Troy and Lisa were shopping for school supplies. Each purchased different quantities of the same notebook and thumb drive. Troy bought five notebooks and five thumb drives for $110. Lisa bought three notebooks and five thumb drives for $102. Find the cost of each notebook and each thumb drive.

Answer:

2/5

Step-by-step explanation:

Two divided by 5 is simply written as 2/5.

Hope I helped!

Answer:

- 1/4

Step-by-step explanation:

7a + 2 = 3a + 1

subtract the 1 from both sides

7a + 1 = 3a

subtract 7a from both sides

1 = - 4a

divide by - 4

A = - 1/4

Answer:

a= - 1/4

Step-by-step explanation:

Answer/Step-by-step explanation:

Given that a and b are two corresponding sides of two similar figures, it follows that the ratio of their areas = a²/b².

We would use the above knowledge to solve the questions given as follows:

✔️The first pair similar of shapes:

Missing area = x cm²

Therefore,

x/9 = 8²/4²

x/9 = 64/16

x/9 = 4

Cross multiply

x = 4 × 9

x = 36 cm²

✔️The second pair similar of shapes:

Missing area = x cm²

Therefore,

x/240 = 8²/32²

x/240 = 64/1,024

Cross multiply

x*1,024 = 64*240

x*1,024 = 15,360

Divide both sides by 1,024

x = 15,360/1,024

x = 15 cm²

✔️The third pair similar of shapes:

Missing area = x cm²

Therefore,

x/40 = 3²/2²

x/40 = 9/4

Cross multiply

x*4 = 9*40

x*4 = 360

Divide both sides by 4

x = 360/4

x = 90 cm²

Answer:

• 39, Obet is right

Step-by-step explanation:

• I guess the = should be ÷ or else it doesn't make sense.

Simplify in steps considering the hierarchy of operations:

• 3 + 6 × {(15 + 9) ÷ 3 - 2} =                  Parenthesis
• 3 + 6 × {24 ÷ 3 - 2} =                         Parenthesis, division
• 3 + 6 × {8 - 2} =                                 Parenthesis, subtraction
• 3 + 6 × 6 =                                         Multiplication
• 3 + 36 =                                             Addition
• 39

Answer:

22/24

Step-by-step explanation:

The inscribed angle theorem says that the angle formed by two intersecting chords of a circle (the angle A between the chords AC and AB in this case) has half the measure of the central angle subtended by the arc containing those chords (arc CB in this case). So
