what is the value of 8 + 2g - 7 when g = 5?​

Complete Question: In the diagram below, <DAB and <DAC are adjacent angles. If m<DAC = 25°, what is m<DAB in degrees? What is m<BAC in degrees?

Answer:

m<DAB = 80°

m<BAC = 105°

Step-by-step explanation:

Generate an equation that will help you find the value of x.

Since m<DAC = 25°, therefore, x - 20 = 25°

Use this equation to find x

x - 20 = 25

Add 20 to both sides of the equation

x - 20 + 20 = 25 + 20

x = 45

m<DAB = 2x - 10

Plug in the value of x

m<DAB = 2(45) - 10 = 90 - 10 = 80°

m<BAC = m<DAC + m<DAB

m<BAC = 25 + 80 = 105°

The product of any two numbers is the result of multiplying them

You can use pencil and paper to get the job done, or use a calculator.

A shortcut is to simply move the decimal over 1 spot to the right.

This is because multiplying 0.017 and 10 is the same as 0.017*10^1, where the exponent of positive 1 means "move decimal point 1 spot to the right". This only works if you multiply by powers of 10.

Answer:

-2b+8c-7a-14

Step-by-step explanation:

You first combine like terms to simplify.

[tex]\boxed{21}[/tex]

When you multiply a negative and a negative, it is going to be a positive number. In this case, we're multiplying -3 and -7, which is equal to 21. If you're not sure of the answer for multiplication problems like this, just use a calculator to check your work.

Hi there! Hopefully this helps!

Answer:

150 children

Step-by-step explanation:

Ratio of adults to children= 8:5

Let the number of adults be 8 units and

the number of children be 5 units.

Total number of people

= 8 +5

= 13 units

Since there are 390 people,

13 units ----- 390 people

1 unit ----- 390 ÷13= 30 people

Number of children= 5 units

5 units ----- 30 ×5= 150 people

Thus, there are 150 children.

Answer:

[tex]f(g(1))=11[/tex]

Step-by-step explanation:

So we have the two functions:

[tex]f(x)=2x+7\text{ and } g(x)=-3x+5[/tex]

And we want to find f(g(1)).

So, let's find g(1) first:

[tex]g(x)=-3x+5[/tex]

Substitute 1 for x:

[tex]g(1)=-3(1)+5[/tex]

Simplify:

[tex]g(1)=-3+5[/tex]

Add:

[tex]g(1)=2[/tex]

So:

[tex]f(g(1))=f(2)[/tex]

Now, substitute 2 for x in f(x):

[tex]f(x)=2x+7\\f(2)=2(2)+7[/tex]

Multiply:

[tex]f(2)=4+7[/tex]

Add:

[tex]f(2)=11[/tex]

So:

[tex]f(g(1))=11[/tex]

Answer:

Answer:

-12

Step-by-step explanation:

Since we want to find g(9), we will use the function g(x):

[tex]g(x)=-2x+6[/tex]

Substitute:

[tex]g(9)=-2(9)+6[/tex]

Multiply:

[tex]g(9)=-18+6[/tex]

Add:

[tex]g(9)=-12[/tex]

So, our answer is -12 :)

Answer:

8x^2+5y+1

Step-by-step explanation:

1+x^2-3+2y+7x^2+3+3y

Combine like terms

x^2+7x^2+2y+3y+3+1-3

8x^2+5y+1

Answer:

8x^2 + 5y + 1

Step-by-step explanation:

1 + x^2 - 3 + 2y + 7x^2 + 3 + 3y

group like terms

= x^2 + 7x^2 + 2y + 3y + 1 - 3 + 3

add similar items

= 8x^2 + 2y + 3y + 1 - 3 + 3

add similar items

= 8x^2 + 5y + 1 - 3 + 3

= 8x^2 + 5y + 1

Answer: 0.5

Step-by-step explanation:

Add 3/16 to both sides to isolate the variable on one side. Then the equation should be x=8/16 which is 0.5.

Answer:

Volume of cone = 40 in³

Step-by-step explanation:

Given:

Volume of cylinder = 120 in³

Height of cylinder = Height of cone

Radius of cylinder = Radius of cone

Find:

Volume of cone

Computation:

Volume of cylinder = πr²h = 120 in³

Volume of cone = (1/3)πr²h

So,

Volume of cone = (1/3)(120)

Volume of cone = 40 in³

Step-by-step explanation:

Givem that Marta has 1 cubic yard of sand to build a wall in the shape of a rectangular prisim that is 10 inches tall and 5 inches wide to the nearest foor 

1 cubic yard = 46656 cubic inches

Volume = Length × width × height

Substitute all the parameters

46656 = 10 × 5 × height

46656 = 50 height

Height = 46656 / 50

Height = 933.12 inches

Answer:

The linear function with the smallest slope must be multiple of one of the other two linear functions if all functions are coplanar. Otherwise, they intersect at the given point in space.

Step-by-step explanation:

A system of two linear functions with two variables have an unique solution on a given plane, as there are three linear function, it means that linear function with the smallest slope must be multiple of one of the other two linear functions.

But, if those functions are not all coplanar and have 3 variables, they intersect at the given point.

Answer:

250.50 - 35m = 300 - 45.25m

Step-by-step explanation:

Whenever an equation asks for when it will take x (or m in this case) amount of things or time you should know that there will be 2 different equations that have to equal each other

The equation will be 250.50 - 35m = 300 - 45.25m

The 35m is being subtracted from 250.50 because they are losing money each time they spend. This also applies to 45.25m

Also 35m and 45.25m are variables because it says they spend that much money each month. They don't specify how many months, so we have to put a variable after it.

Answer:

b) 250.5 – 35m = 300 – 45.25m

Answer:

( p - 4 ) ( p - 12 ) = 0

Step-by-step explanation:

To factor this equation, let's apply the quadratic formula.

p^2 - 16p + 48 = 0

Let a = 1, b = -16, c = 48

[-b +/- sqrt(b^2 - 4(a)(c))] / 2 (a)

[- (-16) +/- sqrt( (-16)^2 - 4(1)(48)) ] / 2 (1)

= [ 16 +/- sqrt( 256 - 192) ] / 2

= [ 16 +/- sqrt(64) ] / 2

= [16 +/- 8] / 2

p = (16 + 8) / 2 ; p = (16 - 8) / 2

p = 24 / 2  ; p = 8 / 2

p = 12  ;  p = 4

Hence, this equation factors into the following:

( p - 4 ) ( p - 12 ) = 0

Hello there! :D

Today we're gonna learn some math, whoopie!

Alright, so we want to know how many 2/3 cups can go into 9 cups!

Firstly, I want to turn 9 cups into a fraction with the denominator of 3.

Let me do it all fancy for you:

[tex]9=\frac{x}{3}[/tex]

We know we want the denominator to be three, now we just need to do the opposite action (multiplication) to the other side to find what "x" is!

[tex]9*3= \frac{x}{3}*3[/tex]

If you have trouble understanding that step, let me know!

[tex]x=27[/tex]

Enter that into the fraction and we have:

[tex]\frac{27}{3}[/tex]

Notice that 27 is not an even number!

Now, we can the numerator of 27/3s and divide it by the numerator of 2/3s.

[tex]27/2=13.5[/tex]

This is not a whole answer, but the question is asking how many 2/3 cups can go into nine cups. Half of a 2/3 cup does not equal a 2/3 cup, so the answer would be 13 cups.

I hope this helps you can you have a wonderful day,

The number of 2/3 cups that can go into 9 cups is [tex]13\frac{1}{2}[/tex]

Total number of cups = 9

The number of 2/3 cups we can get from 9 cups = x

To get the number of 2/3 cups in 9 cups, we will divide 9 by 2/3

Number of 2/3 cups in 9 cups = 9 ÷ 2/3

Number of cups in 9 cups = 9  x  3/2

x   =  27/2

x  =  13.5

The number of 2/3 cups that can go into 9 cups is [tex]13\frac{1}{2}[/tex]

Let's start with the smallest prime number 2

60/2 = 30

Divide that result over 2

30/2 = 15

We can't divide this by 2 because 15/2 = 7.5 isn't a whole number

Let's move onto 3

15/3 = 5

The result is a prime number, so we stop.

The values we divided as denominators were: {2, 2, 3}

We add the result 5 to the set to completely list all of the prime factors of 60

The prime factorization would be
