PARCC evidence statement(s) tested: HS.D.1-1:
Solve multi-step contextual problems with degree of difficulty appropriate to the course, requiring application of knowledge and skills articulated in 7.RP.A, 7.NS.3, 7.EE, and/or 8.EE.
The evidence statement above references mainly Math Practice 4 in the Common Core:
[MP.4] Model with mathematics. Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace. … By high school, a student might use geometry to solve a design problem or use a function to describe how one quantity of interest depends on another. Mathematically proficient students who can apply what they know are comfortable making assumptions and approximations to simplify a complicated situation, realizing that these may need revision later. They are able to identify important quantities in a practical situation and map their relationships using such tools as diagrams, two-way tables, graphs, flowcharts and formulas. They can analyze those relationships mathematically to draw conclusions. They routinely interpret their mathematical results in the context of the situation and reflect on whether the results make sense, possibly improving the model if it has not served its purpose.
It may also reference other standards of mathematical practice, including MP.1 (make sense of problems and persevere in solving them), MP.2 (reason abstractly and quantitatively), and MP.5 (use appropriate tools strategically).
The question requires students’ prior understanding of the eighth-grade Common Core standard 8.EE.C, found under Expressions and Equations (analyze and solve linear equations and pairs of simultaneous linear equations), which states that they should be able to [EE.C.7] “solve linear equations in one variable” and [EE.C.8] “analyze and solve pairs of simultaneous linear equations.”
Note that the PARCC question referenced here simply uses understanding of these standards from eighth grade, considering this understanding to be securely-held knowledge. The PARCC question in Algebra 1 tests students’ ability to model with mathematics, as referenced in Math Practice 4.

Michelle lives 4.5 miles from work. Kelly lives 5.6 kilometers from work. Staci lives 4,200 meters from work. Kyle lives 670,000 centimeters from work.
Answer:
Michelle < Staci < Kelly < Kyle
Kyle is the greatest distance from work, while Michelle is the closest to work.
Step-by-Step Explanation:
1 kilometer = 0.62137119 mile(s)
4.5 miles = 0.62137119 × 4.5 = 2.79617036 kilometers
4,200 meters = 4.2 kilometers
670,000 centimeters = 6.7 kilometers
So,
Michelle = 2.8 kilometers (rounded up)
Kelly = 5.6 kilometers
Staci = 4.2 kilometers
Kyle = 6.7 kilometers
So,
Michelle < Staci < Kelly < Kyle
Kyle is the greatest distance from work, while Michelle is the closest to work.

Step-by-step explanation:
I hope this helps!
Hey again!
The answer to your question is 2 cm = 1 mile
We can solve this by doing 9/4.5, and we get 2. This means that every 2 centimeters in the scale drawing is equal to 1 mile in the actual.

There are 96 girls and 72 boys who want to participate in 6th grade intramurals .If each team has the same number of girls and the same number of boys,How many boys and girls will be on each team?
Answer:
by taking Hcf of 96 and 72 we get 4 so each team have 4
'24' teams can be made with each team having 4 girls and 3 boys.
Given that,
No. of girls = 96
No. of boys = 72
Since the number of teams is not given, we will find by finding out the GCF(Greatest Common factor) of 96 and 72.
96 = 2 * 2 * 2 * 2 * 2 * 3
72 = 2 * 2 * 2 * 3 * 3
GCF = 2 * 2 * 2 * 3 = 24
Thus, a maximum of 24 teams can be formed. The number of girls and boys in each of these teams would be:
No. of girls in each team = Total girls/no. of teams
= 96/24
= 4 girls
No. of boys in each team = Total boys/no. of teams
= 72/24
= 3 boys
Thus, each team will have 4 girls and 3 boys.

3(x+4) what is this question?
Answer:
Step-by-step explanation:
3×x+4×3
3x+12
Answer:
Step-by-step explanation:
The first step would be to multiply out the bracket. So, using this example we would times each item inside the bracket by 3.
As a result we would get: 3x + 12 = 18
Then we would need to move the 'x' value to one side of the equation and the rest of the equation to the other side. To move '12' onto the other side of the = sign we need to subtract 12 from both sides.
This would then bring us to: 3x = 6
Finally, to find the value of 'x' we then need to divide both side of the equation by 3.
Resulting in the final answer of x = 2

Answer: 6.50 I think
Step-by-step explanation:
I took 32/5=6. 6*5=30 which left 2. I divided that by 4 which gave me .50 that's how I got 6.50. I got the 5 because it takes 5 of the 20% to make 100%
solve the inequality
1/3x+8≤11
Answer:
x ≤ 9
Step-by-step explanation:
First, Isolate the variable by subtracting 8.
1/3x<= 3
Multiply both sides by 3
x<= 9
Answer:
x≤9
Step-by-step explanation:
Step 1: Subract 8 from both sides.
1/3x+8-8≤11-8
1/3x ≤3
Step 2: Multiply both sides by 3.
3*(1/3x)≤(3)*(3)
x≤9

The points (0,5) and (1,9) fall on a particular line. What is its equation in slope-intercept
form?
Answer:
y = 4x + 5
Step-by-step explanation:
First let's find its slope.
(5-9)/(0-1) = 4.
So far, in the equation we have y=4x+b.
As for the y-intercept, the coordinate (0,5) is the y-intercept.
Therefore, the equation in slope intercept form would be y=4x+5.
