Solve the inequality-x/2 ≤ 1
Answers
Answer:
Step-by-step explanation:
Solve the inequality -x/2 ≤ 1. Let's eliminate the fraction first, by multiplying both sides by 2:
-x ≤ 2
We want to solve for +x, not for -x.
Therefore, divide both sides of this latest inequality by -1, remembering to reverse the direction of the inequality sign:
-x ≤ 2 → x ≥ -2

is paid an annual salary of $26,000. Find the Pat's weekly salary
Answers
Answer:500
Step-by-step explanation:26,000/52=500 i did $26,000 divided by 52 because there are 52 weeks in a year and it gave me 500 so that is how i got the answer
There are 52 weeks in a year, so the annual salary is 52 times the week salary.
So, we have
[tex]\dfrac{26000}{52} = 500[/tex]
which means that Pat makes 500$ a week
The total area of two rectangles can be represented by the expression (x)(3x+1) + (2x)(x+3). Which expression represents the total area of the two rectangles?
Answers
Answer:
The total area of the two rectangles is [tex](5x^{2} +7x)\ units^{2}[/tex]
Step-by-step explanation:
Area of rectangle 1
[tex](x)(3x+1)=(3x^{2} +x)\ units^{2}[/tex]
Area of rectangle 2
[tex](2x)(x+3)=(2x^{2} +6x)\ units^{2}[/tex]
therefore
The total area of the two rectangles is equal to
[tex](3x^{2} +x)\ units^{2}+(2x^{2} +6x)\ units^{2}=(5x^{2} +7x)\ units^{2}[/tex]
The correct choice is [tex]5x^{2} +7x[/tex]. By expanding and combining the terms, the total area of the two rectangles is represented by the expression found.
Let's first expand each term in the expression (x)(3x+1) + (2x)(x+3) to determine the total area of the two rectangles:
(x)(3x+1) = [tex]3x^{2} +x[/tex](2x)(x+3) = [tex]2x^{2} +6x[/tex]Now, add the two results together:
[tex]3x^{2}[/tex] + x + [tex]2x^{2}[/tex] + 6x = [tex]5x^{2} +7x[/tex]Therefore, the expression that represents the total area of the two rectangles is [tex]5x^{2} +7x\\[/tex] .

What size picture will result when a 5 in. • 7 in. Picture is reduced using an 80% setting?
Answers
A 5" * 7" image reduced by 20% in scale to 80% of the original size will be 4" * 5.6". Roughly the size of a large flash card.
When a 5 inch by 7 inch picture is reduced using an 80% setting, the new dimensions will be 4 inches by 5.6 inches.
To calculate the new size of a 5 inch by 7 inch picture when reduced by 80%, we simply multiply both dimensions by the reduction percentage. Hence, the width and the height of the picture will be reduced to 80% of their original size.
Original width: 5 inches
Original height: 7 inches
Reduction setting: 80% (or 0.8)
New width: 5 inches × 0.8 = 4 inches
New height: 7 inches × 0.8 = 5.6 inches
Therefore, the new dimensions of the picture will be 4 inches by 5.6 inches after an 80% reduction.
find the LCM of m^2 - 4m - 5 and m^2 + 8m + 7
Answers
Answer:
LCM=(m+1)(m-5)(m+7)
Step-by-step explanation:
Given expressions are [tex]m^2-4m-5[/tex] and [tex]m^2+8m+7[/tex].
To find the LCM, first we need to find factors of both expressions.
[tex]m^2-4m-5[/tex]
[tex]=m^2+1m-5m-5[/tex]
[tex]=m(m+1)-5(m+1)[/tex]
[tex]=(m+1)(m-5)[/tex]
Similarly factor other expression
[tex]m^2+8m+7[/tex]
[tex]=(m+1)(m+7)[/tex]
Common factor in both is (m+1)
bring down remaining non-common factors.
So LCM=(m+1)(m-5)(m+7)

Find the solution of this system of equations. 3x+7y=46 -3x-8y=50
Answers
The solution to the system of equations 3x + 7y = 46 and -3x - 8y = 50 is x = 239.333... and y = -96. This can be verified by plugging these values back into the original equations.
Explanation:To find the solution of this system of equations, we can use the method of adding the two equations together, as they are set up nicely for elimination:
3x + 7y = 46-3x - 8y = 50Add the two equations together:
3x + 7y - 3x - 8y = 46 + 50
0x - y = 96
y = -96
Substitute y = -96 back into one of the original equations, for example the first equation:
3x + 7(-96) = 46
3x - 672 = 46
3x = 46 + 672
3x = 718
x = 718 / 3
x = 239.333...
The solution to the system is x = 239.333... and y = -96. We can verify the solutions by substituting back into the original equations.

Write the following equation in slope intercept:
2x + 3y = 12
Answers
Y = mx + b
2x + 3y = 12
3y = -2x + 12
y = -2/3 + 4
Answer:
y = -2/3x +4
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
2x+3y = 12
We need to solve for y
Subtract 2x from each side
2x-2x+3y = -2x+12
3y = -2x+12
Divide by 3
3y/3 = -2/3 x +12/3
y = -2/3x +4
A recipe calls for 2/3 cup of flour for every 4 teaspoons of vanilla. How much vanilla should be used for every 1 cups of flour?
A. 1/6
B. 2 2/3
C. 4 2/3
D. 6
Please help and explain everything! Thanks!
Answers
Answer: For 1 cup of flour, there should be 6 teaspoons of vanilla.
Step-by-step explanation:
What I did is that I found what 1 ÷ 2/3 equals. To find that, I used the reciprocal so the new equation would be 1 × 3/2 which equals 3/2. So since 2/3 × 3/2 equals 1, we have to do the same to 4 teaspoons. 4 × 3/2 equals 6. Therefore, there should be 6 teaspoons of vanilla for every one cup of flour.

You run 5 miles in 1 hour. At this rate, how long will it take you to run a marathon (approximately 26 miles)?
I got 5 hours and 2 minutes and I'm not sure if I'm correct.
Answers
Answer:
5 hours 12 mins
Step-by-step explanation:
You run 5 miles in 1 hour.
5 miles = 1 hour
1 mile = 1 ÷ 5 = 0.2 hour
1 mile = 0.2 hour
26 miles = 0.2 x 26 = 5.2 hours
5.2 hours = 5 hours + (0.2 x 60) mins
5.2 hours = 5 hours 12 mins
If the speed is 5 miles per hour. Then the time taken to complete marathon of 26 miles will be 5 hours and 12 minutes.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
You run 5 miles in 1 hour.
Then the speed will be
Speed = 5/1
Speed = 5 miles per hour
Then the time taken to complete marathon of 26 miles will be
Time = Distance / Speed
Time = 26 / 5
Time = 5.2 hours
The time 5.2 hours can be written as 5 hours and 12 minutes.
More about the speed link is given below.
