Answer:
C) 
E) 
F) 
Step-by-step explanation:
C)
One is given the following equation
In order to simplify fractions, one must convert the fractions to a common denominator. The common denominator is the least common multiple between the given denominators. Please note that the denominator is the number under the fraction bar of a fraction. In this case, the least common multiple of the denominators is (
). Multiply the numerator and denominator of each fraction by the respective value in order to convert the fraction's denominator to the least common multiple,
Simplify,
E)
In this case, one is given the problem that is as follows:
Use a similar strategy to solve this problem as used in part (c). Please note that in this case, the least common multiple of the two denominators is the product of the two denominators. In other words, the following value: (
)
Simplify,
F)
The final problem one is given is the following:
For this problem, one can use the same strategy to solve it as used in parts (c) and (e). The least common multiple of the two denominators is (
). Multiply the first fraction by a certain value to attain this denomaintor,
Simplify,
$45.50 ÷ 26% = $175
Total sales for the day is $175.
Answer:
Replace the “x" with actual numbers these as the answers after working on each; = 7/5
= 2
= - 2
= 1/2
= 5/3
Answer. First option: -1
Solution:
We have a triangle, and we know two angles of 60° each one. We can find the third angle A, using:
A+B+C=180°, with B=60° and C=60°:
A+60°+60°=180°
Solving for A: Adding similar terms:
A+120°=180°
Subtracting 120° both sides of the equation:
A+120°-120°=180°-120°
A=60°
The third angle A is 60° too, then the triangle has three equal angles of 60° each one, and it is an equillateral triangle, thus its three sides must be congruents:
2y+6=4=2x-3
We need to find the value of y, then using the first equality:
2y+6=4
Solving for y: Subtracting 6 both sides of the equation:
2y+6-6=4-6
2y=-2
Diniding both sides of the equation by 2:
2y/2=-2/2
y=-1
