Simplify by adding 13 and 9.
21 = 21, so 9 is a solution to the equation.
22 Not-equals 21, so 9 is not a solution to the equation.
Answer:
Substitute 9 for the variable h.Simplify by adding 13 and 9.22 Not-equals 21, so 9 is not a solution to the equation.Step-by-step explanation:
13 + h = 21 for h = 9
1. Substitute 9 for the variable h.
Correct, because the question already giving the value that h = 9.
2. Substitute 21 for the variable h.
False, because in the question it states that h is 9, not 21.
3. Simplify by adding 13 and 21.
False, because they are in different sides.
4. Simplify by adding 13 and 9.
True, the question giving that h is 9. In the left sides, it's 13 + h, by adding 13 and 9, we will get the answer for the left side.
5. 21 = 21, so 9 is a solution to the equation.
False, because in the left side is 13 + h = 13 + 9 = 22.
6. 22 Not-equals 21, so 9 is not a solution to the equation.
True, see the explanation in 5.
Answer:
Substitute 9 for the variable h.
Simplify by adding 13 and 9.
22 Not-equals 21, so 9 is not a solution to the equation.

b = 55 alternate angles
c=a=125 alternate angles
e =125. alternate angles
f=b=55
h=f=55 alternate angles
Step-by-step explanation:
(a) < a = 180-55= 125
(b) < b = 180- 125= 55
(c) < c = 189- 55 = 135
(d) < e = 125
(e) < f = 180-125= 55
(f) < h = 55

Waheed's father is twelve years older than his mother. The sum of their ages is 76 years old. How old is Weheed's father
Answer:
32
Step-by-step explanation:
Let, the age of father and mother be x and y respectively. then,
According to question,
x + y = 76.........(i)
x= y + 12...............(ii)
Now,
x + y = 76
or, ( y + 12) + y = 76
or, y + 12 + y = 76
or, 2y = 76 – 12
or, 2y = 64
or, y = 64/2
.
. . y = 32

Write the equation of the line that passes through the points (3,-3) and (3,8). Put
your answer in fully simplified point-slope form, unless it is a vertical or horizontal
line.
The equation of the line is the vertical line x = 3.
The gradient of the lineThe gradient of the line between two points (x₁, y₁) and (x₂, y₂) is m = (y₂ - y₁)/(x₂ - x₁).
Since the line passes through the points (3,-3) and (3,8),
(x₁, y₁) = (3,-3) and (x₂, y₂) = (3,8).So, substituting the values of the variables into the equation, we have
m = (y₂ - y₁)/(x₂ - x₁).
m = (8 - (-3))/(3 - 3).
m = (8 + 3)/0
m = 11/0
m = +∞
Equation of the line in point-slope form
The equation of the line passing through the point (x₁, y₁) in point-slope form is given by
y - y₁ = m(x - x₁) where
m = gradient = +∞ and (x₁, y₁) = (3, -3)So, substituting the values of the variables into the equation, we have
y - y₁ = m(x - x₁)
y - (-3) = +∞(x - 3)
y + 3 = +∞(x - 3)
y + 3/+∞ = (x - 3)
0 = x - 3
x = 3
So, the equation of the line is the vertical line x = 3.

Find the difference between
and
4/9 and -5/9
Answer:
1
Step-by-step explanation:
4/9 and -5/9 are 1 apart. This is because one of the numbers is positive and the other is negative, you have to make the negative number positive and add the two positive numbers together. In this case, 4/9+5/9=9/9. 9/9 is equivalent to 1. So, 4/9 and -5/9 are 1 apart.
Hope the explanation and answer helps!
Answer: -5/9 is negative, 4/9 is positive. The Difference when you subtract =1
Step-by-step explanation:
4/9 - -5/9 = 4/9 +5/9 = 1
