Answer:
X=36
Step-by-step explanation:
Let x be the unknown number
Three quarters of a number =3x/4
Three was added =3x/4 +3
Final
3x/4 + 3= 30
Multiply through with 4
3x+ 12=120
3x=120-12
3x=108
X=108/3
X=36
Answer:
9
Step-by-step explanation:
Given data
Ride ticket= $2
Admission= $7
Amount= $25
We want to find the greatest number of rides
let the number of rides be x
The expression to describe how she spends the amount is given as
y=7+2x
for y= 25, let us find x
25= 7+2x
25-7= 2x
18=3x
x= 18/2
x= 9
Hence the number of rides is 9
Multiply the numerator and denominator by the same number.<span> Two fractions that are different but equivalent have, by definition, numerators and denominators that are multiples of each other. In other words, multiplying the numerator and denominator of a </span>fraction<span> by the same number will produce an equivalent fraction. Though the numbers in the new fraction will be different, the fractions will have the same value.</span><span>For instance, if we take the fraction 4/8 and multiply both the numerator and denominator by 2, we get (4×2)/(8×2) = 8/16. These two fractions are equivalent.(4×2)/(8×2) is essentially the same as 4/8 × 2/2 Remember that when multiplying two fractions, we multiply across, meaning numerator to numerator and denominator to denominator.Notice that 2/2 equals 1 when you carry out the division. Thus, it's easy to see why 4/8 and 8/16 are equivalent since multiplying 4/8 × (2/2) = 4/8 still. The same way it’s fair to say that 4/8 = 8/16.<span>Any given fraction has an infinite number of equivalent fractions. You can multiply the numerator and denominator by any whole number, no matter how large or small to obtain an equivalent fraction.</span></span>
Answer:
67.307
Step-by-step explanation:
30×25=750
100×80=8000
