ATLAS Grade 7 Expressions and Equations Practice

What the test measures

Expressions and Equations skills

Use properties of operations to generate equivalent expressions
Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form
Use variables to represent quantities in a real-world or mathematical problem
Solve word problems leading to equations of the form px + q = r and p(x + q) = r
Solve and graph inequalities
Understand that rewriting an expression in different forms can reveal the way quantities are related

Standards basis

Arkansas Academic Standards for Mathematics (CCSS-M–aligned / Arkansas-adopted math standards) — Arkansas

How the ATLAS reports it

Arkansas’s statewide assessment system is ATLAS, which the ADE page says began serving in spring 2024. The official public page does not publish a math blueprint there, so the most defensible coverage map is the Arkansas math standards structure that ATLAS is aligned to.

Blueprint & weighting

ATLAS uses the Independent / state-specific framework (by grade domains structure).

A library reading room must keep noise at a level of at most $65.0$ decibels. A meter shows $68.5$ decibels. What is the minimum decrease needed in the noise level, in decibels, so that the room meets the rule?

The noise level must be at most $65.0$ decibels. The minimum decrease is $68.5 - 65.0 = 3.5\textsf{.}$

What value of $n$ satisfies $5n - 8 = 17$ ?

Add $8$ to both sides: $5n = 25$ . Divide both sides by $5$ : $n = 5$ .

In a school zone, a car must travel at a speed of at most $35.0$ miles per hour. A car is traveling at $38.2$ miles per hour. What is the minimum decrease needed in the car's speed, in miles per hour, so that it meets the speed limit?

The speed must be at most $35.0$ miles per hour. The minimum decrease is $38.2 - 35.0 = 3.2\textsf{.}$

Solve for $x$ : $6x - 1 = 17$ .

Subtract $-1$ from both sides: $6x = 18$ . Divide by $6$ : $x = 3$ .

A shipping company accepts a package only if its mass is at least $2.50$ kilograms. A package has a mass of $2.15$ kilograms. What is the minimum increase needed in the package's mass, in kilograms, so that it can be accepted?

The mass must be at least $2.50$ kilograms. The minimum increase is $2.50 - 2.15 = 0.35\textsf{.}$

Solve for $x$ : $x + 5 = -3$ .

Subtract 5 from both sides: $x = -8$ .
