I don't know what you are talking about but this is my method ;
[tex]-20 + - 15[/tex]
It is best written as;
[tex]-20+(-15)\\\mathrm{Remove\:parentheses}:+\times - = -\\-20-15[/tex]
Note ; the bracet means multiply so + multiplied by -15

pls help due soon TY!!
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.
14/3 × 2/7

If m is a positive integer, what is the least value of m for which 180 is a factor of 105m
Answer:
Step-by-step explanation:
If 180 is the factor of 105 m, then the factors of 180 should also be the factors of 105 m.
Factors of 180 = 15 * 12
Factors of 105 m = 15 * 7 * m
The least value of m is = 12

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
(-3/4)d=-5
Step 2, Multiply each side by 4/(-3)
(4/-3)*(-3/4)d=(4/-3)*-5
d=20/3
Answer:
[tex]\bold{d=\frac{20}{3} \ or \ 6.66666666667}[/tex]
Explanation:
[tex]\bold{12-\frac{3}{4}\left(d+16\right)=-5}[/tex]
[ Subtract 12 From Both Sides ]
[tex]\bold{12-\frac{3}{4}\left(d+16\right)-12=-5-12}[/tex]
[ Simplify ]
[tex]\bold{-3\left(d+16\right)=-68}[/tex]
[ Divide Both Sides By -3 ]
[tex]\bold{\frac{-3\left(d+16\right)}{-3}=\frac{-68}{-3}}[/tex]
[ Simplify ]
[tex]\bold{d+16=\frac{68}{3}}[/tex]
[ Subtract 16 From Both Sides ]
[tex]\bold{d+16-16=\frac{68}{3}-16}[/tex]
[ Simplify ]
[tex]\bold{d=\frac{20}{3}}[/tex]
Can anyone help me with this answer
Answer:
18
Step-by-step explanation:
If you take a look at it, its quite similar to the example
Since they are using the same dimensions (1.5) you multiply 1.5 x number x 1.5 again
1/8 as a reciprocal is 8
so you do 1.5 x 8 x 1.5 which gives you 18
The are adding a new room to their house. The room will be a cube with volume 6859 ft. They are going to put in hardwood floors, and the contractor charges $5 per square foot. How much will the hardwood floors cost?
Answer:
1,371.8
Step-by-step explanation:
Here's how I got it
Since the whole square feet is 6859, and they charge 5$ per square feet, I believe if you divide 6859 divided by 5 you get 1,371.8
Sorry if I got it wrong!
Answer:
$1805 i think
Step-by-step explanation:
Cube root the volume of the room (6859) which equals 19. do 19x2=361. Do 361x5=1805. So the total would be $1805 i believe

2 and 5/8 divided by 13
a
21/104
b
25/263
c
23/110
d
22/105
Answer:
The answer is a, 21/104
Step-by-step explanation:
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
21/8 ÷13/1
Applying the fractions formula for division,
=21×18×13
=21/104
=21/104

Find the midpoint of the line segment with end coordinates of: (−3,−1)and (−4,2) Give coordinates as decimals where appropriate.
Answer:
ANSWER
M=(−72,12).
Step-by-step explanation:
The midpoint for two points P=(x1,y1) and Q=(x2,y2) is
M=(x1+x22,y1+y22).
We have that x1=−3, y1=−1, x2=−4, y2=2.
So, M=(−3+(−4)2,−1+(2)2)=(−72,12)
Answer:
The answer is
( - 3.5 , 0.5)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(−3,−1) and (−4,2)
The midpoint is
[tex]M = ( \frac{ - 3 - 4}{2} \: , \: \frac{ - 1 + 2}{2} ) \\ = ( - \frac{7}{2} \: , \: \frac{1}{2} )[/tex]
We have the final answer as
( - 3.5 , 0.5)Hope this helps you
Which equation demonstrates the distributive property?
do you want me to explain what the distributive property is????
i'm confused-
Answer:
The distributive property of multiplication states that a ( b + c ) = a b + a c . It's often used for equations when the terms within the parentheses can't be simplified because they contain one or more variables.

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.

ive got you all a challenge solve it
Answer:
γ = [tex]\lim_{n \to \infty}\sum_{k=1}^n (\frac{1}{k}-ln(n) )[/tex]
or
γ = -∞
Step-by-step explanation:
Let's solve what's inside the limit first.
We see that we need to take the sum of the entire thing. Since it is multivariable and we are given 1 variable, it stays the same.
Now we move on to the limit.
We replace n in the summative with infinity.
The natural log of infinity is infinity.
1 minus infinity would be negative infinity.
The sum of negative infinity of k = 1 is negative infinity.
So the limit as n approaches infinity would be negative infinity.
If we were to simplify this mathematically, it would just be the same equation.
Please help asap ty just for numbers 29 31 and 32
Answer:
105, D, 13,9899/138530? not sure on that one
Answer:
29.) D
31.) 145 girls
32.) 13,986 , 13,967
Step-by-step explanation:
For 29 you need to find the total cost of each item. 2x1 would be $2 for the water, 1x3 would be $3 for the sandwich. Remember what operation you used to find the products. In this case, it would be D.
For 31 you need to find the number of girls at the tournament. For that you would write out the total cost of children, and subtract the number of boys from that to get the total.
For 32 you just need 2 random numbers that will round up to 14,000. Any number that is 5 or above will round up, and any number that is 4 and under will round down.
3/8 = r + 2/3 I really need help I don't get it!!
Answer:
-7/24 = r
Step-by-step explanation:
3/8 = r + 2/3
Subtract 2/3 from each side
3/8-2/3 = r + 2/3-2/3
3/8 - 2/3 = r
Get a common denominator or 24
3/8 *3/3 - 2/3 *8/8 =r
9/24 - 16/24 =r
-7/24 = r
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.
