- What is the missing number for this equation? (-3) + _____ = -7
-What is the missing number for this equation ? ______ + (-23) = -11
Answers
2= 12
a negative plus a negative will always be a negative. Think of it as pouring 3 negatives and 4 negatives into a pot. You would just end up with 7 negatives
subtract 23-11 to get 12.
Answer:
The first one is -4 and the second one is 12. all you will need to do is change the + to a - then do for the first one which would be -7- -3= -4 so to check it you will need to use the + to check it so it will be -3+-4=-7. and for the second one you will need to do -11- -23=12 so to check it you will need to change the - to + so it will be set up as 12+ -23=-11.

Maxwell invested a total of $100,000. He invested his money in three different accounts. He invested $35,000 at 10% annual interest rate, $42,000 at 8% annual rate, and the remainder at 14% interest rate. How much interest did Maxwell receive in one year?
Answers
Step-by-step explanation:
Sure! Here's the step-by-step calculation:
1. Calculate the interest earned on the first investment:
$35,000 * 10% = $3,500
2. Calculate the interest earned on the second investment:
$42,000 * 8% = $3,360
3. Calculate the amount invested in the third account:
Total investment - (First investment + Second investment)
$100,000 - ($35,000 + $42,000) = $23,000
4. Calculate the interest earned on the third investment:
$23,000 * 14% = $3,220
5. Add up the interest earned from all three investments:
$3,500 + $3,360 + $3,220 = $10,080
Therefore, Maxwell received $10,080 in interest in one year.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

During a 20% off sale, the sale price of a microwave was $60. The sale has expired but Kristen has a coupon good for 15% off the regular price of any one item. How much will Kristen pay for the microwave before tax? Round to the nearest cent.
Answers
Answer:
it would take 9 dollar OFF!! so subtracted by 60 your welcome!!
(its 51 just saying.)
Step-by-step explanation:
x - 0.2x = 60
Simplifying the left side, we get:
0.8x = 60
Dividing both sides by 0.8, we get:
x = 75
So the regular price of the microwave is $75. Now, we can use Kristen's coupon to find the price she will pay:
Regular price = $75
Discount from coupon = 15%
Amount of discount = 0.15 x $75 = $11.25
Subtracting the discount from the regular price, we get:
Price after coupon = $75 - $11.25 = $63.75
Therefore, Kristen will pay $63.75 for the microwave before tax.
a skateboard is $45.87. it is on sale for 10% off. the sales tax is 8.25%. what is the final cost?
Answers
===================================================
Explanation:
The skateboard is on sale for 10%, which means that you save that percentage but have to still pay the remaining 90% of the original cost (note the percentages add to 100%)
This means we'll be involving the multiplier 0.90
We'll also be involving the multiplier 1.0825 which represents an increase of 8.25% (because 100% + 8.25% = 1 + 0.0825 = 1.0825)
Chaining the multipliers together is as straightforward as multiplying those values: 0.90*1.0825 = 0.97425
The order doesn't matter because we can multiply in any order.
The final multiplier is 0.97425 which tells us the final cost is
45.87*0.97425 = 44.6888475 = 44.69 dollars

Find the surface area of the prism. Write your answer as a decimal.
A triangular prism. The base triangle is a right triangle with base of 10 inches, height of 9 inches, and hypotenuse of 13.5 inches. The height of the prism is 9 inches.
Answers
Answer:
5
Step-by-step explanation:
9×9 - 13.5 ÷10=9 =*÷&#>÷<$<÷>#*#*#*#*#*=*/&=
The area of the triangular base is:
Area = (1/2) * base * height = (1/2) * 10 in * 9 in = 45 in^2
The area of the three rectangular faces is:
Area = length * width
For the rectangular face adjacent to the base triangle, the length is the hypotenuse of the base triangle, which is 13.5 inches, and the width is the height of the prism, which is 9 inches. Therefore, the area is:
Area = 13.5 in * 9 in = 121.5 in^2
For the other two rectangular faces, the length is the hypotenuse of a right triangle with legs of 9 inches and 10 inches, which can be found using the Pythagorean theorem:
c^2 = a^2 + b^2
c^2 = 9^2 + 10^2
c = sqrt(81 + 100) = sqrt(181) ≈ 13.45 in
The width is still 9 inches, so the area of each face is:
Area = 13.45 in * 9 in ≈ 121.05 in^2
Therefore, the total surface area of the prism is:
Surface Area = 2 * Area of Base + 3 * Area of Rectangular Face
Surface Area = 2 * 45 in^2 + 3 * 121.05 in^2 ≈ 549.15 in^2
Rounding to two decimal places, the surface area of the prism is approximately 549.15 in^2.

What is the retail price of a phone?
Next week the store is going to reduce the price to $31.50. Calculate what percent the sale price is of the retail price.
Think of the retail price of the phone as 100%. How does the sale price compare to the retail price? What does this tell you about the markdown rate? The sale price is ??% less than the retail price. The markdown rate is ??%.
What is an equation in the form y=kx that relates the sale price to the retail price x?
Answers
An equation that can be used to find the markup on the cost x of a phone is y = 2.50x, where y represents the markup amount.
Using the equation, the markup amount can be calculated as y = 2.50($12) = $30.
The retail price of a phone is the cost price plus the markup amount, which is $12 + $30 = $42.
The percent the sale price of $31.50 is of the retail price $42 can be calculated as (31.50/42) x 100% = 75%.
The sale price is 25% less than the retail price. Therefore, the markdown rate is 25%.
An equation in the form y=kx that relates the sale price to the retail price x is y = 0.75x, where y represents the sale price.
