im supposed to solve this and usually ive been getting more slow at math and i used to be really great at it until my mind started flooding with thoughts and other things ever since i started getting into anime anyway the question i need to solve is -2(-4x - 8 - 3y) and i need someone to explain how i can use the distributive property to simplify it in an easy way
Answer:
8x+16+6y
Step-by-step explanation:
-2(-4x-8-3y)
Because there is no sign before the parentheses, you have to multiply -2 by everything in the parentheses:
8x+16+6y
There are no minus signs anymore because -- (minus minus) wouldn't make sense and -÷-=+ (negative÷negative=positive)
I don't think you can solve 8x+16+6y, you can only simplify.
I'm really sorry if I'm wrong, but this took me 10 minutes. Good luck :)
Kyle caught 9 insects for his science project in the first week. He caught 13 insects in the second week. What is the percent increase in the number of insects Kyle caught from the first week to the second week? Round your answer to the nearest whole number
pleaseeeee
Answer:
44%
Step-by-step explanation:
The percent increase would be calculated as the increase in insects caught divided by the original number of insects caught from the first week:
13-9 = 4 more insects caught.
4/9 = .44444
When doing percentages we multiply the decimal by 100, or move it over two places to the right, so it will be 44.4%
Numbers 4 and under round down.
Therefore,
44% is the increase

Answer:
Step-by-step explanation:
If OA is perpendicular to OC, then <OAC = 90°
<OAC = <AOB + <BOC
Given
<AOB = 6x-12
<BOC = 3x+30
On substituting this values into the formula:
6x-12+3x+30 = 90
9x+18 = 90
Subtract 18 from both sides
9x+18-18 = 90-18
9x = 72
x = 72/9
x = 8°
Since <AOB = 6x-12
<AOB = 6(8)-12
<AOB = 48-12
<AOB = 36°
Also <BOC = 3x+30
<BOC = 3(8)+30
<BOC = 24+30
<BOC = 54°

Which line coincides with y= 4x + 2?
Answer:
D. 8x - 2y = -4
Step-by-step explanation:
The line that coincides with the line represented by the equation, y = 4x + 2, is the line that has an equation that is equivalent to y = 4x + 2, or the line whose equation has the same slope (m) and y-intercept (b) as the line represented by the equation, y = 4x + 2.
A line equation is in the form of slope-intercept, is given as y = mx + b.
Thus,
The slope (m) of the line equation, y = 4x + 2, is 4, while it's y-intercept (b) is 2.
Compare each given option of line equation in their slope-intercept form, and check out which one has the same slope and y-intercept as y = 4x + 2, or has an equation equivalent to it.
Option 1: y = -4x + 2
Here, the slope (b) is -4, and y-intercept (b) is 2. This line doesn't coincide with y = 4x + 2.
Option 2: y = 4x - 2.
The slope (m) is 4, and the y-intercept (b) is -2. This line doesn't coincide with y = 4x + 2.
Option 3: 4y = x + 8
Convert to slope-intercept form
4y/4= (x + 8)/4
y = x/4 + 8/4
y = ¼x + 2
The slope is ¼. The y-intercept is 2.
This line doesn't coincide with y = 4x + 2.
Option 4: 8x - 2y = -4
Convert to slope-intercept form.
8x - 2y - 8x = -4 - 8x
-2y = - 4 - 8x
-2y/-2 = (-4 - 8x)/-2
y = -4/-2 - 8x/-2
y = 2 + 4x
y = 4x + 2
The slope is 4 and the y-intercept is 2. Therefore, 8x - 2y = -4 coincides with y = 4x + 2.

What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Linear equations may include one or more variables.
Given the linear equation,
w = 1/9 (x + y + z)
We have the distributive property which states that,
For any three numbers, p, q and r, p (q + r) = (p q) + (p r)
So applying distributive rule in the expression given, we get,
w = (1/9 x) + (1/9 y) + (1/9 z)
w = x/9 + y/9 + z/9
Hence the given linear equation w = 1/9 (x + y + z) can be written as w = x/9 + y/9 + z/9.

Three out of seven soccer players wore headbands in a soccer league. a. Write the ratio of soccer players who wore headbands to soccer players who did not. b. If there were 36 players in the league who did not wear headbands, how many players were in the league?
Answer:
a. 3:4
b) 63 players
Step-by-step explanation:
From the question, we know that: Three out of seven soccer players wore headbands in a soccer league.
This means Number of soccer players who did not wear head bands = 7 - 3
= 4
a. Write the ratio of soccer players who wore headbands to soccer players who did not.
Soccer player who wore headbands : Soccer players who did not
= 3:4
b. If there were 36 players in the league who did not wear headbands, how many players were in the league?
Soccer player who wore headbands : Soccer players who did not
= 3:4
36 players in the league who did not wear headbands
Hence, number of players in the league who wore head bands is calculated as:
3/4 = x/36
Cross Multiply
4x = 3 × 36
x = 3 × 36/4
x = 27
The total number of players in the league
= 27 + 36
= 63 players
