Peter has $12 in nickels and quarters. Altogether, he has 72 coins. Use the variables n and q to write and solve a system of equations to determine how many of each coin she has.
Step-by-step explanation:
n= nickels
q= quarters
Create a system of equations
n + q =72 number of coins
0.05n + 0.25q = 12 amount in money
solve by elimination ( anything would be fine)
n + q = 72
4( 0.05n + 0.25q = 12)
n+ q = 72
-
0.2n + q = 48
0.8n = 24
n= 30
now use substitution to find how many quarters she has
30 + q = 72
q = 42
He has 30 nickels and 42 quarters

Answer:
x=22 y= 46
Step-by-step explanation:
2-24 2-48
Answer:
Equations are :---
[tex]3x - 2y = 24............... (i) \\ x + 2y = 48..................(ii)[/tex]
By adding the both equations we get,
[tex](3x - 2y) + (x + 2y) = 24 + 48 \\ 4x = 72 \\ x = \frac{72}{4} \\ \boxed{ x = 18} \\ [/tex]
Putting the value of x in equation (ii) we get
[tex]18 + 2y = 48 \\ 2y = 48 - 18 \\ 2y = 30 \\ y = \frac{30}{2} \\ \boxed{y = 15}[/tex]
Therefore, x=18 and y=15 is the right answer.Find square roots of

If a triangle has lengths of 3ft and 54ft, what are all the possible lengths for the third side?
51ft
53ft
55ft
57ft
58ft
Answer:
53, 55
Step-by-step explanation:
by the triangular inequality theorem, in a triangle.. sum of two sides is always greater than the third side.
3+54=57 ... exclude 57 and 58
3+51=54 ... exclude 51

what is z=xy solve for y
Z = xy
To solve for y, divide both sides by x.
Y = z/x
Answer:
[tex]\underline{z = xy} \\ \boxed{ y = \frac{z}{x} }[/tex]

if you put money into a savings account that earns $84.00 over seven years at a rte of 3%, how much money did you put into the account?
Answer:
Step-by-step explanation:
To solve this, we would use the formula for calculating simple interest which is:
Interest = PRT
Then, we will slot in the values given which will be:
84 = P × 3% × 7
84 = P × 0.03 × 7
84 = 0.21P
P = 84/0.21
P = $400
The Principal is $400

The number of parking spots (y) in the local town (x) years from now can be modeled by the equation below. How many spots are being added every year? y=200x+10000
Answer:
200
Step-by-step explanation:
Given that :
Slope intercept equation :
y=200x+10000
The number of spots being added per year is the value of slope in the equation ;
The general form of a slope intercept equation is :
y = mx + c
Where m = slope
Comparing the equation given to the general formula ; m corresponds to 200 ; hence number of spots added per year = 200

. Trent’s mom said he could spend no more than
$12 for rides at the carnival. If the rides cost
$0.75 each, how many rides can he go on?
thanks for the help..
Answer:
16 rides
Step-by-step explanation:
If he has $12 in total and each ride costs 75 cents, you can divide 12 by .75 to find how many rides he can go on.
12/0.75 = 16

Andre and Elena are each saving money Andre starts with $100 in his savings account and adds five dollars per week Elena starts with $10 in her savings account and add 20 each week after four weeks who has more money in her savings account
Answer: Andre
Step-by-step explanation: coz I juss know..
Answer:
Andre
Step-by-step explanation:
This situation can be modeled with the equations:
A = 100 + 5w
E = 10 + 20w
Let w represent the number of weeks that have passed since they have started saving money. Andre(A) has saved $5 per week and Elena(E) has saved $20 per week. Substituting 4 into the equation (because 4 is the number of weeks that have passed so far) and evaluating we come to the realization that Andre still has more money than Elena because he now has $120 and Elena has $90.
Select the FALSE statement
A) Dilations either increase or decrease the lengths of line segments.
B) Dilations increase angle measures.
C) A dilated triangle is similar to the original triangle.
D) Dilations are a type of transformation
9514 1404 393
Answer:
B) Dilations increase angle measures.
Step-by-step explanation:
Dilations have no effect on angle measures, but they uniformly change the size and spacing of line segments. They are a non-rigid transformation that leaves geometric figures similar to the original.
The false statement is B.

Which of the following sunds does not result in an answer of -5?
1. (-7) + (+2)
2. (-11) + (+6)
3. (-9) - (-4)
4. (-8) - (+3)
Answer:
4. (-8) - (+3)
Step-by-step explanation:
This answer does not result in an answer of -5
This subtracts -3 from -8, which gives you the answer of -11.
So, this answer is correct because it is the one that doesn't result in -5.
Answer:
Problem #4
Step-by-step explanation:
Some things to remember when doing problems like are
Double negative = positive
Double positive = positive
Negative & positive = negative
1. (-7) + (+2) 2. (-11) + (+6) 3. (-9) - (-4) 4. (-8) - (+3)
-7 + 2 -11 + 6 -9 + 4 -8 - 3
-5 -5 -5 -11

Which point on the unit circle corresponds to −4π3?

(12, −3√2)
(3√2, −12)
Answer:
A is the answer (− 12,3√2)
cos(6x-12) = sin(8x-10)
Subtract sin (8x − 10) from both sides of the equation.
cos (6x − 12) − sin (8x − 10) = 0
Answer:
It doesn't exist
Step-by-step explanation:
since :
cos (90° – x) = sin x
cos(x) = sin(pi/2 - x)
then
cos(6x-12) =! sin(8x-10)
since (8x-10) =! (pi/2- 6+12)
then this identity of cos(6x-12) = sin(8x-10) doesn't exist
