Answer:
20in
Step-by-step explanation:
the perimeter is 20in because you must add all for sides of the large painting
6+6+4+4=20in
a - 6b + 4c
a - 10b + 4c
-a + 10b + 4c
Answer:
a-6b+4c
Step-by-step explanation:
a-{5b-[a-(3b-2c)+c-(a-2b-c)]}
a-{5b-[a-1(3b-2c)+c-1(a-2b-c)]}
a-{5b-[a+(-3b+2c)+c+(-a+2b+c)]}
a-{5b-[a-3b+2c+c-a+2b+c]}
a-{5b-[-b+4c]}
a-{5b+[b-4c]}
a-{5b+b-4c}
a-{6b-4c}
a+{-6b+4c}
a-6b+4c
(a)
4x + 3y = 23
5x + 2y = 20
(b)
4x + 3y = 23 ⇒ -2(4x + 3y = 23) ⇒ -8x - 6y = -46
5x + 2y = 20 ⇒ 3(5x + 2y = 20) ⇒ 15x + 6y = 60
7x = 14
x = 2
5x + 2y = 20
5(2) + 2y = 20
10 + 2y = 20
2y = 10
y = 5
Answer: biscuit = $2, ice cream = $5
Answer:
3/4=0.75
Step-by-step explanation:
3/4 is equal to .75
(y + 2) = 3(x + 2)
(y − 8) = −3(x − 4)
(y + 8) = −3(x + 4)
