Answer:
- equation: 1/2(s +8) = 20
- Mark began with 32 boxes
Step-by-step explanation:
Let s represent the number Mark started with. After buying 8 more, he then had s+8. After the fire, he had ...
(1/2)(s +8) = 20
This equation can be solved by multiplying by 2, then subtracting 8.
s +8 = 40
s = 32
Mark began with 32 boxes.
Hi, there.
______
Does an isosceles triangle have two sides of equal length?
Let's start by defining an isosceles triangle.
It's a triangle which has <em>two sides of equal length</em>; the third side, the base, is the shortest side.
Therefore, an isosceles triangle DOES have two sides of equal length.
Hope the answer - and explanation - made sense,
happy studying!!!
Answer:
D. y = 5/4x + 2 1/4
Step-by-step explanation:
The equation of the line is
y = mx + c
Step 1: find the slope
( 3 , 6) ( -1 , 1)
m = y2 - y1 / x2 - x1
m - is the slope of the line
( y1 , y2) - are point on the line
( x1, x2) - are point on the line
x1 = 3
y1 = 6
x2 = -1
y2 = 1
Inserting into the formula
m = y2 - y1 / x2 - x1
m = 1 - 6 / -1 - 3
m = -5/-4
Minus cancels minus
= 5/4
Step 2: substitute m into the equation of the line
y = mx + c
y = 5/4x + c
Step 3: sub any of the two points given into the equation
Let's pick ( 3 , 6)
x - 3
y - 6
y = 5/4x + c.
6 = 5/4(3) + c
6 = 5 * 3 / 4 + c
6 = 15/4 + c
c = 6 - 15/4
LCM = 4
c = 24 - 16 / 4
c = 9/4
c = 2 1/4
Step 4: sub c into the equation
y = 5/4x + c
y = 5/4x + 2 1/4
The equation of the line is
y = 5/4x + 2 1/4
