Answer:
66
Step-by-step explanation:
42+8x
= 42+8(3)
= 42+24
= 66
Combine like terms in Qx + 12 = 13x + P:
x(Q-13) = P-12
P-12
Then x = ----------
Q-13
Note that Q may not = 13. But none of the answer choices present Q = 13.
Let's go thru the answer choices one by one.
P-12
x = ----------
Q-13
-24
Check out A: Q=12 and P= -12: x = -------- = 24 This is OK (ONE sol'n)
-1
-25
Check out B: Q = -13 and P = -13: x = ----------- = 25/26 OK
-26
13-12
Check out C: Q = -13 and P = 13: x = ------------ = -1/26 OK
-13-13
12-12
Check out D: Q = 12 and P = 12: x= ---------- = 0 OK
12-13
It appears that in all four cases, the equation has ONE solution.
Answer: I got u
Step-by-step explanation:
Set up 2 proportions
562.5 over 12.3 = x over 1
and
353.6 over 8 = x over 1
then cross multiply both of them
12.3x = 562.5
and
8x = 353.6
then divide both of them
round
x = 45.73
and
x = 44.2
based on those answers the petersons were driving faster
Answer:
<em><u>B.</u></em> rectangle, square, quadrilateral, parallelogram, rhombus
Step-by-step explanation:
