Tanina needs to buy at least 3 pounds of bananas. if she buys a bunch of bananas that way 42 ounces will she have enough ? explain

No, there is not enough

Step-by-step explanation:

We can tell this because there are 16 ounces in a pound. So we divide the number of ounces she bought by 16 to see how many pounds she got.

42/16 = 2 5/8

Since 2 5/8 is less than 3, we know she does not have enough.

the barter

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
