Hi, this is the notation for inclusion of all real
numbers.
We can also state numbers which are positive or negative with a sign on top of the R notation like so:
Answer:
(7/8 - 4/5)^2 = 9/
1600
= 0.005625
Step-by-step explanation:
Subtract: 7/
8
- 4/
5
= 7 · 5/
8 · 5
- 4 · 8/
5 · 8
= 35/
40
- 32/
40
= 35 - 32/
40
= 3/
40
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - seven eighths minus four-fifths = three fortieths.
Exponentiation: the result of step No. 1 ^ 2 = 3/
40
^ 2 = 32/
402
= 9/
1600
In words - three-fortieths squared = nine one-thousand six-hundredths.
Answer:
- 2
Step-by-step explanation:
5x + 3x = - 10 - 6
8x = -16
x = -2
Answer:
<h2>1. t=2m</h2>
Rewrite the equation as 2m=t.
2m=t
Divide each term by 2 and simplify.
m=t/2
<h2>2. y=2x+1</h2>
Isolate the variable by dividing each side by factors that don't contain the variable.
x=y/2−1/2
