Answer:

The constant of proportionality is the ratio between two directly proportional quantities. In our tomato example, that ratio is $3.00/2, which equals $1.50. Two quantities are directly proportional when they increase and decrease at the same rate.

cranberry juice cost $6.30 per quart and apple juice cost $3.60 per quart Terence wants to know how many quarts q of cranberry j

Gekata [30.6K]

Note: "total" is from adding the first and last columns (middle column should be provided because it is a rate which cannot be added).

Amount x Cost = Amount x Cost

Cranberry: q $6.30 $6.30q

Apple: 4 $3.60 $3.60(4) = $14.40

Total: 4 + q $4.50 = $6.30q + $14.40

$4.50(4 + q) = $6.30q + $14.40

$18.00 + $4.50q = $6.30q + $14.40

$3.60 = $1.80q

2 = q

Since you didn't provide the equation options, hopefully you can use the solution to help you decide which option to choose.

The rules which tell which caculations are done before others in an expression

julia-pushkina [17]

This rule is known as PEMDAS

In an algebraic equation follow PEMDAS

P= first calculate anything with parantheses

E= then calculate anything with exponents

M= calculate any multiplication

D= calculate any division

A= calculate any addition

S= calculate any subtraction

you must do these in that order

hope this helps:)

Answer:

a battery costs £0.43

Step-by-step explanation:

Set up an equation

11b+b+4.84=10

Subtract 4.84 from both sides

12b+4.84=10

-4.84=-4.84

12b=5.16

Divide 12 on both sides

b=5.16/12

b=0.43

Rewrite the following in ascending order. 9/25, 2/5, 14/-75, -19/10, 8/15

madam [21]

Step-by-step explanation:

Given numbers are 9/25 ,2/5, 14/-75, -19/10, 8/15

The denominators = 25 , 5, 75, 10, 15

LCM of the denominators = 150

9/25 = (9/25)×(6/6) = 54/150

2/5 = (2/5)×(30/30) = 60/150

14/-75 =(-14/75)×(2/2) = -28/150

-19/10 = (-19/10)×(15/15) = -285/150

8/15 = (8/15)×(10/10) = 80/150

Ascending order of the numbers

= -285/150, -28/150, 54/150, 60/150, 80/150

-19/10, 14/-75, 9/25, 2/5, 8/15
