Pemdas
parenthases (none)
exponents
multiplication so

exponents
c^0.5
so 0.5=1/2 and if you have
x^(z/t)= $\sqrt[t]{x^z}$ so

c^1/2= $\sqrt[2]{c^1} or \sqrt{c}$ so

multiplication
-9 times √c is the answer or more commonly written as
-9√c

The answer depends on whether you're looking for the x or the y. If y, the answers are the ones on the left, and the x on the right.

1) -4x + 3y ≤ 15 -4x + 3y ≤ 15
 +4x +4x -3y -3y

3y ≤ 4x + 15 -4x ≤ -3y + 15
 --- --------- ---- ------------
3 3 -4 -4

y ≤ 4/3x + 5 x ≥ 3/4y + 11

2) -6x - 4y < 12 -6x - 4y < 12
+6x +6x +4y +4y

-4y < 6x +12 -6x < 4y + 12
---- ---------- ---- -----------
-4 -4 -6 -6

y > -3/2 - 3 x > -2/3y - 2

During a road trip Tony , Tony drove one third the distance that Lana drove. Mark drives 15 more than Lana drove .The total dist

ale4655 [162]

Answer:

The distance drive by Lana = 201 miles

The distance drive by Mark = 216 miles

The distance drive by Tony = 67 miles

Step-by-step explanation:

Given as :

The total distance cover by Lana , Tony , Mark = 484 miles

Let The distance drove by Lana = L miles

The distance drove by Tony = T

The distance cover by Mark = M

So , L + T + M = 484 miles

Now, The distance of Tony = $\frac{1}{3}$ of Lana distance

Or, T = $\frac{1}{3}$ × L

And The distance of Mark = 15 + The distance of Lana

Or, M = 15 + L

Now.

L + $\frac{1}{3}$ × L + 15 + L = 484

Or, 2 L + $\frac{L}{3}$ = 484 - 15

Or, 2 L + $\frac{L}{3}$ = 469

Or, $\frac{7 L}{3}$ = 469

Or, 7 L = 469 × 3

∴ L = $\frac{1407}{7}$

I.e L = 201

The distance drive by Lana = 201 miles

The distance drive by Mark = 15 + L =15 + 201 = 216 miles

The distance drive by Tony = $\frac{1}{3}$ × 201 = 67 miles

Hence The distance drive by each person is

The distance drive by Lana = 201 miles

The distance drive by Mark = 216 miles

The distance drive by Tony = 67 miles Answer

Allisa [31]

Answer: 40%

Step-by-step explanation:

To write 8/20 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % . 8/20 * 100 = 0.4 * 100 = 40% And finally we have: 8/20 as a percent equals 40%
