K + (-4.1) is the exact same as saying k- 4.1, so what you have to do now is put the -4.1 in the opposite side, but with opposite sign too (+)
so k= -9.7 + 4.1
so in order to answer it you have to deduct the number with the lowest value taking in count both as positive and the sign will be the one from the highest value taking both as positive
9.7
-4.1
____
5.6
so 9.7 had a negative sign so the answer to your question is
k = -5.6
i hope i helped you
Answer:
Step-by-step explanation:
k/9=10/3 multiply both sides by 9
k=90/3
k=30
Answer:
76.7
Step-by-step explanation:
11.3(3) + 10.7(4) = __ + 42.8
Multiply values
33.9 + 42.8 = __ + 42.8
The missing value is 33.9!
42.8 + 33.9 = 76.7
See the attached figure to better understand the problem
we know that
in the triangle ABC
tan 61=BC/AC-------> BC=AC*tan 61--------> BC=55*tan 61-----> BC=99.22 ft
tall of the tree =BC+CD-----> 99.22+4.5----> 103.72 ft------> 104 ft
the answer is104 ft
.30 x 65.49 = 19.647
.30 is the 30%
Always place a decimal when trying to find these kinds of answers. 30% of 65.49 is 19.647 or rounded is 19.65
