5. If -5(-2x + 10) is equivalent to 10x + b, what
is the value of b?
Answer:
b = - 50
Step-by-step explanation:
Using F.O.I.L (First Outer Inner Last)
-5 × - 2x = 10x
-5 × 10 = - 50
10x - 50
10x - 50 = 10x + b
10x - 10x - 50 = b
b = - 50
if 1m is 100cm, then 250cm equivalent of 2.5m
if 1kg is 1.00g then 3kg is 2.500g
Answer:
I Kg = 1000 g
3 Kg = 3000 Kg
Step-by-step explanation:
Kg - Hg - Dag - g
1 Kg - 10 Hg - 100 Dag - 1000 g
So, 1 Kg = 1000 g
3 Kg = 3(1000)g = 3000 g

Step-by-step explanation:
.30,36,P,40,44 average is 35 find the value of p
sum of number=30+36+p+40+44=150+p
n=5
average=35
Step-by-step explanation:
average=sum of number÷n
35=150+p÷5
35×5=150+p
175-150=p
25=p
p=25
Answer:
P=25
Step-by-step explanation:
Hi! Let's start with with the average...
First we multiply 35 by the amount of numbers we have
We have 5 including the unidentified
so...
35x5=175
Now since we have 175 we have to add all the other numbers together
30+36+40+44=150
Next we subtract
175-150= 25
P= 25
To check our answer add all of them together
40+30+40+44+25=175
We were right!
Hope this helps! :)

Graph a line that contains the point (-5,-3) and has a slope of −2
Heyo! ;D
So, considering this is talking about slope, it follows the rule of Δx over Δy, aka [tex]\frac{rise}{run}[/tex].
This being said, the easiest way to solve this would be to first determine the location of the points. All you need to do is convert the given slope (-2) into a point. Bare in mind that 2 is the y (run) and 1 is the x (rise).
[tex]-2 = -\frac{2}{1} = (1, -2) = (-1, 2)[/tex]Next, use the given points from the question (-5, -3) with your new points, at them together separately, like this:
[tex](-5, -3) + (1, -2)[/tex][tex](-5 + 1, -3 + (-2))[/tex][tex](-5 + 1, -3 - 2)[/tex][tex](-4, -5)[/tex]^This is adding (-5, -3) to (1, -2).
Hence, your first point will be (-4, -5).
Now, we add (-5, -3) to (-1, 2).
[tex](-5, -3) + (-1, 2)[/tex][tex](-5 + (-1), -3 + 2)[/tex][tex](-5 - 1, -3 + 2)[/tex][tex](-6, -1)[/tex]Hence, your second point would be (-6, -1).
I attached a really helpful graph that can help you confirm your work. Otherwise, hope this helped you at the least move you closer to your answer! If this helped you, please lmk! Tysm, and good luck!

The average (mean) of five numbers is 30.
Four of the numbers are 21, 29, 18 and 32.
What is the fifth number?
Answer:
50
Step-by-step explanation:
x/5 = 30
= 30 x 5
= 150
150 - (21 + 29+ 18 + 32)= 50
the fifth number is 50.
The fifth number is 50 and this can be determined by using the formula of the mean and also by using the arithmetic operations.
Given :
The average (mean) of five numbers is 30. Four of the numbers are 21, 29, 18, and 32.Let the sum of five numbers be 'x'. Then the mean is given by the formula:
[tex]\rm Mean =\dfrac{Sum\;of\;all\;data}{Total \; number\;of\;data}[/tex]
Now, substitute the known values in the above expression.
[tex]30=\dfrac{x}{5}[/tex]
x = 30 [tex]\times[/tex] 5
x = 150
So, the sum of five numbers is 150 that is:
21 + 29 + 18 + 32 + a = 150
where 'a' is the fifth number.
Simplify the above expression in order to find the fifth number.
100 + a = 150
a = 150 - 100
a = 50
So, the fifth number is 50.

Find the distance in units between 1 1/2 and −2 5/6 on a number line.
Answer:
4 1/3
Step-by-step explanation:
Hypothetically, imagine 2 5/6 was postive, you add it to 1 1/2 to get your answer, but you cant do that until the fractions have a common denominator. To get a common denominator of six, you would multiply both the numerator and denominator of 1/2 by 3, giving you 3/6. Now you have 2 5/6 and 1 3/6, adding them together gives you 3 8/6, but we cant stop here, since 8/6 is 1 2/6, add 3+1 and you now have 4 2/6. The last thing you do here is simplyfy the fraction making it 1/3 now instead of 2/6. Giving you a final answer of 4 1/3 units.

please mark me brainliest pleaseHyla has blocks of clay that are each 4 centimeters by 4 centimeters by 2 centimeters. She needs to cover the bottom of a box with a 2-centimeter tall layer of clay. The bottom of the box is 24 centimeters long and 20 centimeters wide. How many blocks of clay does Hyla need?
Answer:
12 or 10 blocks of clay
Step-by-step explanation:
If this is correct please give me brainliest.
Hyla needs 30 blocks of clay to cover the bottom of the box with a 2-centimeter-tall layer of clay.
What is the area?Area is a measure of the size of a two-dimensional surface or region. It is the amount of space inside a shape, usually measured in square units, such as square meters or square feet.
The area is an important concept in geometry and is used in many fields, including physics, engineering, and architecture, among others.
The solution to this question is:
The area of the bottom of the box is:
24 cm x 20 cm = 480 cm^2
Since the layer of clay needs to be 2 cm tall, the volume of clay needed to cover the bottom of the box is:
480 cm^2 x 2 cm = 960 cm^3
Each block of clay has a volume of:
4 cm x 4 cm x 2 cm = 32 cm^3
So, to find how many blocks of clay Hyla needs, we can divide the volume of clay needed by the volume of each block:
960 cm^3 ÷ 32 cm^3/block = 30 blocks of clay
Therefore, Hyla needs 30 blocks of clay to cover the bottom of the box with a 2-centimeter-tall layer of clay.
