Cross multiply.
75 / x = 25 / 35
25x = 35(75)
25x = 2625
/25 /25
x = 105
Therefore 105 students liked skating.
Proof:
105 + 35 = 140.
140 * 0.75 = 105
140 * 0.25 = 35
140 (total) split into quarters.
35 + 35 + 35 + 35 = 140
35 + 35 + 35 = 105 (3 quarters liked)
35 = 35 (1 quarter disliked)
Answer:
Step-by-step explanation:
There is a missing operator in the second equation.
If the equation is 4x - 8y = 4, then the system is dependent. The second equation is a non-zero multiple of the first.
Answer:
$720
Step-by-step explanation:
$20000 - 100%
$x. - 2.5%
x=(20000*2.5)/100=500
20000+500=$20500 in one year (Mark)
20000 - 100
x. - 6.1
x= (20000*6.1)/100 = 1220
20000+1220= $21220 (Walter)
21220-20500= $720 more (Walter will have after 1 year)
15ft because 12x.25=3 so 3ft is 25% of the 12ft, add the 3+12=15
Answer:
18 and 6
Step-by-step explanation:
Rn = 6 Ratio numerator
Rd = 2 Ratio Denominator
Rs = Rn + Rd
Rs = 6 + 2
Rs = 8
Ratio Sum
a = 24 Amount to Divide
M = a ÷ Rs
M = 24 ÷ 8
M = 3 Multiplier Ratio Division Calculation
Rr = Rn × M : Rd × M
Rr = 6 × 3 : 2 × 3
Rr = 18 : 6
