Find the values of x and y.
Answers
Answer: y = 129, x = 51
Step-by-step explanation:
angles 129 and y are corresponding, so they are equal to each other
y and x are supplementary
so, y + x = 180
x = 180 - y = 180 - 129 = 51
Answer:
I belive y has to be at least 133 because it's just a little bit longer than the 229 one.
And x is most likely to be 125 because if you line up 129 with x, x is should be a little smaller so x should be 125

If R is the midpoint of QS, find QS. QR=2x+16 RS=5x-17
Answers
Answer:
QS = 76
Step-by-step explanation:
Given R is the midpoint of QS, it means the distance from R to each endpoint is equal, that is:
QR = RS
We are given
QR = 2x + 16
RS = 5x - 17
Equating:
2x + 16 = 5x - 17
Subtracting 5x:
2x - 5x + 16 = -17
Simplifying:
-3x +16 = -17
Subtracting 16:
-3x = - 16 -17 = -33
Dividing by -3:
x = 11
Let's find
QR = 2x + 16 = 22 + 16 = 38
The length of QS is double this value: QS = 2*38 = 76
QS = 76

The conversion factor to convert cups to liters is 0.237
Step-by-step explanation:
Given : A table showing conversions for common units of capacity.
Units of capacity
Customary System Units Metric System Units
1 gallon 3.79 liters
1 quart 0.95 liters
1 pint 0.473 liters
1 cup 0.237 liters
We have to find the conversion factor to convert cups to liters.
Consider the given table.
Since, given One cup is equal to 0.237 liters.
So , the conversion factor to convert cups to liters is 0.237
For example to convert 10 cups to liters, we can multiply the number of cups by 0.237 to get cups in liters.
That is 10 cup = 10 × 0.237 = 2.37 liters.
Thus, 10 cups is equal to 2.37 liters.
Hence, The conversion factor to convert cups to liters is 0.237

Classify each of the following statements as true or false where a and b are whole numbers.
a. If GCD(a,b)= 1, then a and b cannot both be even.
b. If GCD(a,b) = 2, then both a and b are even.
c. If a and b are even, then GCD(a,b) = 2.
Answers
b. Is true because a GCD of 2 means that 2 is a factor in both a and b which means that they are both even.
c. is false because even numbers can have a greater factor shared than 2 like how 4 and 8 have a GCD of 4
