Emilio and friends are in a submarine 500 feet below sea level. They continue to dive 35 feet each hour for 7 hours.

katovenus [111]

You would write the equation out as x=35x+500

You substitute x for 7 so it’s x= 35(7)+500

So the answer will be 745 dollars

Please help! This is due in less that 10 minutes! (Will mark Brainliest!)

Answer:

<em>Answer: a = - 12</em>

Step-by-step explanation:

We have here two equations, one 18x + 12y = 36, the other ax - 8y = - 24;

Now if we were to consider making these two equations have a common y co - efficient, we would multiply the top equation by 2, the bottom consecutively by - 3. This would make a standard 24y ;

2 * ( 18x + 12y = 36 ), ⇒ 36x + 24y = 72

+ - 3 * ( ax - 8y = - 24 ) + - 3ax + 24y = 72

As you can see, all terms are equivalent, besides that of the co - efficient of x. Knowing that, it would be ax must be multiplied by - 3 to receive 36x, as the bottom equation is multiplied by - 3, where all terms are equivalent to the top terms;

- 3 * ax ⇒ 36x, - 3 * - 12x = 36x,

<em>Answer: a = - 12</em>

the difference between two numbers is 9. the first number plus twice the other number is 27. find the two numbers

tatuchka [14]

So,

Let's translate this into mathematical form.

x - y = 9
x + 2y = 27

Elimination by Addition
Divide both sides of the second equation by 2
$\frac{1}{2}x + y = 13 \frac{1}{2}$

Add the two equations together
$\frac{3}{2} x = \frac{45}{2}$

Multiply both sides by $\frac{2}{3}$
$x = \frac{90}{6} \ or \ 15$

Substitute
15 - y = 9

Subtract 15 from both sides
-y = -6
y = 6

Substitute
15 - 6 = 9
9 = 9 This checks.

15 + 2(6) = 27

Distribute
15 + 12 = 27
27 = 27 This also checks.

S = {(15,6)}
