What is the value of 10^-5 in standard form
what value of y makes the equation true?
3 ( 2y - 5 ) + 15 = 12
y =
To find value of y:-
________________________________
Step 1:
3 ( 2y - 5 ) + 15 = 12
Right the equation
________________________________
Step 2:
6y-15+15=12
open the brackets and multiply 3 with 2y - 5
________________________________
Step 3:
6y=12
Subtract 15 with 15 to get 0
________________________________
Step 4:
y=12÷6
divide 12 with 6 to get value for y
________________________________
Step 5:
y=2
Value of y comes 2
________________________________
Confermimng :
3(2×2-5)+15=12
3(4-5)+15=12
3(-1)+15=12
-3+15=12
12=12
hence proved
________________________________
⚡Final answer:
Y=2✓
We have to keep value of y as 2 to make the equation true✓

3/1
Step-by-step explanation:
The first step is to line the numbers up side by side:
6 =
2 = 1
SInce we know that 2 divided by 2 = 1, we divide 6 by 2, which gets us 3.
6 ÷ 2 = 3
2 ÷ 2 = 1
Remember, you must divide the numerator and the denominator by the same number.

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
Toby is installing a new storage building in the back of his yard. The building measures 10 ft. x 12 ft. He’ll need a 10 foot long, 12 foot wide, and 4 inch deep slab for the project. Help him estimate the cost of his concrete project.
Answer:
Not sure if this is correct but i believe the price would be $20,000
Step-by-step explanation:
Yoour perimeter is 120ft and it is 1/3 of a foot. So i did 120/3 and i got 40. The 40 is how many square feet you will need. you do 40x500 and i got $20,000. Sorry if this is wrong as i was kind of confused for a moment
The required cost of the concrete project is given as $740.7.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
Here,
The volume of the slab is given as,
= length × width × height
= 10 × 12 × 4/12
= 40 cubic feet,
Now,
The cost of a concrete slab is given by
= Total volume (cubic foot) x $500/27
= 40 × 500 / 27
= $740.7
Thus, the required cost of the concrete project is given as $740.7.

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

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.

First Step: 5x+−25= 4
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.

In July, the average temperature in one US city was 29°C. By December, the average temperature had fallen by 29°C. Explain why the average temperature in December was 0°C.
Answer:
Down Below :))
Step-by-step explanation:
This is quite simple.
Take a look at both of the numbers, see how their both 29?
Subtracting 29 - 29 = 0
Explanation: The average temperature was 0 because when subtracting 29 - 29, it gives you 0.
The temperature went up 29°C, which represents a positive 29. Then the temperature fell 29°C, which represents a negative 29. The average temperature rose and fell the same amount. The absolute values are the same, so the difference is 0.
