Answer:
B. subtraction property of inequality
Step-by-step explanation:
Adding both equations cancels y:
<span>4x + 8y = 16
</span><span>4x - 8y = 0
-----------------+
8x = 16 => x=2
filling in x=2 in the first equation gives:
4*2 + 8y = 16 => 8y = 8 => y=1
So (2,1) is the (x,y) pair that solves the two equations. Answer C.</span>
1.7a + 0.3a = 0.8;
(1.7 + 0.3)a = 0.8;
2 x a = 0.8;
a = 0.8 ÷2;
a = 0.4;
Answer:
$2327.5
Step-by-step explanation:
The stock of company A lost 2% today .
Let the price of the stock at the beginning of the day be A.
Therefore, a 2% loss of A = $46.55
That’s
2% /100% x A = $46.55
0.02 x A = $46.55
Divide both sides by 0.02
0.02/0.02 x A = $46.55/0.02
A = $2327.5
The price of stock at the beginning of the opening day was $2327.5
Answer:
The value of x = 4
Step-by-step explanation:
In this question, we are asked to calculate the value of the angle x
Here the ray cuts the angle into half.
Since the total of the angle was 120, half of this would be 120/2 = 60
Now, it is this value of 60, that our new angle equals to
Mathematically;
3x + 48 = 60
3x = 60-48
3x = 12
x = 12/3
x = 4
