Malik collects rare stamps and has a total of 212 stamps. He has 34 more domestic stamps than foreign stamps. Let x represent th e number of domestic stamps and let y represent the number of foreign stamps. This system of equations models the given information for both stamp types.
x – y = 34
x + y = 212
1 answer:
Answer:
y = 89 x = 123
Step-by-step explanation:
since they're both in standard form, its easier to do the process of elimination
x - y = 34
-x -y -212
------------------
-2y = -178
y = 89
now plug in y to any one of those two equations
x - y = 34
x - 89 = 34
x = 123
<em>to check:</em>
<em>x</em><em> </em><em>+</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>2</em><em>1</em><em>2</em>
<em>1</em><em>2</em><em>3</em> <em> </em> <em>+</em><em> </em><em>8</em> <em>9</em> <em> </em><em>=</em><em> </em><em>2</em><em>1</em><em>2</em>
<em>2</em> <em>1</em> <em>2</em> <em> </em> <em>=</em><em> </em><em>2</em><em>1</em><em>2</em>

Answer:
(11, ∞).
Step-by-step explanation:
3 (x+2)+9<6(x-3)
3x + 6 + 9 < 6x - 18
-3x < -18 - 6 - 9
-3x < -33
x > 11 (Note the inequality flips as we are dividing by a negative value).

Answer: D) cube root of 16
================================================
Explanation:
The rule we use is
In this case, x = 4, m = 2 and n = 3.
So,
Showing that the original expression turns into the cube root of 16.

Step-by-step explanation:
3/x=5/7 is the same as A 21=5x Both equal to 21/5 or 4 1/5
Answer:
-4
Step-by-step explanation:
-4t+15=-1
Subtract 15 on both sides:
-4t=-16
Divide -4 on both sides:
t=-4
