Answer:
A. 48
B. 24
C. C
Step-by-step explanation:
To divide up whole numbers by fractions, you simply need to just multiply the whole number by the reciprocal of the fraction. in other words, flip the fraction.
Ex.
12 ÷ 1/4
=
12 x 4
Ex. 2
12 ÷ 1/2
=
12 x 2
Answer:
26 1/32
Step-by-step explanation:
<em>Doing good so far</em>
To make an exponent positive, you need to make the number a fraction and move it to the opposite of what it is in <em>(so 4^-3 = 1/4^3)</em>
25 + 1 + (1/(4^3) + 1/(2^6))
26 + (1/64 + 1/64)
26 + 2/64
26 + 1/32
= 26 1/32
30 percent is 30/100 as a fraction so as a decimal it would be 0.30
Answer:
146 or 5,280
Step-by-step explanation:
146: you do 66 + 80
5,280: you do 66 x 80
hope this helps XD
<u><em>subsitution</em></u> means subsituteing something for another and getting the answer
the way to do this is to get an easy equation and make it equal to only one placeholder so
y=2x
so you can subsitute y for 2x anywhere you see a y
3x+y=5
subsitutute
3x+2x=5
5x=5
divide both sides by 5
x=1
subsitute
y=2(1)
y=2
<u><em>elimination</em></u> is when you elimintate one of the terms by adding the equations together and canceling som of them out
so y=2x
subtract y from both sides
0=2x-y or 2x-y=0
add this to the second equation
3x+2x+y-y=0+5
5x=5
divide both sides by 5
x=1
subsitute
y=2(1)
y=2
x=1
y=2
