Simplify the expression.
-20a-2b-7
5a-5b3

Step-by-step explanation:

Step 1: Write out the expression separately. Like so:

-20                              5  

Step 2: Since the it's a fraction were dividing. The bases of the exponents are the same, so you can divide the numbers and subtract the exponents.

-20  ÷  5 = -4    

 -   =

-      =

Step 3: Notice that there is a negative exponent. To get rid of the negative, you have to make it positive and move it from being the numerator to being the denominator.

Step 4: Rewrite the expression with the -4, , and .

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
