Answer:

you know its wrong because when you divide, the number gets smaller

Answer:

10

Step-by-step explanation:

2x - 3y = 24 ------ (1)

3x + 4y = 2 ------ (2)

(1) × 4,

8x - 12y = 96 ------ (3)

(2) × 3,

9x + 12y = 6 ------ (4)

(3) + (4)

17x = 96 + 6

= 102

x = 102 ÷ 17

= 6

Sub x = 6 into (2),

3(6) + 4y = 2

18 + 4y = 2

4y = 2 - 18

= -16

y = -16 ÷ 4

= -4

Therefore,

x - y = 6 - (-4)

= 6 + 4

= 10

i hope this helps you !!

Answer:

3/16

Step-by-step explanation:

If an article takes half of the page then;

1article = 1/2 of a page

3/8 of the article = x

Cross multiply

1×x = 1/2×3/8

x = 3/(2×8)

X = 3/16

Hence the photo takes 3/16 of the magazine

Answer:

a)8

b)13

Step-by-step explanation:

a) ar = c

a^2+b^2=c^2

4^2+7^2=c^2

16+49 = c2

c = [tex]\sqrt{65}[/tex] ~8

b) sa= c

a2+b2=c2

7^2 + (15-4)^2

49+121 = c2

c= [tex]\sqrt{170}[/tex] = 13

I hope im right!!

Answer:

(25+16)-(13*2)=31

2.06 is your answer ☺️

Answer:

Step-by-step explanation:

Yes it's a function.

You may be looking at v which produces m

You may be looking at r which also produces m.

That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).

If you have a member of the domain producing 2 y values,  that doesn't work. That would not be a function.

This example is a function.

The measure of angle 6 in the transversal that cut the parallel lines is 57 degrees

When a transversal line cut parallel lines, the angles formed are corresponding angles, alternate angles, vertically opposite angles etc.

Therefore,

∠2 = 180  - 123 = 57° (angle on a straight line)

Therefore,

∠2 ≅ ∠6 (corresponding angles)

Hence,

∠6 = 57 degrees

Hi there!

[tex]\large\boxed{x = 11}[/tex]

From the diagram, we can see that ΔAEF, and ΔACB are similar, isosceles triangles.

Therefore:

∠B and ∠F are congruent because they are corresponding angles, and ∠B and ∠E are congruent because of equal base angles in an isosceles triangle.

Therefore:

7x - 11 = 6x

Subtract 6x from both sides:

x - 11 = 0

Add 11 to both sides:

x = 11.

Answer:

x > 5

Step-by-step explanation:

Answer:

x = 17.32

y = 10

Step-by-step explanation:

USsing the SOH CAH TOA identity

sin theta = opp/hyp

sin 30 = y/20

y = 20sin30

y = 20(0.5)

y = 10

Using Pythagoras theorem to get the value of x

20^2 = x^2 + y^2

400 = x^2 + 10^2

400 - 100 = x^2

300 =x^2

x = √300

x = 17.32
