Ed has 30 sweets. The ratio of red sweets to yellow sweets is 2:3. How many red sweets does Ed have?

12

Step-by-step explanation:

total= 30

now,

let redsweets be 2x n yellow sweets be 3x

2x+3x=30

5x=30

x=6

now ,

red sweets= 2x=2×6=12 sweets.

b. x- 48 =120

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
