the hypotenuse and the leg of the first right angle are congruent to the other triangle's.

Answer:

x = 8

Step-by-step explanation:

( 6x + 1 ) + 90 + ( 5x + 1 ) = 180

6x + 1 + 90 + 5x + 1 = 180

11x = 88

x = 8

Answer:

a) 63

Step-by-step explanation:

Answer:

$2.25

Step-by-step explanation:

Let c represent the price of cheese pizza and let p represent the prize of pepperoni pizza

3c + 2p= 11.75

2c + 1p = 7

Solve using elimination method

3c + 2p= 11.75 × 2

2c + 1p = 7 × 3

6c + 4p = 23.5

-

6c + 3p = 21

p = 2.5

Substitute 2.5 for p in equation 1

3c + 2p= 11.75

3c + 2(2.5) = 11.75

3c + 5 = 11.75

3c = 11.75-5

3c = 6.75

c= 6.75/3

c= 2.25

Hence the price of one slice of cheese pizza is $2.25

Answer:

$2.25

Step-by-step explanation:

Answer:

1/2x+5=10

subtracting 5 from both sides 1/2x+5-5=10-5

1/2x=5

divide both sides by 1/2

1/2x÷1/2=5÷1/2

x=5×2/1

x=10

Answer:

it should be an 8

Step-by-step explanation:

The initial value in this question y = 8x+6 will be 8 .

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

The equation is given as;

y = 8x+6

We can see that the equation contains two terms that are 8x and 6.

The initial value is the first number of the first term in the equation.

Here, the first term is 8x.

Hence, the initial value in this question y = 8x+6 will be 8 .

so basically you have to look for the opposite side of what they give you. then just plot it in

Answer:

Yes they are similar because of SAS similarity

Step-by-step explanation:

the side lengths are proportional to each other, and the angle in the middle of the sides is the same size, therefore it has Side Angle Side (SAS) similarity.

ΔTSR ~ ΔFEG by the SAS Similarity Theorem

SAS Similarity Theorem states that two triangles with two pairs of proportionate sides and a pair of included angle are similar to each other.

In the image given, the two triangles have:

This means they are similar by the SAS Similarity Theorem.

Therefore, ΔTSR ~ ΔFEG by the SAS Similarity Theorem.

Answer:

[tex]24x^{2} +7x^{2} =[/tex]

step-by-step explanation:

You have to solve this to get your answer. This is a case where you have to use the pythagorean theorem.

Answer:

this is a right angle triangle.

which means that we can use hypotenuse theorem to solve it.

the hypotenuse theorem:-

a^2 +b^2 =c^2

where a and b are the sides opposite to the hypotenuse.

[(the longest side) the longest side of the triangle is always opposite to the right angle]

so...

a = 24

b = 7

a^2 + b^2 = c^2

24^2 + 7^2 = c^2

576 + 49 = c^2

625 = c^2

don't stop here, you could lose marks. I have seen my classmates do this silly and small mistake and lose 1/2 a mark.

√625 = c

25 = c

thus the length of the third side is 25.

Answer:

3 hours

Step-by-step explanation:

Total cost = 144 + 80h

Where h = number of hours

How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?

384 = 144 + 80h

Subtract 144 from both sides

384 - 144 = 144 + 80h - 144

384 - 144 = 80h

240 = 80h

Divide both sides by 80

h = 240 / 80

= 3

h = 3 hours

Step-by-step explanation:

Each of the coordinates of B(1, -5) is multiplied by the scale factor, 0.5:

  B' = (0.5·1, 0.5·(-5)) = (0.5, -2.5)

The coordinates of B' are (0.5, -2.5).

Answer:

i would say the answer is 20 + 6i but thats not an answer

-1 + 21 = 20

and

i + 5i = 6i

so
