Answer:

[tex]\huge\boxed{\sf x = -2}[/tex]

Step-by-step explanation:

4x - 2y = 5 -------------------------------(1)

y = 3x - 1 ----------------------------------(2)

Put Eq. (2) in (1)

4x - 2(3x-1) = 5

4x - 6x + 1 = 5

-2x + 1 = 5

Subtracting 1 to both sides

-2x = 5 - 1

-2x = 4

Dividing both sides by -2

x = 4 / -2

x = -2

Answer: slope =1/2  y intercept (0,6)

Step-by-step explanation: use the slope and y intercept form y=mx + b

The required equation is m = 42 - 6.50d which is the correct answer would be an option (C).

A linear equation is defined as an equation in which the highest power of the variable is always one.

We have been given that Reese had $42 in his pocket on Sunday night. He spent $6.50 every day for lunch.

Let d represents the number of days since Sunday, and m represents the amount of money remaining

Reese has 42 total and it subtracts by 6.50$ every day

According to the given question,

The linear equation would be as

m = 42 - 6.50d

The above model equation is the relationship between d, the number of days since Sunday, and m, the amount of money remaining

Therefore, the required equation is m = 42 - 6.50d.

I just it into a calculator and got 162.72. Hope this helps you! Have a nice day and a nice rest of the holidays!

The product of 4.52 times by 36 is 162.72

Given,

4.52 times by 36

We need to find the product.

Example:

2.3 x 3.4 = 7.82

There are two numbers after the decimal point.

In 2.3 there is one number after the decimal point.

In 3.4 there is one number after the decimal point.

Now,

1 + 1 = 2 numbers

7.82 has two numbers after the decimal point.

We have,

4.52 times by 36

4.52 x 36 = 162.72

4.52 x 6 = 27.12

4.52 x 3 = 13.56

         4.52

       x   36

        27.12

     13.56        

     162.72

4.52 has two numbers after the decimal point.

162.72 has two numbers after the decimal point.

Thus the product of 4.52 times by 36 is 162.72

Answer:

x=4

Step-by-step explanation:

Hope this helps!

Plz, mark brainiest! ^.^

Answer:

x = 4

Step-by-step explanation:

Use the distributive property to distribute the -3 amongst the 2x and the -3 in the parenthesis. Once distributed you should have -6x + 9 = -5x + 5. Next, you want to get all like terms on the same side, and to do that you must swap the +9 and the -5x. When you swap these, you must 'flip' the sign and change 9 to -9 and -5x to 5x. Now the equation should look like this: -6x + 5x = -9 + 5.

Now just solve. After solving, it should look like this: -1x = -4. Now to get rid of the negatives. Just divide each side by negative one and your answer is x = 4.

Answer:

Yes it is.

Step-by-step explanation:

Best way is to use percentages you know when estimating.

We know 50% is half.

50% of 242 is 121.

So it has to be more than 121.

10% of 242 is 24.2  so add that to 121 and you get 145.2

You are 60% so far. You just need 9% more.

Add another 10% which is 24.2 and you get 169.4, which is over but we used 10% instead of 9% so the estimate is reasonable and close.

Answer and explanation:

We are told that Sarah has 600g of butter, 300g of caster sugar, 1kg of plain flour, and 500g of cornflour

We are also told that she found this list of ingredients for making 8 shortbread biscuits. The question isn't clear on whether the ingredients listed above are for the 8 shortbreads, or ingredients for 8 shortbreads were omitted.

We are told Sarah wishes to make as many shortbreads as possible.

To work out how many shortbreads Sarah can make, we need to know the ingredients required for one shortbread(or a number of shortbreads) and ingredients Sarah currently has. The question lists Sarah's ingredients and the number of shortbreads(8) that can be made with them, but doesn't go further than this. Therefore we can conclude that Sarah can only make 8 shortbreads given the amount of ingredients in her possession.

Step-by-step explanation:

the three binomial factors are (x+2)(x-1)(x-3)

Answer:

C

Step-by-step explanation:

Given a zero x = a then the corresponding factor is (x - a )

Here the zeros ( where the graph crosses the x- axis ) are at

x = - 2, x = 1 and x = 3

Thus the corresponding binomial factors are

(x - (- 2) ), (x - 1) and (x - 3), that is

(x + 2), (x - 1), (x - 3) → C

Answer:

The smallest composite number for [tex]n[/tex] is 24, which is the product 2 and 12.

Step-by-step explanation:

A composite number is an integer that is not a prime number, that is, a number that can be divided only by one and itself. Let be [tex]n[/tex] the smallest composite number such that there are two positive integers [tex]x[/tex], [tex]y[/tex] such that [tex]x - y = 10[/tex] and [tex]x\cdot y = n[/tex]. [tex]n[/tex] is a positive integer, since both integers are positive. Then, we can use the following formula:

[tex](y+10)\cdot y = n[/tex]

[tex]y^{2}+10\cdot y = n[/tex]

[tex]y^{2}+10\cdot y - n = 0[/tex] (1)

We obtain the roots of this second order polynomial by means of the Quadratic Formula:

[tex]y = \frac{-10\pm \sqrt{10^{2}-4\cdot (1)\cdot (-n)}}{2}[/tex]

[tex]y = -5\pm \sqrt{25+n}[/tex] (2)

Given that [tex]y > 0[/tex], we must observe the following inequation:

[tex]-5\pm \sqrt{25+n}>0[/tex] (3)

[tex]\sqrt{25+n} > 5[/tex]

[tex]25 + n > 25[/tex]

[tex]n > 0[/tex]

Let is find the values of x and y by iterative means:

x = 11, y = 1

[tex](11)\cdot (1) = 11[/tex]

11 is not a composite number, but a prime number.

x = 12, y = 2

[tex](12)\cdot (2) = 24[/tex]

24 is a composite number, which contains the following product of prime numbers:

[tex]2^{3}\cdot 3 = 24[/tex]

The smallest composite number for [tex]n[/tex] is 24, which is the product 2 and 12.

Answer: 3 minutes and 12 seconds

Step-by-step explanation: You can see 8 minutes every 10 days as a fraction (8/10). This can be simplified to 4/5, meaning that the amount of time gained will be 4/5 of the # of days that have passed. 4/5 of 4 days is 3.2 minutes, and that can be converted to 3 1/5. 60 seconds divided by 5 is 12 seconds, meaning that 1/5 of a minute is 12 seconds. Therefore, the answer is 3 minutes and 12 seconds.

Answer:

15. [tex] x = 8 [/tex]

16. m<V = 103°

17. [tex] x = 14 [/tex]

Step-by-step explanation:

15. The figure given is quadrilateral. Sum of interior angles of a quadrilateral = 360°

Therefore:

[tex] (10x + 6) + (13x - 2) + (8x - 1) + (180 - 71) = 360 [/tex]

Solve for x

[tex] 10x + 6 + 13x - 2 + 8x - 1 + 109 = 360 [/tex]

Add like terms

[tex] 31x + 112 = 360 [/tex]

Subtract 112 from each side

[tex] 31x = 248 [/tex]

Divide both sides by 31

[tex] x = 8 [/tex]

16. The polygon is a hexagon. Sum of interior angles of a hexagon = 720. Therefore:

[tex] 90 + (7x + 3) + 128 + (5x + 8) + 111 + (9x - 19) = 720 [/tex]

Solve for x

[tex] 90 + 7x + 3 + 128 + 5x + 8 + 111 + 9x - 19 = 720 [/tex]

Add like terms

[tex] 321 + 21x = 720 [/tex]

Subtract 321 from each side

[tex] 21x = 399 [/tex]

Divide both sides by 21

[tex] x = 19 [/tex]

m<V = 5x + 8

Plug in the value of x

m<V = 5(19) + 8 = 95 + 8

m<V = 103

17. The polygon is a regular pentagon. This means each of the angles measures 108°. The sum of the interior angles all together is 540.

Therefore:

[tex] (9x - 18) = 108 [/tex]

Solve for x

[tex] 9x - 18 = 108 [/tex]

Add 18 to both sides

[tex] 9x = 126 [/tex]

Divide both sides by 9

[tex] x = 14 [/tex]

Answer:

(x,y)=(-4/5,10/19)

Step-by-step explanation:

x+2y=3

x-8y=-16

x+2y=3

-x+8y=16 (multiply both sides by-1)

10y=16

y=16/10

x+2(16/10)=3

x=-4/5
