Answer:
40
Step-by-step explanation:
Ratio of cars to total:
32:80
so we can make another ratio with x
x:100
now make them fractions and cross-multiply
32/80 = x/100
32(100) = 80x
80x = 3200
x = 40
Answer:
12
Step-by-step explanation:
If Alicia has 2 pets Fatima has 4 since 2 x 2 = 4. Izzy has 3 times as many as Fatima then she has 12 since 3 × 4 = 12
Wait, what’s the question type it in the comments here and I’ll answer!!
Ok so, A + B = 2 x - 2
And A - B = 4 x- 8.
Solving: A = (2x-2+4x-8)/2 = (6x-10)/2= 3x-5
B = (2x-2-4x+8)/2= (-2x+6)/2= -x+3
Happy studying ^-^
Answer:
x = -9
Step-by-step explanation:
3^4х = 27^(x-3)
Replace 27 with 3^3
3^4х = 3^3^(x-3)
We know that a^b^c = a^ (b*c)
3^4х = 3^(3(x-3))
Since the bases are the same, the exponents are the same
4x = 3(x-3)
Distribute
4x =3x-9
Subtract 3x from each side
4x-3x = 3x-3x-9
x = -9
