M+7+(-15m) + 9-17m= 58

Mathematics
1 answer:
ELEN [110]3 years ago
7 0

Answer:

m=-\frac{42}{31}

Step-by-step explanation:

m+7+\left(-15m\right)+9-17m=58

Remove brackets:

m+7-15m+9-17m=58

Group the similar terms together:

m-15m-17m+7+9=58

-31m+16=58

Subtract 16 from both sides:

-31m+16-16=58-16

-31m=42

Divide both sides by -31:

\frac{-31m}{-31}=\frac{42}{-31}

m=-\frac{42}{31}

In ΔIJK, k = 3.6 inches, i = 1.3 inches and ∠J=13°. Find the length of j, to the nearest 10th of an inch.
KonstantinChe [14]

Answer:

5.6 inches

Step-by-step explanation:

let c = length of 'j'

I used the Law of Cosines:  c^{2} = a^{2} + b^{2} -2ab· cosC

= (1.3)^2 + (3.6)^2 - 2(1.3)(3.6) x 0.97

Determine whether or not the triangle with the given side lengths is a right triangle.

I believe it is not a tight trying because as I was taught, A+B=C & C-A=B which does not work out in this case.

The scientific notation should mimic the number. For example, the scientific notation of 104,000,000,000 would be 1.04 x 10^11, not 1.4 or 1.004. Your answer should be 4.092 × 10^11.
