Answer:
In order to subtract a whole number from a fraction, you first have to turn the hole number into a mixed fraction.
Step-by-step explanation:
Say your fraction was 2/3 and your whole number was 5.
They have to have like denominators
5/1 - 2/3 = 15/3 - 2/3
15/3 - 2/3 = 13/3
13/3 = 4 1/3
It's easier to work with problems such as –2.1x + 3.7 -5 + 4.9x when we rearrange the like terms vertically:
–2.1x + 3.7 -5 + 4.9x
becomes
–2.1x + 3.7
+4.9x -5

2.8x - 1.3 (answer)
Answer:
y = 7x - 10
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (1, - 3)
m = 
= 
= 7, thus
y = 7x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 4), then
4 = 14 + c ⇒ c = 4 - 14 = - 10
y = 7x - 10 ← equation of line
Answer:
x = 17
Step-by-step explanation:
The two angles with measures form a linear pair and are supplementary.
The measures of supplementary angles has a sum of 180°.
If you add the two given measures, the sum must equal 180°.
4x + 2 + 110 = 180
4x + 112 = 180
4x = 68
x = 68/4
x = 17
Well it sounds like you are doing volume so it is length time winth time high so times all the fraction
