The two numbers in each column have to add to 23
So under 7 you write 16, above 4 you write 19, etc

The rule will say x + y = 23

Answer:

y = -16x + 23

Step-by-step explanation:

x = 7, 11, 14

y = 4, 18

x = 7, 19, 11 , 5, 14

23-7 = 16 and 23-11 = 12 and 23-14 = 9

y = 14, 4, 12, 18, 9

therefore

y = m x + c

y - 16 = -16 (x + x1)

y - 16 = -16x + 7)

y -16 + 16 = -16x + 7+16

y = -16x + 23

which proves y coordinate rests on 23 toys when x = 0.

Any number sentence or equation could be done, but this sentence is an equation of the line and represents.x + y on the graph.

PLEASE HELP ASAP!! an onion soup recipe calls for 3 2/3 cups of chopped onions. katrina has already chopped 1 1/3 cups of onions

ivanzaharov [21]

Answer:

$x+1\frac{1}{3}=3\frac{2}{3}$

Step-by-step explanation:

Let the number of cups of onions Katrina still needs to chop = x

She has already chopped the onions = $1\frac{1}{3}$ cups ≈ $\frac{4}{3}$ cups

So total amount of chopped onions = $(x+\frac{4}{3})$ cups

Since, onion soup recipe calls for the chopped onions = $3\frac{2}{3}$ cups ≈ $\frac{11}{3}$ cups

Therefore, equation which shows the number of cups of onions to be chopped more will be,

$x+1\frac{1}{3}=3\frac{2}{3}$

We further solve this equation for the value of x,

x = $\frac{11}{3}-\frac{4}{3}$

x = $\frac{(11-4)}{3}$

= $\frac{7}{3}$ cups

≈ $2\frac{1}{3}$ cups

What is 5/2 - blank = 1/3

sdas [7]

Step-by-step explanation:

taking that blank as x

5/2 -x = 1/3

the x will go to the right hand side of the equation which then would make it positive ( making x the subject) and 1/3 will come to the left hand side of the equation becoming -1/3

so the equation will become 5/2-1/3=x

solving the fraction then gives 13/6 or 2.17 as the value of x
