-3(k-5)=27 and the way to show your work on this two step equation
Answer:
k = -4
Step-by-step explanation:
Applying the Distributive Property of Multiplication, we get
-3k + 15 = 27, which simplifies to -3k = 12. Then k must be
k = -12/3, or k = -4
Why is -55.1 a rational number?
Use the Distributive Property to simplify the expression. 11(b−3)
Answer: 11b-33

A group of friends goes out to dinner. The total bill, without tax, is $63. If tax on the meal is 6% and if an 18% tip is left on the $63 total billwhat is the total amount paid?
Answer: $78.12
Step-by-step explanation:
First find the tip to be paid on the pretax amount:
= 63 * 18%
= $11.34
Then find the tax to be paid:
= 63 * 6%
= $3.78
Add the tip and the tax to the pretax bill:
= 63 + 11.34 + 3.78
= $78.12

Martha sells custom painted square canvases. She determined that the amount of tissue paper she'll need to wrap each canvas can be represented by
y= x^2 + 2x + 1, where y is the total square inches of tissue paper and x is the side length of the canvas in inches. Write and solve an equation to determine the side length of the canvas is Martha needs 49 square inches of tissue paper.
Given:
The equation is
[tex]y=x^2+2x+1[/tex]
where y is the total square inches of tissue paper and x is the side length of the canvas in inches.
To find:
The side length of the canvas is Martha needs 49 square inches of tissue paper.
Solution:
We have,
[tex]y=x^2+2x+1[/tex]
Putting y=49, we get
[tex]49=x^2+2x+1[/tex]
[tex]0=x^2+2x+1-49[/tex]
[tex]0=x^2+2x-48[/tex]
Splitting the middle term, we get
[tex]0=x^2+8x-6x-48[/tex]
[tex]0=x(x+8)-6(x+8)[/tex]
[tex]0=(x+8)(x-6)[/tex]
Using zero product property, we get
[tex]x+8=0[/tex] and [tex]x-6=0[/tex]
[tex]x=-8[/tex] and [tex]x=6[/tex]
Side length cannot be negative. So, only possible value of x is 6.
Therefore, Martha needs 6 inches side length of the canvas for 49 square inches of tissue paper.

Answer:
Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother. If that X chromosome has the gene for red-green color blindness (instead of a normal X chromosome), they will have red-green color blindness.

#7: Five containers, each weighing the same amount, were placed on a 30-pound
platform. The platform and containers were lifted onto a train car. The maximum weight
that can be lifted by the cable is 780 pounds. Which inequality represents the possible
weight of one container, x, on the platform?
A. x < 130
B. x < 150
C. x < 156
D. x < 162
Answer:
Option (B)
Step-by-step explanation:
Let the weight of one container = x pounds
Therefore, weight of 5 containers = 5x pounds
Weight of the platform = 30 pounds
Total weight of the platform and containers = (5x + 30) pounds
If the maximum weight that can be lifted by the cable = 780 pounds
Inequality representing this situation will be,
(5x + 30) < 780
5x < 780 - 30
5x < 750
x < 150
Therefore, Option (B) is the answer.

Answer:
7 rides
Step-by-step explanation:
38 - 10 (entrance fee) = $28 to spend on rides
if it's $4 per ride, we can divide the remaining money ($28) by the cost of each ride ($4)
28 / 4 = 7
Therefore, she can ride 7 rides

measure of one angle of a parallelogram is 40 degree more than the other.find the angles.
Answer:
Below in bold.
Step-by-step explanation:
If one angle is x then the other is x+40 degrees.
These angles sum to 180 as we have a parallelogram, so
x + x + 40 = 180
2x = 140
x = 70.
So the angles are 70 and 110
110 ,70,110,70 are the angles
EXPLANATION:Let's say that angle 1 is x
This means another angle will be x - 40
The sum of all 4 angles is 360
The sum of two angles 180
x + x - 40 = 180
2x = 220
x = 110
180 - 110 = 70 meaning that each side has an angle measuring 110 degrees and an angle measuring 70. And 110 - 70 = 40 like you mentioned

Answer:
y<13/2
Step-by-step explanation:
5y+4<3y+17
5y-3y<17-4
2y<13
y<13/2
Answer:
y < [tex]\frac{13}{2}[/tex]
Step-by-step explanation:
Given
5y + 4 < 3y + 17 ( subtract 3y from both sides )
2y + 4 < 17 ( subtract 4 from both sides )
2y < 13 ( divide both sides by 2 )
y < [tex]\frac{13}{2}[/tex]

Area:
Circumference:
X Х
?
Answer:
Step-by-step explanation:
Circumference
C = 2*pi * r
pi = 3.14
r = d / 2
r = 8/2
r = 4 feet
C = 3.14 * 2 * 4
C = 18.84 feet.
Area
pi = 3.14
r = d/2
r = 8/2
r = 4
Area = 3.14 * 4^2
Area = 3.14 * 16
Area = 50.24 ft^2

The ratio of cats to dogs was 3 to 7. If there were 300 cats and dogs in all, how many were cats?
Answer:
700
Step-by-step explanation:
The ratio of cats to dogs was 3:7
Divide 300 by 3
=100
multiply 100 and 7
=700
Step-by-step explanation:
let common ratio be x
3x + 7x = 300
10 x = 300
x = 300/10= 30
there common ratio x is 30
3 x 30 =90 cats
7 x 30 = 210 dogs
Lukas collected data on years of employment and the annual salaries of the salespeople at Company Z. He made a scatter plot and drew a trend line that approximated the line of best fit for the data, as shown below. What is the slope of the trend line that Lukas drew?
Answer:
The slope is 2500
Step-by-step explanation:
Given
See attachment for scatter plot
Required
Determine the slope of the scatter plot
From the plot, we can pick the following 2 points:
[tex](x_1,y_1) = (9,55000)\\[/tex]
[tex](x_2,y_2) = (3,40000)[/tex]
The slope (m) is then calculated as:
[tex]m = \frac{\triangle y}{\triangle x}[/tex]
This gives:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{40000-55000}{3-9}[/tex]
[tex]m = \frac{-15000}{-6}[/tex]
[tex]m = \frac{15000}{6}[/tex]
[tex]m = 2500[/tex]
The slope is 2500
