Peggy is thinking of a number such that when twice the number is added to three times one more than the number she gets the same result as when she multiplies four times one less than the number. what number is peggy thinking of?

-7

Step-by-step explanation:

Lets assume the number Peggy is thinking of be "x".

Now as given, when twice the number is added to three times one more than the number. We can write it as

∴ --- Equation 1

Again, it is given that Peggy gets the same result as when she multiplies four times one less than the number.

∴ -- equation 2

Next, we can equate both the equation 1 and 2 as it is given that result is same.

Let´s distribute 3 into and 4 into

⇒

⇒

Subtract both side by 4x and 3

∴

∴ Peggy was thinking of -7

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
