I need the answers ?
Veseljchak [2.6K]

Answer:

HI=1/2*EF

17-3x=1/2*-9x+37

2(17-3x)=-9x+37

34-6x=-9x+37

-6x+9x=37-34

3x=3

x=3/3

x=1

now substitute the value of HI

17-3x

=17-3*1

=17-3

=14

Step-by-step explanation:

Note :HI=1/2*EF because the straight line joining the mid points of two sides of a triangle is parallel to the third side and equal to half of it.

Nimfa-mama [501]
Sample space of two fair fifty sided dice = 50^2 = 2500
Probability of rolling a double = 50/2500 = 1/50
Probability of not rolling a double = 1 - 1/50 = 49/50

Each unit on the grid stands for one miles determine two ways to calculate the distance from josie's house to annies
Novosadov [1.4K]
I encountered this problem before but it had an accompanying image and list of answer choices.

I'll attach the image and include the list of options. 

Each unit on the grid stands for one mile. Determine two ways to calculate the distance from Josie's house to Annie's house.
A) Distance Formula and Slope Formula
B) Midpoint Formula and Slope Formula
C) Distance Formula and Midpoint Formula
<span>D) Distance Formula and Pythagorean Theorem
</span>
My answer is: D.) Distance formula and Pythagorean Theorem.

When looking at the image, I can visualize a right triangle. I'll simply get the measure of the long and short legs and solve for the hypotenuse. 
Since the distance formula is derived from the Pythagorean theorem, it can be used to determine the distance from Josie's house to Annie's house.
