X+(x+1)+(x+2)+(x+3)=156
4x+6=156
4x=150
x=37.5 (not an integer)
If x=37 you get 37+38+39+40=154 and if x=38 you get 38+39+40+41=158[/tex]
Answer:
A and C
Step-by-step explanation:
Using the fact that = i , then
=
= ×
= ± 4 × i
= 4i → A
= - 4i → C
To answer this item, we are first to calculate the values of the length of this particular metal rod that is 0.045 cm less than the given,
Lower limit = 20.5 cm - 0.045 cm = 20.455 cm
Also, we calculate for the upper limit by adding 0.045 cm to the given length.
Upper limit = 20.5 cm + 0.045 cm = 20.545 cm
Thus, the answer to this item is D.
You multiple straight across then simplify your answer !
Answer:
a) $7.50
b) 10 miles
Step-by-step explanation:
a)
y=mx+b
y=$29.50
x=8
m=$2.75
b=unknown
29.50=2.75(8)+b
29.50-22=22-22+b
7.50=b
Check:
2.75(8)+7.50=29.50
b)
y=$35
x=unknown
m=2.75
b=7.50
35-7.50=2.75x+7.50-7.50
27.5/2.75=2.75/2.75x
10=x
