Let's use synth. div. It's so much faster in cases such as this one.
Use k = 3 as your divisor. Then:
________________
3 / 3 -4 -3 14
9 15 36
-------------------------
3 5 12 50 <= the remainder is 50.
N=number of nickles
d=number of dimes
n is 2 times d
n=2d
total money is 1.20
convert to cens
120 cetns
5n+10d=120
n=2d
5(2d)+10d=120
10d+10d=120
20d=120
divide both sides by 120
d=6
6 dimes is answer
answer is A, 6 dimes
Answer:
b is moving the fastest
Step-by-step explanation:
c looks like its closer and a looks like its faster but b has both so b is the fastest to get there
The unknown number expressed as a mixed fraction is 11 19/20
Let the unknown number be "x"
The sum of the number and 1.75 is expressed as x + 1.75
Half the sum of a number and 1.75 is 1/2(x+1.75)
Equating the result to -5.1 wil give:
1/2(x+1.75) = -5.1
Solve the resulting equation
x + 1.75 = 2(-5.1)
x + 1.75 = -10.2
x = -10.2 - 1.75
x = 11.95
x = 1195/100
x = 11 95/100
Hence the unknown number expressed as a mixed fraction is 11 19/20

Answer:
She needs the starting amount of money to create an equation.
Step-by-step explanation:
The formula that she can use when she has the starting amount or the y-intercept is this one: f(t)=P(1+b)^t.
t=time
b=percent
P=starting value
The formula with the information given is: f(6)=P(1+3.75)^6
Hope this helps!
If not, I am sorry.
