What is the solution to the equation
2/3x+1/6=1
Answer:
x = 5/4
Step-by-step explanation:
We can solve for x by isolating it from the other numbers. Move everything else over to the other side in reverse BEDMAS order.
[tex]\frac{2}{3}x + \frac{1}{6} = 1[/tex]
[tex]\frac{4}{6}x + \frac{1}{6} = 1[/tex] Give the fractions common denominators
[tex]\frac{4}{6}x + \frac{1}{6} - \frac{1}{6} = 1 - \frac{1}{6}[/tex] Subtract 1/6 from both sides
[tex]\frac{4}{6}x = 1 - \frac{1}{6}[/tex] 1/6 is cancelled out on the left side
[tex]\frac{4}{6}x = \frac{5}{6}[/tex] Simplify the right side
[tex]\frac{\frac{4}{6}x}{4/6} = \frac{\frac{5}{6}}{4/6}[/tex] Divide both sides by 4/6
[tex]\frac{4}{6}x X\frac{6}{4} = \frac{5}{6} X\frac{6}{4}[/tex] Dividing is like multiplying by the flipped second fraction on both sides
[tex]\frac{24}{24}x = \frac{30}{24} [/tex] Simplify. 24/24 = 1 and reduce 30/24
[tex]x = \frac{5}{4} [/tex] Final answer

Gwen borrows $300 from her parents to buy a bike. She agrees to pay them back plus 3% simple interest over one year. Write an equation to represent the total amount Gwen will owe her parents. What is the total amount of money Gwen will owe her parents?
Answer:
$309
Step-by-step explanation:
Use the formula for simple interest: [tex]A = P(1+rt)[/tex]
A represents total amount, unknown in this case.
P represents principal, or starting amount, 300 in this case.
r represents the interest rate in decimal form, 3% in this case, or 0.03.
t represents time, usually in years, 1 in this case.
[tex]A = P(1+rt)[/tex]
[tex]A = 300(1+(0.03)(1))[/tex]
[tex]A = 300(1.03)[/tex]
[tex]A = 309[/tex]
Gwen will owe $309.
9.6.6. The pawn shop business model. On April 9, 2011 The New York Times reported on a pawn shop that opened in an ex-Blockbuster store: The borrowers are given 60 days to pay back the loan, and La Familia charges a 20 percent interest rate per month. (So for a $100 loan, the borrower would need to pay back $140 after 60 days.) a. Explain why 20% interest per month on a $100 loan for two months would actually require repayment of a little more than $140. b. What is the annual interest rate when this business lends money?

Answer:0.13
Step-by-step explanation:i think
The cost of each apple is given by the rate. Then the cost of each apple will be $0.13 per apple.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

what’s the x coordinate of point p?
Answer:
The x-coordinate of point P is 6
Step-by-step explanation:
we have
A (2,3) and B (8,0)
we know that
Point P portions the segment AB in the ratio 2 to 1
so
[tex]AP=\frac{2}{3} AB[/tex]
and
[tex]AP_x=\frac{2}{3} AB_x[/tex]
where
AP_x represent the distance between the points A and P in the x-coordinates
AB_x represent the distance between the points A and B in the x-coordinates
[tex]AB_x=8-2=6\ units[/tex]
[tex]AP_x=\frac{2}{3} (6)=4\ units[/tex]

Answer:
Emma was right to say that both packages are close to 2 pounds.
If we round-off the weights of both to the nearest whole number we would get 2 pounds on both. We look at the the difference of both from 2 pounds we get the following:
2.36 - 2.0 = 0.36
2.09 - 2.0 = 0.09
The smaller the difference the closer it is to the base value. So we can say that the closest one is 2.0 pounds is the package that weighs 2.09 pounds.
Find the x- and y-intercepts for the linear equation.
– 3x + 5y = 15
Answer:
x-intercept: (-5,0)
y-intercept: (0,3)
Step-by-step explanation:
y-intercept: when x = 0
-3(0) + 5y = 15
5y = 15
y = 3
x-intercept: when y = 0
-3x + 5(0) = 15
-3x = 15
x = -5
Answer:
Step-by-step explanation:
To find the x-intercept of – 3x + 5y = 15, let y = 0 and solve the remaining equation for x: – 3x + 5(0) = 15
Then -3x = 15, and x = -5. Thus, the x-intercept is (-5, 0).
to find the y-intercept of – 3x + 5y = 15, set x = 0 and solve the remaining equation for y: 5y = 15, so that y = 3. The y-intercept is (0, 3).

A student answered three questions on a 40-percent test incorrectly. What percent did the student answer correctly
Answer:
The percentage of questions correctly answered by the student was 92.5%
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Number of questions incorrectly answered by the student = 3
Number of questions on the test = 40
2. What percentage did the student answer correctly?
Number of questions correctly answered by the student = Number of questions on the test - Number of questions incorrectly answered by the student
Replacing with the real values:
Number of questions correctly answered by the student = 40 - 3
Number of questions correctly answered by the student = 37
Now, let's calculate the percentage:
Percentage = Number of questions correctly answered by the student /Number of questions on the test * 100
Percentage = 37 /40 * 100
Percentage = 0.925 * 100
Percentage = 92.5%

A triangle has two angles measuring 69 and 77. Determine the measure of the third angle b
Answer:
[tex]m\angle B=34\°[/tex]
Step-by-step explanation:
Given measures of 2 angles of a triangle :
m∠A = 69°
m∠C = 79°
Find m∠B.
We know that sum of angles of a triangle =180°
So, we have
[tex]m\angle A+m\angle B+m\angle C=180\°[/tex]
Substituting the vales of m∠A = 69° and m∠C = 79°
[tex]69\°+m\angle B+77\°=180\°[/tex]
Adding like terms.
[tex]m\angle B+146\°=180\°[/tex]
Subtracting both sides by 146°.
[tex]m\angle B+146\°-146\°=180\°-146\°[/tex]
∴ [tex]m\angle B=34\°[/tex] (Answer)

Jeanne is helping her dad with his
stueco business for the summer. Since Jeanne
has studied surface area in school, she does
some estimates for her dad's business,
For the garage at the right, they plan to stucco
the walls. They will not stucco the roof, car door,
side door, or window. The car door measures
5 m by 2.3 m, the side door measures 2.1 m by
0.9 m, and the window measures I m by 0.7 m.
Determine the surface area to be covered with stucco to the nearest square metre,
The surface area to be covered with stucco is 25.91 square metres.
Explanation:To find the surface area to be covered with stucco, we need to calculate the area of each wall and subtract the areas of the car door, side door, and window. The garage has four walls, so we will calculate the area of each wall and add them together. The area of each wall is the product of its length and height. Once we have the total area of the walls, we can subtract the areas of the car door, side door, and window to determine the final surface area to be covered with stucco.
Wall 1: 5 m * 2 m = 10 m²
Wall 2: 5 m * 2 m = 10 m²
Wall 3: 5 m * 2 m = 10 m²
Wall 4: 5 m * 2 m = 10 m²
Total area of walls: 10 m² + 10 m² + 10 m² + 10 m² = 40 m²
Area of car door: 5 m * 2.3 m = 11.5 m²
Area of side door: 2.1 m * 0.9 m = 1.89 m²
Area of window: 1 m * 0.7 m = 0.7 m²
Final surface area to be covered with stucco: 40 m² - 11.5 m² - 1.89 m² - 0.7 m² = <<25.91=25.91>>25.91 m² (rounded to the nearest square metre).

Learn more : https://brainly.com/question/13218948
Final answer:
Mindy saved $90 over 6 weeks, suggesting a constant rate of saving $15 per week. The proportional relationship between her total savings (y) and the number of weeks (x) is y = 15x.
Explanation:
Mindy started with $0 and after six weeks had $90. To find the proportional relationship between the money saved and the number of weeks, we assume that she saves the same amount every week. Since we know the total savings and the total time, we can divide the total savings by the number of weeks to find the constant rate.
Mindy's weekly saving rate would be:
Calculate the total amount saved: $90.
Divide the total amount by the number of weeks: $90 ÷ 6 weeks.
The result is $15 per week.
Therefore, the constant rate of saving is $15 per week. The proportional relationship can be represented as y = 15x, where y represents the total amount saved and x represents the number of weeks.
