Solve the equation.<br><br> 2 ( 4z - 1) = 3(z+2)<br><br> Z=
sveta [45]

Answer:

z = \frac{8}{5}

Step-by-step explanation:

Calculate for the value of z :

2(4z - 1) = 3(z + 2)

-Use <u>Distributive Property</u> on both left and right:

2(4z - 1) = 3(z + 2)

8z - 2 = 3z + 6

-Take 3z and subtract 8z :

8z - 3z - 2 = 3z - 3z + 6

5z - 2 = 6

-Add 2 to both sides:

5z - 2 + 2 = 6 + 2

5z = 8

-Take 5z and divide on both sides:

\frac{5z}{5} = \frac{8}{5}

z = \frac{8}{5}

Therefore, the value of z is \frac{8}{5}.

diego is collecting pennies and estimated that he has 120 pennies. he counted them and has 80 pennies. what is diego's percentag
Bezzdna [24]

Answer:

50%

Step-by-step explanation:

The percent error is equal to the absolute value, difference of the measured value or your experimental value minus the actual value divided by the actual value times 100%;

Here we have;

Measured Valued = 120 pennies

Actual Value = 80 pennies

% error = \frac{|Measured - Actual|}{Actual} * 100

% error = \frac{|120 - 80|}{80} * 100

% error = \frac{|40|}{80} * 100

% error = \frac{40}{80} * 100

% error = 50%

So, 50% is the percent error for Diego
