Answer:
16p + 6
Step-by-step explanation:
(12p + 9) + (4p - 3)
12p + 4p = 16p
9 + (-3) = 6
Answer: 16p + 6
Answer:
The value of the angles are 38° and 52° respectively
Let the acute angles be represented by a and b.
Based in the information given,
a = 2(b - 12)
a = 2b - 24.
Note that the angle in an acute angle equals to 90°.
Therefore,
a = 90 - b.
a = 2b - 24
Equate the equations together
90 - b = 2b - 24
2b + b = 90 + 24
3b = 114
b = 114/3
b = 38
Therefore, a will be:
= 90° - 38° = 52°
The value of the angles are 38° and 52° respectively.
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
The equation of quantities in direct variation is
y = kx ← k is the constant of variation
Given
7y = - x ( divide both sides by 7 )
y = - x ← in direct variation form
with k = -
Answer:
x-intercept: (8, 0)
y-intercept: (0, -4)
Step-by-step explanation:
Answer – A letter
In algebraic equations, a variable refers to an unknown or changeable number. Typically, all the letters in the alphabet are used to represent variables in algebra. Letters from the Greek alphabet are also used in some advanced algebra. Therefore, in algebra, we use a letter to represent a variable.
