Answer:

X=-1

Y=1

Solve using Elimination.

Step-by-step explanation:

Multiply the second equation by 7.

The two equations are now:

7x+6y=-1

-7x +14y=21

Combine the two equations

7x and -7x cancel each other out, 14y+6y is 20y, and 21 - 1 is 20.

The equation is now

20y=20, divide 20 on both sides to get Y=1.

Now, substitute 1 as Y in the second equation for -x+2(1)=3

-x+2=3, can be simplified, by subtracting 2 from both sides. Giving us

-x=1.

Divide both sides by -1 for X=-1

Final answers being X=-1, Y=1

Answer:

A

Step-by-step explanation:

22 successes out of a group of 40 means 22/40 were good. Now, simplify 22/40. Both can be divided by 2.

22/2 = 11

40/2 = 20

Now you have 11/20. Put this in decimal form and you have 0.55

Option A answer is 0.55

The proportion of a sample is the ratio of the number of successes or defeats to the total size of the sample, it is used for understanding which trend is more followed and also has many uses in the real world.

The size of the sample is 40.

There are 22 successes in the sample.

To find the proportion of success we have to find the ratio of 22 and 40 which is 11:20, and in numerical terms 0.55

Hence option A is correct, the proportion is 0.55

Answer:

The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5

Step-by-step explanation:

Let

x ------> the number of pounds of apples

(x-2) -----> the number of pounds of grapes

we know that

Solve for x

so

therefore

The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5

Answer:

4.5 pounds of apples

2.5 pounds of grapes

Step-by-step explanation:

a = # of apples

(a - 2) = # of grapes

1.68a + 2.48(a - 2) = 13.76

1.68a + 2.48a - 4.96 = 13.76

4.16a = 18.72

a = 4.5; Apples

(a - 2) = 2.5;  Grapes

Answer:

[tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

"The sum of 8 times a number (x) and 7 equals 3."

Let, "a number" = x

8x + 7 = 3

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

First, subtract 7 from both sides of the equation:

8x + 7 (-7) = 3 (-7)

8x = 3 - 7

8x = -4

Next, divide 8 from both sides of the equation:

(8x)/8 = (-4)/8

x = -4/8

x = -1/2

-1/2 is your number, or -0.5

Answer:

Nickel = 13

Dimes = 8

Quarters = 16

Step-by-step explanation:

Let N denote Nickel,

Let D denote dime

Let Q denote quarter

Now, from online conversions;

1 nickel = 5 cents

Also, 1 dime = 10 cents

Also, 1 quarter = 25 cents

Isabelle has $5.45 which is also 545 cents.

Thus, we have;

5N + 10D + 25Q = 545 - - - (eq 1)

We are told that;

she has five more nickels than dimes, and twice as many quarters than dimes.

Thus;

N = D + 5

Also, Q = 2D

Plugging them for N and Q in eq 1 givens;

5(D +5) + 10D + 25(2D) = 545

5D + 25 + 10D + 50D = 545

25 + 65D = 545

65D = 545 - 25

65D = 520

D = 520/65

D = 8

Thus; N = D + 5 = 8 + 5 = 13

Q = 2D = 2 × 8 = 16

Answer:

A

Step-by-step explanation:

Given :

2x + 4y = 14  ---------- eq 1

4x + y = 20 ---------- eq 2

if you multiply eq 2 by -4 on both sides, you get

-4 (4x + y = 20) = -4 (20)

-16x -4y = -80 --------- eq3

we can see that eq. 1 and eq 2 together forms the system of equations presented in option A, Hence A is equvalent to the orginal system of equations given in the question.

The system of equations which is equivalent to the [tex]2x + 4y = 14[/tex],[tex]4x + y = 20[/tex]  is given in option [tex](A)[/tex] i.e. [tex]2x + 4y = 14[/tex] and [tex]-16x - 4y = -80[/tex].

System of equations comprises of two or more equations and seeks common solutions to the equations.

We have,

[tex]2x + 4y = 14[/tex]   [tex]........(i)[/tex]

  [tex]4x + y = 20[/tex]    [tex]........(ii)[/tex]

Now,

To check that which option suits best for system of equation,

Lets multiply equation [tex](ii)[/tex] by [tex](-4)[/tex],

  [tex](-4) (4x + y) = (-4)*(20)[/tex]

[tex]-16x-4y=-80[/tex],

So, this above obtained equation is in option  [tex](A)[/tex].

Hence, we can say that the system of equations which is equivalent to the [tex]2x + 4y = 14[/tex] ,[tex]4x + y = 20[/tex] is given in option [tex](A)[/tex] i.e. [tex]2x + 4y = 14[/tex] and [tex]-16x - 4y = -80[/tex].

(1,-3)

Step-by-step explanation:

5x+4y=-7

-5x-2y=1

Cancel +5x - 5

     2y=-6

      y=-3

5x-12=-7   or    -5x+6=1

5x=5                -5x=-5

x=1                     x=1

Answer:

y = -3, x = 1

or

(1, -3)

Step-by-step explanation:

5x + 4y = -7

-5x - 2y = 1

add the two equations together

0x + 2y = -6

2y = -6

2y/2 = -6/2

y = -6/2

y = -3

now substitute y = -3 into either of the equations

5x + 4y = -7

5x + 4(-3) = -7

5x - 12 = -7

5x = -7 + 12

5x = 5
