Answer:

z=2

Step-by-step explanation:

5/20=z/8

Rewrite the equation as z/8=5/20

z/8=5/20

Multiply both sides of the equation by 8.

8⋅z8=8⋅520

Simplify both sides of the equation.

z=2

Anna35 [415]

Step-by-step explanation:

2(heads) + 2(goats) = 140

Heads are given, so we get:

2(52) + 2(goats) = 140

104 + 2(goats) = 140

2(goats) = 36

goats = 18

Since we know the number of goats, we know the number of chickens.

34Chickens and 18 goats.

How can I graph 34+12d>100 on a number line?

marissa [1.9K]

Answer:

d> 5.5

The graph in the attached figure

Step-by-step explanation:

we have

$34+12d>100$

Solve the inequality for d

That means ---> isolate the variable d

Subtract 34 both sides

$12d>100-34\\12d> 66$

Divide by 12 both sides

$d>\frac{66}{12} \\d>5.5$

The solution is the interval (5.5,∞)

All real numbers greater than 5.5

In a number line the solution is the shaded area at right of d=5.5 (open circle)

The value of d=5.5 is not included in the solution
