Step-by-step explanation:
The equation is
x×2=285-x
3x=285
x=95
Answer:
x = 75°
Step-by-step explanation:
There are many Circle Geometry Rules. We will be using the following:
The angle at the centre of the circle is twice the angle at the circumference.
x = the angle opposite 285 - x.
This means that 360 - (285 - x) = 2x
360 - 285 + x = 2x
75 + x = 2x
We can simplify this by taking away x from both sides.
75 = x
We can check this by substituting x into the orginal equation.
360 - (285 - x) = 2x
360 - (285 - 75) = 2 * 75
360 - 210 = 2 * 75
150 = 2*75
150 = 150

Answers
Answer:
She practiced a total of 64.5 hours
Step-by-step explanation:
Here, we need to know the number of hours practiced on both per day
Mathematically, that will be;
0.75 + 1.4 = 2.15 hours per day
So in 30 days ; the total number of hours will be
30 * 2.15 = 64.5 hours

At Algorithms Pizza they have the exponential pizza, which is a 24-inch cheese pizza that costs $17.50. Each topping for the pizza costs $2.35. If Connor ordered the exponential pizza and was charged $29.25, how many toppings were on his pizza?
Answers
Answer:
There were 5 toppings on his pizza.
Step-by-step explanation:
From the information given, you can say that the total cost of the pizza would be equal to the cost of the 24-inch cheese pizza plus the result of multiplying the cost of each topping for the number of toppings, which can be expressed as:
c=17.50+2.35x, where:
c is the total cost
x is the number of toppings
Now, you can replace the total cost with $29.25 and solve for x:
29.25=17.50+2.35x
29.25-17.50=2.35x
11.75=2.35x
x=11.75/2.35
x=5
According to this, the answer is that there were 5 toppings on his pizza.
Are you study of a population of 1200 frogs you feel that sold out of every 180 frogs in the population has spots on the back based on the results of the other study how many frogs in the population do not have spots in the back
Answers
Answer: 1,120 frogs
Step-by-step explanation:
If 12 out of every 180 frogs in the population have spots on their backs, the number that do not are;
= 180 - 12
= 168 frogs
168 frogs out of every 180 do not have spots. Out of 1,200 that would be;
= 168/180 * 1,200
= 1,120 frogs

The graph below shows a system of equations:
The x-coordinate of the solution to the system of equations is
Answers
Answer:
solution is (-2, 2) so x-coordinate of solution is -2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
First, we have to write down both equations.
y = x + 4
3y = -2x + 2
Now we already have an equation that we can plug into the other equation.
= 3(x + 4) = -2x + 2
= 3x + 12 = -2x + 2
= 5x + 12 = 2
= 5x = -10
x = -2
Now we know that x = -2, and the question asks for the x-coordinate, which is -2.
Dimas is playing a game that uses a number cube. The sides of the cube are labeled from 1 to 6. Dimas wants to roll a 2 or 3. He rolls the number cube one time
Answers
Answer:
B. 1/3
Step-by-step explanation:
The total number of sides in the cube are 6 (1,2,3,4,5,6). If Dimas only wants to roll either a 2 or 3 then that would mean that he has 2 chances out of the total 6 probable outcomes to roll one of those numbers. Therefore, in order to find the probability of this happening in a single roll we need to divide the number of times that his two choices appear on the dice by the total number of sides the dice has, like so...
2 / 6 = x
