the answer is 11
-4 - (-15) = 11
if the original quantity is 12 and the new quantity is 15, what is the percentage increase? The percent increase is _____%
Answer:
25%
Step-by-step explanation:
Given data
original quantity =12
new quantity =15
% increase= new-original/original *100
% increase= 15-12/12 *100
% increase= 3/12 *100
% increase=0.25 *100
% increase=25%
hence the increase is 25%.

Step-by-step explanation:
The sum of a number and two times a smaller number is 62 .Three times the bigger number exceeds the smaller number by 116 .
What is the biggest number and the smallest number??
Answer:
42,10
Step-by-step explanation:
let the numbers be x and y and x>y
x+2y=62
3x-y=116
multiply by 2
6x-2y=232
add the first
7x=294
x=42
from first
42+2y=62
2y=62-42=20
y=20/2=10
Pls help me I am freaking out. :(
A submarine is at an elevation of -100 feet (100 feet below sea level). Let’s compare the elevations of these four people to that of the submarine:
Clare’s elevation is greater than the elevation of the submarine. Clare is farther from sea level than the submarine.
Andre’s elevation is less than the elevation of the submarine. Andre is farther away from sea level than the submarine.
Han’s elevation is greater than the elevation of the submarine. Han is closer to sea level than is the submarine.
Lin’s elevation is the same distance away from sea level as the submarine’s.
1. Complete the table as follows.
Write a possible elevation for each person.
Use <, >, or = to compare the elevation of that person to that of the submarine.
Use absolute value to tell how far away the person is from sea level (elevation 0).
As an example, the first row has been filled with a possible elevation for Clare.
Andre : Anything less than -100, for example -150
-150<-100
|-150|=150
Han: Anything between -100 & 100, for example 50
50> 100
|50|= 50
Lin: 100 or -100,
100> -100
|100|=100
or
-100=-100
|-100|=100

A volleyball player’s serving percentage is 90%. Six random serves are selected. What is the probability that 5 of those serves were successful?
0.09
0.35
0.59
0.90
Answer:
C (.35) on edge2021! :)
Step-by-step explanation:
for this problem we use the formula P(X = k) = (n over k)p^k(1-p)^n-k and in this case,
k = 5
n = 6
p = .90
and (n over k), n choose k, is calculated by (n! / k!(n-k)!) or just look up "6 choose 5" and you'll figure out that it's equal to 6.
so you end up with P(X = 5) = 6(.90)^5(1-.90)^6-5 which will give you .35 when put in a calculator.

16. What is the solution when you take the square root of a negative number? A. Any positive value B. No Solution C. Any negative value D. All Solutions
Answer:
A: Any positive value
Step-by-step explanation:
Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.
Answer:
A: Any Postive value or B: No Solution
Step-by-step explanation:
Zero has one square root which is 0. Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.

3(8 - 4x) = 12
Please help. You have to use distributive property to solve.
Answer:
x=1
Step-by-step explanation:
First, we distribute the 3 to the 8 and the 4x.
Now we have 24-12x=12
Then, we subtract 24 from 12
Now we have -12x=-12
Finally, we devide -12 by -12
Now we have x=1

what is the answer to 2(3x-5) = 4x+2? Well not the answer but like the steps to solving it
Answer:
x=6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(3x−5)=4x+2
(2)(3x)+(2)(−5)=4x+2(Distribute)
6x+−10=4x+2
6x−10=4x+2
Step 2: Subtract 4x from both sides.
6x−10−4x=4x+2−4x
2x−10=2
Step 3: Add 10 to both sides.
2x−10+10=2+10
2x=12
Step 4: Divide both sides by 2.
2x=12
x=6

what is 4x - y = - 20 in y=mx+b form
Answer: y = 4x + 20
Step-by-step explanation:
4x - y = -20
=> -y = -4x - 20
=> y = 4x + 20
Answer:
4x - y = - 20 in y=mx+b form is: y = 4x + 20
Step-by-step explanation:
Given the equation
[tex]4x - y = - 20[/tex]
What is the slope-intercept form of linear/line function?
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
[tex]m[/tex] represents the slope[tex]b[/tex] represents the y-interceptConverting the equation into the slope-intercept form of the line equation
[tex]4x - y = - 20[/tex]
Add -4x to both sides
[tex]4x-y+\left(-4x\right)=-20+\left(-4x\right)[/tex]
simplify
[tex]-y=-20-4x[/tex]
Divide both sides by -1
[tex]\frac{-y}{-1}=-\frac{20}{-1}-\frac{4x}{-1}[/tex]
Simplify
[tex]y=4x+20[/tex]
Therefore, 4x - y = - 20 in y=mx+b form is: y = 4x + 20

help please!! i don’t know geometry :(
Answer:
the answer is 180 degrees
Answer:
20 degrees
Step-by-step explanation:
since JIH is equal to 25x+5 degrees, then JIZ and ZIH together equal that. but, since it's a straight line, JIH equals 180, so you can set 25x+5 equal to 180. therefore, x equals 7. then you can plug in 7 for x for JIZ and you get 2(7)+6 or 20.
