\large\mathfrak{{\pmb{\underline{\blue{To\:find}}{\blue{:}}}}}

The value of x.

\large\mathfrak{{\pmb{\underline{\orange{Solution}}{\orange{:}}}}}

\longrightarrow{\green{x=12° }} 

\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}

We know that,

\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}

➪ 95° + (3x +4)° + (4x - 3)° = 180°

➪ 3x + 4x + 95° + 4° -3° = 180°

➪ 7x + 96° = 180°

➪ 7x = 180° - 96°

➪ 7x = 84°

➪ x = \frac{84°}{7}

➪ x = 12°

Therefore, the value of x is 12°.

Now, the three angles of the triangle are 95°, 40° and 45° respectively.

\large\mathfrak{{\pmb{\underline{\purple{To\:verify}}{\purple{:}}}}}

✒ 95° + 40° + 45° = 180°

✒ 180° = 180°

✒ L. H. S. = R. H. S.

\boxed{Hence\:verified.}

Allie bought a 5-pound bag of trail mix. She gave 12 ounces of trail mix to Justin. Then she put the rest of the trail mix into
trapecia [35]
To solve this problem, you will first want to convert 5 pounds into ounces. To do this, first determine how many ounces is in 1 pound.

There are 16 ounces in 1 pound, so to convert 5 pounds into ounces, you simply have to multiply 5 × 16. This will give you 80 ounces total.

Allie give 12 ounces away, so you must first subtract 12 ounces from your total (80 ounces). 80 - 12 gives us 68 ounces.

Allie then divides the trail mix up into 4 ounce portions. To figure out how many small bags she can make, you simply divide your new total (68 ounces) by 4. 

68 ÷ 4 = 17

Allie made 17 small bags.
