Answer:

Step-by-step explanation:

total money = $2.25 = 225 cents

types of denomination in coins or cents are dimes and nickels

dime = 10 cents , nickel = 5 cents

twice of dimes to nickels

let no of dimes = x and no of nickels = y

our equation

10x + 5y = 225

x = 2y

10(2y) + 5y = 225

20y +5y = 225

25 y = 225

y=9

x =2y 2x9 = 18

so the number of dimes = 18 and nickels = 9

cross verification:

10x18 + 5x9 = 180 +45 = 225

Amber bought three 8 pound bags of dog food at $2.25 per pound, two 4 pound bags of cat food at $1.75 per pound, and three 1/4 p

Romashka-Z-Leto [24]

Answer:

$Total = \$73$

Step-by-step explanation:

Given

$Three\ 8lb = \$2.25/lb$ --- Dog Food

$Two\ 4lb = \$1.75/lb$ ----- Cat Food

$Three\ \frac{1}{4}lb = \$6.98$ -------- Fish Food

Required

Determine the amount spent

For Dog Food

$1\ lb = \$2.25$

Amber bought 8lb.

So, that is:

$8 * 1\ lb = \$2.25 * 8$

$8\ lb = \$18$

He bought 3 of those;

$Cost = 3 * \$18$

$Cost = \$54$

For Cat Food

$1\ lb = \$1.75$

Amber bought 4lb

So, that is:

$4 * 1\ lb = 4 * \$1.75$

$4\ lb = \$7$

He bought 2 of those;

$Cost =2 * \$7$

$Cost =\$14$

For Fish Food

$1\ lb = \$6.98$

Amber bought 1/4lb

So, that is:

$\frac{1}{4} * 1\ lb = \$6.98 * \frac{1}{4}$

$\frac{1}{4}\ lb = \$1.745$

He bought 3 of those;

$Cost = 3 * \$1.745$

$Cost = \$5.235$

Total amount spent is:

$Total = \$54 + \$14 + \$5.235$

$Total = \$73.235$

$Total = \$73$ (approximated)

Which function below is the inverse of f(x)= 7x-1/2

Keith_Richards [23]

Answer: $f^{-1}(x)=\frac{x}{7}+\frac{1}{14}$

Step-by-step explanation:

If we have y=7x-1/2, the inverse is where we solve for x instead of y.

We can isolate x to get 7x=y+1/2, then divide by 7 to get x=y/7+1/14.

Therefore, $f^{-1}(x)=\frac{x}{7}+\frac{1}{14}$ .

For what value of the variable the value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x)?

iragen [17]

For x=2, the value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x)

Step-by-step explanation:

We have to convert the given statement in mathematical or algebraic form to get the value of x for which the given condition is true.

So,

The problem can be written as:

$4(5x-8) = 2(4-x)+4$

Applying distributive property

$20x-32 = 8-2x+4\\20x-32 = 12-2x\\$

Adding 32 on both sides

$20x-32+32 = 12-2x+32\\20x = 44-2x$

Adding 2x on both sides

$20x+2x = 44-2x+2x\\22x=44$

Dividing both sides by 22

$\frac{22x}{22} = \frac{44}{22}\\x = 2$

Hence,

For x=2, the value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x)

There are two numbers that is equal to 52.2 is less than.whats is the answer

sergeinik [125]

Set up an system:
x+y=52
x=y-2

Substitute in:
(y-2)+y=52
2y-2=52
2y=54
y=27

27-2=25

The answers are 27 and 25
