Miss Smith needed 2 1/5 pounds of corn Mesa in order to make tamales. when she went to the grocery store she found a package of 1 3/8 pounds. what fraction of a pound does she still need?

Answers

Answer 1
Answer:

For this case we must do a subtraction, for this we convert the mixed numbers given in fractions:

2 \frac {1} {5} = \frac {10 + 1} {5} = \frac {11} {5}\n1 \frac {3} {8} = \frac {8 + 3} {8} = \frac {11} {8}

We subtract to know what fraction of mass of corn needs Miss Smith.

\frac {11} {5} - \frac {11} {8} = \frac {8 * 11-5 * 11} {40} = \frac {88-55} {40} = \frac {33} { 40}

Thus, it lacks\frac {33} {40} of pounds of corn dough.

Answer:

\frac {33} {40}

Tyler simplified the expression. His procedure is shown below.

Answers

Answer:

B:Both powers should be in the denominator with positive exponents.

Step-by-step explanation:

We are given that Tyler simplified an expression

x^(-3)y^(-9)

We have to find an error which Tyler makes in her simplification

Step 1: x^(-3)y^(-9)

Step 2:(1)/(x^3)\cdot y^(-9)

Step 3:(1)/(x^3y^9)

Hence, Tyler's error is both exponents should be denominator with positive exponents.

Answer:B:Both powers should be in the denominator with positive exponents.

Answer:

Step-by-step explanation:

                                                        1

Tyler correctly rewrote x^(-3) as ------- , but

                                                       x³

                                                       1

he incorrectly wrote y^(-9) as   ---------

                                                    y^(-9)

Both x^9 and y^9 should be in the denominator.  This corresponds to the 2nd given possible answer.

Find the missing coefficient. -___________ y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0

Answers

Answer:

Missing Coefficient is -8

Step-by-step explanation:

We are given, _y² - [ -5y - y( -7y -9) ] - [ -y(15y + 4) ] = 0

We have to find missing value.

let missing value be a

ay² - [ -5y - y( -7y - 9) ] - [ -y(15y + 4) ] = 0

ay² - [ -5y + 7y² + 9y ] - [ -15y² - 4y ] = 0

ay² - [ 7y² + 4y ] + 15y² + 4y = 0

ay² - 7y² - 4y + 15y² + 4y = 0

ay² - 7y² + 15y² + 4y - 4y = 0

( a - 7 + 15 )y² = 0

RHS can be written as

( a - 7 + 15 )y² = 0.y²

Now comparing coefficient of both sides we get,

a - 7 + 15 = 0

a + 8 = 0

a = -8

Therefore, Missing Coefficient is -8

  y = 0

Answers

Answer:

x = -5

Step-by-step explanation:

-9(x+3) = -9x-27

Add 27 onto both sides and get -9x = 45

Divide -9 on both sides and you'll see that x = -5 because 45/-9

Answer: X=-5        distribute the -9 to x and 3 move the 3 over to the 18 and - 18-3 then dived -9x/15
