Answer:
The three angles are 40°, 75°, 65°
Step-by-step explanation:
Assume that the first angle is x
∵ The second angle is 35° more than the first angle
∴ The second angle is x + 35
∵ The third angle is 25° more than the first angle
∴ The third angle is x + 25
∵ The sum of the angles of a triangle is 180°
→ Add the three angles and equate the sum by 180°
∵ x + x + 35 + x + 25 = 180
→ Add the like terms in the left side
∴ (x + x + x) + (35 + 25) = 180
∴ 3x + 60 = 180
→ Subtract 60 from both sides
∴ 3x + 60 - 60 = 180 - 60
∴ 3x = 120
→ Divide both sides by 3 to find x
∴ x = 40
→ Find each angle by substitute x by 40
∵ First angle = x
∴ The first angle = 40°
∵ Second angle = x + 35
∴ The second angle = 40 + 35 = 75°
∵ Second angle = x + 35
∴ The third angle = 40 + 25 = 65°
∴ The three angles are 40°, 75°, 65°

I need help please someone help
Answer:
x= 40 degrees
Step-by-step explanation:
The two angles inside must add up to 126, since the missing unknown angle is supplementary to 126 (where they add up to 180 degrees).
Thus
x + (2x+6) = 126
3x + 6 = 126
3x = 120
x = 40

Half the area of the rectangle shown is 24 square inches. Write and solve an equation to find the value
of x.
6 in.
(x + 2) in
Equation:
X=
2
Answer:
Step-by-step explanation:
Half the area of the rectangle shown is 24 square inches. Then value of x is 6
What is Area of Rectangle?The area of Rectangle is length times of width.
Area = length x width.
24 = (x + 2)(x - 3) = x² - x - 6
x² - x - 30 = 0
(x + 5)(x - 6) = 0
We can eliminate the root x = - 5 because dimensions cannot be negative. So, the only valid answer is x = 6
The length = x + 2 = 6 + 2 = 8 in.
The width = x - 3 = 6 - 3 = 3 in
Hence, the value of x is 6.

Which line shows the graph of y = 4x - 5 reflected over the y-axis?
y = 4x + 5
y = 4x - 5
Y=2x-5
y = -2x + 5
Answer:
The line y = -4x - 5 shows the reflection over the y-axis.
From the attached graph, the blue line i.e. y = -4x-5 represents the reflection over the y-axis.
Step-by-step explanation:
When we reflect a line function over the y-axis, all we need is to negate the x-coordinate or value of 'x', while y-coordinate or y-value remains the same.
Given the function
y = 4x-5
replace x with -x
y = 4(-x) - 5
y = -4x - 5
Thus, the line y = -4x - 5 shows the reflection over the y-axis.
From the attached graph, the blue line i.e. y = -4x-5 represents the reflection over the y-axis.
From the graph, it is clear that that that x-coordinate of y = 4x-5 is negated.

One fifth of a number plus three times the number is equal to 42 Moré than twice the number. Whats the number
Answer:
35
Step-by-step explanation:
Let number = x
(1/5 of x) + (3 * x) = 42 + (2 * x)
x/5 + 3x = 42 + 2x
1/5x + 3x - 2x = 42
1 1/5x = 42
6/5 x = 42
x = 42 ÷ 6/5
x = 42 * 5/6
x = 210 / 6
x = 35
The number is 35

Answer:
t_10 = 59049 x^25
Step-by-step explanation:
a = 3x^7

Evan’s family drove to a theme park for vacation.
They drove the same speed throughout the trip.
The first day, they drove 300 miles in 6 hours.
The second day, they drove 250 miles in 5 hours.
The third day, they arrived at the park after driving for 3 hours.
How many miles did they drive on the third day?
- First: Calculate how many miles the family is driving in ONE hour.
There are two equations you can form to solve this.
300 / 6 = mph (miles per hour)
250 / 5 = mph (miles per hour)
300 / 6 = 50
250 / 5 = 50
They are driving 50mph. Now, you need to find out how many miles they drive in three hours.
50 * 3 = 150
Evan's family drove 150 miles on the third day.
Answer:
150 miles
Step-by-step explanation:
The first day, they drove 300 miles in 6 hours so divide 6 by 300. 300 divided by 6 equals fifty. On the third day, they drove half the amount of time, so it would be half the amount of miles because they drove the same speed throughout the trip.
300/2 so the answer to the question is 150 miles.
