Answer:

segments: using the same number of hash marks
angles: using the same number of arcs, or hash marks on an arc

Step-by-step explanation:

The attached diagram shows that segments AC and BD are congruent by using a single hash mark on each of those segments. If other segments are congruent, but not congruent to these two, the "decoration" would be different, probably two hash marks. Segments marked with the same "decoration" are intended to be understood as congruent.

The "decoration" used for congruent angles is an arc of some kind. Here, a single arc is used to signify angle CAB is congruent to angle DBA. Additional arcs could be used for other congruent angles, or hash marks can be put on the arcs.

t a gas station, 15 gallons of gas has a price of $17.55 and 18 gallons of gas has a price of $21.06. Write a direct variation e

yaroslaw [1]

Use constant of variation y =kx i.e
15 gallons k=>17.55
k gallons =17.55/15=1.17

18 gallons k=>21.06
k gallons =21.06/18=1.17

Therefore ans => y=1.17x

What is the coefficient of the term 67xy 1/7, 6, 6xy, and 6/7 Which one do I pick?

Scorpion4ik [409]

You would pick You would choose 6xy, or 67xy, unless that is with the 1/7,
and this is because the definition of a coefficient is "<span>a numerical or constant quantity placed before and multiplying the variable in an algebraic expression",
so both of these have variables.</span>

M–[(m–n)÷(−2)](−5), if m=−4, n=−6

jeka94

Answer:

-9

Step-by-step explanation:

We are given the expression m–[(m–n)÷(−2)](−5). Substituting -4 for m and -6 for n, we get:

-4–[(-4 + 6)÷(−2)](−5)

We must do the work that appears inside parentheses first:

-4–[( 2 )÷(−2)](−5)

Next we must do the work that appears inside square brackets:

-4–[ -1 ](−5)

Multiplication comes next. The above expression becomes:

-4 - [ 5 ]

which in turn comes out to -9
