For a snack, sameer ate a plum with 32 calories and several strawberries with 4 calories each. if the total number of calories in sameer's snack was 56, how many strawberries did he eat? 6 strawberries8 strawberries14 strawberries22 strawberries

6

Step-by-step explanation:

Given : The total number of calories in Sameer's snack = 56

Calories in plum = 32

Then the calories in strawberries =

The number of calories in each strawberry = 4

Then , the number of strawberries he ate =

Hence, he ate 6 strawberries in Sameer's snack.

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
