Answer:
x = - 18
Step-by-step explanation:
Let certain number = x
The difference between half of a certain number and seven
x/2 - 7
is the same as
=
with adding two to that number
x + 2
Find the number
x/2 - 7 = x + 2
x - x/2 = - 7 - 2
( 2x - x ) / 2 = -9
2x - x = -18
x = - 18

Complete this statement using >,<, or =
- 12
-41
Answer:
>
Step-by-step explanation:
-12 is closer to 0 than -41 would be therefore -12>-41.
Answer:
>
Step-by-step explanation:
Looking at a number line, -41 is farther from 0 than -12.
See the image below.
The farther left a number is on a number line, the smaller it is.
The farther right a number is on the number line, the larger is it.
So:
-12 > -41

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form.
4, 9, 14....
Answer:
The sequence is geometric
The common ratio is 0.5
Step-by-step explanation:
In the arithmetic sequence, there is a common difference between each two consecutive terms
In the geometric sequence, there is a common ratio between each two consecutive terms
Let us check the given sequence
The first 3 terms are 12, 6, 3
6 - 12 = -6
3 - 6 = -3
There is no common difference between the consecutive terms
The sequence is not an arithmetic sequence
6 ÷ 12 = 0.5
3 ÷ 6 = 0.5
There is a common ratio between each two consecutive terms
The sequence is a geometric sequence
The common ratio is 0.5
Answer:
An arithmetic
Common difference
-5

she borrows a loan of 5000 from a loan company the loan company charges 6%how much the simple intrest
Answer:
300
Step-by-step explanation:
Given data
P=5000
R= 6%
T= 1 year
The simple interest formula is
SI= PRT/100
SI= 5000*6*1/100
SI= 30000/100
SI= 300
Hence the simple interest is 300

vera está usando su teléfono. Su batería está a 2/5 de capacidad, y esta baja 1/9 cada hora. ¿Cuántas horas durará la batería?
Answer:
3.6 hours
Step-by-step explanation:
The computation of the number of hours will the battery last is given below:
Given that
The capacity of her battery is 2 by 5
And, it declines 1 by 9 for every hour
So,
[tex]= \frac{2}{5}\times \frac{9}{1}\\\\= \frac{18}{5}\\\\= 3\frac{3}{5}[/tex]
= 3.6 hours

1)
Fact :: Reason
∠DCE = 90° :: sin ∠EDC = sin 30° = 1/2 = 8/16 = CE/DE
∠ACB = 90° :: ∠DCE and ∠ACB are vertical angles
∠ABC = 60° :: 180 - ∠CAB - ∠ACB = 60°
∠CED = 60° :: 180 - ∠EDC - ∠DCE = 60°
△CDE ⁓ △ABC :: Same angles (AAA)
2)
Let's solve for AB
sin 30° = 1/2
sin 30° = BC/AB = 15/AB
1/2 = 15/AB ⇒ AB = 30
AB = 30 in
Let's solve for AC (using another way)
AC/12 = 15/8
AC = 12 * 15 / 8 = 22.5
AC = 22.5 in

Write the slope-intercept form of the equation of the line.
slope = -10, y-intercept = 5
Write the slope-intercept form of the equation of the line.
through: (-5,-1), slope = 2/5
Write the slope-intercept form of the equation of the line.
through: (5,0) and (-5,2)

Write the slope-intercept form of the equation of the line.
through: (4,1), perpendicular to y = -2x + 5
Answer:
y = -10x + 5 and y = 2/5x + 1
Step-by-step explanation:
slope-intercept form is y = mx + b, where m = slope and b = y-intercept.
for your first problem, just plug in the m and b values to complete the equation.
1.) y = mx + b ⇒ y = -10x + 5
plug in -10 for x (slope) and 5 for b (y-intercept)
and for the second problem...
since you're given a value for slope as well as a coordinate pair, all you need to do is plug those values into the equation for their respective variables and then solve for b. (it doesn't matter what order you plug values in, but i'm going to fill them in in the order of the equation; y, m, and x)
1.) plug in -1 for y
y = mx + b ⇒ -1 = mx + b
2.) plug in 2/5 for m
-1 = mx + b ⇒ -1 = 2/5x + b
3.) plug in -5 for x
-1 = 2/5x + b ⇒ -1 = 2/5(-5) + b
now it's time to solve for b! start by multiplying 2/5 and -5.
-1 = 2/5(-5) + b ⇒ -1 = -2 + b
add 2 to both sides of the equation. on the right side, it cancels itself out. on the left side, adding 2 to -1 gives you 1.
and you're left with 1 = b! :)
therefore, y = 2/5x + 1
i hope this helps! have a great day <3

Marbles:
5 red
3 green
4 yellow
Total marbles = 5 + 3 + 4 = 12.
The probability of picking a green marble is 3/12, since there are 3 green marbles possible to grab and 12 total. 3/12 can be reduced to 1/4, or .25. Devon has a 25% chance of picking a green marble.
