A father is 20 years older than his son. Five years ago,he was three times as old as his son was.Find their present ages​

Answers

Answer:

Dad=35, Son=15

Step-by-step explanation:

Well since the dad is 20 year older then the son we can call the son x and the dad x+20. Now five years ago the father was 3 times older then the so we construct the following equation:

x+20−5=3(x−5)

x+15=3x-15

x=15

So now we know that the sons age is 15 meanimg that since the dads 20 years older then him, his age is 20+15 which is 35!

Answers

Answer:

[tex]Each =\pounds 1121[/tex]

Step-by-step explanation:

See comment for complete question.

Given

[tex]Total = \pounds 8968[/tex]

[tex]Projects = 8[/tex]

Required

Determine the amount allotted to each

From the question, we understand that each project gets each allocation.

So, the amount of each is:

[tex]Each =\frac{Total}{Projects}[/tex]

[tex]Each =\frac{\pounds 8968}{8}[/tex]

[tex]Each =\pounds 1121[/tex]

Each project gets £1121

An angle measures 56° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

62,118

Step-by-step explanation:

Let one angle = x

So, other angle = x +56

x +x +56 = 180       {Combine like terms}

2x  + 5 6 = 180      {Subtract 56 form both sides}

        2x = 180 - 56

        2x = 124     {Divide both sides by 2}

        x   = 124/2

        x = 62

Other angle = 62 + 56  = 118

- 3(x - 7) + 2 = 20 I need help to solve it​

Answers

the answer is
X=1

-3(x-7)+2=20
-3x + 21 + 2 = 20
-3x + 23 = 20
-23. -23
-3x=-3
Divide by -3
X=1

Answer:

x=1

Step-by-step explanation:

First you will distribute it

U basically multiply the 3 by the X and the 7 here

-3 x (x = -3x And the 7 becomes a 21

Then you add the 2

21 + 2 = 23

Then you add the -3

-3x + 23 =20

Then using the equation above you subtract 23 from both sides

(-3 + 23) - 23 = 20 - 23

Then you simplify it

-3x = -3

Then you divide them using the same term

  -3

÷ -3

Then you simplfy it and you get

x=1

Which equation has imaginary roots?
A. x(5 + x) = 8
B. x(5 - x) = -3
C. x(x + 6) = -10
D.(2x + 1)(x – 3) = 7

Answers

im not sure but it could possibly be A because x(5+x)=8 would come out to xx=3 which could mean that each x is equal to 1.5.

B comes out to xx=2 which could be x=1.

C comes out to xx=-16 which could mean that x equals -8.

D simplified is 3x-2=7 and comes out to 3x=9 which means x could equal 3.

For each fraction, select the most appropriate estimate. 36 40 choose.. 1 3 choose.. 70 100 choose.. 1 8 choose.. Options: Closest to 0 Closest to one half Closest to 1

Answers

Answer:

Convert each fraction to its percentage form:

= 36 / 40

= 90%

= 1/3

= 33.3%

= 70/100

= 70%

= 1 / 8

= 12.5%

Looking at the percentages:

= 36 / 40 is closest to 1.

= 1/3 and 70/100 are closest to one half which is 50%

= 1/8 is closest to 0.
