Answer:
∠ RST = 72°
Step-by-step explanation:
∠ RST and 4x - 24 are alternate exterior angles and congruent, thus
4x - 24 = 3x ( subtract 3x from both sides )
x - 24 = 0 ( add 24 to both sides )
x = 24
Thus
∠ RST = 3x = 3 × 24 = 72°

Taylor bought a necklace for each of her three sisters. She paid $7.50 for each necklace. Supposed she had $9 left. How much money did she have initially to spend on each sister?
Answers
Answer:
7.50 x 3= 22.50
22.50+9= 31.50
Step-by-step explanation:
If each necklace was $7.50 and she got one for each of her 3 sisters then we need to multiply $7.50 by 3. Finally, she has $9 left over. So if we add the total she spent on the necklaces and the 9 she has left over then we will get the total she started with.

The average typing speed of Joseph in words per minute is 45 words per minute.
What is an average speed?The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.
Now it is given that,
Number of words = typed 60 words
Time taken = 1 and 1/3 minutes
⇒ Time taken = 4/3 minutes
Thus, Average typing speed = Number of words / Time taken
⇒ Average typing speed = 60 / (4/3) words per minute
⇒ Average typing speed = 45 words per minute
Thus, the average typing speed of Joseph in words per minute is 45 words per minute.

2(x+5)=3x+1
Answers
Answer:
x = 9
Step-by-step explanation:
2(x + 5) = 3x + 1
open the parenthesis
2x + 10 = 3x + 1
subtract 2x from both sides of the equation
2x - 2x + 10 = 3x - 2x + 1
10 = x + 1
subtract 1 from both sides of the equation
9 = x
Answer:
Step-by-step explanation:
Substitute
2x+10=3x+1
Subtract 3x to other side
-x+10=1
Subtract 10
-x=-9
divide -1 both sides
x= 9
