3x2-11x+10
No gcf so multiply first and last numbers together.
30- find two numbers that add/subtract to the number in then middle and multiply to be 30
Answer: (x-6)(x-5)
w/4 = 43
Multiply by 4 for both sides
w/4(4)= 43(4)
Cross out 4 and 4 , divide by 4
w= 172
Answer: 172
Answer:
It's the second option x = (3y - 11) / 5.
Step-by-step explanation:
3/5 = x+1/y-2
Cross multiplying:
3(y - 2) = 5(x + 1)
3y - 6 = 5x + 5
5x = 3y - 6 - 5
5x = 3y - 11
x = (3y - 11) / 5.
Everyday the number is tripled by 3 and x represents the number of days, which we don’t know, so it would be 3x.
He started with 24.
So the equation is:
24+(3x)
EXPLANATION
3x3 is 27 27x3 is 81 therefore 81x=243
