Since you can directly sum two fractions with the same denominator, we can rearrange the sum as follows:
Now we can sum the first two fraction easily:
We can simplify the first fraction: 12/16=3/4. So, we can sum the two fractions again because they have the same denominator:
Answer:
20 1/3
Step-by-step explanation:
(10*8=80)=(6*[20 1/3-7])
Let being these two angles : angle A and angle B
we know that complementary angles assumed make 90 degree so
m<A +m<B = 90 degrees
and given again angle A is proportional inverse by 0,25 and angle B by 0,1(6)
A = 0,25 *x
B = 0,1(6)*x
A+B=90
0,25x +0,1(6)x =90
x(0,25 +0,1(6)) = 90
x(0,41(6))=90
x = 90/(0,41(6)) = 216,3
measure angle A = 0,25*216,3 = 54,075 degrees
measure angle B = 90 -54 = 36 degrees
Answer:
d 125
Step-by-step explanation:
Supplementary angles add to 180 degrees
Let x be the supplement to the 55 degree angle
55+ x =180
Subtract 55 from each side
55+x-55 =180-55
x = 125
It's easy, just plug the values requested in n & solve:
A(n)=4+(n-1)(8)
second, n=2 ==> A₂ = 4 +(2-1)(8) = 12
fourth, n=4 ===> A₄ = 4 +(4-1)(8) = 20
tenth, n=10 ==> A₁₀ = 4 + (10-1)(8) = 72
This an Arithmetic progression:
with 1st term a₁ =4 & d ( common difference) =8
