Let's call the first number x, and the second number y. Putting what you have said into equation form:
Subtracting one equation from another gives:
If x = -5,
So the first number is -2, the second number is 9
Answer:
33 1/3 minutes
Step-by-step explanation:
I note x- number of sentences
y=time
when x=3, y=1
x=6, y= 2
I observe that for every 3 sentences I have one more minute ( y increases by 1) so y= x/3
when x=99 i have y=99/3=33 minutes
for x= 100 I have y=100/3minutes= 33 1/3 minutes
Step-by-step explanation:
I think the property I would use is a reflective property
Answer:
94
Step-by-step explanation:
PQS = (7x - 6)°
SQR = (4x + 15)° since QS bisect PQR these two expressions must be equal
so
7x - 6 = 4x + 15 transfer like terms to the same side of the equation
7x - 4x = 15 + 6
3x = 21 divide both sides by 3
x = 7
also the sum of these two would give us the measure of PQR
7x + 4x + 15 - 6 = PQR
11x + 9 = PQR replace x with 7
11*7 + 9 = 86 this is the measure of angle PQR and also supplementary to PQT so the measure of PQT = 180 - 86
Hello :
<span> -7x-6y=59...(1)
-8x-6y=58...(2)
(1)-(2) : x = 1
subsct in (1)
-7-6y = 59
6y =-66
y = -11
