The mode is 33 because it is listed 3x's.
Answer:
23) y=3x-7, 3x-y=7
24) y=-6x+9, 6x-y=9
25) y=1/4x+11, x-4y=-44
26) y=-1/2x+4, x+2y=8
Step-by-step explanation:
(10x+21) + (13x) = 90
23x + 21 = 90
-21 -21
23x = 69
/23 /23
x = 3
10(3) + 21
30 + 21 = 51
FEH = 51
13(3) = 39
DEH =39
Answer:
yes, they can be at times
Step-by-step explanation:
6n−20=−2n+4(1−3n)
Simplify both sides of the equation.
−6n−20=−2n+4(1−3n)
−6n+−20=−2n+(4)(1)+(4)(−3n)(Distribute)
−6n+−20=−2n+4+−12n
−6n−20=(−2n+−12n)+(4)(Combine Like Terms)
−6n−20=−14n+4
−6n−20=−14n+4
Add 14n to both sides.
−6n−20+14n=−14n+4+14n
8n−20=4
Add 20 to both sides.
8n−20+20=4+20
8n=24
Divide both sides by 8.
8n/8 = 24/8
n=3
