Let us solve this system of equations by using the elimination method. Adding the 2 equations, we get

9x + 5y - 9x + 4y = -33 + 6

9y = -27

y = -3

Substituting this value of y in the first equation, we get

-9x + 4(-3) = 6

-9x - 12 = 6

9x + 12 = -6

9x = -18

x = -2

Therefore, x = -2, and y = -3. Hope this helps! If you have any questions, feel free to ask.

Maritza remembers her PIN because it is between 1,000 and 1,500 and it is the product of two consecutive prime numbers. What is

valentina_108 [34]

Answer:

The PIN is 1147

Step-by-step explanation:

Prime numbers

These are integer numbers that only divide exactly by themselves and by 1. To find the first possible prime number between 1,000 and 1,500, calculate the square root of 1,000.

$\sqrt{1000}\approx 31.6$

Thus, the first prime to consider is 31. Write the consecutive primes from 31:

31 , 37 , 41 , 43

We can see the only two consecutive primes whose product lies in the given interval are 31 and 37. Thus, the PIN is 31*37=1147

$\bold{\huge{\red{\underline{Solution}}}}$

$\bold{\underline{ Given :- }}$

We have given two figures that rectangle and parallelogram
The base and height of parallelogram is 7ft and 5ft
The length and breath of rectangle is 3ft and 1ft .

$\bold{\underline{ To \: Find :- }}$

We have to find the area of shaded part?

$\bold{\underline{ Let's \: Begin :- }}$

Firstly, we will calculate the area of parallelogram then area of rectangle after that we will subtract the area of rectangle from the area of parallelogram then we got the area of shaded part.

$\sf{\pink{Area \:of\: parallelogram = Base * height }}$
