Answer:ito po hehe. Pakicorrect na Lang po pag mali
Step-by-step explanation:
X=10
-8-x=-3(2x-4)+3x
-8-x=-6x+12+3x
-8-x=-3x+12
-x+3x=12+8
2x=20
x=10
You can check your solution by inputting 10 in all the x’s and solving it:)
60 minute equal and hour so 60minutes
Answer:
Careful with blank 2! 6 - y would actually give 4. Y-6 would give -4.
Step-by-step explanation:
This transformation is a translation.
Answer:
The correct answer is d. (40, 60)
Step-by-step explanation:
To start using the linear combination method, you need a variable that will cancel out. To get this, we will multiply the second equation by -20 and then add together.
x + y = 100
-1.4x - y = -116
-----------------
-0.4x = -16
x = 40
Now that we have the value of x, we plug into one of the original equations to find y.
x + y = 100
40 + y = 100
y = 60
