10x +7 = -3х – 3 help guys
Answers
Answer:
x = -10/13
Step-by-step explanation:
10x + 7 = -3x - 3
Add 3x to both sides
10x + 3x + 7 = -3x + 3x - 3
13x + 7 = 0x - 3
13x + 7 = -3
Subtract 7 from both sides
13x + 7 - 7 = -3 - 7
13x + 0 = -10
13x = -10
Divide both sides by 13
13x ÷ 13 = -10 ÷ 13
1x = -10/13
x = -10/13

Roberto must make his costume for the school play. He needs a piece of fabric that is 2 and 2/3 yards long and 1 and 1/2 yards wide. What is the area of the piece of fabric Roberto needs?
Answers
Answer:
4 yd².
Step-by-step explanation:
From the question given above, the following data were obtained:
Length (L) = 2⅔ yards
Width (W) = 1½ yards
Area (A) =.?
The area of the piece of fabric that Roberto needs can be obtained by using the formula for calculating the area of a rectangle. This is illustrated below:
Area (A) = Length (L) × Width (W)
A = 2⅔ × 1½
A = 8/3 × 3/2
A = 8 × ½
A = 4 yd²
Thus, the area of the piece of fabric that Roberto needs is 4 yd²

what percentage of 25kg is 15kg
Answers
Answer:
1.6 repeating
Step-by-step explanation:
25 divided by 15 is 1.6666... and to check your math you could multiply that answer by 15, and that would give you 25
15kg is 60 percent of 25kg, which means that if we take 25kg and divide it into 100 parts, 60 of those parts will be 15kg.
To calculate the percentage of 25kg that is 15kg, we can use the following formula:
percentage = (part / whole) * 100
In this case, the part is 15kg and the whole is 25kg. So, the percentage is:
percentage = (15kg / 25kg) * 100
= 60%
Therefore, 15kg is 60% of 25kg.
To understand this in more detail, let's break down the formula. The first part, (part / whole), is simply the fraction of the whole that is the part. In this case, the part is 15kg and the whole is 25kg, so the fraction is 15/25.
The second part, * 100, simply converts the fraction to a percentage. So, 15/25 * 100 = 60%.
In other words, 60% of 25kg is 15kg. This means that if we take 25kg and divide it into 100 parts, 60 of those parts will be 15kg.

Well, the prime factorization would be 17 itself! This happens because 17 is a prime number.
If we take another example, like 13 or any other prime number, this will occur. Since 1 isn't a prime number, nor composite number, we won't include 1. Therefore, the prime factorization of 13 would also be 13 itself.

Find the diagram attached. In Line geometry, there is a theorem that states that the sum of the adjacent interior angles is 180 degrees. According to the diagram, the adjacent interior angles are 7x- 15 and 24x + 9.
The sum of this angles must give 180 degrees as shown;
7x-15 + 24x + 9 = 180
7x+24x-15+9 = 180
31x-6 = 180
31x = 180+6
31x = 186
x = 186/31
x = 6
Hence the value of x is 6 degrees

The missing values of the given quadratic function are option (b)-19,-15,-9,-1,9
What is a quadratic function?Quadratic function is an function which contains one unknown variable and the highest power of this unknown variable is 2. Let x be the unknown variable then the quadratic function y in x is given by
y = ax²+bx+c, where a, b, c are constants and a≠0
Given that a quadratic function y is:
y = x² +7x -9
Value of y when x = -2
y(-2) = (-2)² +7(-2) -9 = -19
Value of y when x = -1
y(-1) = (-1)² +7(-1) -9 = -15
Value of y when x = 0
y(0) = (0)² +7(0) -9 = -9
Value of y when x = 1
y(1) = (1)² +7(1) -9 = -1
Value of y when x = 2
y(2) = (2)² +7(2) -9 = 9
The missing values in the table are -19,-15,-9,-1,9
Therefore, option b is correct option.

For what value of a is the volume of the tetrahedron formed by the coordinate planes and the plane (x/a) (y/10) (z/6)
Answers
This question is incomplete, the complete question is;
For what value of a is the volume of the tetrahedron formed by the coordinate planes and the plane (x/a) + (y/10) + (z/6) = 1 equal to 10?
Answer: the value of a is 1
Step-by-step explanation:
Given that;
Volume of tetrahedron bounded by plane (x/a) + (y/10) + (z/6) = 1
and coordinate plane is; V = 1/6|abc|
(x/a) + (y/10) + (z/6) = 1
volume = 10
so
10 = 1/6 | a × 10 × 6 |
60 = a × 10 × 6
60 = 60a
a = 60 / 60
a = 1
Therefore the value of a is 1
