Answer:

A. (5,2)

Step-by-step explanation:

If you go to solve the equation you would first try to get y by itself in the first equation and you would do that by subtracting x on both sides. Then you would have y=7-x and then you would plug the second equation in for the x and get the equation y=7-y-3 because you distribute the negative sign of the x to both the y and 3. Then you combine like terms and get y=4-y and then add the y to both sides and get 2y=4 and then divide both sides by 2 and get y=2. Then you plug in y in the first equation and get x+2=7. Then you subtract 2 from both sides and get x=5.

ZP bisects ∠OZQ so that ∠OZP = 8x – 9 and ∠PZQ = 5x + 18. Find the value of x, and the measure of each angle. You must show all

Assoli18 [71]

<span>x = 9 Since ZP bisects â OZQ, that means that the measurements for â OZP and â PZQ are the same. So create an equation with their respective values set to each other. 8x - 9 = 5x + 18 Now solve for x 8x - 9 = 5x + 18 Subtract 5x from both sides 3x - 9 = 18 Add 9 to both sides 3x = 27 Divide both sides by 3 x = 9</span>

In a game, a participant is given three attempts to hit a ball. On each try, she either scores a hit, H, or a miss, M. The game

Sidana [21]

Answer:

chancing for wining is 54%.

Step-by-step explanation:

possible outcomes can be given as

HHH *

HHM *

HMH

MHH *

HMM

MHM

MMH

MMM

Out of those, only 3 will have the participant win the game:

HHH, HHM, MHH.

Probability (HHH) + Probability (HHM) + Probability (MHH)

since attempts are independant.

Probability (HHH) = 0.9 *0.4 *0.9 = 0.324

Probability (HHM) = 0.9 *0.4 *0.3 = 0.108

Probability (MHH) = 0.3 *0.4 *0.9 = 0.108

Add them up and get = (0.324+ 0.108+0.108) = 0.54

hence, chancing for wining is 54%.

The scale On a map is 2 cm equals 15 miles is measures the distance to the next town at seven cm how many miles away is the next

Ghella [55]

Answer:

2cm = 15 mi

you have to figure out how far 7cm equals, so you would have:

6cm = 45 mi

that leaves 1 cm left, so if 2cm = 15 mi then 1 cm would equal 7.5 mi.

so your distance would be 45 mi + 7.5 mi = 52.5 mi to the next town.
