Answer:
x ≤ 2
Step-by-step explanation:
2 red rose cost $ 18
x flowers cost $ 11x
"At most " means ≤.
11x + 18 ≤ 40
11x ≤ 40 - 18
11x ≤ 22
x ≤ 2
Answer:
Step-by-step explanation:
<u>Given</u>
<u>Solving in steps</u>
- 1. ⇒ z + (-0.72) - (-0.72) = -2.5 - (-0.72)
- 2. ⇒ z = - (2.5 - 0.72)
- 3. ⇒ z = - 1.78
The student's mistake was adding (-0.72) instead of - (-0.72) or 0.72
Option C:
(11 + 8) + 1 = 11 + (8 + 1)
Solution:
Let us first define the associative property of addition.
<u>Associative property of addition:</u>
(a + b) + c = a + (b + c)
Option A: 5 + 3 = 3 + 5
This represents a commutative property of addition.
i.e. a + b = b + a.
So, it is not true.
Option B: 6 + 1 = 6 + 1
This is not under the property of associative.
It is not true.
Option C: (11 + 8) + 1 = 11 + (8 + 1)
(a + b) + c = a + (b + c)
This reflects the associative property of addition.
It is true.
Option B is the correct answer.
Hence (11 + 8) + 1 = 11 + (8 + 1) illustrates the associative property of addition.
Answer:
no
Step-by-step explanation:
A trapezoid is shown, not a bag. If we assume that this shape is supposed to be the front of the bag, Mariam does NOT have enough pink fabric to make the front of the bag from pink fabric.
The area of the trapezoid shown is ...
A = (1/2)(b1 +b2)h
A = (1/2)(9 in + 8 in)(15 in) = 127.5 in^2
This area is larger than the amount of fabric Mariam has, so she does not have enough.
Answer: ×=5
Step-by-step explanation: Add 3 to both sides. simplify. Subtract 2× from both sides of the equation and u will get ×≡5
