Answer:

B

Step-by-step explanation:

7 times 1x equals 7x. Then 7 times 2= 14. Thirdly, 7x plus 3x equals 10x. Lastly, 14 -3 equals 11. So 10-+11 altogether

What is the solution to the system of equations represented by the two equations?
Iteru [2.4K]
If you would like to solve the following system of equations, you can do this like this:

y = - 2 * x + 7
y = 1/3 * x
____________
1/3 * x = - 2 * x + 7
1/3 * x + 2 * x = 7
1/3 * x + 6/3 * x = 7
7/3 * x = 7      /*3/7
x = 7 * 3 / 7
x = 3

y = 1/3 * x = 1/3 * 3 = 1

The correct result would be: x = 3 and y = 1.

What is the probability that a point chosen at random on the grid will lie in the shaded region?
Mashcka [7]

Given:

A grid with a shaded region.

To find:

The probability that a point chosen at random on the grid will lie in the shaded region.

Solution:

We have,

Total number of small boxes = 100

Number of blue boxes (shaded region) = 36

Now,

probability that a point chosen at random on the grid will lie in the shaded region is

\text{Probability}=\dfrac{\text{Number of blue boxes (shaded region)}}{\text{Total number of small boxes}}

\text{Probability}=\dfrac{36}{100}

To find the probability in percent, multiply it by 100.

\text{Probability}\%=\dfrac{36}{100}\times 100

\text{Probability}\%=36\%

Therefore, the correct option is A.
