Add the opposite of the number 1 3/4 to the sum of the numbers 5 2/3 and (−2 5/6 )

Mathematics
1 answer:
MAVERICK [17]3 years ago
8 0

Answer:

Step-by-step explanation:

5 2/3 + (-2 5/6)

=\frac{17}{3}-\frac{17}{6}\\\\=\frac{17*2}{3*2}-\frac{17}{6}\\\\=\frac{34}{6}-\frac{17}{6}\\\\=\frac{34-17}{6}\\\\=\frac{17}{6}\\\\=2\frac{5}{6}

2 5/6 + (- 1 3/4) = 2 5/6 - 1 3/4

\frac{17}{6}-\frac{7}{4}\\\\=\frac{17*2}{6*2}-\frac{7*3}{4*3}\\\\=\frac{34}{12}-\frac{21}{12}\\\\=\frac{34-21}{12}\\\\=\frac{13}{12}\\\\=1\frac{1}{12}

5x + 6y = 20 , 8x - 6y = -46
serg [7]

Answer:

5x + 6y = 20_____(1)

8x - 6y = -46_____(2)

Solving simultaneously:

Eqn(1) + Eqn(2)

5x + 8x + 6y + (-6y) = 20 + (-46)

13x = -26

x = -2

substituting this into Eqn (1):

5(-2) + 6y = 20

-10 + 6y = 20

6y = 30

y = 5

hence:

x = -2,y = 5.

What is the product of (x − 3) and (x + 7)?
NeX [460]

Answer:

The product of (x-3) and (x+7) is x² + 4x - 21

Step-by-step explanation:

The product of (x-3) and (x+7) is x² + 4x - 21

The product of (x - 3) and (x + 7) can be found as follows:

(x - 3)(x + 7)

open the bracket by multiplying

Therefore,

x(x) +x(7) - 3(x) - 3(7)

x² + 7x - 3x - 21

combine like terms

x² + 4x - 21

HELP, Prove: (cos(x))/(sin(x)tan(x))=cot^2x
Mice21 [21]

Answer:

Steps shown below

Step-by-step explanation:

We will simplify this using definitions and identities. Let's start.

\frac{cos(x)}{sin(x)tan(x)}

Using tanx=\frac{sinx}{cosx}, we have:

\frac{cos(x)}{sin(x)\frac{sin(x)}{cos(x)}}\\=\frac{cos^2(x)}{sin^2(x)}

Using cot(x)=\frac{cos(x)}{sin(x)}, we have:

\frac{cos^2(x)}{sin^2(x)}\\=cot^2(x)

Hence, proved.
