Write and solve a system of equation for each problem?
A jar contains nickels and dimes. There is a total of 200 coins in the jar and their value is $14.55. How many dimes are in the jar?
Plz show the steps
Answer:
There are total of 80 dimes in the jar cuz...
n + d = 200 = n = 200 - d
0.05n + 0.1d = $14.00
0.05(200 - d) + 0.1d = $14.00
10 - 0.05d + 0.1d = $14.00
10 + 0.05d = $14.00
-10 -10
0.05d = $4.00
0.05d / 0.05 = $4.00 / 0.05
d = 80

Write the equation of the line in slope-intercept form using y=mx+b
Answer:
y = -1/6x + 5
Step-by-step explanation:
Slope is -1/6 and y-intercept is 5
Answer:
y=[tex]\frac{-1}{6}[/tex]x+5
Step-by-step explanation:
y=mx+b
m= slope
b= y-intercept
-1/6 is the slope because it is the unknown variable
5 is the y-intercept because it hits a perfect point on the y-axis
to find the slope i used rise/run the rise is -1 and the run is 6
the rise is negative because it is going to the left and essentially on a full graph that would be negative
hopefully this helps :) have a nice day !!

Answer:
ddddddddddddc daf a reag ehh fdsh
Step-by-step explanation:
Answer: =7x−5
Step-by-step explanation: Hope this help :D
Let's simplify step-by-step.
12x−20−5(x−3)
Distribute:
=12x+−20+(−5)(x)+(−5)(−3)
=12x+−20+−5x+15
Combine Like Terms:
=12x+−20+−5x+15
=(12x+−5x)+(−20+15)
=7x+−5

One market sells a 3-kilogram bag of tortillas for 45 pesos, and the second market sells 2 kilograms of tortillas for 22 pesos.
Which unit price is lower? / Would I subtract 2 kilo from 22 pesos?
Answer:
The second market is cheaper
Step-by-step explanation:
For the first market:
If the 3Kg = 45 pesos
then 1Kg = 15 pesos because you divide it by 3
In the same way for the second market:
2Kg = 22pesos
so 1Kg is 11 pesos as you divide it by 2.
Therefore the second market is cheaper as the unit price is lower.
The table shows the monthly fees for the checking accounts at two banks. Which statement is best supported by the information in the table?
A. The fee at Bank Y will be more than the fee at Bank Z only when a customer’s balance is more than $500.
B. The fee at Bank Y will always be more than the fee at Bank Z.
C. The fee at Bank Y will always be less than the fee at Bank Z.
D. The fee at Bank Y will be more than the fee at Bank Z only when the checking account balance is less than $500.
Answer:
A. The fee at Bank Y will be more than the fee at Bank Z only when a customer’s balance is more than $500.
The statement best supported by the information in the table is A. The fee at Bank Y will be more than the fee at Bank Z only when a customer’s balance is more than $500.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100.
Percentage is usually denoted by the symbol '%'.
Given in the table that,
Monthly fee for bank Y = 1% of checking account balance
Monthly fee for bank Z = $5
Suppose checking account balance = $500
Then,
Monthly fee for bank Y = 1% × 500 = 5
So, when the customer’s balance is $500, then fee at Bank Y is same as that of bank Z.
So, when the customer’s balance is more than $500, then fee at Bank Y is more than that of bank Z.
Hence the option is A.

#1 rodney's error for
y=30x+10 is that he started off at 30 but he had to start off at 10 so it starts at (0,10) (1,40) (2,70) and keep going on by adding one to the x value and 30 to the y value
#2 rodneys error for
y=-1/2x+5 is that he went up by 1/2 instead of going down. it's a negative 1/2 so he had to go down
#3 Rodneys error for
y=x-2 is that he didn't start at (0.-2)

Marc mixes blue and yellow paint to make his favorite shade of green, which he'll use to paint his house. He has 14 cans of blue paint and 20 cans of yellow paint when he starts.
He wants the same green color every time he mixes, so the amounts of blue and yellow must always be proportional to the original mixture.
On day 1, he mixes 4 cans of blue and 6 cans of yellow.
On day 2, he mixes 6 cans of blue and 9 cans of yellow.
Fill in the blanks to find the highest number of cans of each color Marc can mix to make the same shade of green on day 3.
Day 3's mixture must use the same simplified ratio of blue to yellow as the other two days. What is the greatest number of cans of blue and yellow paint Marc can mix on day 3? Assume he mixes only whole cans of paint.

what is the volume of the figure below
Answer:
665 ft^3
Step-by-step explanation:
The formula to find the volume of pyramids is 1/3 x length x width x height. One way to solve this is by multiplying the length, width and height, and then dividing it by 3.
14 x 9.5 x 15 = 1995
1995 / 3 = 665
So the volume is 665 cubic feet
