Answer 1

Answer:

23a) x=-y+9/2

23b) x=1/2 y+3/2

Step-by-step explanation:

23a:

Let's solve for x.

2x+2y=9

Step 1: Add -2y to both sides.

2x+2y+−2y=9+−2y

2x=−2y+9

Step 2: Divide both sides by 2.

2x/2 = -2y+9/2

x = -y+9/2

23b:

Let's solve for x.

2x−y=3

Step 1: Add y to both sides.

2x−y+y=3+y

2x=y+3

Step 2: Divide both sides by 2.

2x/2=y+3/2

x = 1/2 y+3/2

A recipe for banana oat muffins calls for 3/4 cups of oats. You need to triple the recipe to make enough for your whole family. How much oats do you need?

Answers

Answer: 2 and 1/4 cups of oats (9/4 cups of oats)

Step-by-step explanation:

We know that, for the recipe, we need 3/4 cups of oats.

Now, you want to triple the recipe (then you need to use 3 times more ingredients).

This means that, if for the recipe you needed 3/4 cups of oats, when we triple that we have:

3*(3/4 cups) = 9/4 cups

This means that you need to use 9/4 cups of oats.

And we could also write this as:

9/4 cups = 8/4 cups + 1/4 cups = 2 + 1/4 cups of oats.

DUE IN 5 MINUTES MATH QUESTION ​

Answers

Answer:

x= -10

Step-by-step explanation:

So because the angle 55 is part of the same line as one of the unknown angles you can do 180-55 to find that first angle at the top, which is 125.

Next add all three angles (125 + x + 35 + x + 40)=180

Combine the x values to get 2x and subtract the three values from 180

Then 2x= -20, x should be equal to -10

You can plug x back into the values and check your work by adding all the values again, making it all equal to 180 degrees again

You and your friend participate in a charity run. For every mile run, $2 is donated to the charity. You run 4 miles and your friend runs 3 miles. How much money, in dollars, do you and your friend raise for the charity?

Answers

Answer:

$14

Step-by-step explanation:

Multiply each mile run by the amount of money for each mile. In this case, you run 4 miles and get $2 for each mile, so that's $8 for you. Your friend runs 3 miles, so that's another $6. Adding $8 plus $6 = $14.

You and your friend raised together 14 dollars for the charity by running.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, You and your friend participate in a charity run. For every mile run, $2 is donated to the charity.

Also given that You run 4 miles and your friend runs 3 miles.

Therefore, The amount in dollars you and your friend raised for the charity

is (2×4) + (2×3) dollars.

= 8 + 6 dollars.

= 14 dollars.

So, Both of them together raised 14 dollars for the charity.

Step-by-step explanation:

Line a

y = 5x - 6, it has slope of 5

Line b

x + 5y = 5

Rewrite in slope-intercept form to find its slope:

5y = -x + 5y = -1/5x + 1It has slope of -1/5

Lines have different slopes: 5 and -1/5, therefore are not parallel

Answer:

The answer to the question provided is False.

Step-by-step explanation:

‣We are going to have to find the value of y for line b.

‣We are going to solve its equation.

[tex]x + 5y = 5 \\ \frac{- x \: \: \: \: \: = - x}{ \frac{5y}{5} = \frac{ - x + 5}{5} } \\ y = - \frac{1}{5} x+ 1[/tex]

‣So we have:

[tex]y = 5x - 6 \\ and \\ y = - \frac{1}{5} x + 1[/tex]

‣Remember that a slope is parallel to another slope if it has the same slope.

‣A slope is perpendicular to another slope if it has a negative reciprocal.

‣The slopes we have don't have the same slope, but they are perpendicular.

Answer:

B

Step-by-step explanation:

Please answer this questions step by step​

Answers

Answer:

(a) When a = 4 and b = -5,  a² + b² - a·b = 61

(b) When a = 4 and b = -5,  a³·b + a·b² = -220

(c)  [tex]When \ a = 4 \ and \ b = -5, \ \dfrac{a - b}{a + b} + a -b = 0[/tex]

(d) When a = 4 and b = -5, (a + b)² - (a - b)² = 82

Step-by-step explanation:

The question relates to evaluation of expressions, given the values of the variables, "a" and "b"

Where;

a = 4 and b = -5

(a) For a² + b² - a·b, we have;

a² + b² - a·b = 4² + (-5)² - 4 × (-5) = 16 + 25 + 20 = 41 + 20 = 61

(b) For a³·b + a·b² we have;

a³·b + a·b² = 4³·(-5) + 4·(-5)² = 64 × (-5) + 4 × 25 = -320 + 100 = -220

(c) For [tex]\dfrac{a - b}{a + b} + a -b[/tex], we have;

[tex]\dfrac{a - b}{a + b} + a -b = \dfrac{4 - (-5)}{4 + (-5)} + 4 - (-5) = \dfrac{4 + 5}{4 -5} + 4 + 5= \dfrac{9}{-1} + 4 + 5 = -9 + 4 + 5 = 0[/tex]

[tex]\therefore when \ a = 4 \ and \ b = -5, \ \dfrac{a - b}{a + b} + a -b = 0[/tex]

(d) For (a + b)² - (a - b)² we have;

(a + b)² - (a - b)² = (4 + (-5))² - (4 - (-5))² = (4 - 5)² - (4 + 5)² = (-1)² - 9² = 1 + 81 = 82

When a = 4 and b = -5, (a + b)² - (a - b)² = 82

Jade has $60. She wants to buy some movies that cost $11 each. Jade wants to have at least $20 remaining.



Which of the following inequalities correctly represents the scenario?

Answers

Answer:

60-11x < 20

Step-by-step explanation:

Let's first set out all the information we know.

Jade has only $60, so we cannot go above the amount she has.Each movie costs $11She wants at LEAST $20 remaining  

So, the first thing that will be in the inequality would be $60. Since you are wasting money, you have to subtract.

The thing that will be subtracted more than once is $11, so it will have the variable "x" added to it.

What we have so far is:

60-11x

Because this is an inequality, we will have a less than sign.

After that, we can conclude that $20 will come next because that is at the end of the problem.

So, the answer is:

60-11x < 20
