what is the value of x , if y = 2
in the given equation ;

5x + 2y = 9​

Answers

Answer 1

Answer:

Solve the system of equations.

x = 1

y = 2

Step-by-step explanation:

Hope it is helpful....

Answer 2
ExplanationGiven the equation.

[tex]5x + 2y = 9[/tex]

with given condition where y = 2.

Therefore, substitute the value of y in the equation.

[tex]5x + 2(2) = 9 \\ 5x + 4 = 9[/tex]

Solve the equation for x-term.

[tex]5x = 9 - 4 \\ 5x = 5 \\ x = \frac{5}{5} \longrightarrow \frac{1}{1} \\ x = 1[/tex]

Check the answer by substituting both x-value and given y-value in the equation.

[tex]5x + 2y = 9 \\ 5(1) + 2(2) = 9 \\ 5 + 4 = 9 \\ 9 = 9 \longrightarrow \bf{true} \: \green{ \checkmark}[/tex]

Hence, the value of x is 1.

Answer

[tex] \large{x = 1}[/tex]

If 1 is subtracted from a number and this difference is tripled the result is 23 more than the number

Answers

Answer:

The number is 13

Step-by-step explanation:

Let the number be y

1 is subtracted from the number. This can be written as:

y – 1

The difference is tripled. This can be written as:

3(y – 1)

The result of the difference tripled is 23 more than the number. This can be written as:

3(y – 1) = 23 + y

Thus, we can obtain the value of y as follow:

3(y – 1) = 23 + y

Clear bracket

3y – 3 = 23 + y

Collect like terms

3y – y = 23 + 3

2y = 26

Divide both side by 2

y = 26 / 2

y = 13

Thus, the number is 13.

Answer:

x = 5.5

Step-by-step explanation:

PM = MR

4x - 12 = -2x + 21         {add 2x to both the sides}

4x - 12 + 2x = -2x + 2x + 21

6x - 12 = 21         {Add 12 to both sides}

6x - 12 + 12 = 21 + 12

            6x  = 33

              x = 33/6

x = 5.5

Step-by-step explanation:

here,

4x-12 = -2x+21 4x+2x = 21+12 6x = 33 x = 33/6

The correct answer would be C. This is because when you have a fraction that has variables with exponents, you can just subtract the exponents in the numerator from the denominator exponents. So, 4-2 is 2. Then you bring that down to the denominator and get the correct answer.

There are 9 flash cards with numbers from 20 to 28 written on them. Laura drew the card with 22 on it. She is about to draw another card. What is the probability that the sum of the numbers on these two cards will be a multiple of 5?

Answers

Answer:

1 /4

Step-by-step explanation:

Multiples of 5 = (5, 10, 15, 20, 25, 30, 35, 40, 45)

Numbers on card : (20,21,22,23,24,25,26,27,28)

Number on first card = 22

To have a sum which is a multiple of 5 ; number on second card must be either :

23 or 28

22 + 23 = 45

22 + 28 = 50

Since only 2 of the cards will. Result in a sum which is a multiple of 5

Required outcome = 2

A police officer gets paid $50 per hour. If she works a holiday, she gets paid time and a half. How much would the officer earn if she worked 7 hours on Christmas day (a holiday)?

a.) $500.00

b.) $525.00

c.) $350.00

Answers

Answer:

the correct answer is b $525.00

Step-by-step explanation:

half of her earnings is 25 dollars if she makes time and a half it would be 50 + 25 = $75/hr of overtime (overtime wage)

if she works 7 hours of overtime then...  (hours she work) x (overtime wage)

7 x 75 = 525

so her pay would be $525.00

the correct answer would be B

First, you need to convert the mixed numbers into improper fractions. Then, you make sure the denominators are the same. (For example, in the first problem, you have to change the 3/4 to 6/8 to match the 17/8.) Then, you subtract the two fractions, and then turn the resulting improper fraction to a mixed number!

Step-by-step explanation:

Suppose Joe earned three times as much as Marty during the summer. Together they earned $210. How much did each earn?

(write a system of equations)

Answers

Let’s say Joe earned = x, and Marty earned y

Together they earned $210
So, x + y = $210

If Joe earned 3 times as much as Marty then:
x = 3y

Thus we can substitute and say,
3y + y = 210
4y = 210
y = 52.5

x = 3y = 3(52.5)
x = 157.5

Joe earned $157.5 and Marty earned $52.5
