Answer:
x = 3.6
Step-by-step explanation:
1 (4) = 4
0.9 (4) = 3.6
x = 3.6
There is a sequence... adding 0.9 to each side (at different lengths).
Answer:
there was 3 pounds of raisins and 4 pounds peanuts.
Step-by-step explanation:

Answer:
speed is 240 miles per hour
Step-by-step explanation:
.75 is the answer because it looks like division
Answer:
y = 2x - 1
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 ) = A(4, 7) and (x₂, y₂ ) = B(2,3)
m =
=
= 2 , thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 2x - 1 ← equation of line
