2800 ÷ 400
Cross out 2 zeros from both numbers, then you have 28 ÷ 4 = 7
138° + w° = 180° (sum of angle on a straight line)
w° = 180° - 138°
w = 42
19° + x° + w° = 90°
sub. in w=42,
19° + x° + 42° = 90°
x° = 90° - 19° - 42°
x° = 29°
x = 29
I don't know for sure I'm going to ace grade next year but I know that you you need to put the coefficients with the same variable together and the variable next to the coefficients and multiply or add or divide or subtract them and you get your answer and this is just 7th grade math I'm relying on
Yes bc 6 groups and a bout 4 are in it ...........
A linear relationship is an equation that has a constant slope
The equation that does not represent a linear relationship is (b) y = 2x^2 + 5x
<h3>How to determine the non-linear relationship</h3>
A linear equation can take any of the following forms:
y = mx + b
y - y1 = m(x - x1)
Ax + By = c
Any form different from the above forms is not a linear equation
Using the above format as a guide, the equation that does not represent a linear relationship is (b) y = 2x^2 + 5x
