### SAT 2022 Math Practice Test 37 Grid Ins Questions with Answer Keys

SAT Math Practice Online Test Question No 1:

Given f(x) = √(164 + 5x) and g(x) = x – 8, find the value of x for which f(x) = g(x).

When f(x) = g(x), √(164 + 5x) = x – 8.

To solve this equation, you need to square both sides, which gives you 164 + 5x =  – 16x + 64. (Notice that I’m using the same cool formula from Question 8 of Section 3.) To solve the equation, you need it to equal zero, which you get by subtracting 164 and 5x from both sides.

That gives you  – 21x – 100 = 0, which factors to (x – 25)(x + 4) = 0, which makes x either 25 or –4; go for 25 because you can’t grid a negative answer.

SAT Math Practice Online Test Question No 2:

Find a value of x that satisfies x2 = 3x + 10.

You first want to put everything on one side of the equation, so that you can factor:  – 3x – 10 = 0.

To the factor, you’re looking for two numbers that multiply to –10 that also have a difference of 3. The numbers –5 and 2 will do the trick: (x – 5)(x + 2) = 0.

Now set each factor equal to 0 and solve for x. You find that x is 5 or –2. Because it’s impossible to? grid in negative numbers, the answer must be 5.

SAT Math Practice Online Test Question No 3:

The ratio of a rectangle’s length to its width is 5:3. If its area is 60 square inches, find its width, in inches.

Because the ratio of length to width is 5:3, you can represent the length as 5x and the width as 3x. You know that area equals length × width, so the area = (3x)(5x), which equals 60. Simplifying, you get that 15 = 60, and then  = 4.

Mathematically, this result means that is either 2 or –2. It doesn’t make sense for a rectangle to have a negative dimension, so is 2. You’re looking for the width of the rectangle, which you called 3x and which you now know is 3(2) = 6.

SAT Math Practice Online Test Question No 4:

If ab = 4 and a + b = 5, what is the value of a2 + b2?

Watch out! Make sure you don’t fall into the trap where you think that (a + b)² =  + .

You need to FOIL to square a + b. If a + b = 5, you can solve for a, and determine that a = 5

SAT Math Practice Online Test Question No 5:

Hiring a band for a party involves a flat fee and an hourly fee. If it costs \$525 to hire a band for 3 hours, and \$765 to hire them for 5 hours, what is the flat fee, in dollars?

It costs \$525 to hire the band for 3 hours, and it costs \$765 to hire the band for 5 hours.

You can see that 2 extra hours of music costs an additional \$765 – \$525 = \$240, so each hour of music costs \$120. The \$525 is three times the hourly rate plus the flat fee (call the? flat fee? x), which can be represented as 525 = 3(120) + x.

Solve for x, and you learn that? the flat fee is \$165. You can double-check your answer by checking that the flat fee plus 5?hours of music costs \$765: 165 + 5(120) = 165 + 600 = 765.

SAT Math Practice Online Test Question No 6:

For all numbers g and h, let g & h be defined as [g2 + h2]/2. For what value of h does 4 & h = 26?

Following the pattern given in the definition of & in the problem, you know that 4 & h = [4² + h²]/2 = [16 + h²]/2, which you want to set equal to 26.

Multiplying both sides of the equation by 2, you get that 16 +  = 52, so  = 36.

This result means that h equals 6 or –6. The answer must be 6 because you can’t grid in negative numbers.

SAT Math Practice Online Test Question No 7:

If d is the middle number of three consecutive odd integers whose sum is s, what is the value of d divided by s?

Just pick three consecutive odd integers, like 1, 3, and 5. Since d is the middle of these, d = 3.

Since s is the sum of these, s = 1 + 3 + 5 = 9. So d divided by s is 3/9 or 1/3.

SAT Math Practice Online Test Question No 8:

The measures of the four angles in a quadrilateral have a ratio of 3:4:5:6. What is the measure, in degrees, of the smallest of these angles?

The sum of the four angles in a quadrilateral is 360 °. The sum of the parts in the ratio is 3 + 4 + 5 + 6 = 18.

Therefore the angles are 3/18, 4/18, 5/18, and 6/18 of the whole, which is 360°. So the smallest angle measures (3/18)(360°) = 60°.

SAT Math Practice Online Test Question No 9:

If x and y are positive integers such that x2 + y2 = 41, then what is the value of (x + y)2?

By guessing and checking positive integers, you should be able to see that the only positive integers that satisfy the equation are 5 and 4. Therefore (x + y)² =  (5 + 4)² = 81.

SAT Math Practice Online Test Question No 10:

NUMBER OF BOOKS READ DURING SUMMER VACATION The table above shows the number of books 20 students read over their summer vacation. What is the median number of books read by these students?
