Answer:
x=0 y=2
Step-by-step explanation:
2x+3y=6 .... 1
-5x+2y=4 .... 2
Multiply 5 with equation 1 and multiply 2 with equation 2
Then we get
10x+15y=30
-10x+4y=8
-10x and +10x get canceled so 19y=38
y=38/19=2
substitute y value in equation 1 or 2 and find the value to get x

Pls help with this question
Answer:
it would be A
Step-by-step explanation:
the "<" (less sign) would mean B is less than A which is less than D which is less than C. if it is asking to put in the order which is greater than, there would need to be a ">" (greater sign). since there are no greater than signs, the process is flipped to be D is less than C which is less than A which is less than B meaning B is the greatest increasing likelihood, hope this helps :)
Answer:
(A) because it is more likely to draw a red or black card from a deck. Since the is letter d all the other choices don't have that so A is most likely the answer.

Based on this triangle, what statement about x is true?
A. x = 33 because 180−147=33
B. x = 62 because 147−85=62 and 85 + 62 = 147
C.x = 95 because 180−85=95 and 85 + 95 = 180
D.x = 118 because 180 − 147 + 85 = 33 + 85 = 118

A cell phone battery with 22% charge takes 176 minutes to run out. How long will a fully charge battery last?
Answer:
800
Step-by-step explanation:
176 divided by 22=8
8x100= 800
It will take 13.33 hours to battery run out.
What is unit rate?A unit rate means a rate for one of something.
Given that, A cell phone battery with 22% charge takes 176 minutes to run out.
In 22% → 176 minutes
In 1% → 176/22 = 8 minutes
In 100% → 8x100 = 800 minutes
800 minutes = 800/60 = 13.33 hours.
Hence, the battery will work for 13.33 hours when charged 100%
