$-447.82
If she is widthdrawling and paying with money that she doesn’t have, before she puts her paycheck in, then she is in debt of $447.82 which makes it negative.
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.
All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction.An irrational number has endless non-repeating digits to the right of the decimal point. Although irrational numbers are not often used in daily life, they do exist on the number line. In fact, between 0 and 1 on the number line, there are an infinite number of irrational numbers!
I am pretty sure that the triangle is a right isosceles triangle. I am sorry if this answer is not correct, no one is perfect.
Answer:
a) x = 10
b) DA = 24
c) perimeter = 110
Step-by-step explanation:
a) Since it's a parallelogram, the opposite sides are of equal length. This means that line DC = AB, so u can substitute in the values and solve for x:
DC = AB
5x - 18 = 2x + 12 (move terms so that like terms are on the same side)
5x - 2x = 12 + 18 (simplify like terms)
3x = 30 (divide by 3 on both sides to isolate the x)
x = 10
b) now that u know the value of x, you can use it to find the length of DA. again, opposite sides are equal, so DA = BC, which means DA = 3x - 6. substitute in your known value of x and solve:
3x - 6
= 3(10) - 6
= 30 - 6
= 24
Therefore, the length of DA - 24
c) Since u know the length of DA (and therefore BC), u just have to find the length of either DC or AB and then multiply that by 2 and add it.
First, substitute in the value of x for either DC or AB (i'm gonna use AB)
2x + 12
= 2(10) + 12
= 20+12
= 32
now, to find the perimeter use this formula: 2(AB) + 2(DA)
this equals to 2(32) + 2(24) = 64+46 = 110
and that's the perimeter!
hope this helps!
