Together, Tim and Tom have $2.40. Tim has three times as much as Tom. How much does each have?

Phoenix [80]

X = how much Tim has
y = how much Tom has
x + y = 2.40
x = 3y
Substitute 3y for x
3y + y = 2.40
4y = 2.40
y = 0.60
Plug in y value into previous equation
x = 3(0.60)
x = 1.80
ANSWERS: Tim has $1.80 and Tom has $0.60

NEED HELP ASAP WORTH LOTS OF POINTS

otez555 [7]

Answer: 2.6

Step-by-step explanation:

PQ = QR (because it’s a rhombus), so

9b - 5 = 3b - 0.8

b = 0.7

And RS = PQ (again because rhombus), so RS = 9b - 5 = 1.3. Since RT is twice RS, we have

RT = 2(1.3) = 2.6.

How are absolute values used to describe quantities ?

Nady [450]

Answer:

Absolute value is a number's distance from 0, so when comparing quantities, such as positive and negative, the greater absolute value is of that number.

For ex:

|-11| > |6| , because |-11| = 11, |6| = 6, and 11 > 6.

So, |-11| > |6|
