1. Joy bought jewelry at a crafts fair. She bought a necklace for $8 and some bracelets for $5 each. She spent $23 in all. Write and solve equation
that can be used to find the number of bracelets she bought

5y + 8 < 23  and y < 3

2c - 3 = 9

Step-by-step explanation:

She bought a jewelry at a craft fair . The necklace is $8 and the bracelet is $5 each. Her total expenses is $23.

She bought a single necklace. The number of bracelet she bought is unknown but each of the bracelet she bought is $5 each. The number of bracelet she bought can be represented below.

Let

y = number of bracelet bought

Therefore, the cost of the total number of bracelet will be 5y

Recall the total expenses is $23

5y + 8 < 23  and y < 3

if you insert the value of y in the following inequalities the resulting value should be less than 23 so the value of y should be less than 3.

2. 2c - 3 = 9

50-60=10

step-by-step explanation:

m∠a is 90°

m∠b is 40°
