Answer:

26/15

Step-by-step explanation:

13/x= 2/2-x

the next step from here is to cross multiply and when we do that it's looks like this

13(2-x)=2*x

then we multiply

26-13x=2x

we then collect like terms

26=15x

therefore x= 26/15

we can leave our answer in this format or convert it to mixed fraction or decimal but its best to leave it in this format

Two or more expressions with an Equal sign is called as Equation. Value of x is 26/15 for equation 13/x=2/(2-x)

Two or more expressions with an Equal sign is called as Equation.

The given equation is

13/x=2/(2-x)

Apply cross multiplication

13(2-x)=2x

Apply Distributive property on LHS side

13(2)-13x=2x

26-13x=2x

Add 13x on both sides

26-13x+13x=2x+13x

26=15x

x=26/15

Hence value of x is 26/15 for equation 13/x=2/(2-x)

Answer:

Step-by-step explanation:

First we need the height of the cone

so we divide the cone to two equal parts that means the adjacent 5 inches will be divided into two to give 2.5

then we use get a triangle from the cone and that's how we find our height using pythagoras theorem

hypotenuse Square = opposite Square + adjacent Square

7^2 = x^2 + 2.5^2

therefore our height is 6.53

now to get the surface area of the cone we use the formula

pi×r( r + Square root of r^2 + h^2

Answer:

x [tex]\geq[/tex]  31

Step-by-step explanation:

Total number of the yearbooks is 56 + x

Total money earned is 23*(56 + x)

so 23*(56 + x) [tex]\geq[/tex] 2001

56 + x [tex]\geq[/tex] 2001/23 = 87

x [tex]\geq[/tex] 87 - 56 = 31

Answer:

a=10

Step-by-step explanation:

use a^2+b^2=c^2

(a+2)^2+(a-5)^2=(a+3)^2

a^2+4a+4+a^2-10a+25=a^2+6a+9

2a^2-6a+29=a^2+6a+9

a^2-12a=-20

a^2-12a+20=0

quadratic formula→(12+/-8)/2

a=10 or 2

2 is not an option because 2-5=-3 which isn't possible in this case.

so a=10

Apply Pythagorean theorem

There is a side a-5 so 2 is not a answer

Answer:

[tex]f(x)=x(x-7)(x+8)^2[/tex]

Step-by-step explanation:

The zeros of the polynomial are all the values of [tex]x[/tex] for which the function [tex]f(x)=0[/tex]

Therefore,

[tex]x = 0[/tex]

[tex]x = -8 \implies x + 8 = 0[/tex] (twice)

[tex]x = 7 \implies x -7 = 0[/tex]

Write the polynomial as a product of its factors:

[tex]f(x)=x(x-7)(x+8)^2[/tex]

keeping in mind that a function is a set that has no X-repeats, namely the x-coordinate on every pair is never repeated, let's check these ones.

Check the picture below.

Answer:

Step-by-step explanation:

Answer:

x < -6

Step-by-step explanation:

-5x - 8 > 22

Add 8 to both sides:  -5x > 30

Divide both sides by 5:  -x > 6

Divide both sides by -1 (reverse sign):  x < -6

Answer:

x < -6

Step-by-step explanation:

First we want to move all terms not containing x to the right side

-5x > 22 + 8

-5x > 30

Then we want to divide

-5x/5 < 30/-5

30/-5

x < - 6

Answer:

144/169

Step-by-step explanation:

There are 52 cards, 4 are aces, so the probability of not getting ace is 48/52, so we square it, or multiply it by itself to get 144/169

Answer:

1) a = 51, 2) b = 57, 3) c = 53, 4) e = 49 d = 131, 5) f  = 33, 6) g = 79, 7) h = 42 j = 47, 8) m = 59 k = 17 i = 104, 9) n = 55

Step-by-step explanation:

1.

You see that angle HJK has a total degree angle of 115, half of the angle is already stated to be 64 degrees, so you would just have to find the remainder. 115 - 64 = 51

2.

The question follows the same format, when you see the square in the corner it generally means that it is a 90-degree angle.  So following the same steps as last time angle b would be 90 - 33 = 57

3.

Whenever there is a flat line given the angle is equal to 180 degrees, think of it as putting two 90 degree angles back to back. So if they equal 180 angle c would equal 180 - 127 = 53

4

This question is just a little different when you see crossing perpendicular lines angles across from each other equal the same amount, so angle d would be 131. Finding angle e is not hard either, back to question 3 for when it was just a straight line the same logic can be applied here. e would equal 180 - 131 = 49

Step-by-step explanation:

similar ∆les have sides ratio
