Answer:
x = - 18
Step-by-step explanation:
Given
- 7 + [tex]\frac{x}{3}[/tex] = - 13 ( add 7 to both sides )
[tex]\frac{x}{3}[/tex] = - 6 ( multiply both sides by 3 to clear the fraction )
x = - 18
Answer:
x = -32 or x = -18 Depends on how the equation is written
Step-by-step explanation:
-7 + x/3 = -13
Find the answer by solving for x.
If the equation is written like this:
[tex]\frac{-7+x}{3} = -13[/tex] Multiply both sides by 3 and add 7 to both sides
x = -32
Or if the equation is written like this:
[tex]-7+\frac{x}{3} =-13[/tex] Add 7 to both sides and then multiply by 3
x = -18

Answer: 9.95
Step-by-step explanation:
in similar trapezoids a rearranged formula can be used to solve for the missing base:
[tex]c^{2} =ab[/tex] ⇒ [tex]c=\sqrt{ab}[/tex]
a = the top of the trapezoid
b= the base of the trapezoid

A principal of $480 earns $108 interest in 5 years . what rate of interest was being paid?
Answer:
4.5%
Step-by-step explanation:
Solving our equation
r = 108 / ( 480 × 5 ) = 0.045
r = 0.045
converting r decimal to a percentage
R = 0.045 * 100 = 4.5%/year
The interest rate required to
accumulate simple interest of $ 108.00
from a principal of $ 480.00
over 5 years is 4.5% per year.

What is angle Bi-sector?In geometry, an angle bisector is a line that divides an angle into two equal angles. The term "bisector" refers to a device that divides an item or a form into two equal halves. An angle bisector is a ray that divides an angle into two identical segments of the same length.
Given, A triangle in that there is an angle bisector AB.
Since,
Median:
A median of a triangle is a line segment that joins a vertex to the mid-point of the side that is opposite to that vertex.
In our case, it is not specified if AB bisects the opposite line
Altitude:
The altitude of a triangle is the perpendicular drawn from the vertex of the triangle to the opposite side. Also, known as the height of the triangle, the altitude makes a right-angle triangle with the base.
In our case, it is not specified if AB makes a Right triangle or not.
Therefore, Line Ab is neither a Median nor an Altitude.

Fernando has a prime number of books between 21 and 30 he says that if he takes 4of the books away he will be able to place the same number of books on wacho shelf of this bookcase how Many books does fernando have how many shelves are on the bookcase
Answer:
29 books ; 5 bookshelfs
Step-by-step explanation:
Solving logically ;
Prime numbers between 21 and 30 = 23, 29
Hence, number of books Fernando has is either 23 or 29
Taking 4 away from the number of books, he'll be able to arrange same number of books on each of his book shelve;
From the statement, we can conclude that :
Subtracting 4 from the number of books Fernando has should give a perfect square
If 23 books
23 - 4 = 19 ; 19 isn't a perfect square
If 29 books :
29 - 4 = 25
Hence, to place the same Number of books on each shelf :
Sqrt(25) = 5
Hence, number of bookshelf = 5

A container in the shape of a pyramid has a rectangular base with dimensions of 5 inches by 15 inches. The height of the rectangular pyramid is 12 inches. Marbles fill half the volume of the container. How many more cubic inches of marbles are needed to finish filling the container?Enter your answer in the box.
{ }in3
Answer:
First you find the volume of the pyramid:
1. find the area of the base:
A= 15 x 5= 75
2. Multiply the Area of the rectangle by the height; h= 12 and si use the result by 3.
V= A x h /3 =. 75 x 12 = 900 /3
V= 300
3. If only 1/2 is filled, that means
V= 300/2= 150 in3 is filled and
150 in3 of marbles is needed to fill the container.

what is the answer for: 2(6X+5)= -3(-4X+3) ??
Answer: No Solution
Step-by-step explanation:
Given
2(6x+5)=-3(-4x+3)
Expand parenthesis
2·6x+2·5=(-3)·(-4x)+(-3)·3
12x+10=12x-9
Subtract 12x on both sides
12x+10-12x=12x-9-12x
10=-9
10 will never equal -9, which means this is No Solution
Hope this helps!! :)
Please let me know if you have any questions
Answer:
no solutions
Step-by-step explanation:
+ * - = -
- * + = -
- * - = +
+ * + = +
2 (6X + 5) = -3 (-4X+3)
- distribute
12X + 10 = 12X - 9
-10 -10
12X = 12X - 19
- 12X - 12 X
0 ≠ - 19
or you can skip all of that and just realize that there cannot be the 12X on both sides but the second term is different

brainliest if right easy question
Answer:
349,800.0 because the number 10 to the 4th power has four zeros when it is written without an exponent.
Step-by-step explanation:
34.98 x 10^4 = 349,800.0 = 349,800
34.98×10⁴ = 349,800.0 because the number 10 to the 4th power has four zeros when it is written without an exponent.
Here, we have,
given that,
the term is: 34.98 x 10⁴
now, we have to find the result of multiplication without an exponent.
so, we get,
34.98 x 10⁴
=34.98 x 10000
= 349,800.0
= 349,800
Hence, 34.98×10⁴ = 349,800.0 because the number 10 to the 4th power has four zeros when it is written without an exponent.
