Answer:

x+74

Step-by-step explanation:

Answer:

x=42

Step-by-step explanation:

The degree that added up in a triangle is 180°. Thus, you set up the equation to solve for x.

93+45+x=180

add 93+45=138

subtract both side 138 which get you

x=42

Answer:

1 5 and 8 also equal 130

2 3 6 and 7 equal 50

Step-by-step explanation:

have a great day :D

Answer:

∠1= 130°

∠2= 50°

∠3= 50°

∠4= 130°

∠5= 130°

∠6= 50°

∠7= 50°

∠8= 130°

Step-by-step explanation:

angles 1&2 have to equal 180°

and so on for ∠3&4  and 5&6 and 7&8

180-130=50

Answer:

1) 63x²+68x+12=0

2) x⁴-8x²+15=0

3) -5x²-(5/x²)+26=0

Step-by-step explanation:

1)

x=-6/7 and x=-2/9

7x=-6 and 9x=-2

7x+6=0 and 9x+2=0

(7x+6)(9x+2)

63x²+14x+54x+12

63x²+68x+12=0

2)

x=√3 and x=√5

x²=3 and x²=5

x²-3=0 and x²-5=0

(x²-3)(x²-5)

x⁴-5x²-3x²+15

x⁴-8x²+15=0

3)

x=[tex]\sqrt[2]{5}[/tex] and x=[tex]\sqrt[-2]{5}[/tex]

x²=5 and x⁻²=5

x²=5 and (1/x²)=5

x²-5=0 and (1/x²)-5=0

(x²-5)((1/x²)-5)

1-5x²-(5/x²)+25

-5x²-(5/x²)+26=0

Step-by-step explanation:

Answer:

18a^2

Step-by-step explanation:

Multiply the numbers together. Multiply the variables together.

(-3a)(-6a) = (-3) * (-6) * a * a = 18a^2

-3 times -6 = 18 since negative times negative is positive, and 3 * 6 = 18.

Also a * a = a^2.

Answer: 18a^2

Answer:

she has 15 pieces

Step-by-step explanation:

it's as simple as 5*3

First we clear brackets

 -r+s+s-r

Second we collect like terms

-r-r+s+s

then we add it

-2r +2s

if we read the question it says standard form so we out the G.C.F of the

expression

Answer:

$15

Step-by-step explanation:

Given data

Principal= $150

Rate= 5%

Time= 2 years

The simple interest expression is given as

A=P(1+rt)

substitute

A= 150(1+0.05*2)

A= 150(1+0.1)

A= 150*1.1

A= $165

Hence the amount received in interest is

=165-150

=$15

Answer:

y = 60 ; x = 12

Step-by-step explanation:

The 60° angle and y are equal. Therefore, y = 60.

The parallel lines are equal to each other. You can solve for x by making an equation.

x + 3 = 15

x = 12

Answer:

3y - 6x -6xy + 9-8z

Step-by-step explanation:

here's your solution

=> -6y -14 -(-8yz) - 6x + 23 + 9y - 8z + 2zy

=> put like term together

=> -6y +9y -6x-8yz+2zy+23-14

=> 3y - 6x -6xy + 9-8z

hope it helps

hope it helps

Answer:

3y + 10yz - 6x - 8z + 9.

Step-by-step explanation:

-6y – 14 - (-8yz) - 6x + 23 +9y - 8z + 2zy

Bring like terms together:

=  9y - 6y + 2yz - (-8yz) - 6x - 14 + 23 - 8z

=  9y - 6y + 2yz  + 8yz - 6x - 14 + 23 - 8z

Now simplify:

= 3y + 10yz - 6x - 8z + 9.

Answer: 16

Step-by-step explanation:

multiplying by negative exponents can be a little tricky. So (1/4x)^-2 becomes 16/x^2 = __/x^2 so the missing number is 16

Step-by-step explanation:

Answer:

Sin Z = 8/17

Tan G = 15/8

Cos Z = 15/17

Sin M = 1

Step-by-step explanation:

Sin is equivalent to Opposite over Hypotenuse. For Z, the opposite would be 40. 85 is always the hypotenuse in this problem.

Sin Z = 40/85, simplified it is 8/17

Tan is opposite over adjacent. In this case, the opposite is 75. The adjacent is 40.

Tan G = 75/40, simplified it is 15/8

Cos is adjacent over hypotenuse. In this one, the adjacent is 75. The hypotenuse is 85.

Cos Z = 75/85, simplified it is 15/17.

In Reference to what I said above Sin, I will use the same thing.

Sin M = 1

85/85

Answer:

x = -1

Step-by-step explanation:

Solve the equation -2(x + 4) = -6

Solving for the above Equation, we have to find x

-2(x + 4) = -6

We expand the brackets

-2x - 8 = -6

We collect like terms

-2x = -6 + 8

-2x = 2

x = 2/-2

x = -1

Answer:

Let y be the no. of people she can bring

18 + 16.5y <= 150

Step-by-step explanation:

Answer:

16.5y + 18 = 150

16.5y + 18 = 150

        -18    -18

        0       132  

          16.5y     132

          16.5       16.5

y = 8

Ms.Lemon can bring 8 people including herself

Step-by-step explanation:

First you are going to rewrite the equation then do the inverse operation of addition. Then, subtract 150 from 18 then you get 132 then you bring down 16.5y and cancel it out by dividing and then you divide 132 by 16.5 and you get 8 so Ms.Lemon can bring 8 people including her self.
