Answer:
Step-by-step explanation:
Note that the entire segment RT is the combined lengths of RS and ST. So:
We know that RT is 108, RS is (9y+5), and ST is (3y+7). Substitute:
On the right, combine like terms:
Add:
Subtract 12 from both sides. The right cancels:
Divide both sides by 12:
So, the value of y is 8.
To find RS and ST, substitute 8 for y. So:
Substitute 8 for y:
Multiply:
Add:
Do the same for ST:
Substitute 8 for y:
Multiply:
Add:
Answer: 96 miles
Step-by-step explanation: 120 divide by 55= 2.18. So you multiply 44 by 2.18
Answer:
f = (1/2)(m), for m = 1
f = (1/2)(1)
Step-by-step explanation:
Answer:
use the formula a^3+b^3= (a+b)-3ab(a+b)
in above question assume (a+b) as a and 1 as b
later in (a+b+1) take (a+b) as a and 1 as b
and use the formula (a+b)^2 = a^2+2ab+b^2
