Answers

Answer 1

Answer:

-11/3

-1/3

The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

Justify each step used to simplify the expression. 1. 3x+ 2y− 2x+ 2 = 3x− 2x+ 2y+ 2

Answers

Step-by-step explanation:

We have to simplify the given expression:

1. 3x+2y-2x+23x+2y−2x+2

Combining the like terms,we get the second step as

2. (3x-2x)+(2y)+(2)(3x−2x)+(2y)+(2)

Now, taking 'x' common from the first two terms, we get third step as:

3. (3-2)x+2y+2(3−2)x+2y+2

Now, simplifying the expressions among the like terms, we get fourth step as:

4. x+2y+2x+2y+2

alice average mark for 4 science exams is 68%. Can alice score enough marks In a fifth exam so that her average Mark increases to 75% give reasons

Answers

Answer:

it is impossible she gets a 75% because as far as we know she can only score a maximum of 100 and she needs a 103

Step-by-step explanation:

We're going to assume that alice got a 68 on all 4 of her science exams

which means that so far we have[tex]\frac{68+68+68+68}{4}=68[/tex]

And we need to find out if she can get a 75 which means that we have the following

[tex]\frac{68+68+68+68+x}{5}=75[/tex]

Solve for x

272+x=375

x= 103

Therefore (unless there is extra credit available in the exam) it is impossible she gets a 75% because as far as we know she can only score a maximum of 100

Write the equation for the model below. Then solve for x.

Just think of it as normal subtraction. They both have the same denominators all you need to do is subtract. 11/12-7/12 is 4/12 if you simplify which just means to find the number that both 4 and 12 can go into equally the simplified answer would be 1/3. You just need to divide 4 by both the top and the bottom (numerator and denominator).

Your first bungee jump is 50 1/6 feet higher than your second jump. Your first jump reaches −200 2/5 feet. Select the equation you can use to find the height h (in feet) of your second jump. Then find the height of your second jump.

Answers

Answer:

h= −250 17/30

Step-by-step explanation:

Let's solve your equation step-by-step.

−200 2/5 −50 1/6 = h

Step 1: Simplify both sides of the equation.

−7517/30 = h

Step 2: Flip the equation.

h = −7517/30

Answers

Answer:

1646/1

Step-by-step explanation:

To write 1646 as a fraction you have to write 1646 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

1646 = 1646/1 = 16460/10

technically it should be 1646/1 because it’s a whole number, and whole numbers are always over the number one when you write them as fractions.
