Can you work these out? 0.6x100 0.15x100 3.7x100 0.8x100 0.07x100

Monica [59]

Step-by-step explanation:

$0.6 \times 100 = 60 \\ 0.15 \times 100 = 15 \\ 3.7 \times 100 = 370 \\ 0.8 \times 100 = 80 \\ 0.07 \times 100 = 7$

What is the value of z in the equation 2(4z − 3 − 1) = 166 − 46?

shepuryov [24]

Refine $2(4z-3-1)$

$= 2(4z-4)$

Refine : $166 - 16 = 120$

therefore:

$2(z-4) = 120$

Divide both sides by 2 :

$\frac{2(z-4)}{2} = \frac{120}{2}$

$4z-4 = 60$

add 4 to both sides:

$4z-4+4 = 60+4$

$4z = 64$

Divide both sides by 4 :

$\frac{4z}{4} = \frac{64}{4}$

$z = 16$

hope this helps!
