divide all both sides by the number with the x
for example 18 = 2x would be 9
18 divided by 2 is 9
2 divided by 2 would be canceled out.
so x would be 9
If it is 0.9 meters long and then he cuts the pipe into 4 equal pieces, then you would just do the equaton: 0.9÷4 and the answer would be 0.225
Answer:
A, D, and E
Step-by-step explanation:
80% off 22 is 17.6
A- 80 ? 100=0.8 x 22= 17.6
D- 0.8 x 22= 17.6
E- 4/5=0.8 x 22= 17.6
The expected value of y when x-value is 45 is 35.06
Any equation which can be put in the form ax + by + c = 0, where a, b and c are real numbers, and a and b are not both zero, is called a linear equation in two variables. For example, y = 2x+3 and 2y = 4x + 9 are two-variable linear equations.
In the given question value of x is given and value of y is asked.
The given equation : y = -2.61x+152.51 Such questions can be solved by substituting the given value of variable in the equation which will help us find the unknown.
Substituting x = 45 in the given equation , we get
y = -2.61 x 45 + 152.51
y = -117.45 + 152.51
y = 35.06
Thus the expected value of y when x-value is 45 is 35.06
