Find the values of x and y

Answer:

x= -2 and y= -1

Step-by-step explanation:

1) 4x+3y= -5

2(-2x+2y=6)

(Multipy by 2 )

Becomes

2) 4x+3y= -5

-4x+4y=12

3) -5+12 =7

7y/7=7/7=

y=1

4x+3y=-5

4x+3(1)= -5(plug in Y for 1)

4x+3= -5

4x+3+-3= -5+ -3 (add neigitve 3 on both sides)

4x= -8

4x/4=-8/4( divide 4 on both sides)

x= -2

Answer:

36

Step-by-step explanation:

24 / 3 = 8. 8 x 3 = 36 words

Answer:

36

Step-by-step explanation:

if 24 is 2/3, 24/2=12

12×3=36

do this step by step.

16 X 1.75

- since there is 75% more.

= 28 songs --> in total.

28 X 0.25

-- since 75% are removed.

= 7

final answer: 7 songs.

Answer:

y2=3

Step-by-step explanation:

4y2+7=19

Subtract 7 from both sides.

4y  2 =19−7

Subtract 7 from 19 to get 12.

4y2=12

Divide both sides by 4.

y2= 12/4

Divide 12 by 4 to get 3.

y2=3

​  

Answer:

4y2 + 7 = 19

Step-by-step explanation:

4y2 =19-7

4y2=12

4yx2=12

8y=12

Step-by-step explanation:

The patient weighed lose is : 24.5 pounds.

We have the following information available from the question is:

The weighed of patient is on a low sodium fat diet three months ago is :

[tex]220\frac{1}{8}[/tex]

and, Now the weighed of the patient is : [tex]195\frac{5}{8}[/tex]

We have to find the how many pounds did the patient lose?

Now, According to the question:

The patient weighed lose is:

Three months ago weighed - Current weighed

[tex]220\frac{1}{8}-195\frac{5}{8}[/tex]

=>(1761 - 1565) /8

=> 196 /8

=> 24.5 pounds

Answer:

For simple interest: $50, for compound interest: $56.25

Step-by-step explanation:

For simple interest: 25% *100 = $25

$25*2 = $50

For compound interest:

Year 1) 100+100(.25) = 125

Year 2) 125+125(.25) = 125+31.25 = $156.25

156.25 - 100 = $56.25

Answer:

Year 1) 100+100(.25) = 125

Year 2) 125+125(.25) = 125+31.25 = $156.25

156.25 - 100 = $56.25

Answer: Yes, Brad has enough oranges.

Step-by-step explanation:

Given :

The orange required for one bowl = 12 oz

Thus orange required for 12 bowls = [tex]\frac{12}{1}\times 12=144oz[/tex]

Oranges available with Brad for 12 bowls = 10 lb = [tex]10\times 16=160oz[/tex]

(1lb=16oz)

As organges required is less than oranges available with Brad, thus Brad has enough oranges.

Answer:

Area of the triangle = 60 cm²

Step-by-step explanation:

Two equal sides of the given isosceles triangle measure 13 cm.

Third side of the triangle = 10 cm

Since, formula to get the area of a triangle with given three sides is given by,

Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Where a, b and c represent the sides of the triangle

And s = [tex]\frac{a+b+c}{2}[/tex]

For the given isosceles triangle,

s = [tex]\frac{13+10+13}{2}[/tex]

s = 18

(s - a) = (18 - 13) = 5 cm

(s - b) = (18 - 10) = 8 cm

(s - c) = (18 - 13) = 5 cm

Substituting these values in the formula,

Area of the triangle = [tex]\sqrt{18\times 5\times 8\times 5}[/tex]

                                 = [tex]\sqrt{3600}[/tex]

                                 = 60 cm²

Therefore, area of the given isosceles triangle is 60 square cm.

Answer:

x = 1, y = 2

Step-by-step explanation:

Multiply 2x - 8y = -14 ​by 5 to get 10x - 40y = -70

Subtract (10x - 40y = -70) - (10x - 9y = -8)

Solve -31y = -62 for y

y = 2

Plug in y value to get x value

x = 1

Answer:

the second answer choice

Step-by-step explanation:

Answer:

Where's the x?

I am assuming that the problem must be

-3 + 42 > 3x

if that is true, then

x < 13.

As this statement is, -3 + 42 > 3 is a true statement because -3 + 42 = 39, and

39 > 3 [39 is always greater than 3]

Step-by-step explanation:

Let me know if you need a step by step.

Answer:

D) x < -15

Step-by-step explanation:

-3x - 42 >3

Add 42 to each side

-3x - 42+42 >3+42

-3x > 45

Divide each side by -3.  Remember to flip the inequality since we are dividing by a negative

-3x/-3 < 45/-3

x < -15
