Answer:
k=23
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
k-8-(15)=0
Step by step solution :
STEP
1
:
Solving a Single Variable Equation
1.1 Solve : k-23 = 0
Add 23 to both sides of the equation :
k = 23
One solution was found :
k = 23
(1,5) I think, because that’s where the points intersect
<span> 82+ 90+78+100 = 350
</span><span>Tim wants to have a test average of 90% on all of his 6 tests then
</span>90 x 6 = 540
540 - 350 = 190
<span> the average of Tim’s next two tests = 190 / 2 = 95
answer
</span><span>average of Tim’s next two tests must be 95</span>
Answer:
c =14.9 cm
Step-by-step explanation:
<C = 180 - (150 + 12)
<C = 180 - 162
<C = 18°
Law of sines:
sin (18) / c = sin(12) / 10
0.309 / c = 0.2079 / 10
c = 0.309 * 10 / 0.2079
c =14.9
