Answer:
Indices are used to show numbers that have been multiplied by themselves. They can also be used to represent roots, such as the square root, and some fractions. The laws of indices enable expressions involving powers to be manipulated more efficiently than writing them out in full.
Using indices
An index, or power, is the small floating number that appears after a number or letter. The plural of index is indices. Indices show how many times a number or letter has been multiplied by itself.
Step-by-step explanation:
use the distributive property 15(4n-2)=
Answer:
60n-30
Step-by-step explanation:
you would do 15 * 4n
that would give you 60. since 15 *4 is 60 and then you would just put the n
15*2 equals 30. You would make it a negative 30 since it is a negative 2.
then you would combine them and get the answer
60n-30

Solve the y for the equation 5x-2y=10
Answer:
y = 5/2x - 5
Step-by-step explanation:
Step 1: Write equation
5x - 2y = 10
Step 2: Solve for x
Subtract 5x on both sides: -2y = 10 - 5xDivide both sides by -2: y = -5 + 5/2xRewrite: y = 5/2x - 5Answer:
y = (5/2)x - 5
Step-by-step explanation:
5x-2y = 10
Subtract 5x from both sides
-2y = 10 - 5x
Rearrange
-2y = -5x + 10
divide both sides by -2 to isolate y
y = (5x/2) + (10/-2)
y = (5/2)x - 5

Find the value of X.
to
67°
56°
Answer:
x = 57
Step-by-step explanation:
180 degrees in a triangle
67 + 56 = 57
==================================================
Explanation:
The three angles of any triangle always add to 180
x+67+56 = 180
x+123 = 180
x+123-123 = 180-123 .... subtract 123 from both sides
x = 57
The missing angle is 57 degrees
-------------
Check:
x+67+56 = 57+67+56 = 180

A line crosses through the points (0,2) and (-10, -16) Which of the following is the slope of the line?
A
[tex] \binom{9}{5} [/tex]
b
[tex] - \binom{9}{5} [/tex]
c
[tex] \binom{1} {3} [/tex]
d
[tex] \binom{5}{9} [/tex]
Answer:
9/5
Step-by-step explanation:
The slope between the two points can be found by ...
m = (y2 -y1)/(x2 -x1)
m = (-16-2)/(-10-0) = -18/-10
m = 9/5
The slope of the line is 9/5. Perhaps this is a match to choice A.
Answer: 9/5
m = (y2 -y1)/(x2 -x1)
m = (-16-2)/(-10-0) = -18/-10
m = 9/5

b is a point between a and c where ac = 5x, ab = 12, and bc = 3x + 2. what is the measure of the length of ac?
Answer:
AC=22
Step-by-step explanation:
The measure of the Length of AC is; 35
We are given;
ac = 5x
ab = 12
bc = 3x + 2
We are told that b is between a and c. This means that;ab + bc = ac
Thus;
12 + 3x + 2 = 5x
14 + 3x = 5x
Subtract 3x from both sides to get;
5x - 3x = 14
2x = 14
x = 14/2
x = 7
Thus, ac = 5x = 5 * 7ac = 35

PLEASE HELP! MUCH APPRECIATED. MATH IS SO HARD :(
Answer:
see below
Step-by-step explanation:
x+ 7.05 = 45.3
Subtract 7.05 from each side
x+ 7.05-7.05 = 45.3-7.05
x =38.25
Let x be the number
x+3.5 = -4.3
Subtract 3.5 from each side
x+3.5 - 3.5 = -4.3-3.5
x = -7.8
x is the cost of the drawing tablet
x+ 3.95 = 6.94 correct
The second equation add the total cost plus the cost of the drawing tablet and sets it equal to the cost of the pencils. This is not correct
6.94+x = 3.95 incorrect
Answer:
1. x=38.25
2. -7.8
3. the second option
Step-by-step explanation:
1. x+7.05=45.3
(move the constant to the right)
x=45.3-7.05
(calculate)
x= 38.25
(answer)
2.
(you subtract -4.3 by 3.5)
3.
(you can't use $6.94 + x = $3.95 because $6.94 is your total overall so you can only use that as your end result)
