Percent is parts out of 100 so x%=x/100
25%=25/100=1/4
wwhat number is 1/4 of 64
x=1/4 of 64
'of' translates to multiply
x=1/4 times 64
x=16
the number is 16
2x +4)° 2x-9)°= 4x 2 +8x−9=3
Pull out like factors :
2x + 4 = 2 • (x + 2) (4 • (x + 2) • x) - 9
4x • (x + 2) - 9
Factoring 4x2+8x-9
The first term is, 4x2 its coefficient is 4 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 4 • -9 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is 8 .
-36 + 1 = -35
-18 + 2 = -16
-12 + 3 = -9
-9 + 4 = -5
-6 + 6 = 0
-4 + 9 = 5
-3 + 12 = 9
-2 + 18 = 16
-1 + 36 = 35
x=3
Answer:
Out of mean, median, mode, and range, the answer to this question is mode. If an outlier is removed, mode will not change. Hope this helps!
Answer:
Cost for 1 burger = 5 $
Amount spent by Janet = 25$
Amount spent by John = 25$
Explanation:
Let the cost for burger be p.
Janet got three burgers and left a $10 tip
Amount spent by Janet = 3 p + 10
John bought 4 burgers, but only left a $5 tip
Amount spent by John = 4 p + 5
Both paid the same amount.
So, we have 3 p + 10 = 4 p + 5
=> p = 5 $
So, cost for 1 burger = 5 $
Amount spent by Janet = 3 x 5 + 10 = 25$
Amount spent by John = 4 x 5 + 5 = 25$
