A man invests a certain amount of money at 2% interest and $800 more than that amount in another account at 4% interest. At the end of one year, he earned $112 in interest. How much money was invested in each account?
Which of the following equations could be used to solve the problem?
0.02x + 0.04(800) = 112
0.02x + 0.04(x + 800) = 112
0.04x + 0.02(x + 800) = 112

Marissa subtracted a negative number from a positive number. Her result was negative. Is that reasonable? Explain.
This part is 4 u Anthony
Answer:
Yes, it is reasonable
Step-by-step explanation:
Her result is reasonable because you can have a smaller positive then a negative for example 4 + -9 = -5
Answer:
it isn't
Step-by-step explanation:
It isn't reasonable. For example, 4 - -4 is equal to 8 because when two negative signs are next to each other, it becomes positive.
Without using a calculator, fill in the blanks with two consecutive integers to complete the following inequality.
\,<\sqrt{32}<\,<
32
Okay, suppose You know, 32 is between what? two perfect squares? What are perfect squares? Well, a number of times itself gives me, so like, four times itself is 16, 5 times itself is 25, 6 times itself is 36, So 32 is the closest to 25 In 36. So I'm gonna put 25 Smalling number and 36. And what I could do with this inequality is I could take the square root of all three Side. So square to 25 is in between square to 32 is in between square to 36. So square 25. What himself gives me 25 5 Is in between the square to 32 and what himself gives me 36 6. So that must mean the Square 32 is in between the Avengers five and so.

Answer:
the tens place
Step-by-step explanation:
The tens place value would help you write 50/1,000 as 5/100 because to get 50 to 5, you would need to get rid of the tens place. In other words, you would need to divide by 10.
50 divided by 10 is 5
1,000 divided by 10 is 100

Using the strategies
previously discussed
(decomposing and
composing)
, find the
area of the three
shaded figures below.
Remember that you
can count the squares
as your easiest
strategy,
but I would like for
you to use a
mathematical
strategy to find the
area of the shaded
regions. Beware of
the squares in Figure
C that are not whole
units.
Answer
A- 22 square units
B- 28 square units
C- 18 square units
Step-by-step explanation:
A. You can break it up into 3 different rectangles
(1*2)+(2*4)+(2*6)=22
B. You can first start by finding the area then subtracting the the places where it is not covered.
So the area of the whole square is 6*6=36
Now you can subtract the small squares 2*2=4.
This will be put 2 times as there are two small squares.
So you will subtract 8 square units from 36.
36-8=28
C- You can decompose C into a triangle and a rectangle.
The area of a triangle is 1/2*width*height. When you plug the dimensions in you get 1/2*6*2=6 square units.
Now to find the rectangle. The formula is width*length. Plug the dimensions in and you get 2*6=12 square units.
Just add those two together and you get 18 square units.

Whats 30 times 30 plus 45 minus 456
Answer:
489 or -113
Step-by-step explanation:
Whats 30 times 30 plus 45 minus 456
rewrite in terms of numbers:
30 * 30 + 45 - 456
remember the order of operations and solve:
30 * 30 + 45 - 456
=900 + 45 -456
= 945 - 456
= 489
the answer could change depending on the placement of parenthesis, such as if the equation was:
30 * (30 + 45 -456)
solve with the order of operations:
30 * ( 30 + 45 - 456)
= 30 * (75 - 456)
= 30 *(-381)
= -11430

Answer: Q1: D. Distribute 3 through the parenthesis
Step-by-step explanation:
As for the second question, I am not sure how to begin. Sorry
Answer:
For the first question: 3(p - 3) = 2p + 7, the first step would be to distribute 3 to both terms in the parentheses
For the second question:
6n + 11 = -7 + 3n
-3n -3n
3n + 11 = -7
-11 -11
3n = -18
3n/3 = -18/3
n = -6
Check:
6(-6) + 11 = -7 + 3(-6)
-36 + 11 = -7 + -18
-25 = -25, since these match n definitely equals -6

12 - 3/4 (d + 16) = negative 5
Answer: d=20/3
Step By Step:
Step 1, Simplify:
12-3/4(d+16)=-5
(-3/4)d+(12-12)=-5

Which property of equality can be used to solve the equation n plus nine equals negative three?
Answer: Subtraction property of equality.
Step-by-step explanation:
n + 9 = -3
You are trying to move 9 from one side to the other. To do that, you have to do the inverse operation and subtract nine from both sides. Your result would be n = -12.

A scarf that has the shape of a square and an area of 7600 cm2. Find the length of a side of the scarf to the nearest integer.
Answer:
3,800
Step-by-step explanation:
Here's how I believe I got the answer
Since the whole area is 7,600 cm2
I think that is saying that you divide in half, since that's the area. Your probably going to think about the perimeter, which divided by two, you get 3,800

1. addition property of equality
2.division property of equality
3.associative property of multiplication
4.distributive property of multiplication over addition
Answer:
Step-by-step explanation:
4 is the right answer
First step shows the "Distributive property of multiplication over addition"
What is distributive property of multiplication over addition ?
If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.
Here the equation given is : 5(x+-5) = 4 ,
and, the first step is 5x=-25 = 4
which is obtained by the distributive property of multiplication over addition where, 5 is being multiplied with x and -5 respectively.
Therefore, Distributive property of multiplication over addition is the answer.

Which of the following is equal to 4 2/3 / 3 1/2?(If you think its the answer I picked in the picture, its not) Thank you so much for you help!!
Answer:
b
Step-by-step explanation:
4 2/3= 12/3+2/3=14/3
3 2/1=7/2 but you have to flip it
so you end up with 14/3*2/7
4 2/3 = 14 / 3
3 1/2 = 7/2
An easy way to divide fractions is to find the reciprocal of the second fraction.
The reciprocal of 7/2 = 2/7
Then we multiply straight across.
