The exterior angle is = to the 2 interior angles.
83 = (9x + 4) + (4x + 1) Remove the brackets
83 = 9x + 4 + 4x + 1 Group the like terms
83 = 9x + 4x + 4 + 1 Add the like terms.
83 = 13x + 5 Subtract 5 from both sides.
78 = 13x Divide by 13
78 / 13 = x
x = 6
So They want the angles
9x + 4 = 9*6 + 4 = 58
4x + 1 = 4*6 + 1 = 25
When you add these two together you should get 83. Do you?
Answer: B

Answer:
Use the equation 250+25w=400+20w
Step-by-step explanation:
Replace w with one of the answers until you get the right one.
pretty sure its 35 but I don't have a calculator with me so double check
Answer:
Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.
- Relationship between the variables are
- (a) As the age increases, the height increases.
- No relationship between variables.
- (a) As the age increases, height decreases.
- (b) As the height decreases, the age decreases.
Step-by-step explanation:
- If visually found a child born till his age of elder he has increased.
- It is clearly true that as the age increases height increases.
- Child is born at some point of time with a particular height.
- It is never an association between age increases and height reduces.
- Age is again started at some point of time, it cannot decrease.
- After descriptive statistics there something called predictive.
- Describing the data is one way of understanding statistics.
- It is mean,median mode where the particularly number stands.
- Predictive is the next stage an association of variables.
- Variables are very important in analysis it basically attribution.
- In order to find any analyse test studies are important variables to.
