Multiplication is a way to represent repeated addition. ... Instead, we can write this repeated multiplication using an exponent, which is the number of repeated factors. Exponents are written as a superscript number to the right of the number being multiplied.
Answer:
Step-by-step explanation:
Simplifying
3.4 + 2(9.7 + -4.8x) = 61.2
3.4 + (9.7 * 2 + -4.8x * 2) = 61.2
3.4 + (19.4 + -9.6x) = 61.2
Combine like terms: 3.4 + 19.4 = 22.8
22.8 + -9.6x = 61.2
Solving
22.8 + -9.6x = 61.2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-22.8' to each side of the equation.
22.8 + -22.8 + -9.6x = 61.2 + -22.8
Combine like terms: 22.8 + -22.8 = 0.0
0.0 + -9.6x = 61.2 + -22.8
-9.6x = 61.2 + -22.8
Combine like terms: 61.2 + -22.8 = 38.4
-9.6x = 38.4
Divide each side by '-9.6'.
x = -4
Simplifying
x = -4
Answer:
Step-by-step explanation:
If the extreme ends of a line segment AC are A
and C
.
If a point B(x, y) divides the segment in the ratio of m : n
Then the coordinates of the point B are,
x = 
y = 
If the ends of AC are A(-2, 5) and C(2, -5) and a point B divides it in the ratio of m : n = 5 : 1
Therefore, coordinates of this point will be,
x = 
= 
= 
= 
y = 
= 
= 
= 
Therefore, coordinates of the point B are .
