Ariana grande spent $25 to buy 9 flowers for her mother. she bought roses which cost $3 and daisies which cost $2. look at the real world problem below and give the two equations needed to solve the system as well as the answer to the system. there will be 3 total answers.

let x be the number of roses  and y the number of daisies

x+y= 9 ( flowers)

3*x will be the cost of the roses

2*y will be the cost of daisies

then 3x+2y= 25 $ ( the cost of the 9 flowers)

therefore the 2 equations

x+y= 9

3*x+ 2*y= 25

solution of the two equations:

we multiply the 1st equation by 2

2x+ 2y= 18

3x+2*y= 25

2nd equation minus 1st equation  we will have:

x= 7 therefore y=2

Step-by-step explanation:

3r+2d=25

r+d=9

r=7 d=2

Step-by-step explanation:

use second equation and solve for d then

3r+2(9-r)=25

3r+18-2r=25

r=25-18

r=7

if r+d=9 and r=7 THEN d=2

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
