5) - 15 = 0

25 a - 35 - 15 = 0

25 a - 50 = 0

25 a = 50

a = 50 / 25

a = 2

So, the function becomes:

g (x)= 2 x² - 7 x - 15

Now factorizing the function:

2 x² - 7 x - 15

2 x² - 10 x + 3 x - 15

2 x ( x - 5 ) + 3 ( x - 5 )

( 2 x + 3 ) ( x - 5 )

Therefore, we get that option (d) 2 x + 3 is a factor of the quadratic function g (x)= a x² - 7 x - 15.

Answer:

a = 130

b = 50

Explanation:

Analyze that the angles a and b lies on a straight line summing up to 180°.

Equation's:

make 'a' subject in eq 1

a + b = 180

a = 180 - b

substitute this into eq 2

a - b = 80

(180 - b) - b = 80

180 - 2b = 80

-2b = 80 - 180

-2b = -100

b = 50

Find value of 'a':

a = 180 - b

a = 180 - 50

a = 130

Answer:

a = 130°, b = 50°

Step-by-step explanation:

The given equation is,

→ a - b = 80°

→ a + b = 180°

The equation we form is,

→ (a + b) + (a - b) = 180 + 80

Now the required value of a will be,

→ (a + b) + (a - b) = 180 + 80

→ (a + a) + (b - b) = 260

→ 2a = 260

→ a = 260/2

→ [ a = 130° ]

Hence, the value of a is 130°.

Then the required value of b will be,

→ a + b = 180

→ 130 + b = 180

→ b = 180 - 130

→ [ b = 50° ]

Hence, the value of b is 50°.

The equation of the linear function in slope intercept form is f(x) = -2x + 1

The table can be used to write linear equation in slope intercept form.

Therefore, the equation of the linear function in slope intercept form is as follows:

y = mx + b

where

Therefore,

m = 3 - 5 / -1 + 2

m = - 2 / 1

m = -2

Therefore, the y-intercept can be solved as follows;

using (0, 1)

y = -2x + b

1 = -2x + b

1 = -2(0) + b

b = 1

The place value of the digit "6" in the given number 760,000 is Ten thousand's i.e., sixty thousand.

Definition of place value

The numerical value of the digit in the given number is based on its position in the number.

The place values are:

Hundred thousands(Hth) - 100,000

subtract the values(1372-648)

The measures of the angles are <1 = 85, <2 = 105, <3 = 85 and <4 = 105

The diagram that completes the question is added as an attachment

From the diagram, we have

<1 + <2 = 180 degrees --- supplementary angles

Given that

<2 - <1 = 30 degrees

Add the above equations

So, we have

2<2 = 210

Divide both sides by 2

<2 = 105

Substitute <2 = 105 in <2 - <1 = 30

So, we have

105 - <1 = 30

Evaluate

<1 = 85

Also, we have

<3 = <1

<4 = <2

This means that

<3 = 85

<4 = 105

Hence, the measures of the angles are <1 = 85, <2 = 105, <3 = 85 and <4 = 105

Answer:

Table 3 → 5 (5× 14=70)

The equation relating to the total cost and number of students attending the park is $22.5x = y

According to the question we have been given that

Total money paid by Mrs. Jameson = $202.50

Total number of the students = 9

Let the amount of one student to visit the amusement park be X

Thus first we have to find the value of X by following equation,

          9X = $202.50

Solving for X we get,

           X = 202.50/9

           X = $22.5

That is amount for one student is = $22.5

Now we will solve the second part

Let the total cost be represented as y

Let the number of students attending the park be represented as x

Then the equation related to total cost and number of students is given as

                  $22.5x = y
