Answer:
The percentage increase equation is:
Percentage Increase = [ (Final Value - Starting Value) / |Starting Value| ] × 100
The percentage increase = 11.97%
Step-by-step explanation:
Given
Starting Value = 376
Final Value = 421
To determine
Percentage Increase =?
The percentage increase equation:
Percentage Increase = [ (Final Value - Starting Value) / |Starting Value| ] × 100
= [(421 - 376) / (376)] × 100
= [45 / 376] × 100
= 11.97%
Therefore, the percentage increase = 11.97%
3x^6+4x^5-3= 0
Because math equals equation
W+y=25 and 9.95w+11.5y=276.65
solve for w in equation one:
w+y=25
w=25-y
then substitute w in equation two and solve for y:
9.95w+11.5y=276.65
9.95(25-y)+11.5y=276.65
1.55y+248.75=276.65
1.55y+248.75-248.75=276.65-248.75
1.55y=27.9
1.55y/1.55=27.9/1.55
y=27.9/1.55=18
y=18
then substitute y=18 into the first equation to solve for x:
w+y=25
rewrite as w=25-y y=18
w=25-18
w=7
then are answer is w=7 and y=18
Answer:
y=
x=
Step-by-step explanation:
7x+4+12x+24=180
19x+28=180
19x=180-28
19x=152°
19x/19=152/19
x=8
y=7x+4
y=7*8+4
y=60°
Answer D.
Explanation:
7(1-k) to solve that you have to multiply 7 for 1 and for -k
You get 7 - 7k
If you have to factorize 7-7k you do the GCD between 7 and 7k (it's 7!) and then divide 7 and -7k by 7
You get 7(1-k)
