Answer:

Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.

An algebraic expression is one or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs.

Triangle ABC is a scaled copy of triangle DEF. Side AB measures 12 cm and is the longest side of ABC. Side DE measures 8 cm and

olga55 [171]

Answer: scale factor = 1.5

Step-by-step explanation:

$\text{Scale factor}=\dfrac{\text{Side length of image}}{\text{Side length of original figure}}$

Given: Triangle ABC is a scaled copy of triangle DEF.

Side AB = 12 cm and is the longest side of ABC.

Side DE = 8 cm and is the longest side of DEF.

$\text{For similar triangles, Corresponding sides are proportional.}$

AB is corresponds DE (longest side of both triangles)

So, $\text{Scale factor}=\dfrac{\text{AB}}{\text{DE}}=\dfrac{12}{8}=1.5$

Hence, the scale factor = 1.5.

Dominik [7]

$10=2\cdot5\\16=2^4\\8=2^3\\\\\text{lcm}(10,16,8)=2^4\cdot5=80$

80/10=8 packages of plates

80/16=5 packages of napkins

80/8=10 packages of cups
