Since the difference*4=36, the difference = 9
since the number-6= the difference, the number-6=9
Thus the number is 15

Hey, I need help BAD!! I am doing PEMDAS. 7+(5times6)45+9<br><br><br> Please help me!! Thanks!

Answer:1

<h2>1,366</h2>

Step-by-step explanation:

P - parenthsis

E - exponents

M - multiplication

D - division

A - addition

S - subtraction

<h3>STICK TO THE ORDER:</h3>

7 + 5 x (6 x 45) + 9 = 1,336 ( Not the pemdas order)

But,

<h3>7 + (5 x 6)45 + 9 = 1,366 is the correct order for using PEMDAS.</h3>

Write an equation of the line satisfying the given conditions. Through (2, -5), parallel to 5x 6y + 7

mojhsa [17]

We have to determine the equation of the line passing through the point (2,-5) and parallel to the line $5x = 6y+7$

When two lines are parallel, then the slopes of the two lines are equal.

Equation of line with point $(x_1, y_1)$ and slope 'm' is given by:

$(y-y_1) = m(x-x_1)$

Since, we have to determine the equation of a line with point (2,-5).

So, the equation of the line is : $(y-(-5)) = m(x-2)$

$y+5 = m(x-2)$

Since, the line is parallel to the line $5x = 6y+ 7$

So, $6y +7 = 5x$

$6y = 5x - 7$

$y = \frac{5}{6}x - \frac{7}{6}$

So, slope of the line 'm' is $\frac{5}{6}$ .

Therefore, the equation of the line is:

$(y+5) = \frac{5}{6}(x-2)$

$6y + 30 = 5x - 10$

$6y - 5x = -10-30$

$6y - 5x = -40$

Therefore, $6y - 5x = -40$ is the required equation of the line.

Matt needs to swim 8 meters in 25 seconds yo qualify as a state swimer. Which unit rate describes the speed Matt needs to swim

fiasKO [112]

Answer:

Option D, 0.32 meters per second

Step-by-step explanation:

<u>Step 1: Find the unit rate at which Matt needs to swim</u>

Make an equation to represent the scenario.

<em>25m = 8</em>

<u>Step 2: Solve for m by dividing both sides by 25</u>

25m / 25 = 8 / 25

<em>m = 0.32</em>

<u>Step 3: Check</u>

To check, you can multiply the number of second, 25, by the meters per second to see if you get the total meters, 8.

0.32 * 25

<em>8</em>

So, the answer is correct :)

<u><em>0.32 means that Matt needs to swim 0.32 meters per second to qualify as a state swimmer.</em></u>

Answer: Option D, 0.32 meters per second

ASAP 100 POINTS, WILL MARK BRAINLIEST, should be a whole number

rosijanka [135]

Answer:

$x=2.$

Step-by-step explanation:

$\text{Since Pythagoras Theorem, we have}\\10^2=x.(x+48)\\\Rightarrow x^2+48x=100\\\Rightarrow x^2+48x-100=0\\\Rightarrow x^2 -2x+50x-100=0\\\Rightarrow x.(x-2)+50.(x-2)=0\\\Rightarrow (x-2).(x+50)=0\\\Rightarrow x=2 \: \text{or} \: x=-50.\\\text{Since x is positive}\\\text{Therefore}, x=2.$
