Answer:
27.9 dollars
Step-by-step explanation:
2.70= 15 percent
2.70x2=5.4=30 percent
5.4+2.70=8.1=45 percent
8.1x2=16.2=95 percent
95 percent + 15 percent=18.9
18.9=105 percent
in order to subtract 5 percent we need to find 5 percent by dividing 2.70 by 3
which = .9
18.9+9=27.9
100 percent is 27.9 dollars
Answer:
4.73
Step-by-step explanation:
4 8/11=4+8/11
=4/1+811
=(4/1×11/11)+8/11
=44/11+8/11=52/11
We know that
52/11
is the same as
52÷11
Then using
Long Division for 52 divided by 11
and rounding to a Max of 2 Decimal Places gives us
=4.73

Answer:
The first step in solving the equation is "set each binomial factor equal to zero" ⇒ 3
Step-by-step explanation:
To solve a quadratic equation y = ax² + bx + c
- Put y = 0
- Factorize it into two binomial factors (x ± m)(x ± n)
- Equate each binomial factor by 0 to find the values of x
- The values of x are the solution of the equation
∵ The equation is (x + 2)(x - 3) = 0
∵ The equation equated by 0
∵ It is factored into 2 binomial factors (x + 2) and (x - 3)
- The next step is equated each factor by 0 to find the values of x
∴ The 1st step in solving (x + 2)(x - 3) = 0 is set x + 2 = 0 and
x - 3 = 0
The first step in solving the equation is "set each binomial factor equal to zero"
