The decimal -2.97 is the solution to which subtraction problem?
-6.1 - 3.13
-6.1 - (-31.3)
-0.61 - (-3.13)
-6.1 - (-3.13)
-6.1- 3.13 -6.1 - (-3.13) -0.61 - (3.13) -6.1 - (3.13)

Answers

Answer:

Option 4: -6.1 - (-3.13)

Step-by-step explanation:

Let's solve each option individually to see if  -2.97 fits as the solution:

-6.1 - 3.13 = -9.23

-6.1 - (-31.3) = 25.2

-0.61 - (-3.13) = 2.52

-6.1 - (-3.13) =  -2.97

As you can see, -2.97 is the answer to Option 4.

So, the decimal -2.97 is the solution to the subtraction problem in Option 4.

a pile of 40 coins consists of nickels and dimes. the total value of coins is $2.7 find the number of each type of coin?

Answers

Answer: 14 dimes and 26 nickels

Explanation:

Dime = 0.10$
Nickel = 0.05$

Assume that all the coins were dimes

40 x 0.10$ = 4$

4$ - 2.7$ = 1.3$

1.3$/0.05$ = 26

Thus, 26 coins are nickels.

40 - 26 = 14

And 14 coins are dime.

Let’s check:

14(0.10) + 26(0.05) = 2.7$
1.4$ + 1.3$ = 2.7$
2.7$ = 2.7$


Twila decides to purchase several party trays for her holiday party. She sees that a local store has relish trays for
$18.95, cheese and cracker trays for $23.99, and cookie trays for $25.49. The store also has a coupon in its flyer for
$5 off any purchase of $50 or more on party trays. Twila orders 1 relish, 1 cheese and cracker, and 2 cookie trays. At
this store, discount coupons are applied after tax is calculated so a sales tax of 8% was added to Twila's purchase,
and then coupon amount was deducted. If Twila was charged $96.43, determine if she paid the correct amount.
a. Twila paid the correct amount for her purchase.
b. Twila paid $4.00 too little for her purchase.
Twila paid $0.40 too much for her purchase.
d. Twila paid $2.51 too much for her purchase.
C.

Answers

Answer:

answer A. twaila paid the correct amount for her purchase

Twila has paid the correct amount for her purchase. Calculation of total amount is provided below

Find the Total Amount

Total Amount = [tex]Purchase value + Tax - Discount[/tex]

What information do we have

Price of one relish tray = $18.95

Price of one cheese & cracker tray = $23.99

Price of one cookie tray = $25.49

So,

Purchase Value = Price of 1 relish tray + 1 cheese & cracker tray + 2 cookie trays

[tex]18.95 + 23.99 + 25.49 + 25.49[/tex]

= [tex]93.92[/tex]

Tax = 8% of value

= [tex]8[/tex] % of [tex]93.92[/tex] = [tex]7.5136[/tex]

Discount = $ [tex]5[/tex]

Putting values in formula,

Total Amount = [tex]93.92 + 7.5136 - 5[/tex]

It is equal to 96.43

Hence, Total Amount paid by Twila is Correct

Answers

Answer:

he made 6 2 point shots.

Step-by-step explanation:

here's why......... 3 times 1 is 3 and 3 times 4 is 12 in total that's 15 and 27-15 is 12 and 12 divided by 2 is 6.

Answer:

This is False

Step-by-step explanation:

Because if he made 3 1-point shots then 4 3-point shots, 3 multiplied by 1 is 3 and 4 multiplied by 3 is 12, and 12 multiplied by 3 is 36. So therefore he scored a total of 36 points. Thank me later :)

A gallon of lemonade contains one cup of sugar. How many tablespoons of sugar are in 1.5 pints of lemonade?

Answers

Answer:

the number of table spoons of sugar is 48

Step-by-step explanation:

The computation of the number of table spoons of sugar is shown below:

As we know that

1 cup = 16 tablespoon = 8 ounces

1 gallon = 4 quarts

1 pint = 2 cups = 16 ounces

1 quart = 4 cups (2 pints) = 32 ounces

Given that

One gallon = one cup  of sugar

One gallon = 16 tablespoons

Now for 1.5 pints, it is

1.5 pints = 3 cups

= 16 × 3

= 48 tablespoons

Hence, the number of table spoons of sugar is 48

Answer:

the answer is 2

Step-by-step explanation:

The negative symbols make it tricky. Just remember, 2 negatives = a positive.

so x- -5 = 7

Sense 2 negatives equals positive, that means we are adding 5, not subtracting negative 5.

so our new problem is x + 5 = 7

If we run the problem backwards now, (7-5=x) then we get 2
