AysviL [449]

Answer:

The  graph of 3rd picture is correct Option.

Step-by-step explanation:

Let x =green and y = carrots

We make equations of the given sentences and then plot them to find the correct answer.

The equation for A salad made such that the difference between twice the ounces of greens and the ounces of carrots is at least 3 is

2x-y ≥ 3

The equation for the sum of the ounces of greens and twice the ounces of carrots is less than 4.

x+2y < 4

We plot both the equations and gain the graph.

The graph is attached in the figure.

The  graph of 3rd picture is correct Option.

Does anyone know the answer to this?? thank you! :)
Vsevolod [243]

Answer:

38+2x+125 = x+163

subtract x from both sides

38+x + 125 = 163

38+125 = 163

163+x = 163

subtract 163 from both sides

x=0

spin [16.1K]

Answer:

The decimal number is 0.964

Step-by-step explanation:

we have

9(\frac{1}{10})+ 6(\frac{1}{100})+4(\frac{1}{1,000})

step 1

Multiply each fraction by the whole number

(\frac{9}{10})+ (\frac{6}{100})+(\frac{4}{1,000})

step 2

Convert each fraction in a decimal number

Remember

Move the decimal point to the left as many places as there are zeros in the factor.

Move the decimal point one step to the left (10 has one zero).

Move the decimal point two steps to the left (100 has two zeros)

Move the decimal point three steps to the left (1000 has three zeros)

0.9+0.06+0.004

step 3

Adds the number

0.964
