Answer: 63.75 or 225/4
I just did it on an IT Inspired inspired Calculator to solve for X and 63.75
Step-by-step explanation:
8(x - 7) = 454
x - 7 = 454/8
x - 7 = 57
x = 57 + 7
x = 64
Answer: 1.2
Why? Here:
3.6 is also known as 36/100
So, 36/100 ÷ 3/1
36/100 x 1/3 ( transposing because of divide)
36 comes in 3 table so, 36÷3 is 12
12/100 x 1
12/100 also known as 1.2
Answer:
y=5
Step-by-step explanation:
multiply the -4 with 2y
combine the -8y with the positive 11y getting 3y
divide the 3 to get y by itself
y=5
We can find the right angle of the triangle by finding the slope of the sides .
Any right angle makes an angle of 90 degrees and the lines are perpendicular .
For perpendicular lines product of slopes is -1.
In other words the slopes have opposite signs and are reciprocal .
Let us find the slopes of AB,BC,CA.
Slope of two points can be found by the difference in y values divided by different in x values
Slope of AB=
Slope of BC=
Slope of CA=
The slopes of AB and CA are reciprocal of each other with opposite signs or we can say their product is -1 so they are perpendicular.
Angle A is the common angle to these sides so we say angle A is the right angle
It is to be noted that 171 divided by 9 equals 19. This is a division prompt.
19
___________
9 | 171

Therefore, 171 divided by 9 equals 19.
Note that division is a mathematical operation that involves dividing a number (the dividend) by another number (the divisor) to find the quotient.
The quotient represents the result or answer obtained from dividing the dividend into equal parts determined by the divisor.

Answer:
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point on a line
The formula of a slope:
We have two points (-4, 3) and (3, -4).
Substitute:
Put the value of a slope and the coordiantes of the point (-4, 3) or (3, -4) to the equation of a line:
for (-4, 3)
for (3, -4)
