Answer:
C
Step-by-step explanation:
angle A is 40 so B is 180-40 = 140
vertical angles question
40= 5x
x = 8
Supplementary angle = 180 degrees
angle 1 = x
angle 2 = 3x (three times the supplementary)
3x + x = 180
4x = 180
x = 45 degrees
angle 1 = 45 degrees
angle 2 = 135 degrees
2/3
because 14/3= 2.66666666
14-2.666666= 9.33333333
9.333333/14= 2/3
Answer:
x + y = 36 (1)
7x + 4y = 216 (2)
Step-by-step explanation:
Quanrity of Holiday blend = 36 pounds
Cost per pound of the blend = $6.00
Cost of chocolate chips = $7.00 per pound
Cost of pretzels = $4.00 per pound
Let
Pounds of chocolate chips = x
Pounds of pretzels = y
x + y = 36 (1)
7x + 4y = 36 × $6.00
7x + 4y = 216 (2)
The system of equation is
x + y = 36 (1)
7x + 4y = 216 (2)
Answer:
(p ⋅ 10) − (p ⋅ 2)
Step-by-step explanation:
Try to substitute "p" with any number.
Let's say p = 2
So
p ⋅ (10 − 2)
2 ⋅ (10 − 2)
2 ⋅ (8)
= 16
Now for the other equations
(p ⋅ 10) − (p ⋅ 2)
(2 ⋅ 10) − (2 ⋅ 2)
(20) - (4)
= 16
(10 ⋅ 2) − p
(10 ⋅ 2) − 2
(20 ) − 2
= 18
10 ⋅ 2 − p
10 ⋅ 2 − 2
20 - 2
= 18
(10 ⋅ 2) ⋅ p
(10 ⋅ 2) ⋅ 2
(20) ⋅ 2
= 40
Only (p ⋅ 10) − (p ⋅ 2) has the same result as p ⋅ (10 − 2).
Cheers
