Andrew= 4 yr.old
Sara=12 yr. old
Tom= 12 yr. old
Basically, what I did was guess and check, but there are other ways also. When I came with Andrew's age of 5 and it was pretty close, I went down to 4 years old and that worked perfect because that way both Tom and Sara are 12 years old.
37 is the answer because it’s greater than and less than
Answer:
One line crosses between -2 and -3
The second line extends past -5 to -3
I wasn't able to give a visual, but you can go to desmos, which is a graphing website and enter the equations there. It'll instantly give you the lines. Good luck
Step-by-step explanation:
28 laps/hour
You divide 35 by 1.25, and you get 28.
Another way is to look at it as 5/4. So 35 divided by 5 gives you 7 laps per 1/4 hour. Then 7 times 4 gives you 28 laps per hour.
Answer:
The answer to your question is ∠QRT = 47; ∠TRS = 133°
Step-by-step explanation:
1.- Find the measure of x
The sum of supplementary angles equals 180°
(3x + 5) + (10x - 7) = 180
3x + 5 + 10x - 7 = 180
13x - 2 = 180
13x = 180 + 2
13x = 182
x = 182 / 13
x = 14
2.- Find the value of ∠QRT
∠QRT = 3x + 5
= 3(14) + 5
= 42 + 5
= 47
3.- Find the value of ∠ TRS = 10x -7
= 10(14) - 7
= 140 - 7
= 133°
