X/2 +3y = 6 . . . . . . . . starting point
x/2 = 6 -3y . . . . . . . . subtract terms that don't have x
x = 2(6 -3y) . . . . . . . . multiply by the inverse of the x-coefficient
x = 12 -6y . . . . . . . . . expand if you like

3y = 6 -x/2 . . . . . . . . subtract terms that don't have y
y = (6 -x/2)/3 . . . . . . . multiply by the inverse of the y-coefficient
y = 2 -x/6 . . . . . . . . . expand if you like

Answer:

  1. no parts have the same color (0)
  2. yellow, blue, red
  3. percentages can be written in several forms: fraction, decimal, for example. The sectors can also be identified by their angle measures.
  4. see attached

Step-by-step explanation:

1. The seven different sectors have seven different colors. No parts have the same color.

2. The attached table lists the sectors in decreasing order of size. The largest three are yellow, blue, red.

3. Percentages can be written a number of ways. They can be written as decimal numbers, or as fractions. In a pie chart, the sectors can also be given an angle measure.

4. Fraction equivalents of the percentages are shown in the attached.

5. Reduce fraction equivalents of the percentages are shown in the attached.

Please help I’m really confused. I will give BRAINLIEST!
stiv31 [10]

Answer:

t = 115

s = 60

g(x) = 10/23x - 10

Step-by-step explanation:

find s first since its easy (it goes up by 10's)

then take a pair from the table that corresponds such as 69 for x and 30 for g(x) and turn them into a fraction:

69/30

do the same for t:

t/50

equal 69/30 to t/50 and solve using cross multiplication:

69/30 = t/50 =  

30t = 3450

/30      /30

t = 115

honestly had a little hard time finding the equation but basically I simplified the fraction 30/69 to get 10/23 for slope and then I insert a corresponding x and y value into y= mx+b with the slope value to find b.

A shopper bought a 12-pound bag of oranges for 18.75. What is the unit price per ounce?
noname [10]

Answer:

About $0.10 per ounce

Step-by-step explanation:

12 pound costs $18.75. Lets find the cost per pound first:

Cost Per Pound = \frac{18.75}{12}=1.5625

We know, there are 16 ounces in 1 pound.

We know 1 pound costs 1.5625

To find cost per ounce, we have to divide this by 16.

So,

Cost Per Ounce = \frac{1.5625}{16}=0.097

Rounded to nearest cent, that would be 10 cents per ounce
