Answer:
The value of y is 1
Step-by-step explanation:
4 - (y - 3) = 3(y + 1) - 4(1 - y)
4 - y + 3 = 3y + 3 - 4 + 4y
7 - y = 7y - 1
7 + 1 = 7y + y
8y = 8
y = 1
Thus, The value of y is 1

Hector took out a small loan of $900 for 18 months. The simple interest rate on the loan was 10.5%. How much will he pay in interest on the loan?
Answer:
The answer would be $1.89 in interest.
Step-by-step explanation:
First, change 10.5% into a decimal. To do this, you divide 10.5÷100. This equals 0.105
next, you multiply 0.105 with 12 (12 months in a year)
This equals 1.26
But, Hector still has 6 months left he has to pay for.
So, one way you can do this is divide 1.26 by 2, which equals 0.63.
THEN, you add 0.63 with 1.26, giving you the answer, 1.89
So, the answer for this equation would be 1.89.

You have 100 coins worth $6.95. All of the coins are nickels and dimes. How many nickels and how many dimes do you have? Write a system that represents the situation. Estimate the solution using a graphing calculator.
Answer:
61 Nickels and 39 Dimes
Step-by-step explanation:
you have $3 and 5 cents in nickels and 3$ and 90 cents in Dimes
it all equals 100 coins all together
The number of dimes is 39 dimes
The number of nickels 61 nickels
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of dimes be = x
Let the number of nickels be = y
So , total number of coins = 100
x + y = 100 be equation (1)
And , the total amount = $ 6.95
The cost of one dime = $ 0.10
The cost of one nickel = $ 0.05
So , total cost = 0.10x + 0.05y = 6.95 be equation (2)
Now , on simplifying equation (1) and equation (2) , we get
x + y = 100
10x + 5y = 695 be equation (3)
Divide equation (3) by 5 , we get
2x + y = 139 be equation (4)
Now , Subtracting equation (1) from equation (4) , we get
x = 39
Therefore , the number of dimes is 39 dimes
Substituting the value of x in equation (1) , we get
x + y = 100
y + 39 = 100
Subtract 39 on both sides of the equation , we get
y = 61
Therefore , the number of nickels is 61 nickels
Hence ,
The number of dimes is 39 dimes
The number of nickels 61 nickels

Write the following comparison as a ratio reduced to lowest terms.
21 nickels to 43 dimes
Answer:
As coins, they are already in their simplest ratio, since 25 and 38 don't have any common factor to divide by. (1 doesn't really count...)
As money, you need to multiply the 25 nickels x 5 cents per nickel, which gives you 125 cents,
and 38 dimes x 10 cents per dime, which gives you 380 cents.
So your new ratio is 125:380, which you can simplify by dividing each by 5, which gives you
25:76
SO, as money the ratio in simplest terms is 25:76. As numbers of coins, it's 25:38
If you think about it, it makes sense because:
10 cents is twice as much as 5 cents, and
76 cents is twice as much as 38 cents.
Hope this helps!

Ten cents cost twice as much as five cents, and 38 cents are equivalent to twice as much as 76 cents.
Explain about the Ratio?
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value
Since there is no
to divide 25 by and 38 by, they are already in their most basic ratio as coins. (1 is hardly significant...)
To convert the 25 nickels to money, multiply them by the nickel's value, which comes to 125 cents.
and 38 dimes multiplied by 10 cents each, giving you 380 cents.
By dividing each by 5, you can simplify your new ratio of 125:380 and get
25:76
Therefore, the ratio is 25:76 expressed simply as money. It is 25:38 in monetary terms.
It makes sense if you think about it since
Ten cents are twice as expensive as five cents, and
38 cents is double what 76 cents

Venetta buys 2 pounds of pistachios and 3 pounds of almonds. The pistachios cost $4 more per pound than the almonds. She pays a total of $48. Which of the following are true? Select all that apply.
A. One pound of pistachios plus 1 pound of almonds cost $20.
B. The pistachios cost twice as much per pound as the almonds.
C. Reducing the number of pounds of almonds by 1 results in a total cost of $40.
D. The cost a, in dollars, of 1 pound of almonds is modeled by 2(a – 4) + 3a = 48.
E. The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48.
The options that are true include:
A. One pound of pistachios plus 1 pound of almonds cost $20.
C. Reducing the number of pounds of almonds by 1 results in a total cost of $40.
E. The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48.
Cost of almond = a
Cost of pistachios = a + 4
Therefore, based on the information given, the equation to solve the question will be:
2(a + 4) + 3a = 48
Collect like terms
2a + 8 + 3a = 48
5a = 48 - 8
5a = 40
a = 40/5
a = 8
Almonds cost $8
Pistachios cost $12
In conclusion, the correct options are A, C, and E.
