Answer:

X=3, y=-6

Step-by-step explanation:

7x+4y=-3 equation 1

-7x-5y=9 equation 2

     -y=6. Add above two equations    

      Y=-6

solve for x by inputting y value into either equation.

7x+4(-6)=-3

7x-24=-3

7x=21

x=3

check answer by inputting x and y values into either equation

-7x-5y=9

-7(3)-5(-6)=9

–21+30=9

9=9

Answer:

Volume: 1080

Surface Area: 684

Answer: 38°

Step-by-step explanation:

∠1 and m∠62° are congruent as this is an isosceles triangle.

∠1 = 62°

∠2 + ∠1 + m∠62° = 180° because they form a triangle

∠2 + 62 + 62 = 180

∠2 + 124 = 180

Subtract both sides by 124

∠2 = 56°

∠2 and ∠3 are linear pairs so they're supplementary.

∠3 + ∠2 = 180°

∠3 + 56 = 180

Subtract both sides by 54

∠3 = 124°

∠4 + m∠18° + ∠3 = 180° because they form a triangle

∠4 + 18 + 124 = 180

∠4 + 142 = 180

Subtract both sides by 142

∠4 = 38°

Answer:

15 feet

Step-by-step explanation:

The ladder is the hypotenuse of a right triangle, with the legs being 9 ft and 12 ft long (see the picture).

To solve for the length of the ladder, use the Pythagorean Theorem.

[tex]9^{2} +12^{2} =c^{2} \\c=\sqrt{9^{2} +12^{2}} \\c=\sqrt{81+144} \\c=\sqrt{225} \\c=15[/tex]

Answer:

x = 16

I hope this helps!

Answer:

x=16

Step-by-step explanation:

The angles of the inside of a triangle always add up to 180

2*16= 32

3*16=48

16+84=100

32+48+100=180

Answer:

Side a is that side opposite to the hyp and b is the short side and c is the hyp

So a/b is 24/x

we need b

We find b=10

so 24/10 and we simply to 12/5

Answer:

Teo is 8 years old and Richard is 29 years old

Step-by-step explanation:

Let us solve the question

Assume that Teo is x years old

∵ Teo is x years old

∵ Richard is 13 years older than twice Teo's age

→ It means multiply x by 2, then add 13 to get the age of Richard

∴ Richard's age = 2x + 13

∵ Richard and Teo have a combined age of 37 years

→ Add their ages and equate the sum by 37

∴ x + 2x + 13 = 37

→ Add the like terms

∵ (x + 2x) + 13 = 37

∴ 3x + 13 = 37

→ Subtract 13 from both sides

∵ 3x + 13 - 13 = 37 - 13

∴ 3x = 24

→ Divide both sides by 3 to find x

∴ x = 8

∵ x represents Teo's age

∴ Teo is 8 years old

→ Substitute the value of x in the expression of Richard age to find his age

∵ Richard age = 2(8) + 13 = 16 + 13 = 29

∴ Richard is 29 years old

∴ Teo is 8 years old and Richard is 29 years old

Answer:

chile I think it's A

Step-by-step explanation:

anyway, if it goes through the same point as the the first one, it becomes a solution and depending on the equation everything either to the left or right, above or below, becomes a solution as well. don't stress bruv, we all got small brain

Given:

The directed line segment from (-2, -5) to (7, 10).

A point partitions the segment into a ratio of 2 to 1.

To find:

The coordinates of that point.

Solution:

Section formula: If a point divides a line segment in m:n, then the coordinates of that point are

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

The point divides the line segment from (-2, -5) to (7, 10) in 2:1.

Using section formula, we get

[tex]Point=\left(\dfrac{2(7)+1(-2)}{2+1},\dfrac{2(10)+1(-5)}{2+1}\right)[/tex]

[tex]Point=\left(\dfrac{14-2}{3},\dfrac{20-5}{3}\right)[/tex]

[tex]Point=\left(\dfrac{12}{3},\dfrac{15}{3}\right)[/tex]

[tex]Point=\left(4,5\right)[/tex]

Therefore, the coordinates of the partition point are (4,5).

Answer:

The answer is 105

Step-by-step explanation:

(60)(350) = k

21000 = k

(m)(200) = 21000

m = 105

Answer:

V = nl^2h or V = nw^2h

Step-by-step explanation:

The computation of the volume of the solid is given below:

Here the volume of the sold would be considered as the volume of 1  prism i.e. rectangular times n

Now as we know that

The volume of a rectangular prism is V is

lwh.

As L = w

Here cross section would become a square

So

V = l^2h

So,

The volume of the resulting solid would be

V = nl^2h or V = nw^2h

Answer:

Yes, because if you divide $2.03 by $.58 you will get 3.5. Once rounded 3.5 turns to 4

Step-by-step explanation:

Answer:

The slope of given line is -5/3

Step-by-step explanation:

Given equation of line is:

5x+3y = 45

In order to find the slope of the given line, we have to convert the equation in slope-intercept form first

So,

[tex]5x+3y = 45\\3y = -5x+45[/tex]

Dividing both sides by 3

[tex]\frac{3y}{3} = \frac{-5}{3}x+\frac{45}{3}\\y = -\frac{5}{3}x+15[/tex]

The slope-intercept form is given by:

[tex]y = mx+b[/tex]

Here m(co-efficient of x) is the slope of line

Comparing both equations, we get

m = -5/3

Hence,

The slope of given line is -5/3

Answer:

x = 8/3

Step-by-step explanation:

3x + 16 = 24

3x = 24 - 16 (subtract 16 from both sides)

3x = 8

x = 8/3 (divide both sides by 3)

Answer:

The midpoint is;

(-1,-0.5)

Step-by-step explanation:

To do this, we shall use the midpoint formula

That would be;

(x,y) = (x1 + x2)/2 , (y1 + y2)/2

(x1,y1) = (-9,-1)

(x2,y2) = (7,0)

(x,y)

= (7-9)/2 , (0-1)/2

= -2/2 , -1/2

= (-1, -0.5)

Answer:

Step-by-step explanation:x<-5/2

Answer:

15 months

Step-by-step explanation:

35x+20=545

Subtract 20 from both side to figure out how many months he paid for....

35x+20-20=545-20

35x=525

Divide 35 on both sides....

x=15

Therefore, he has been a member for 15 months

Check:

35(15)+20=545

525+20=545

545=545

IT'S CORRECT!!!
