Answer:
B and C
Step-by-step explanation:
(15)
The opposite sides of a parallelogram are equal , so
CD = AB , that is
7x - 54 = 5x - 2 ( subtract 5x from both sides )
2x - 54 = - 2 ( add 54 to both sides )
2x = 52 ( divide both sides by 2 )
x = 26
Then
CD = 7x - 54 = 7(26) - 54 = 182 - 54 = 128 → B
(16)
Consecutive angles are supplementary, sum to 180° , then
6y + 19 + 2y + 9 = 180
8y + 28 = 180 ( subtract 28 from both sides )
8y = 152 ( divide both sides by 8 )
y = 19
Then
∠ B = 6y + 19 = 6(19) + 19 = 114 + 19 = 133°
Opposite angles are congruent , so
∠ D = ∠ B = 133° → C
Answer:
greater than
Step-by-step explanation:
half the times the cube was rolled it landed on six the theoretical probability is only eight, 48 > 8
Answer:
x=8
Step-by-step explanation:
5(x+2)=6x+3x-14
5x+10=6x+3x-14. distributive property
10+14=8x-5x. combine like term
24=3x. addition and subtraction property
24/3 = 3x/3. division property
8=x
> x = 8
Answer:
y=2.50x+20
Step-by-step explanation
Slope intercept equation is = y=mx+b
So you BEGIN with 20, which is your membership fee (it only gets charged once) then your mx is your slope. 2.50 is your slope because they earn 2.50 for each (x) video rented.
you place a number beside the x for each video rented. For example, if you rent 2 videos then you write this y=2.50(2)+20
