Answer:
34.4
Step-by-step explanation:
10% is the same thing as 0.1 so 344 times 0.1 is 34.4
A percent (%) is equal to 1/100 (We actually don't call that 'per''cent' for no reason)
So 10% is actually 10 times % which is:
If you get a calculator and calculate 1/10 the calculator should give 0.1
You might be taught that to get the decimal form from percent you just move the decimal point to the left twice (like 34% -----> .34) but if you do this, you are essentially dividing by 100 or multiplying by 1/100
now you know 10% is 0.1 the next thing to do is multiply it to 344.
Using substitution:
13(y+6)-6y=22
13y+78-6y=22
7y+78=22
/// -78 -78
7y=-56
÷7 ÷7
y=-8
x=y+6
x=-8+6
x=-2
So, x equals -2 and y equals -8.
Answer:
Option b: -5xy(x - 2 + 3y)
The x intercept of the given line is (10, 0)
<h3>Finding the x intercept of a line</h3>
The x intercept of a line is the point where the line crosses the x-axis
It is the point where the value of y is zero
Given the equation of a line -2x+5y = -20
Substitute y = 0 into the equation
-2x +5(0) = -20
-2x = -20
x = 10
Hence the x intercept of the given line is (10, 0)
