Step-by-step explanation:
1.5 dollars a shirt
-(4/5)*(3/7)*(15/16)*(-14/9) [two negatives make one positive]
=(4*3*15*14)/(5*7*16*9) [simplify 4/16]
=(3*15*14)/(5*7*4*9)
=(3*3*14)/(7*4*9)
=(14)/(7*4)
=(2)/(4)
=1/2
Answer:
D
You multiply 4 by 7 then you get 28
Subsitution is subsituting
y=3x-2
y=-x+6
subsitute 3x-2 for y in second equation
3x-2=-x+6
add x to both sides
4x-2=6
add 2 to both sides
4x=8
divide both sides by 4
x=2
subsitute
y=-x+6
y=-2+6
y=4
x=2
y=4
Answer:
The given sequence is Algebraic (Arithmetic) with common difference is -9.
Step-by-step explanation:
The given sequence is Arithmetic Sequence.
Arithmetic Sequence is a sequence in which every two neighbor digits have equal distances.
Geometric Sequence is the sequence in which every digit is the same multiplier of its previous digit.
The given sequence is: 81, 72, 63, 54,...
Here, First term(a) = 81, Second term(b) = 72
Common difference (d) = b - a = 72 - 81 = -9
Hence, Common difference is -9.
