Example Question #42 : Ssat Middle Level Quantitative (Math)

If , then what is the value of 

Possible Answers:

Correct answer:

Explanation:

To solve for the equation, , we add 7 to each side. By doing this, we can see that y is equal to 19. 

 

Thus, in the equation , we plug in 19 for y. 

Thus, 15 is he correct answer. 

Example Question #42 : Ssat Middle Level Quantitative (Math)

Marcia is four times as old as her daughter Janice. In twelve years, Janice will be 20 years old. In how many years will Marcia be three times as old as Janice? 

Possible Answers:

Correct answer:

Explanation:

Janice will be 20 years old in 12 years, so she is  years old now. Marcia is four times as old, or  years old.

Let  be the number of years in which Marcia's age will be three times Janice's age. Janice will be  years old, and Marcia will be  years old. Since Marcia will be three times as old as Janice, we can set up and solve the equation:

Example Question #47 : Equations

You must first use the distributive property to solve this problem. 

Find the value of the variable

Possible Answers:

Correct answer:

Explanation:

First distribute the 3 over to the terms inside the parantheses. You should get the following value

Second subtract 12 on both sides of the equation,

Then isolate the variable "a" by dividing both sides by 3,

You can check your answer by inserting 4 into the original equation and solve the equation. 

Example Question #48 : Equations

A mother takes her three children to the doctor for their yearly checkup. During the checkup, the nurse asks to see the children in order of increasing age. Based on the following information, which child will the nurse see first?

  • Zach and Paul have combined ages of 15.
  • Paul and Anna have combined ages of 16.
  • Anna and Zach have combined ages of 17. 
Possible Answers:

None of these answers

Zach

Anna

All three children are the same age.

Paul

Correct answer:

Paul

Explanation:

Based on the information provided in the question, the nurse will see the youngest child first. To determine which child is youngest, the ages of all children must be found. The three lines of information can be converted to equations using Z = Zach, P = Paul, and A = Anna.

Isolate Z in the first equation by subtracting P from both sides of the equal sign. Use the newly found relationship in equation 3 and simplify as necessary.

A or P can be isolated, similar to above, as both variables appear in equation 2. Plug the isolated equation in equation 2 and again simplify as necessary. For this explanation A has been solved for.

This means that Paul is 7 years old. Plug this information into the original equation.

So, Paul is 7 years old, Zach is 8 years old, and Anna is 9 years old; therefore, Paul will be seen by the nurse first.
