Here are some solutions: (there are actually an infinite amount of them)

x = 0 , y = 7

x = 1 , y = 8

x = 2 , y = 9

x = 3 , y = 10

x = 4 , y = 11

x = 42 , y = 49

x = pi , y = pi + 7

(a)

we are given

the price of apple suddenly up by $0.75

Let's assume original price be 'p'

we are given

Sam bought 3 pounds of apple at the new price total is $5.88

so, new price = old price +0.75

price of 3 apples $=3(p+0.75)$

we are given that price is 5.88

so, we get equation as

$5.88=3(p+0.75)$ .......Answer

(b)

Since, original price is p

so, we have to solve for p

$5.88=3p+2.25$

$5.88-2.25=3p+2.25-2.25$

$3.63=3p$

$p=1.21$

so, original price is $1.21 per pound........Answer

Sophia uses 18 beads to make a necklace. Three sixths of the beads are purple. How many beads are purple?

joja [24]

Answer:

9 beads are purple

Step-by-step explanation:

we know that

To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple

$18(\frac{3}{6})=9\ beads$

therefore

9 beads are purple

Another way to solve the problem is convert the fraction in percentage

we have

$\frac{3}{6}=\frac{1}{2}=0.50*100=50\%$

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple
