Solve elimination 5x+y=9 10x-7y=-18
k0ka [10]
<h2>(1, 4)</h2><h2 />

To solve this system by addition, notice that if we add these two equations together, neither one of our variables will cancel out.

In this situation, we need to set things up so that when we do add our two equations together, one of the variables will cancel out.

Notice that we have a 10x in our second equation. if we had a -10x in our first equation, then the x's would cancel out.

To create a -10x, we can multiply the top equation by -2 to get a -10x.

From there, rewriting our equation gives us -10x - 2y = -18.

Now the x's cancel. Just add the equations together

now to get the two-step equation -9y = -36.

Solving from here, <em>y = 4</em>.

Now plug y into either one of the equations

to find that x =1.

So our solution is (1,4).

kompoz [17]

Answer:

The answer is B : 6

Step-by-step explanation:

2.50k means 2.50 multiplied by a number and the inequality means 20 is less than 2.50k + 5.50.    2.50 multiplied by 6 equals 15 and 15 plus 5.50 is 20.50 which is greater than 20.

If x 60 and 30 find the unknown sizes of angle​
yaroslaw [1]

Answer:

A special right triangle is a right triangle having angles of 30, 60, 90, or 45, 45, 90. Knowledge of the ratio of the length of sides of a special right triangle enables us to solve for any missing part of the triangle. The ratio of the side lengths of a special right triangle with angles of 30, 60, 90 is 1:sqrt(3):2, while the ratio of the side lengths of a special right triangle with angles of 45, 45, 90 is 1:1:sqrt(2).

A jar contains 14 nickels, 10 dimes, 6 quarters, and 22 pennies. A coin is chosen at random from the jar. What is the probabilit
gulaghasi [49]
In order to determine the probability that the coin chosen is a dime, determine first the total number of sample coins. In this problem, there are 52 coins all in all. Next, divide the number of dimes in the sample with the total number of coins. This gives us 10/52. Simplifying the fraction further yields to 5/26. Thus, the probability that the coin chosen is dime is 5/26. The answer is letter c.
