Answer:
2x-10
Step-by-step explanation:
Multiply BOTH x and -5 by 2
S) This question is asking me to find the volume of the backpack.
O) Identify the facts: compartment one is 14x3x10, compartment two is 12x2x10, Julissa got a new backpack
Eliminate the unnecessary facts: Julissa got a new backpack
List the necessary facts: compartment one is 14x3x10, compartment two is 12x2x10
L) I chose Multiplication, I will multiply the measurements of compartment one, then multiply the measurements of compartment two and add them together to find the volume of the backpack.
V) I think the backpack will be at least 300 inches cubed.
(SOLVING PART)
Compartment one: 12 times 2 times 10 = 240
Compartment two: 14 times 3 times 10 = 420
420 + 240 = 660
E) Julissa’s backpack is 660 inches cubed.
I hope this helps
Answer:
$21.00
Step-by-step explanation:
1(x+3)+x=45
x+3+x=45
x+x=42
2x=42
x=21
I think it would be something like this: x-80 = (x*2)+12
Answer:
A
Step-by-step explanation:
The equation will be in the form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (2.5, 0) ← 2 points on the line
m =
= - 2
The line crosses the y- axis at (0, 5) ⇒ c = 5
y = - 2x + 5 or
y = 5 - 2x → A
