-4x< 8 help please solving one step inequalities
Answer:
x>-2
Step-by-step explanation:
when dividing by a negative number, the inequality sign flips.
Answer:
x > -2
Step-by-step explanation:
-4x< 8 (divide both sides by -4)
-x < 8/4
-x < 2 (divide or multiply both sides by -1, remember to flip the inequality when multiplying or dividing by -1)
x > 2 (-1)
x > -2
What is the solution to the system?
1/2x + 3/2= -7
-3x + 2y = -2
Answer: (-2, -4)
Answer:
the (x, y) pair solution to the system is: (-2, -4)
That is x = -2 and y = -4
Step-by-step explanation:
I presume there is a variable y missing in the first equation, and in fact the system looks like:
(1/2) x + (3/2) y = - 7
- 3 x + 2 y = -2
In such case, we proceed to multiply both sides of tye first equation by 6
6 (1/2) x + 6 (3/2) y = - 42
3 x + 9 y = - 42 and we add term by term this equation to the second one, so as to cancel out the term in x:
3 x + 9 y = - 42
- 3 x + 2 y = -2
_____________
11 y = - 44
divide both sides by 11 to isolate y
y = -44 / 11 = -4
Then with the value y = -4, now we replace it in the second equation to solve for x:
- 3 x + 2 y = - 2
- 3 x + 2 (- 4) = -2
- 3 x - 8 = - 2
add 8 to both sides
- 3 x = 6
divide both sides by (-3) to isolate x
x = 6 / (-3) = - 2
Therefore the (x, y) pair solution to the system is: (-2, -4)
That is x = -2 and y = -4
13) Assume the current cost of milk is $2.70.
Given an annual inflation rate of 3% how
much will milk cost in 30 years?
9514 1404 393
Answer:
$6.55
Step-by-step explanation:
The cost will be multiplied by 1 +3% = 1.03 each year, so after 30 years, the cost will be ...
$2.70 × 1.03^30 ≈ $6.55

4 3/20 as a fraction
Answer: 83/20
Step-by-step explanation:
Take a mixed number (whole number with a fraction) and turn it into an improper fraction (numerator is more than the denominator)
To do this, multiply the denominator (20) by the whole number (4) and add the numerator (3) to it. 20x4+3= 83. This is your new numerator. Now just simply write this over the original denominator of 20. = 83/20
Solve this system by substitution, y = 4x + 12. -3x + 2y = 4
Step-by-step explanation:
in equation 1
y=4x+12
so now
eqs 2
2y=4+3x
then
-y=x+8
y= -x-8
so
-x-8=4x+12
-20=5x
-4=x
so
y= 4-8
y=-4
Find exact radius of circle please help!
===========================================================
Explanation:
Let r be the radius we want to find
The area of the full circle is A = pi*r^2
The unshaded portion is 60 degrees, so the unshaded portion must be 360-60 = 300 degrees.
The full area was pi*r^2, but we only want 300/360 of that full area.
So,
s = shaded area
s = (300/360)*(full circle area)
s = (300/360)*(pi*r^2)
s = 30pi
(300/360)*(pi*r^2) = 30pi
(300/360)*r^2 = 30
(5/6)*r^2 = 30
5r^2 = 30*6
5r^2 = 180
r^2 = 36
r = sqrt(36)
r = 6
The radius is 6 inches.

Iconic memory is a type of memory that holds visual information for about half a second (0.5 seconds). To demonstrate this type of
memory, participants were shown three rows f four letters for 50 milliseconds. They were then asked to recall as many letters as possible,
with a 0., 0.5-, or 1.0-second delay before responding. Researchers hypothesized that longer delays would result in poorer recall. The
number of letters correctly recalled is given in the table.

Mr. Jimerson records the amount of snowfall that the local area recieves. 12am-1am: 0.3 inches | 1am-2am: 0.8 inches | 2am-3am: 1.36 inches |3am-4am: 2.019. If the total amount of snowfall at 7am is 7.8 inches. How much snow fell between 4am-7am? hurry pls
Answer:
5.781 inches.
Step-by-step explanation:
Since Mr. Jimerson records the amount of snowfall that the local area recieves, recording the following data: 12 am-1am: 0.3 inches | 1 am-2am: 0.8 inches | 2 am-3am: 1.36 inches | 3 am-4am: 2.019, if the total amount of snowfall at 7am is 7.8 inches, to determine how much snow fell between 4 am-7am the following calculation must be performed:
7.8 - 2.019 = X
5.781 = X
Therefore, since the amount of snow accumulated at 7 am was 7.8 inches, the snowfall between 4 and 7 am was 5.781 inches.

gasoline will it need to
go 18 miles?
Math question.......
Answer:
m 6= 133 degrees
m 8= 133 degrees
Step-by-step explanation:
m 1= 47
so m 2 would be 133 degrees because that equals 180 degres and that is parallel with m 5 and m 6 so m 6=133
and m 1 and m 4 and m 5 and m 8 are the same
