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
