Answer:
(1.7x10^13)+(0.8x10^13)
=(1.7x1e+13)+(0.8x1e+13)
=1.7e+13+0.8e+13
=2.5e+13
in actual number it would be 25,000,000,000,000
Step-by-step explanation:
Answer:
The correct answer here is 2/3
Step-by-step explanation:
That is because 7 doubled is 14 and 7 multiplied by 3 is 21.
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (4, - 1) and (x₂, y₂ ) = (- 2, 3)
m =
=
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, 3) , then
3 =
+ c ⇒ c = 3 -
= 
y = -
x +
← in slope- intercept form
Multiply through by 3 to clear the fractions
3y = - 2x + 5 ( add 2x to both sides )
2x + 3y = 5 ( subtract 5 from both sides )
2x + 3y - 5 = 0 ← in general form
X = 7 for the question in the picture
Answer:
28
Step-by-step explanation:
Hi! So what we're gonna want to do here is set up a system of equations. Lets say x = regular baskets and y = deluxe baskets. You would set up the system like this:
28x + 24y = 1,188
28x + 13y = 836
So since the number before the x is the same in both equations, we are going to want to cancel that out.
28x + 24y = 1,188
-1(28x + 13y = 836)
----------------
28x + 24y = 1,188
-28x - 13y = -836
Add the two equations together! There will be no x value :)
11y = 352
y = 32... The deluxe basket is going to cost $32
Put the y value into one of the equations to solve for x.
28x + 13(32) = 836
28x + 416 = 836
28x = 420
x = 15... The regular basket will cost $15
Hope this helps!
