Answer:

0.08

Step-by-step explanation:

1.7 – 2.7 – 1.34 + 4.9 – 1.48

 2.7

- 1.7       (subtract 1.7 from 2.7)

--------

-1.0      [2.7 is greater than 1.7 and 2.7 is negative(in the ques) , therefore  1.0 is negative]

-1.0-1.34

we know that  (-) (-) is (+)

therefore add -1.34 with -1.0

   1.34

+  1.0

-----------

  -2.34 [since 1.34 is greater and it is negative]

-2.34+4.9

we know that (-)(+) is (-)

therefore subtract -2.34 from 4.9

  4.90  ← (we put zero so that we can subtract without getting confused)

-  2.34

------------

  1.56 [1.56 is positive because 4.9 is greater and it is positive]

1.56-1.48

here, digit before the decimal point is same but  after decimal point .56 is greater than .48  therefore subtract 1.48 from 1.56

  1.56

-  1.48

-----------

  0.08

therefore,  1.7 – 2.7 – 1.34 + 4.9 – 1.48 = 0.08

hope it helps you!

Answer:

Step-by-step explanation:

y = k x X

7 = k x 2

7/2 = k...............1

hence y = 7/2x (substituting eq 1)

y = 21

therefore, x = 2y/7

x = 2 x 21

         7

x = 2 x 3

x = 6    

The required value of x is 6, when y =21 and y directly varies as x.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio.

Given that,

y directly varies as x,

Implies that,

y ∝ x

or y = k x         (1)

When x = 2 and y = 7, from equation (1)

7 = k × 2

k = 7 / 2

To find the value of x when y = 21,

Substitute values of k = 7 /2 and y = 21 in equation (1),

21 = (7 / 2) × x

3 × 2 = x

x = 6

The value of x when y = 21, is 6.

Answer:

x=20/3 y=17/3

Step-by-step explanation:

1. x-y=1

2. 2x+y=19

The first equation can be rewritten as 2x-2y=2

We can then subtract the second equation from this:

2x-2y=2

2x+y=19

-3y=-17

y=17/3

Plug this into to solve for x:

x-17/3=1

x=17/3+1

x=20/3

Answer:

the answer is 91

Step-by-step explanation:

One group of 9 quarters, 3 dimes, and 1 nickel has the value of $9 \times 25 + 3 times 10 + 5=26 cents or 2.60 in total.

Since the coins she has are in this same ratio 9:3:1, we can split her coins up into groups of 9 quarters, 3 dimes, and 1 nickel, with each group having a value of 2.60

Because the total value of her coins is 18.20and 18.20\2.60=7, she has 7 of these groups of coins.

Each of these group contains 13 coins, so she has 7 times 13 = 91 coins in total.

Each of these group contains 13 coins, so she has total 91 coins.

A dollar is further divided into some majorly used parts as:

A cent = 100th part of a dollar = $1/100 = $0.01

A nickle= 20th part of a dollar = $1/20 = $0.05

A dime = 10th part of a dollar = $1/10 = $0.10

A quarter = 4th part of a dollar = $1/4 = $0.25

One group of nine quarters, 3 dimes, and 1 nickel has the value of $9

25 + 3 times 10 + 5=26 cents or 2.60 in total.

Since the coins Nathalie has are in this same ratio 9:3:1, thus we can split her coins up into groups of 9 quarters, 3 dimes, and 1 nickel, with each group having a value of 2.60

Due to the total value of her coins is 18.20

18.20/2.60=7,

Hence, she has 7 of these groups of coins.

Each of these group contains 13 coins, so she has total ;

7 x 13 = 91 coins

Answer:

x = 4, x ≠ -1

Step-by-step explanation:

√3x + 4 = x

(√3x + 4)² = x² (Square both sides to get rid of the radical.)

3x + 4 = x²

0 = x² - 3x - 4 (Set everything to 0 by moving everything to one side.)

0 = (x - 4)(x + 1) (Factor.)

x = 4   x = -1

Now we need to check for extraneous solutions:

√3(4) + 4 = 4

√12 + 4 = 4

√16 = 4

4 = 4

√3(-1) + 4 = -1

√-3 +4 = -1

√1 = -1

1 ≠ -1

-1 is an extraneous solution.

Answer:

x=3

Step-by-step explanation:

14x= 5(2x-4) - 12

14x= 10x - 20 - 12

14x= 10x -8

24x= 8

x= 3

Answer:

x = 7 1/3

Step-by-step explanation:

First, add 1/2 and 6

1/2 + 12/2 = 13/2 = 6 1/2

Our equation now:

13/2 over 3 - x - 3 over 2 = 0

Next, divide 13/2 by 3

13/2 divided by 3 = 13/6

Our equation now:

13/6 over 3 - (x - 3) over 2 = 0

Now, find common denominators and simplify

13/6 - ((x - 3) times 3) over 6 = 0

22 - 3x over 6 = 0

Multiply by six on both sides

22 - 3x = 0

Subtract 22 from both sides

-3x = -22

Divide by -1

3x = 22

Divide both sides of the equation by 3

x = 22/3

x = 7 1/3
