Answer:
-8n + 9
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
A = -3n + 2
B = 5n - 7
A - B
<u>Step 2: Simplify</u>
- Substitute: -3n + 2 - (5n - 7)
- Distribute negative: -3n + 2 - 5n + 7
- Combine like terms (n): -8n + 2 + 7
- Combine like terms (Z): -8n + 9
Answer:
48 ft^2
Step-by-step explanation:
5.5 times 6 equals 33 (larger square part)
2.5 times 6 equals 15 (two triangles combined so you dont have to 1/2)
Work the information to set inequalities that represent each condition or restriction.
2) Name the
variables.
c: number of color copies
b: number of black-and-white copies
3)
Model each restriction:
i) <span>It
takes 3 minutes to print a color copy and 1 minute to print a
black-and-white copy.
</span><span>
</span><span>
3c + b</span><span>
</span><span>
</span><span>ii) He needs to print
at least 6 copies ⇒
c + b ≥ 6</span><span>
</span><span>
</span><span>iv) And must have
the copies completed in
no more than 12 minutes ⇒</span>
3c + b ≤ 12<span />
4) Additional restrictions are
c ≥ 0, and
b ≥ 0 (i.e.
only positive values for the number of each kind of copies are acceptable)
5) This is how you
graph that:
i) 3c + b ≤ 12: draw the line 3c + b = 12 and shade the region up and to the right of the line.
ii) c + b ≥ 6: draw the line c + b = 6 and shade the region down and to the left of the line.
iii) since c ≥ 0 and b ≥ 0, the region is in the
first quadrant.
iv) The final region is the
intersection of the above mentioned shaded regions.v) You can see such graph in the attached figure.
Answer:
11
Step-by-step explanation:
11 BOXES OF ORANGES IS $33
7 BOXES OF PEARS IS $35
WHICH EQUALS $68
MEANING THERE IS 11 BOXES OF ORANGES
