Answer:
Step-by-step explanation:
13+(12-x)+14+(20-x)+x+(15-x)+8=74
solve for x
x=4
True. Both methods correctly verify the trig identity
Answer:
<em>A . 0.85 + (0.15 +(-3)) = -2</em>
<em>B . [(-3)+(-3)]+(-3) = - 9</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<em>Associative property with addition</em>
<em>(a+(b+c)) = (a+b) + c</em>
A)
Given 0.85 + (0.15 +(-3)) = (0.85 +0.15)+(-3)
= 1 - 3
= -2
B) Given [(-3)+(-3)]+(-3) = ( (-3)+[( -3)+(-3))]
= ( -3 +[-3-3]
= -3 -6
= -9
<u><em>Final answer:</em></u>-
<em>A . 0.85 + (0.15 +(-3)) = -2</em>
<em>B . [(-3)+(-3)]+(-3) = - 9</em>

Answer:

Step-by-step explanation:
Given
x ----- y
0.5. --- 0.8
1. --- 1.6
3.--- 4.8
25. --- 40
Required
Determine the constant of proportionality
This can be calculated using the following formula:
; Where r is the constant of proportionality;
Solve for r

When x = 0.5; y = 0.8


When x = 1; y =1.6


When x = 3; y = 4.8


When x = 25; y = 40


Notice that the value of r is constant throughout;
Hence:
