t < -3
Answer:
x = 200 packages.
B
Step-by-step explanation:
1 strip of tape = 2.375 inches
Each package requires 4 such strips or 4 * 2.375 which is 9.5 inches.
Set up a proportion for the rest of the problem
1 package / 9.5 inches tape = x packages / 1900 inches tape.
Multiply both sides by 1900
1*1900 / 9.5 = x
1900/9.5 = x
x = 200 packages.
Answer:
The answer to your question is below
Step-by-step explanation:
A) 2x > -6
x > -6/2
x > -3
It must be a graph with an open circle starting at -3 and then to the right.
It is the first graph.
B) x - 4 < -7
x < -7 + 4
x < -3
The graph must be an open circle starting at -3 and pointing to the left.
it is the second graph.
C) 6 + x ≤ 3
x ≤ -6 + 3
x ≤ -3
The graph must be a closed circle starting at -3 and pointing to the left.
it is the forth graph.
D) -x - 5 ≤ -2
-x ≤ -2 + 5
- x ≤ 3
x ≥ -3
The graph must be a closed circle starting at -3 and pointing to the right.
It is the third graph.
A square has the same width and height, so find the gcd of 90 and 126. Here are there factors:
90:1,2,3,5,9,10,15,18,30,45,90
126:2,3,6, 7,9,14,18,21,42,63,126
18 is the largest in both so the number of squares will be
90/18 * 126/18
= 5*7 = 35
The answer is 10
