A whole triangle is total of 180°

as the two angles are same which is x, hence it is an isosceles triangle.

so using all the angles given,

46° + x° + x° = 180

by collecting all the like terms,

46° + 2x° = 180

GET RID of 46° on the left hand side
ADD of 46° on the right hand side

2x° = 180° - 46°
2x = 134°

now divide all with 2

2x÷2 = 134÷2
x° = 67°

therefore, the answer is x = 67°

5x - 2 = 10 - X Please help

Answer:

x = 2

Step-by-step explanation:

5x - 2 = 10 - x

Add x to both sides

6x - 2 = 10

Add 2 to both sides

6x = 12

Divide both sides by 6

x = 2

By how much does the dependent variable change in response to a change of 1 unit of the independent variable?

dalvyx [7]

Answer: C) 5

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

x = independent variable, y = dependent variable

Assuming this is a linear function, each increase of x by 2 leads to y going up by 10. So 10/2 = 5 is the unit increase each time x bumps up by 1.

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

An alternative is to use the slope formula to get

m = (y2 - y1)/(x2 - x1)

m = (25 - 15)/(4 - 2)

m = 10/2 <--- this expression shows up again

m = 5 <---- leading to the same answer as before

So we see that the slope formula is a more drawn out method to finding the answer.

Rafael wanted to order half a medium pizza at a restaurant. The waiter told him that a medium pizza could be cut into 6 or 8 sli

Nady [450]

Answer:

The wrong in Rafael reason is that 3/6 = 4/8 = 1/2 pizza

Step-by-step explanation:

* Lets explain how to solve the problem

- When we have a quantity we can divided it to many equivalent

fractions

- Equivalent fractions means fractions equal each other

- We can find the equivalent fraction by multiply or divide the two

terms of the fraction by the same number

- Ex: We can divide a circle into two equal parts each part is 1/2 the

circle, if we multiply each term of the fraction by 2 (up and down)

then we will have 2/4 which is equivalent to 1/2 the circle

- Then we can divide the circle by 2 parts with many equivalent fractions

1/2 = 2/4 = 3/6 = ..................

* Lets solve the problem

- Rafael wanted to order half a medium pizza

- The medium pizza could be cut into 6 or 8 slices

∵ The half of 6 is 3/6

∵ The half of 8 is 4/8

- Lets simplify the two fraction

∵ 3/6 = 1/2 by dividing up and down by 3

∵ 4/8 = 1/2 by dividing up and down by 4

∴ There is no difference between the two orders, both of them

equal half the pizza

∴ The wrong in Rafael reason is that 3/6 = 4/8 = 1/2 pizza
