Given that,

The equations : 2f-5g=-9  and -7f+3g=4

To find,

The solution of the above equations.

Solution,

We have,

2f-5g=-9  ....(1)

-7f+3g=4 ......(2)

Multiply equation (1) by 7 and equation (2) by 2.

14f-35g=-63  ....(3)

-14f+6g=8 ......(4)

Add equation (3) and (4)

14f-35g -14f+6g = -63 + 8

-29g = -55

g = 55/29

g = 1.89

Put the value of g in equation (1).

2f-5(1.89)=-9

2f = -9+5(1.89)

f = 0.225

Hence, the solution of the above equations are g = 1.89 and f = 0.225.

Answer:

The height of the telephone pole is of 408 inches = 34 ft.

Step-by-step explanation:

Each foot has 12 inches.

A 36 inch post cast a shadow of 24 inches.

This means that the shadow is [tex]\frac{24}{36} = \frac{2}{3}[/tex] of the real height.

At the same time a telephone pole cast a shadow of 22 ft 8 in.

Each feet has 12 inches, so it has:

22*12 + 8 = 272 in.

2/3 of the real height is 272 in. So

[tex]\frac{2h}{3} = 272[/tex]

[tex]h = \frac{272*3}{2}[/tex]

[tex]h = 408[/tex]

The height of the telephone pole is of 408 inches = 34 ft.

Answer:

3x+20y

Step-by-step explanation:

First write down the expression.

5(x + 5y) - {2x – [3x – 3(x – 2y) + y]}

Now, the first thing you would have to do is the first parenthesis

5(x+5y)

5x+25y

So far, the expression looks like this: 5x+25y - {2x – [3x – 3(x – 2y) + y]}

No we would do the smallest parenthesis in the expression.

Which is: (x – 2y)

But since there is nothing to simplify, we move on

Next one is  [3x – 3(x – 2y) + y]

We have to do 3(x-2y) first

This is equal to: 3x-6y

So far, the expression looks like this:5x+25y - {2x – [3x – 3x-6y + y]}

The next step is still in the other parenthesis up top

Which is: [3x – 3x-6y + y]

We have to add up the x's and y's

Which is -5y

Our expression now looks like this:5x+25y - 2x-5y

Since we don't have anymore parenthesis, we look for the same letter and add or subtract them.

We have to do 5x-2x=3x

25y-5y=20y

So that means our final answer is :3x+20y

Hope this answer is correct!

Step-by-step explanation:

The remainder of a division is the whole number, after the complete division. The expression that finds the last digit of 1327 is: [tex]X \% 10[/tex]

Given that:

[tex]X = 1327[/tex]

To do this, we simply test the given options.

[tex]X \%2 = 1327 \% 2[/tex]

When 1327 is divided by 2,

The result is 663, remainder 1

So, we have:

[tex]X \%2 = 1[/tex]

[tex]X \%3 = 1327 \% 3[/tex]

When 1327 is divided by 3

The result is 442, remainder 1

So, we have:

[tex]X \% 3 = 1[/tex]

[tex]X \% 5 = 1327 \% 5[/tex]

When 1327 is divided by 5

The result is 265, remainder 2

So, we have:

[tex]X \% 5 = 2[/tex]

[tex]X \% 10 = 1327 \% 10[/tex]

When 1327 is divided by 10

The result is 132, remainder 10

So, we have:

[tex]X \% 10 = 7[/tex]

[tex]X \% 100 = 1327 \% 100[/tex]

When 1327 is divided by 100,

The result is 13, remainder 27

So, we have:

[tex]X \% 100 = 27[/tex]

Hence, the expression that finds the last digit is: [tex]X \% 10[/tex]

Because the result is 7

(4x * 4x * 4) * (4x * 4x * 4 )

(16x * 4 ) * ( 16x *4)

Answer:

The distance of Jack's Father's work from home in miles is 45 miles.

Step-by-step explanation:

a) Data and Calculations:

Normal time taken by Jack's father to drive to work = 30 minutes

Time taken when traffic is bad = 1 hour longer

Speed when traffic is bad = 30 mph slower

Distance covered when traffic is bad, with time taken as 1 hour 30 minutes = time * speed = 1.5 * 30 = 45 miles

b) Jack's father normally drives at 90 mph (45 *2), this is why it normally takes him 30 minutes between his home and workplace when the traffic is not bad.  However, when traffic is bad, it takes him one hour longer and he drives at 30 mph slower.
