Answer:
There are no solutions
Step-by-step explanation:
-3u=-3u-10
Add 3u to each side
-3u+3u=-3u+3u-10
0 = -10
This is never true so there are no solutions
Answer:
1/4
Step-by-step explanation:
Males: 3 units
Females: 1 unit
Total: 4 units
Females/Total: 1/4
Answer:
Step-by-step explanation:
Ratio of length : width = 4 : 7
Length = 4x
Width = 7x
Longer side = 31.5 in
⇒ 7x = 31.5
Divide both sides by 7
x = 31.5/7
x = 4.5
length = 4x
= 4*4.5
l = 18 in
width = 31.5
w = 31.5 in
= 2*18 + 2*31.5
= 36 + 63
= 99 in
= 18*31.5
= 567 in²
This would be no solution , there is none
Answer:
CD ≠ EF
Step-by-step explanation:
Using the distance formula
d =
with (x₁, y₁ ) = C(- 2, 5) and (x₂, y₂ ) = D(- 1, 1)
CD =
=
= =
Repeat using (x₁, y₁ ) = E(- 4, - 3) and (x₂, y₂ ) = F(- 1, - 1)
EF =
=
= =
Since ≈ , then CD and EF are not congruent
