Since the angles are Corresponding Angles, we can set the unknown value equal to each other then solve for x.

20-8x = 30 - 16x Original Equation
20 = 30 - 8x Moving x terms to one side by addition
-10 = -8x Subtraction Prop of Equality
x = 1.25 Division Prop of Equality

Two trains, train a and train , weigh a total of 466 tons. Train A is heavier than train b. The difference of there weights is 3

AlexFokin [52]

Answer: A = 396 tons

B = 70 tons

Step-by-step explanation:

From the question,

Weight of A + Weight of B = 466

Weight of A - Weight of B = 326

A + B = 466 ......... i

A - B = 326 ..........ii

Subtract equation ii from I

2B = 140

B = 140/2

B = 70 tons

A = 466 - 70

A = 396 tons

y intercept=b=-3

Take two points

(-3,0)
(0,-3)

$\\ \sf\longmapsto m=\dfrac{-3-0}{0+3}=\dfrac{-3}{3}=-1$

Equation of line in slope intercept form

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto y=-x-3$

Step-by-step explanation:

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them.
