9 lead cubes of side 3 cm could be made from a lead cube of side 27 cm.
This is because,
27/3= 9
There are 16 ounces in a pound, so 8 ounces would be half a pound (0.5 lb)
Answer:
x=1
Step-by-step explanation:
log_4(x + 3) + log_4x = 1
We know that loga(b) + loga(c) = loga(bc)
log_4(x + 3)x = 1
Raise each side to the base of 4
4^log_4(x + 3)x = 4^1
(x+3)x = 4
x^2 +3x = 4
Subtract 4 from each side
x^2 +3x -4 = 0
Factor
(x+4) (x-1) =0
Using the zero product property
x= -4 x=1
But x cannot be negative since logs cannot be negative
x=1
Question 11
x+x+1/2x+1/2x=360
x+x+2/2x+=360
x+x+x=360
3x=360
x=120
Then substitute 120 in the place of x
x1=120
x2=120
1/2(120)=60
1/2(120)=60
To check your answer you can add 60+60+120+120 the should be equal to 360
Question 12
x+x+(x-45)+(x-45)+(x-45)=540
x+x+x-45+x-45+x-45=540
5x-135=540
5x=540+135
5x=675
x=675/5
x=135
Then substitute 135 in the place of x
x1=135
x2=135
135-45=90
135-45=90
135-45=90
To check your answer you can add 135+135+90+90-90 the should be equal to 540
