a. The player with the highest score sank 7 baskets and missed 3. What was the highest score?


b. The player with the lowest score sank 2 baskets and missed 8. What was the lowest score?


c. Write an expression using addition to find out what the score would be if a player sank 5 baskets and missed 5 baskets.

Answers

Answer/Step-by-step explanation:

A.   (7 x 10) = 70

      (3 x -15) = -45

      70 + -45 = 25

B.    (2 x 10) = 20

       (8 x -15) = -120

       20 + - 120 = - 100

C.     (5 x 10) + ( 5 x -15) or 5 x (10 + -15)

         5 x 10 = 50

         5 x -15 = -75

         50 + -75 = -25

What is linear equation in one variable?

A linear equation in one variable is an equation which has maximum of one variable of order 1. It is of the form  ax + b =0, where x is the variable.

Solving Linear Equation in one variable

For solving an equation having one variable, the following steps are followed:

Step1: Using LCM, clear the fractions if any.Step2: Simplify both sides of the equation.Step 3: Isolate the variable.

According to the given question

We have, a linear equation in variable r.

2r +7 =16

⇒ 2r + 7 -7 = 16 -7

⇒ 2r = 9

⇒ r  = 9/2

Hence, the value of r is 9/2 for the given linear equation 2r + 7 = 16.

Kay spends 250 min/wk exercising. Her ratio of time spent on aerobics to time spent on weight training is 3 to 2. How many minutes per week does she spend on aerobics? How many minutes per week does she spend on weight training?

Answers

Time spent on aerobics is 150 minutes per week and time spent on weight training is 100 minutes per week

Solution:

Given that,

Kay spends 250 min/wk exercising

Therefore,

Exercising = 250 minutes per week

Ratio of time spent on aerobics to time spent on weight training is 3 to 2

Aerobics : weight training = 3 : 2

Let the time spent on aerobics be 3x

Let the time spent on weight training be 2x

Thus,

3x + 2x = 250

5x = 250

x = 50

Thus,

Time spent on aerobics = 3x = 3(50) = 150

Time spent on weight training = 2x = 2(50) = 100

Thus, Time spent on aerobics is 150 minutes per week and time spent on weight training is 100 minutes per week

Step By Step?

Answers

Answer:

123.45 + 67.891 = 191.341

Step-by-step explanation:

I don't know really know how to explain but I'll try to. So since 123.45 is the larger decimal so you put it first then below it you put 67.891.(not that it is necessary)

Then add a zero to 124.45. Meaning it will be 123.450. (It is the same number, we just have to add a zero there.)

Add then just add like you normally do. Just try doing it and you'll see.
