Answer:
D.
Step-by-step explanation:
Form an equation. 593 = 418 + 12.50d
The variable d represents how many days she needs to pet-sit for.
Use the subtraction property of equality by removing 418 from both sides.
593 - 418 = 418 - 418 + 12.50d
175 = 12.50d
You will need to divide both sides by 12.50 to get the variable by itself.
14 = d
You've gotten the answer now, 14.

Answer: The speed of the car is 45.3 miles per hour.
Step-by-Step Explanation: Let 'x' be the speed of the car.
60 × 2/3 = 120/3 = 40
30 × 1/5 = 151/5
151/5 /40 = x / 60
151 / 200 = x / 60
=> x = (151×60) / 200
=> x = 45.3
Answer:
The car was traveling at an average speed of 45.3 miles per hour.
Step-by-step explanation:
We need to figure out how many minutes are in 2/3 of a hour. If we divide 60 minutes by 3 we get 20 minutes, so 2/3 of 60 minutes is (20 minutes x 2) 40 minutes.
We now know that the car traveled 30.2 miles in 40 minutes. We want to know if it traveled for 60 minutes, what would the average speed be. The ratio will be the same, so we want to solve for x (miles):
30.2/40=x/60
We then cross multiply:
30.2x60=40(x)
1,812=40(x)
Divide each side by 40
1,812/40 = x
x=45.3

Two number cubes are rolled.
What is the probability that the first lands on an odd number and the second lands on an even number?
Enter you answer, as a fraction in simplified form, in the box.
Answer:
1/2
Step-by-step explanation:
if both cubes are 6 sided. Then for the first one the probability is 3/6. second is also 3/6. but we are looking for the probability of this outcome. we can add all of the sides to get 12. then we have 3 even numbers and 3 odd numbers. which added together is 6. we bow have 6/12, which is 1/2 simplified
A dilation with a scale factor of 1/3 is a reduction. A dilation with a scale factor of 2 is a reduction . which is true and which is false
Answer:
True: A dilation with a scale factor of 1/3 is a reduction.
False: A dilation with a scale factor of 2 is a reduction.
Step-by-step explanation:
A dilation with a scale factor between 0 and 1 is a reduction because the image will decrease in size.
On the other hand, a dilation with a scale factor greater than 1 is an enlargement, where the image increases in size.
So, the statement that a dilation with a 1/3 scale factor is a reduction is true.
The other statement is false, which says a dilation with a scale factor of 2 is a reduction.

Write an expressions for the missing dimension of each shaded figure and a multiplication expression for it's area
Answer:
alrighty then, x has to be 14, so x-3=11 which means the question mark would be 3. you can do the rest yourself, I believe in you!
Step-by-step explanation:
To solve this problem, we are required to write and expression to solve for the missing side in each figure.
Side of a SquareTo find the missing side of the square, we can simply write it as
[tex]15 = h + x\\x = (15 - h)m[/tex]
For the triangle, to find the missing side let's calculate the area of the triangle
[tex]area = \frac{1}{2} base * height\\area = \frac{1}{2} * 5 * 12\\area = 30m^2[/tex]
But for the length of the missing side, we can simply write it as
[tex]b = 10 + x\\x = (b - 10)m[/tex]
The expressions for the missing sides are;
x = (15- h)mx = (b - 10)mLearn more on area of a square and triangle here;

In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 80° angle and the 60° angle.
Write and solve an equation to determine the measure of angle x. (5 points)
Answer:
x = 40°Step-by-step explanation:
Straight angle is equal to 180°
Angle x, 60° and 80° form a straight angle.
Then we have following equation to solve for x:
x + 60° + 80° = 180°x + 140° = 180°x = 180° - 140°x = 40°True or false, the two expressions are equivalent.
3(4a - 2) and 12a - 6
Answer:
its true because 3(4a - 2) is 12a - 6
Answer:
True
Step-by-step explanation:
its true because 3(4a - 2) you would do 3 x 4a and instead of 4 - 2 you would change it to 4 + 2 after that you would do 3 x 4a = 4a + 2 which gives you
12a - 6
so yes they are equivalent
