x= -4 because 1.4 times -4=- 5.6 and 2.6 times -4=-10.4 and when we add to numbers postive or negative numbers it stays positive or negative depnding on the problem and 10.4 + 5.6 + 16 however becuase both were negative the answers stays negative making the answer _ 16 and it says 1.4x+2.6x=-16 so the correct answer is x= -4
Answer: 16 5/8
Step-by-step explanation:
3 1/2 = 7/2
4 3/4 = 19/4
7/2 * 19/4 = 133/8 or 16 5/8
Answer:
y = -2x + 12
Step-by-step explanation:
Step 1: find the slope
y = 1/2x + 5
The equation of the line is
y = mx + c
m - slope
m = 1/2
Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other
m = -2
Step 2 : using a point slope form
y - y1 = m( x - x1)
( 2 , 5)
x1 = 2
y1 = 5
y - 2 = -2( x - 5)
y - 2 = -2x + 10
y = -2x + 10 + 2
y = -2x + 12
The equation of the line is
y = -2x + 12
I dunno the answer so I just found another answer I found in here for this question:P
Sorry- it’s useless
Answer: C = - 71/3 or -23.6 or -23 2/3 All the same
Step-by-step explanation:
A)
Since 5 of the books are new, that means that the other books are used. So, there are 11-5=6. The ratio would be 5:6.
b)
The ratio is 6:11. You get the 6 from the above problem.
Hope this helps!
