Answer:

x=11.5

Step-by-step explanation:

You want to isolate x. The first thing you have to do is get rid of that tricky fraction. To do this, you have to multiply the fraction by its denominator to cancel the denominator out and leaving you only with the numerator. You would also have to multiply 3 by 5.5 too. (Multiplying by the denominator only gets rid of the denominator and leaves the numerator alone. However, in your case, the numerator is one, so by getting rid of the denominator you get 1x. This can just be written as x.)

Equation would look like this:

x+5=16.5

You subtract 5 from both sides, and 16.5 minus 5 is 11.5

Equation would now look like this:

x=11.5

Answer:

$\Huge\boxed{x=33.2}$

Step-by-step explanation:

Hello there!

We can solve for x using law of sines

As we can see in the image a side length divided by sin ( its opposite angle) = a different side length divided by sin ( its opposite angle)

So we can use this equation to solve for x

$\frac{21}{sin(35)} =\frac{x}{sin(65)}$

Our objective is to isolate the variable using inverse operations so to get rid of sin (65) we multiply each side by sin (65)

$\frac{x}{sin(65)} sin(65)=x\\\\\frac{21}{sin(35)} sin(65)=\frac{21sin(65)}{sin(35)}$

we're left with

$x=\frac{21sin(65)}{sin(35)}\\x=33.18208755$

assuming we have to round the answer would be 33.18 or 33.2

Antoine Purchase 1.8 kg of apples and 315 dekagrams of oranges This was 1350 g more than the weight of bananas bridges what was

victus00 [196]

Answer: 3600 grams

Step-by-step explanation:

A dekagram means 10 grams.

1 kilogram = 1000 grams

Therefore the total number of grams when Antoine Purchase 1.8 kg of apples and 315 dekagrams of oranges will be:

= (1.8 × 1000) + (315 × 10)

= 1800 + 3150

= 4950 grams

Since this was 1350g more than the weight of bananas, the weight of the bananas Antonio purchased in grams will be:

= 4950 - 1350

= 3600 grams
