Answer:
a c
Step-by-step explanation:
2+1.25f=10-2.75f Add the variables
2+4f=10 isolate the variable
4f=8
f=2

Answer:
(c) BK = 65
Step-by-step explanation:
Corresponding sides are proportional in similar triangles, so ...
ZT/ZQ = KF/KB
27/(2x +7) = 45/(4x+1)
27(4x+1) = 45(2x +7) . . . cross-multiply
3(4x +1) = 5(2x +7) . . . . divide by 9
12x +3 = 10x +35 . . . . . eliminate parentheses
2x = 32 . . . . . . . . . . . . . subtract 10x+3
x = 16 . . . . . divide by 2
Then the length of BK is ...
BK = 4x+1 = 4·16 +1
BK = 65
A Rational Number is a real number that can be written as a simple fraction (i.e. as a ratio).
Most numbers we use in everyday life are Rational Numbers. gave me thanks
