Answer:

54

Step-by-step explanation:

120 x .45 = 54; and to check

54 ÷ 120 = 0.45

First you move the decimal point to the right 2 spaces to change the percent (%) to a decimal (change 45% to .45); and then you multiply by the 120. So it turns into

.45 x 120 = 54 the answer is: 54

To check you go in the opposite direction.  Move the decimal point to the right ( 45 x 120 ) and the answer is 5400; which is a whole number, which means the decimal is invisibly at the end; then move the decimal point back two spaces to the left and it now looks like this 54.00; which is a whole number and the two zeros at the end can be taken off; there's that invisible decimal that makes it a whole number that you p.s. don't ever need...  You are right back to 54 :)

Hope that helps! <3

Answer:

2 percent increase

Step-by-step explanation:

Let x be the first number

It increases by 70 %

The new number is

m = x+ .70x

   = 1.7x

Let y be the second number

It decreases by 40 %

The new number is

n =y - .40 y

  = .6y


The product of the original numbers is xy

The product of the new number is

mn = (1.7x * .6y) = 1.02xy

The new number is larger than the old number so it is an increase.

Percent increase is  new - original divided by original  times 100%

Percent increase = (1.02 xy - xy)

                                -----------------  * 100%

                                 xy  

                           = .02 xy

                                ------- * 100 %

                                 xy  

                            = .02 * 100 %

                             = 2%

1 - Qual a solução da equação 3x – 4 = 14? * 1 ponto a) 10 b) 7 c) 6 d) 15 2 - A idade de um pai é igual ao triplo da idade do f
topjm [15]

Responda:

1.) 6;

2.) d) O pai tem 36 anos e o filho tem 12 anos.

Explicação passo a passo:

1.)

Dada a equação: 3x - 4 = 14

3x = 14 + 4

3x = 18

Divida os dois lados por 3

x = 6

2) Dado que ;

Idade do pai = 3 vezes a idade do filho

Idade do pai + idade do filho = 48

Deixe a idade do pai = f; idade da criança = c

Matematicamente ;

f = 3c - - - (1)

f + c = 48 - - - - (2)

Substitua f = 3c em (2)

3c + c = 48

4c = 48

c = 48/4

c = 12

Substitua c = 12 em (2)

f + 12 = 48

f = 48 - 12

f = 36

Portanto ;

Idade do pai = 36 Idade da criança = 12
