First write the inequality: 15

4.75x +3.50
Then to solve, first subtract 3.50 from both sides to get:
11.50

4.75x
Then divide by 4.75 to get 2.42, and since you can't buy .42 of a bag of fruit, you round down. So your final answer would be 2 bags of fruit.
Answer:
12 cm x 15 cm
Step-by-step explanation:
if the picture frame thickness is x,
then the frame dimension would be (8+2x) cm by (11+2x) cm
area is (8+2x)(11+2x)=180
solve for x, x= 2, -23/2
x is thickness, so should be >0, so x=2
frame dimension: 12 x 16
You didn't provide answer choices, but since 0.4=4/10 is rational, adding any irrational value to it will produce and irrational sum.
An irrational number is any number which can not be expressed as a fraction of two integers.
