Find the values for x, y, and z.

Answer : 52

Explaination :

(5x+2)+(2x+18)+90=180

5x+2x+2+18+90=180

7x+110=180

7x = 180-110

7x = 70

x = 70÷7

x = 10

Angle CDF

= 5(10)+ 2

Answer:

Some functions do not have inverse functions. ... If f had an inverse, then its graph would be the reflection of the graph of f about the line y = x. The graph of f and its reflection about y = x are drawn below. Note that the reflected graph does not pass the vertical line test, so it is not the graph of a function.

Answer:

b

Step-by-step explanation:

y = 1y

1y+0.4y =1.4y

Answer:

b. (1.4y)

Step-by-step explanation:

When a variable has no number next to it, it is always going to be 1 multiplied by the variable. adding 1y and 0.4y would make 1.4y.

Answer:

4x+3=6+x

x=1

Step-by-step explanation:

4x+3=6+x

3x+3=6

3x=3

x=1

Answer:

number is 1

Step-by-step explanation:

lets say the number is x. So, 4x+3=x+6 we can then subtract 3 from both sides and get 4x=x+3 then we can subtract x from both sides. So we get 3x=3. We divide both by 3 and get 1

Answer:

5(3t+2) + 7(2t+5)

Step-by-step explanation:

because for each of the 3t+2 tickets you make $5 and for each of the 2t+5 tickets you make $7

Answer:

3/10 or 30%

Step-by-step explanation:

the probability of a...

writer = 13/30

painter = 9/30 or 3/10

musician = 6/30 or 1/5

photographers = 2/30 or 1/15

Answer:

$125

Step-by-step explanation:

because 3 is less than 5 you round down and 1 will still be there and less than 5 so round down again which leaves you with a whole number of 125

hope this helps :)

Answer:

$125

Step-by-step explanation:

For $125 to round to $126 the number the decimal would have to be .5, and .13 is less than .5, so the number rounds down to $125.

I hope this helps, and have a great day! :)

Answer: 7

Step-by-step explanation:

11 1/2 - 4 1/2 = 7

Answer: A scale model is a representation or copy of an object that is larger or smaller than the actual size of the object being represented. Very often the scale model is smaller than the original and used as a guide to making the object in full size.

Answer:

16°

Step-by-step explanation:

so 10 degrees warmer from 8 to noon

so

-14°+10°= -4°

so at noon, it was -4°

but then from noon to 4 pm, the temp change was twice that

so

10° x 2= 20°

so

-4° + 20° = 16°

temp at 4 pm was 16°

Answer:

x^2 + y^2 = 256

good luck and have an awesome Day/Night

Answer:

20

Step-by-step explanation:

For the sake of the problem, let's make female workers "x" and male workers "y".

x+y<40       This equation shows that the total number of workers has a max of 40.

30x+20y<1,000      This equation shows that the total cost the manager pays ($30 to each woman, $20 to each man) has a max of $1,000.  

Now you can solve for x and y.

X+y<40

-y       -y

X<-y+40

Substitute -y+40 in for X in the second equation

30(-y+40)+20y<1,000      

-30y+1200+20y<1,000         Distribute

-10y+1,200<1,000      Combine like terms

-10y<-200                   Subtract 1,200

y>20                Divide by -10; flip the sign

Since y>20, and y=male workers, you now know that the minimum

number of male workers he should send is 20

Answer:

Parenthesis

Step-by-step explanation:

You need parenthesis to write around a pair of coordinates.

For instance, you would write (5,7) instead of 5,7

The 5 is the x coordinate and 7 is the y coordinate. It tells us the exact location on the xy grid system. Think of it like an address or longitude/latitude.

Answer:

-2.5

Step-by-step explanation:

The slope is the rate.

Answer:

3.25 ft

Step-by-step explanation:

A = bh

A = (2.5)(1.3)

A = 3.25

Answer:

3.25 ft

Step-by-step explanation:

A =bh

A =(2.5)(1.3)

A =3.25

Step-by-step explanation:

Answer:

x=8

Step-by-step explanation:

10x-20=7x+4

This is because the two angles are vertical.

10x-7x=4+20

3x=24

x=8

Answer:

x = 8

Step-by-step explanation:

10x - 20 = 7x + 4

3x = 24

x = 8

Answer:

7.5

Step-by-step explanation:

15/2=7.5

Answer:

2n=15

Step-by-step explanation:

2n=15

n=15/2 (as we know multiply change to divide)

n=7.5

Answer:

V≈1470.27

Step-by-step explanation:

V=πr2h=π·62·13≈1470.26536

Answer:

(3, 1)

Step-by-step explanation:

Let the coordinates of B be (x, y)

Since, M is the midpoint of AB.

Therefore, by mid point formula:

[tex]1 = \frac{ - 1 + x}{2}, \: \: \: 3 = \frac{5 + y}{2} \\ \\ 2 = - 1 + x, \: \: \: 6 = 5 + y \\ \\ 2 + 1 = x, \: \: \: 6 - 5 = y \\ \\ 3 = x, \: \: \: 1 = y \\ \\ x = 3, \: \: \: y = 1 \\ \\ B = (3, \: \: 1)[/tex]

Answer:

Step-by-step explanation:

It is not A  because books + magazines is related to the 6

It is not C  because books cost $5.5 and magazines cost $3

B and D are very similar, but is is not D because the ≤ $40 is incorrect since it clearly states that Bonney will spent less than 40   < 40

so that leaves B     <<<-------------

     5.5b + 3m < 40       5.5 times books plus 3 times mags will be less than 40

       b + m ≥ 6              the total number of books plus mags will be at least 6

                                    or could be more 6
