What are the values of X and Z.

stiv31 [10]

Answer:

x = 12, z = 86

Step-by-step explanation:

Two angles are called supplementary when their measures add up to 180 degrees.

(12x -58 + 13x - 62 ) = 180°

12 x + 13x -58 - 62 = 180°

25x - 120 = 180

25x = 180 + 120

x = 300/ 25

x = 12

----------------------------------------------------------------------------------

(z° + 13x - 62) = 180

(z° + 13(12) - 62 )= 180

(z° + 156 - 62 )= 180

(z° + 94 ) = 180

z° = 180 - 94

z = 86

Natalie added 20 pieces of candy to a bowl. Two days later, half of the candy in the bowl is gone. If there are 14 pieces left i

Salsk061 [2.6K]

Answer:

8 pieces of candy

Step-by-step explanation:

Take the original amount of candy in the bowl to be $x$ .

It says that 20 pieces of candy were added, therefore there are $x+20$ pieces of candy in the bowl.

Half of the candy is gone, therefore $\frac{x+20}{2}$ pieces of candy are left in the bowl.

After half of the candy is gone, there are 14 pieces left, so we can say that $\frac{x+20}{2} =14$

Solve for $x$ :

$x+20 = 28$

$x=8$

Suppose Lin labels the books at a constant speed of s books per minute. There can be several equations written that represent th

Alla [95]

Answer:

$S = \frac{b}{m}$

Step-by-step explanation:

Given

$Speed = s$

Required

Determine the expression for s

The speed is calculated as:

$Speed = \frac{Number\ of\ books}{Time}$

Substitute S for speed

$S= \frac{Number\ of\ books}{Time}$

Let the number of books be b and the time be m.

The expression becomes

$S = \frac{b}{m}$

Hence, the expression for the scenario is:

$S = \frac{b}{m}$
