Step-by-step explanation:
6(-11.5) looks like 6*-11.5 to me which is -69.
Answer:
y= -8x + 150
x = -0.125y + 18.75
Step-by-step explanation:
<u>y explanation:</u>
16x+2y=300
Add -16x to both sides: 16x+2y+(-)16x = 300 + (-)16x - this becomes:
2y = -16x+300
Now divide both sides by 2: 2y/2 = (-16x+300)/2 - this becomes:
-8x + 150
So...y= -8x+150
<u>x explanation:</u>
16x+2y = 300
Add -2y to both sides: 16x+2y+(-)2y = 300+(-)2y - this becomes:
16x = -2y+300
Now divide both sides by 16: 16x/16 = (-2y+300)/16 - this becomes:
-1/8y + 75/4...you can simplify this to: -0.125y + 18.75
So...x = -0.125y + 18.75
I hope this helps :)
The triangle is 4 times bigger so multiply 25 by 4 that will give you 100 =6x + 28
subtract 28 from both sides then divide 6 by the answer you get after subtracting.
x = 12
6 times 12 equals 72. 72 plus 28 equals 100.
