Next time, please share your system of linear equations by typing only one equation per line:
<span>3x - 2y - 7 = 0 5x + y - 3 = 0 NO
</span><span>3x - 2y - 7 = 0
5x + y - 3 = 0 YES
Mult. the 2nd equation by 2 so as to obtain 2y, which will be cancelled out by - 2y in the first equation:
</span><span> 3x - 2y - 7 = 0
2(5x + y - 3 = 0)
Then:
3x - 2y - 7 = 0
10x +2y - 6 = 0
----------------------
13x - 13 = 0, so that x = 1. Find y by subbing 1 for x in either of the 2 given equations.</span>
Answer:
a₃₅ = 182
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 17 - 12 = 22 - 17 = 5
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 5 , then
a₃₅ = 12 + (34 × 5) = 12 + 170 = 182
(-7,-8) is the center and 8 is the radius.
Answer: 50 square yards
Step-by-step explanation:
From the question, we are informed that Kevin wants to cover a rectangular floor that is 15 feet by 30 feet with carpeting.
The first thing to do is to convert the measurement that were given to yards. We should note that 1 yard = 3 feet
15 feet = 15/3 = 5 yards
30 feet = 30/3 = 10 yards
Area = 5 × 10 = 50 square yards
Answer:
b = 9
Step-by-step explanation:
Step 1: Add <em>b</em> on both sides (Addition Equality)
5/3b + 5 = 20
Step 2: Subtract 5 on both sides (Subtraction Equality)
5/3b = 15
Step 3: Divide both sides by 5/3 (Division Equality)
b = 9
