Simplify: -4a^-(6a-2)+3(a^-1) With the ^ being (2)...
Answer: -a^ -6a -1
The ^ = 2
First multiply the big numbers. 3*1.20= ($3.60) and 5*1.20= ($6)
Now the fractions, 1/12 would equal 10 cents. 5/12 + 1/12= 6/12 which would also equal (60 cents). 3.60+6.00+.60= $10.20
Let's use mean to find this. Let's add 2.3 and 4 each twice, one number per year.
2.3+2.3+4+4=12.6
Now divide 12.6 by four since there are 4 numbers.
12.6/4=3.15.
Haylee's average GPA is 3.15.
Answer:
5y-16=3y+10
5y-3y=10+16
2y=26
y=26/2
y=13
5×13-15=49
3×13+10=49
the length of the legs are 49 each
Answer:
ED = 12 and FD = 24
Step-by-step explanation:
See the attached diagram.
The perpendicular distance between the three parallel lines are same i.e. AB = BC = 8
Therefore, the parallel lines will divide any transverse line ( say FD ) in 1 : 1 ratio i.e. will divide equally.
Therefore, FE = ED = 12 units.
Again, FD = FE + ED = 12 + 12 = 24 units. (Answer)
