Find the value of x​

Answer:

Sorry do not have your answer

Step-by-step explanation:

Hey there!

5x - 50 + 2x + 80 - x = 180

COMBINE the LIKE TERMS

= 6x + 30 = 180

SUBTRACT 30 to BOTH SIDES

6x + 30 - 30 = 180 - 30

CANCEL out: -30 - 30 because that gives you 0

KEEP: 180 - 30 because it helps solve for the x-value

6x = 180 - 30

180 - 30 = 150

NEW EQUATION: 6x = 150

DIVIDE 6 to BOTH SIDES

6x/6 P 150/6

CANCEL out: 150/6 because that gives you the result of the x-value

x = 150/6

SIMPLIFY IT!

x = 25

Therefore, your answer is: x = 25

Good luck on your assignment and enjoy your day!

Answer:

1) x=1/2-y/2-3z

2)x= 16/3- 2y/3- 5z/3

3)x= 11/7- 3y/7+ 4z/7

Step-by-step explanation:

isolate the variable, to do that divide each side by the factors that don't contain the variable

Answer: 16lbs

Step-by-step explanation: CCC=Chocolate Chip Cookie; WCC=White Chocolate Cookie.

Set up a table showing the pricing ($/lb) and pounds (lbs) for both cookies. The total value of the WCC is $23.8 ($5.95/lb x 4 lbs). The value of the CCC is 6.95x, where x is the lbs CCC.

CCC WCC

6.95 5.95 $/lb

x 4 lbs

6.95x 23.8 $ Total value [$/lb * lbs]

We want x lbs of CCC cookies such that the total value of cookies divided by the total number of lbs is equal to $6.75/lb. That can be written as:

(6.95x + 5.95*4)/(x+4) = 6.75 [Total value of cookies divided by total weight equals $6.75]

(6.95x + 23.8)/(x+4) = 6.75

6.95x + 23.8 =6.75x + 27

0.2x = 3.2

x = 16 lbs

We need 16 lbs of CCC added to the 4 lbs of WCC for a total weight of 20 lbs and a price of $6.75/lb.

Answer:

Read explanation

Step-by-step explanation:

First you put a point on (0,5).  Then you perform rise/run which is the slope.  The slope is 2.  So from (0,5) you go up 2 and to the right one and make another point.  You then use a ruler and draw a line connecting them and put arrows at the end.

Answer:

14 10 cent coins

Step-by-step explanation:

Assumption method:

Assume all are 10 cent

10x48=$4.80

8.20-4.80=3.40

10x47=$4.70

1x20=$0.20

$4.70+$0.20=$4.90

Gap= $3.40

Difference=$4.90-$4.80=$0.10

Gap÷Difference= $3.40÷0.10=34 20 cent coins

48-34=14 10 cent coins

I think its like this.

Answer: sqrt 91

Step-by-step explanation:

We can substitute in y here as 30, so that 60+102=2x^2

182=2x^2

In the order of operations, it states that exponents comes before multiplication

91=x^2

So x will be the square root of 91

Answer:

neither

Step-by-step explanation:

put the first equation in slope intercept form

x-2y=-1

-2y= -x -1

y = 1/2x +1/2

the slope is not the same, and it is not the opposite, so it is neither

An exponential function is represented as: [tex]\mathbf{f(x) = ab^x}[/tex]

The value of f(1) is 3.95

f(-2) = 1 means that:

[tex]\mathbf{ab^{-2} = 1}[/tex]

f(7) = 63 means that:

[tex]\mathbf{ab^{7} = 63}[/tex]

Divide both equations

[tex]\mathbf{\frac{ab^7}{ab^{-2}} = \frac{63}{1}}[/tex]

Apply law of indices

[tex]\mathbf{b^9 = 63}[/tex]

Take 9th root of both sides

[tex]\mathbf{b =1.58}[/tex]

Make a, the subject in [tex]\mathbf{ab^{-2} = 1}[/tex]

[tex]\mathbf{a = \frac{1}{b^{-2}}}[/tex]

[tex]\mathbf{a = b^2}[/tex]

Substitute [tex]\mathbf{b =1.58}[/tex]

[tex]\mathbf{a = 1.58^2}[/tex]

[tex]\mathbf{a = 2.50}[/tex]

So, we have:

[tex]\mathbf{f(x) = ab^x}[/tex]

[tex]\mathbf{f(x) = 2.50 \times 1.58^x}[/tex]

Substitute 1 for x

[tex]\mathbf{f(1) = 2.50 \times 1.58^1}[/tex]

[tex]\mathbf{f(1) = 3.95}[/tex]

Hence, the value of f(1) is 3.95

Answer:

X= 15, m∠78°

Step-by-step explanation:

Since the angles are vertically opposite

Therefore their measurements are equal

Therefore (2x + 48 ) = (5x + 3 )

So,

[tex](2x + 48) = (5x + 3)\\(2x-5x)= (3-48)\\-3x = -45\\x = -45/-3\\x = 15[/tex]

[tex](2x + 48)\\=( 2* 15 + 48)\\= 30 + 48\\=78\\\\(5x + 3)\\=(5*15 + 3)\\=75+3\\=78[/tex]

They both equal 78°
