Answer:

x = 0

y = -2

Step-by-step explanation:

The given system of equation are:

5x + y = -2

2x - 2y = 4

The problem here is to find x and y from the expression

5x + y = -2 ----- i

2x - 2y = 4 ---- ii

So;

i x 2 : 10x + 2y = -4 ---- iii

ii x 5 : 10x - 10y = 20 ----- iv

iii - iv; 12y = -24

y = -2

Now find x;

5x + y = -2

5x - 2 = -2

x = 0

A certain ferry moves up and down a river between Town A and

Blizzard [7]

Answer: 60 miles

Step-by-step explanation:

Given

It takes ferry 2 hours to travel to town A and only $1.5\ hr$ to travel back to town B.

Speed of current is $u=5\ mph$

Suppose the speed of the ferry is $v$ mph

Distance traveled in both the cases is same, but it took more time traveling to city A that is, ferry is moving upstream and downstream for returning time.

$\Rightarrow 2(v-5)=1.5(v+5)\\\Rightarrow 2v-10=1.5v+7.5\\\Rightarrow 0.5v=17.5\\\Rightarrow v=35\ mph$

Distance between the towns is $2\times (35-5)=60\ \text{miles}$

Answer:

The answer to your question is C. 3.2

Step-by-step explanation:

| 3.2 |

lines | | mean absolute value, and absolute value means the distance of a number to the origin (0,0) it does not matter the sign.

Then to answer your question just do not write the | | and consider it as a positive sign.

If your question had a negative number ex. | -3.2 | the answer would also be 3.2.

Write 25x10 the power of 6 in standard from

forsale [732]

Answer:

25 * 10^6

But 10^6 is the same as multiply 10 six times, that is, 10 * 10 * 10 * 10 * 10 * 10 * 10. The result is as simple as writing 1 and six zeros, that is, counting the number of zeros I can see. So, 10^6 = 1000000.

Now, 25 * 10^6 = 25 * 1000000

The final answer is 25000000
