Seems to be an arythmetic sequence
Sn=[n(a1+an)]/2
where
Sn means sum of all terms up the nth term
n=number of terms
a1=first term
an=nth term
so from 86 to the 22th term is from a1 to a22
find teh sequence
miknus 7 each time
an=a1+d(n-1)
an=87-7(n-1)
find 22n term
a22=87-7(22-1)
a22=87-7(21)
a22=87-147
a22=-60
S22=[22(87-60)]/2
S22=[22(27)]/2
S22=594/2
S22=297
the sum is 297
Answer:
y= -4/3x +8
Step-by-step explanation:
well first you got to simply for equation
4x +3y = 24
so you subtract 4x to both sides and that gives you : 3y= -4y +24
then you divide everything by 3
and that leaves you with : y= -4/3x +8
and the graph just put a dot on 8 on the y axis then go down -4 and left 3
your welcome!!!!!!!!1
8 x 64 = (8 x 60) + (8 x 4)=

Answer:
Step-by-step explanation:
The word problem describes two relationships between the numbers of cookies baked. When b and f represent the numbers of cookies baked by Bill and Felicia, respectively, those relationships are ...
- Bill bakes 3 times as many cookies as Felicia. (b = 3f)
- Felicia bakes 24 fewer cookies than Bill. (f = b-24)
