16
Step-by-step explanation:
multiply by 2
Answer:
RT = 20
Step-by-step explanation:
Given S is at the midpoint of RT , then
RS = ST , that is
7y - 4 = 2y + 6 ( subtract 2y from both sides )
5y - 4 = 6 ( add 4 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2
Then
RT = RS + ST = 7y - 4 + 2y + 6 = 9y + 2 = 9(2) + 2 = 18 + 2 = 20
Answer:
Try 20.
Step-by-step explanation:
To round 19.5 to the nearest whole number consider the tenths’ value of 19.5, which is 5 and equal or more than 5. Therefore, we have to round up: the whole number part of 19.5, 19, increases by 1 to 20, and the decimal point and all digits (.5) are removed.
19.5 rounded to the nearest whole number = 20
