Hey There! :)
To Solve for t.
Distribute the brackets.
Subtract 7t from both sides.
Factor out variable, t.
Divide both sides by h-7.
Hope this helps!

Answer:
Step-by-step explanation:
9x + 2y = 24 (A)
y = 6x + 19 ------ > y - 6x = 19 * (-2) -------> -2y + 6x = -38 (B)
(A) + (B)
15x = -14
x = -14/15
y = 6 * (-14/15) + 19 = -28/5 + 19 = 67/5
Hey!
--------------------------------------------------
10x = 10
To find the constant of proportionality just take the number and divide it by 1. 10x/1 = 10. The constant of proportionality can also be found by finding the slope of an expression or graph. In this case the slope is 10.
--------------------------------------------------
Thus, 10 is the constant of proportionality!

Answer:
BD is 3.75 units
Step-by-step explanation:
Given:
BA = 6 units
CA = 8 units
DC = 5 units
To Find:
BD = ?
Solution:
Triangle Angle Bisector Theorem.
An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.
I.e Here in Δ BAC,
AD is the Bisector of ∠ A
∴ 
Substituting th above given values in it we get
∴ 
∴ 
Therefore BD is 3.75 units
Answer:
Step-by-step explanation:
I will assume that the figure is a parallelogram.
2b = 28
b = 14
3y = 42°
y = 14°
a = 20
4x = 180-70-42 = 68
x = 17°
