PEMDAS

When solving an equation we do them in reverse order

AS  adding and subtracting

MD  multiplication and division

E exponents


Basically we are trying to get the variable alone.

12=10-3x

subtract 10 from each side

then divide by -3 on each side


3/5 x -12 = 18

first add 12 to each side

then multiply by 5/3 to each side

Are the triangles similar? If so, write a similarity statement for the triangles and explain how you know the triangles are simi
andrew-mc [135]

right-handThe triangles are similar if, the ratios of their sides are equal

\frac{AE}{AC}=\frac{AW}{AL}

\frac{8+8}{6+6}=\frac{8}{6}

On the left-hand side

\frac{16}{12}=\frac{4}{3}

and in the right-hand side, we have

\frac{8}{6}=\frac{4}{3}

The left-hand side equals the right-hand side; therefore, the triangles are similar.

4. Sam's parents are teachers who commute 45 miles roundtrip to work 5 2 days a week. His parents spend $38 on gasoline each wee
Marat540 [252]
<h2>Answer:</h2><h2>The correct option is d. (i) and (ii)</h2>

Step-by-step explanation:

The total miles covered per day = 45

No of commuting days in a week = 5

Total miles in a week = 45 * 5 = 225

The total amount spent on gasoline = $ 38

Cost of gasoline per gallon = $ 2.48

The number of gallons consumed per week = \frac{38}{2.48} = 15.32 gallons of gasoline per week.

This confirms (ii) statement

The amount spend on gasoline per mile = \frac{38}{225} = $0.17

This confirms (i) statement

The number of miles per gallon of gasoline = \frac{225}{15.32} = 14.68 miles

The statement (iii) is false.
