Answer:
sexual reproduction provides evolutionary advantages to organisms that employ this mechanism to produce offspring.
Step-by-step explanation:
Answer:
a. y = 6
b. RS = 44
ST = 37
RT = 81
Step-by-step explanation:
RS = 7y + 2
ST = 5y + 7
RT = 14y - 3
find:
a. y
b. RS, ST, RT
RS + ST = RT
7y + 2 + 5y + 7 = 14y - 3
group like terms
7y + 5y + 2 + 7 = 14y - 3
12y + 9 = 14y - 3
9 + 3 = 14y - 12y
12 = 2y
y = 12/2
y = 6
-----------------------------------
b.
RS = 7(6) + 2
RS = 44
ST = 5(6) + 7
ST = 37
RT = 14(6) - 3
RT = 81
Answer:
Adding means to, add two or more numbers together to get the sum.
NOTE: If it says sum that's adding.
Subtracting means to, minis the first number from the second number to get the difference.
NOTE: if it says difference that's subtracting.
