Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.

Fifteen more than half a number is 9
rusak2 [61]

For this case, the first thing we must do is define a variable.

We have then:

x: unknown number

We now write the equation that models the problem:

(\frac{1}{2}) x + 15 = 9

From here, we clear the value of x.

We multiply both sides of the equation by 2:

(\frac{2}{2}) x + 2 (15) = 2 (9)\\x + 30 = 18

We subtract 30 on both sides of the equation:

x + 30 - 30 = 18 - 30\\x = -12

Answer:

The value of the unknown number is given by:

x = -12

Find the values of x and y
Mkey [24]

Answer:

x = 78º

y = 35º

Step-by-step explanation:

These are isosceles triangles

two angles are congruent

-----------------------------

x + 51 + 51 = 180

x = 180 - 102

x = 78º

y + y + 110 = 180

2y = 70

y = 35º

in Ryan's V. Class 50% of the students like the teacher if 15 of the students like the teacher how many students are in that cla
Anton [14]

Answer: 30 students.

Step-by-step explanation: They are saying 50% of the class like the teacher. We know that 50% is half of the 100% so that mean only half of the students like the teacher. Is 15 students like the teacher it means that 15 are half of the students in the class. The other half should be another 15. So 15+15=30 or 15x2=30.

I hope I didn’t make it to confusing.
