You want to use PEMDAS for this.
<em>P</em>= arenthesis ( )
<em>E</em>= xponents a²
<em>M</em>= ultiply ×
<em>D</em>= ivide ÷
<em>A</em>= dd +
<em>S</em>= ubtract -

What you want to do is go in order and ask yourself as you go.
Are there any <u><em>Parenthesis</em></u>? <em>No
</em>Are there any <u><em>Exponents</em></u><em />? <em>No</em>
Is there any <em /><u><em>Multiplication</em></u><em />? <em>Yes
</em>
<em />Is there any <em><u>Division</u></em>? <em>No
</em>
<em />Is there any <em><u>Addition</u></em>? <em>No
</em>
<em />Is there any <em><u>Subtraction</u></em><u />? <em>Yes</em><em>
</em>
<em />Thats when you stop and you multiply what you have in the PEMDAS. Top to bottom. 3x5 which gives you 15. Now you equation is 45-15. Thats when you subtract and you get your answer which is 30.

Answer:

y = 7

Step-by-step explanation:

The similarity statement ABCD \sim WXYZ tells you which vertex from the first polygon corresponds to which vertex from the second polygon.

A is paired with W, B is paired with X, C is paired with Y, D is paired with Z.

The expression <em>y</em> + 2 is placed along side WZ which corresponds to side AD in the first polygon.

Now locate two sides, one from each polygon, that are labeled with just <u>numbers</u>.  That way, you'll be able to tell what the proportion is between the two shapes.

AB and WX correspond and are labeled 5 and 3, respectively.

Now you can write a proportion:

\frac{WX}{AB}=\frac{WZ}{AD}\\\\\frac{3}{5}=\frac{y+2}{15}

Use the Means-Extremes Property ("cross multiply").

5(y+2)=3(15)\\\\5y+10=45\\\\5y=35\\\\y=7

What is the estimated temperature if the dissolved salt is 98g?<br><br> 54<br> 61<br> 161<br> 171
madreJ [45]

Ths solubility curve is used to show the amount of salt dissolved (solubility).

<h3>What is the solubility curve?</h3>

The solubility curve is a depiction of the solubility of a substance plotted against its temperature. It can be used most times to show the solubility of a susbtance at different temperatures. This question is incomplete hence so we can not be able to obtain the solubility of the salt at this temperature.

If the solubility curve has been shown in the graph, then we can be able to obtain the solubility of the salt from the data shown on the plot.

Which is the correct classification for the triangle?
kondaur [170]
Acute means that has 3 angles less than 90 degrees

obtuse means at lesat 1 angle is more than 90 degrees

right triangle means 1 angle=90 degrees

s we solve for thierd angle
all angles add to 180 so
35+45+x=180
80+x=180
subtract 80
x=100
100>90

obtuse angle is answer
