Answer: they have
et n = number of nickels
Let d = number of dimes
given:
(1) +n+%2B+d+=+45+
(2) +5n+%2B+10d+=+360+
-------------------
Multiply both sides of (1) by 5
and subtract (1) from (2)
(2) +5n+%2B+10d+=+360+
(1) +-5n+-+5d+=+-225+
+5d+=+135+
+d+=+27+
and, since
(1) +n+%2B+d+=+45+
(1) +n+%2B+27+=+45+
(1) +n+=+45+-+27+
(1) +n+=+18+
She had 18 nickels and 27 dimes
check:
(2) +5%2A18+%2B+10%2A27+=+360+
(2) +90+%2B+270+=+360+
(2) +360+=+360+
Step-by-step explanation:
Answer:18 nickels 27 dimes

What is the answer to this problem? Abby had $6.00 to spend on a treat with his 3 friends. If he spends the same amount on his 3 friends, what is his maximum amount of money he can spend on each person?
Answer:
$2.00
Step-by-step explanation:
Abby had $6.00 to spend on a treat with his 3 friends.
We are told in the question that: If he spends the same amount on his 3 friends
Hence: the maximum amount of money he can spend on each person is calculated as:
$6.00/3 friends
= $2.00
Therefore, the maximum amount of money that he can spend on each friend is $2.00

Rona mixes 2 pounds of meat with some chopped vegetables to make a mixture. She divides the mixture into 4
portions. Each portion weighs 3 pounds. Which equation and solution shows the total amount of chopped vegetab
used in the mixture?
o 3 (2+1)= 3; v= 10 pounds of chopped vegetables
o 3 (2+v)= 3; v = 4
pounds of chopped vegetables
O 4(2+V)= 3; V = 1 pound of chopped vegetables
O 4(2+1) = 3; v = 5 pounds of chopped vegetables
Answer:
I think the answer is..... 4(2+v)=3; v=1 pound of chopped vegetables.

A savings account offers 0.7% interest compounded bimonthly. If $110 is deposited in this account, what will the balance be after 15 years?
Answer:
$111.15
Step-by-step explanation:
Using the formula for calculating compound interest
A = P(1+r/n)^nt
A = 110(1+0.007/(1/24))^15(1/24)
A = 110(1+0.0168)^0.625
A = 110(1.0168)^0.625
A = 110(1.010)
A = 111.15
Hence the balance after 15 years is $111.15

System of Linear Equations (Substitution Method)
Answer:
y= 6x + 5 (I dont know if that's what you are looking for but I'm pretty sure that's the correct answer )
Step-by-step explanation:
you have to get y on the other side by its self
6x - y = -5
subtract 6 x from both sides
-y = -6x - 5
divide by -1
y = 6x +5
A system of equations is shown below.
3x + 2 y = 12
y=x+1
Which y value represents the solution to this system of equations?

Find the value of A in each cases:
- cosA=√3/2
Answer:
A = [tex]\frac{5\pi }{6}[/tex]
Step-by-step explanation:
Given that Cos A = [tex]-\frac{\sqrt{3} }{2}[/tex]
cos A = [tex]cos (\pi -\frac{\pi }{6} )[/tex]
A = [tex]\pi - \frac{\pi }{6}[/tex]
A = [tex]\frac{5\pi }{6}[/tex]

C. These lines are perpendicular
Step-by-step explanation:
Answer:
C. the lines are perpendicular
Step-by-step explanation:
you can tell right away they're perpendicular because the slope gets flipped and changed the sign for in the second equation
2/3 going to -3/2 or vice versa means they are perpendicular
if they had the same slope they would have been parallel
