Answer:

111 cars

Step-by-step explanation:

30% of 78 is

78×30%=78×0.3=23.4

Cars needed to sell

78+23.4=111.4

Unless we can't have 0.4 of a car, we need to round that number, so 111.4≈111

State whether the equation is true, false or open? 4y+8=6y+3

g100num [7]

Answer:

Open

Explanation:

An open equation is an equation that has variables and CAN be solved

Example: 2x = 4 ......> can be solved giving ......> x = 2

A false equation is one where both sides can NEVER be equal

Example: 15 = 2(3) + 1 ..........> 15 can never be equal to 7

A true equation is one having no variables and both sides are ALWAYS equal

Example: 2(3) + 1 = 2(2) + 3 ........> 7 will always be equal to 7

Now, the given equation is:

4y + 8 = 6y + 3

Let's try to solve is:

4y + 8 = 6y + 3

6y - 4y = 8 - 3

2y = 5

y = 2.5

Therefore, the given equation contains a variable and can be solved which means that it is an open equation

Hope this helps :)

Consider exponential function h. h(x) = 3x + 4

GarryVolchara [31]

The function is always positive.

(0,5) is the y-intercept, since the graphed line never crosses the x axis, there is no x-intercept.

The function is positive and greater than 4 for all values of x

Not sure what the actual choices are on a couple of the questions. The choices would help answering.

Taylor saw an American alligator at a zoo that measured Ask Your Teacher feet long. The record length of an American alligator i

lianna [129]

Answer:

The record alligator is $6\frac{1}{4}$ feet longer than the alligator Taylor saw.

Step-by-step explanation:

Taylor saw an American alligator at a zoo that measured $12\frac{11}{12}$ feet long. The record length of an American alligator is $19\frac{1}{6}$ feet long. How much longer is the record alligator than the alligator Taylor saw?

For this first convert the mixed fraction into an improper fraction.

$12\frac{11}{12}=\frac{155}{12}$

$19\frac{1}{6}=\frac{115}{6}$

Now subtract $\frac{155}{12}$ from $\frac{115}{6}$ .

$\frac{115}{6}-\frac{155}{12}=\frac{75}{12}=6\frac{1}{4}$

Hence, the record alligator is $6\frac{1}{4}$ feet longer than the alligator Taylor saw.
