Answer:
x=-3
y=3
Step-by-step explanation:
-27=-9x-18y equation 1
-5y-10x-15=0 equation 2
using equation 2 we have:
-10x -15 =5y
y= -2x -3 equation 3
using equation 3 in equation 1 we have:
-27=-9x-18(-2x -3)
-27= -9x +36x +54
-27-54 =27x
-81 = 27x
so we have:
x= -81/27
x=-3
y= -2(-3) -3
y= 6-3
y = 3
Answer:(1,-4)
Step-by-step explanation:
<span> the number of points scored by the Storm in the first half was equal to the number of points scored by the Chargers in the second half of the game
S1 = C2
</span><span>In the first half the Storm scored one-fourth the total points scored in the game
S1 = 1/4 (T</span><span>)
</span><span>During the second half the Chargers scored 16 points less than one-third the points scored in the game.
C2 = 1/3(T</span><span>) - 16
Solving for
S1
C2
and
T
T is the total points of the game</span><span />
I'm not quite sure what this question means, but d = rt is a formula used to calculate the distance. the variables here are d for distance, r for rate, and t for time. if you need to solve it for t:
d = rt ... divide both sides by the rate (r)
(d/r) = t ... is your result
Hello there i hope you are having a great day :) Your question: Suppose 21% of people own a dog. If you pick two people at random, then what is the probability that they both own a dog?
1) 21% own a dog so you would do 21/100 = 0.21 this would equal the first person now the second person you would do 21/100 = 0.21
2) now you would multiply it so 0.21 x 0.21 = 0.0441 the that would be your answer.
Hopefully that helps you ❤
