4x + 100 > 7x

100 > 3x i moved all the x's over to one side

100/3 > x

or just

x > 100/3

so they need to sell more than 33.33333... pizzas

No one makes a 1.3333... pizza as far as I know, so your answer might be 34.

A tree DOUBLES in height each year until it reached its maximum height over the course of 10 years. How many years did it take f
RideAnS [48]

Answer:

9 years

the tree doubles in height

we can make a model

1 x 2 = 2

2 x 2 = 4

4 x 2 = 8

8 x 2 = 16

16 x 2 = 32

32 x 2 = 64

64 x 2 = 128

128 x 2 = 256

256 x 2 = 512

512 x 2 = 1024

Let's say 1024 is the maximum height

half the maximum height is 1024 x 0.5 = 512 so it will take 9 years because it reached 512 on the 9th year

Which is the quotient if 3/5 and 1/10?
AlladinOne [14]

Answer:

6

Step-by-step explanation:

We have two fractions and are asked to find the answer if they both are divided.

3/5 and 1/10.

When we divide fractions, we need to follow KCF

KEEP - Keep the fractions

CHANGE - Change the division sign to a multiplication sign

FLIP - Flip the second fraction

Follow :

KEEP :

3/5 / 1/10

CHANGE :

3/5 * 1/10

FLIP :

3/5 * 10/1

Now we need to multiply, which is simple because it's multiplying across :

\frac{3*10}{5*1}

30/5

Simplify by dividing the numerator and denominator by 5 :

\frac{30/5}{5/5} = \frac{6}{1}

Divide the numerator by denominator :

\frac{6}{1} = 6

Which of the followingis multiplicative of -a? (-1/a a 1 1/a)​
Elodia [21]

Given:

The given value is -a.

To find:

The multiplicative inverse of -a.

Solution:

We know that y is the multiplicative interval of x if xy=1.

Let x be the multiplicative inverse of the given value -a. Then,

(-a)\times x=1

Divide both sides by -a.

x=\dfrac{1}{-a}

x=-\dfrac{1}{a}

Therefore, the multiplicative inverse of -a is -\dfrac{1}{a}. Hence the correct option is A.
