Let us say that:
K = age of Kristen
B = age of Ben
From the problem, we make the equations:
eqtn 1: K + B = 32
eqtn 2: (K – 4) = 2 (B – 4)
Simplifying eqtn 2:
K – 4 = 2 B – 8
K = 2 B – 4
Plugging in this to eqtn 2:
(2 B – 4) + B = 32
3 B – 4 = 32
3 B = 36
B = 12
From eqtn 2:
K = 2 B – 4 = 2 (12) – 4 = 20
So Kristen is 20 while Ben is 12.
Answer:
6x²5y²6 cm²
Step-by-step explanation:
(2xy3) x (4x5y6)
(2x) x (4x) = 6x²
(y) x (5y) =5y²
6x²5y²6 cm²
Answer:
The constant in the expression is 12
Step-by-step explanation:
The constant of the expression is the value that is independent of the number of minutes Janelle uses. The expression can be written as :
f(m)=0.05m +12
Example if m is 1 or 2
f(1) = 0.05(1) +12 = 12.05
f(2= = 0.05*2 +12 =0.1 +12 = 12.1
The value 12 is the minimum price of the bill indepent of the consumption of minutes of Janelle. She will always be charged this value.
Answer:
13
Step-by-step explanation:
8--5 = 8 + 5 = 13
Answer:
"simplify"
Step-by-step explanation:
The notion of <em>simplifying</em> an expression depends on the expression. For the one offered as an example, the simplification steps required are eliminating parentheses and combining like terms.
Other possible simplification steps include combining fractions, reducing fractions, and rationalizing denominators (eliminating surds or complex numbers).
It appears the vocabulary word that is desired in the blank is <u>simplify</u>.
