--------------------------------------------------

Step-by-step explanation:

60+x-45+x=180

60-45+2x=180

15+2x=180

2x=180-15

2x=165

x=165/2

x=82.5

Answer:

x = 82.5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

x + x - 45 + 60 = 180, that is

2x + 15 = 180 ( subtract 15 from both sides )

2x = 165 ( divide both sides by 2 )

x = 82.5

Answer: Each can of soda costed $1.50

Step-by-step explanation:

The total cost was $8

Xavier's bought 4 snacks; each $1.25

4 x 1.25 = $5

How much for 2 cans of soda?

Well we know how much the snacks were ($5) and the total cost was $8, so the 2 cans costed $3 because 5 + 3 = 8. But how much did each can cost? Each can costed $1.50 because if the 2 cans costed $3, and we wanted to know how much 2 costed, we would have to divide 3 by 2 which is 1.50. So each can costed $1.50

Answer:

x=6

Step-by-step explanation:

3x-6=12

   +6 +6

3x=18

3x/3= 18/3

x=6

Hope this helps!

Answer:

x=6

Steps

3x - 6 = 12

add 6 to both sides

3x - 6 + 6 = 12 + 6

simplify

3x = 18

Divide both sides by 3

3x/3 = 18/3

simplify

x=6

Answer:

There is no word "tyyy"

Step-by-step explanation

It does not exist in this pitcute.

Answer:

(0, -2)

Step-by-step explanation:

The slope equation is written as y = mx + b where m is the slope and b is the y-intercept. In this equation the slope, which is m, is -2/3 and the y-intercept is -2, which is the value of b. So the y-intercept on the graph would be found at point (0, -2)

Let y = mx +b, where m is the slope of the equation and b is the y-intercept.

So from the equation [tex]y=-\frac{2}{3}x-2[/tex] You'd find the y-intercept at (0,2). Alternative way, you can find the y-intercept by substituting x = 0 so -2x/3 will be 0 because x = 0 and -2x(0)/3 = 0-2 = -2.

So from the y = mx + b, you would find the y-intercept at (0,b)

Answer:

the answer is c 11.26 just subtract from the actual number

First we must write down the information given

1. The store is selling 4 bags of bananas

2. 4 bags of bananas cost 22.52

3. We need to find the cost of 2 bags of bananas

If we know that 4 bags of bananas cost 22.52, and we know that we need 2 bags. We also know that 4 / 2 = 2

So, what we need to do is divide the cost of 4 bags by 2.

22.52 / 2 = 11.26

Which means, that the cost of 2 bags is C.

Answer:

55.22 salamanders

Step-by-step explanation:

Z score formula is given as:

Z score = x - μ/σ

x = 16.8 cm

μ = mean = 15cm

σ = standard deviation 2cm

Z score = 16.8 - 15/2

= = 0.9

Probability value from Z-Table:

P(x<16.8) = 0.81594

P(x>16.8) = 1 - P(x<16.8)

1 - 0.81594

= 0.18406

In a collection of 300 salamanders, about how many have length greater than 16.8cm?

= 300 × 0.18406

= 55.218 salamanders

Approximately to the nearest hundredth = 55.22 salamanders

Therefore, 55.22 salamanders have length greater than 16.8cm

(2)(x)+(2)(−4)+8=18(Distribute)

2x+−8+8=18

(2x)+(−8+8)=18(Combine Like Terms)

2x=18

2x=18

Step 2: Divide both sides by 2.

2x÷2=18÷2

x=9

Answer:

48 : 42

Step-by-step explanation:

1. Whatever you do to one side of the ratio you do to the other.

2. If there are 42 forks, then the ratio then looks like this: x : 42

3. One side of the ratio was multiplied by six.

4. Do the same to the other and you get 48 : 42

Hope this helps ~

Answer:

48 knives

Step-by-step explanation:

The original ratio is 8:7

Our ratio now, looks like this k:42 (k is just a variable)

First, divide 42 by 7 and you'll get 6.

Multiply 6 by 8 and you'll get a product of 48.

Our new ratio should look like this 48:42

There are 48 knives.

Answer:

The graph of f is shifted 1 unit down to create the graph of g.

Step-by-step explanation:

i took the test earlier and got this answer

The linear parent function f(x) = x is reflected over the x-axis to create the grap of g(x) = - f(x).

There are four different kinds of translation: stretching, shrinking, rotating, and shifting.

When shifting, the entire graph is moved in the XY direction. When expanding and contracting a graph, we do so by a factor of k. When rotating a graph, we do so either clockwise or counterclockwise.

We know that when we change the sign of x in a function it is rotated about

the y-axis and when we change the sign of y in a function it is rotated about the x-axis.

f(x) = y = x and g(x) = - f(x) = - y.
