Answer:
x=40°
Step-by-step explanation:
Every triangles area equals 180
75+65=140
180-140=40
Answer:
40
Step-by-step explanation:
All angles in a triangle add up to 180°.
65° + 75° + x° = 180
140° + x° = 180°
-140 -140
x° = 40°

You have 59 total coins in a jar on your nightstand at home. The total amount of money is $12.05. You only have quarters and dimes. How many of each type of coin do you have? (hint - use a different method to write and solve the system).

Answer:
41 quarters18 dimesStep-by-step explanation:
When there are two contributors to the mix, it usually works well to let a variable represent the quantity of the larger contributor. Here, that larger contributor is the quarter.
Let q represent the number of quarters. Then 59-q is the number of dimes. The value of the coins, in cents, is ...
25q +10(59 -q) = 1205
15q +590 = 1205 . . . . . . . . eliminate parentheses, collect terms
15q = 615 . . . . . . . . . . . subtract 590
q = 41 . . . . . . . . . . divide by 15
59-q = 59 -41 = 18 . . . . . number of dimes
You have 41 quarters and 18 dimes.

Step-by-step explanation:
An African elephant weighed 209 lbs when it was born. Baby elephants gain an average of 38 lbs per week.
Part A
Write an equation that could be used to calculate the number of weeks, w, it would take a baby elephant to weigh 1197 lbs.
Part B
How many weeks will it take for the baby elephant to weigh 1197lbs?
Enter your equation, your answer, and your work or explanation in the space provided.
Answers
Answer:
Part A: W= (1197- 209)/ 38
Part B: 26 Weeks
Step-by-step explanation:
Part A:
We first need to subtract the 209lbs from the goal of 1197lbs. Now we have how many pounds we need to gain. Then we need to divide it by how many pounds we are gaining a week. Now we have how many weeks it will take
Part B:
W= (1197- 209)/ 38
W= 988/ 38
W= 26

Complete question :
Liz's math test included a survey question asking how many hours students spent studying for the test. The scatterplot and regression line below show the relationship between how many hours students spent studying and their score on the test.
The fitted line has a slope of 15.
What is the best interpretation of this slope?
Answer:
C.)
The model predicts that the score will increase 15 points for each additional hour of study time.
Step-by-step explanation:
The slope of a regression line represents the rate of change :
From the formula :
Rise / Run = (y2 - y1) / (x2 - x1).
The slope is a Coefficient which shows how much the dependent variable changes per unit change in the independent variable.
Hence, for a slope value of +15, which is positive, meaning an increase ; then the score obtained will increase by 15 per additional unit increase in hour of study.

Answer:
You're wrong, it's the bottom left
Step-by-step explanation:
x^2-49 is a difference of squares so it factors into (x+7)(x-7) which obviously cancels out with the denominator leaving x-7 left. This is the line you should graph, but keep in that x+7 is still in the denominator so x cannot be equal to -7 which means that this point should be be on the line which leaves the answer to be the one on the bottom left.
