0 is the answer 79.83-54.91-24.92=0
Carla = 5 years old
Jim = 2 years old
Peter = 15 years old
(Peter was 14 years old one year ago)
5+2=7
7x2=14 (14 is the age from one year ago meaning 15 is the current age)
15-2=13
Answer:
-9/4 ÷ (-2/3)
Step-by-step explanation:
-(2 1/4) ➡ -9/4
-2/3 ➡ (again a reciprocal needed) -3/2 since we need the result to be positive both expression should remain negative so the answer is -9/4 ÷ -2/3
Answer:
upon graphing, it is linear
Step-by-step explanation:
you could set up an x-y table or you could graph it
if you graph it you'll see it's linear with a y-intercept of -2 and a slope of 9
all linear equations are functions except for vertical lines
Answer: See explanation
Step-by-step explanation:
Total number of text messages = 800
Amount used by Tommy and Mary = 1/2 × 800 = 400
Number of messages uses by Jack and Stefanie = 240
The expression to find the number of messages Cathy uses will be:
= 800 - (1/2 × 800) - 240
Since the expression is 800 - (1/2 × 800) - 240, the number of messages that Cathy will use will be:
= 800 - (1/2 × 800) - 240
= 800 - 400 - 240
= 160 messages
