152.5 is 250% of the number, 61
Answer:
3 : (1/2) =
Step-by-step explanation:
Divide: 3 :
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of is ) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
In words - three divided by one half = six.
7/20 = 0.35 = 35%=500x.35 =170 men
40%=.40x500 =200 women
200+170=370
500-370
130 children
Let x equal the # of coach tickets
Let y equal the # of first class tickets
x + y = 16
260x + 970y = 10,550
Solve and state the answer. Use the substitution method to solve this system. Solve the first equation for x.
x + y = 16
x = 16 - y
Now substitute the resulting expression into the other equation and solve for y.
260( 16 - y ) + 970y = 10,550
4160 - 260y + 970y = 10,550
Combine like terms
4160 + 710y = 10,550
Subtract 4160 from both sides
710y = 6390
divide by 710
y = 9
Substitute the value of y into the equation that we solved for x, x=17−y.
x = 17 - 9
x = 8
Therefore the answer is, 8 coach tickets and 9 first class tickets.
$600x06x3= $108.00- the interest and with the $600 it would be $708
