From Denver yo Chicago =3in if the scale is 1in=300miles

1 answer:

5 0

Basically a proportion so it’d be 1in/300 mi = 3in/x mi
cross multiple that out and you get 300•3=x and then just solve for x. the answer should be 900 miles.

3. Which describes the steps that can be used to solve this problem?

vodka [1.7K]

C. is your answer!

To find the answer to this problem you must find how many ounces there are total in the first part of the problem...3 glasses and 5 oz. in each one (5*3)=15!

Then the extra two ounces you just add on to 15! 15+2=17 total ounces Brad poured!

Hope this helps! Would love brainliest;)

It's C because 1 and 5 are the same angles so they are parallel.

Solve<br> 5(2x-y) = 7x + 1 <br> 3(3x+y) = 5(x-y+12)<br> using the elimination method<br> thanks!

MaRussiya [10]

Answer:

{x = 7 , y = 4

Step-by-step explanation using elimination:

Solve the following system:

{5 (2 x - y) = 7 x + 1 | (equation 1)

{3 (3 x + y) = 5 (12 + x - y) | (equation 2)

Express the system in standard form:

{3 x - 5 y = 1 | (equation 1)

{4 x + 8 y = 60 | (equation 2)

Swap equation 1 with equation 2:

{4 x + 8 y = 60 | (equation 1)

{3 x - 5 y = 1 | (equation 2)

Subtract 3/4 × (equation 1) from equation 2:

{4 x + 8 y = 60 | (equation 1)

{0 x - 11 y = -44 | (equation 2)

Divide equation 1 by 4:

{x + 2 y = 15 | (equation 1)

{0 x - 11 y = -44 | (equation 2)

Divide equation 2 by -11:

{x + 2 y = 15 | (equation 1)

{0 x+y = 4 | (equation 2)

Subtract 2 × (equation 2) from equation 1:

{x+0 y = 7 | (equation 1)

{0 x+y = 4 | (equation 2)

Collect results:

Answer: {x = 7 , y = 4

The equation y minus 1 = negative 7 (x minus 3). is written in point-slope form. What is the y-intercept of the line?

Tresset [83]

Answer:

(0, 22)

Step-by-step explanation:

So you have the equation:

$y-1=-7(x-3)$

So first let's define what the "y-intercept" is. The y-intercept, of a line is like the name implies, when the line intercepts or "passes" the y-axis. And if you were to take any point on the y-axis, the y-value may vary, but there is one value that doesn't change, and that's the x-value. the x-value is always going to be zero, no matter where you are on the y-axis. So to find the y-intercept simple plug 0 in as x. This gives you the equation:

$y-1 = -7(0-3)$

$y-1 = -7(-3)$

$y-1=21$

$y=22$

So the y-intercept is at (0, 22)

Chris jogged 1 3 of a mile to his friends house in 1 12 of an hour. Compute the unit rate from the complex fraction 1 3 1 12 mil

olga2289 [7]

The unit rate from the complex fraction ¹/₃ ÷ ¹/₁₂ is 4 miles per hour

<h3>Further explanation</h3>

Order of Operations in Mathematics follow this following rule :

Parentheses
Exponents
Multiplication and Division
Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.
