d = n + 10
d = 3n
d = n − 10
d = 3n
d = n + 10
n = 3d
d = n − 10
n = 3d

Answer:

answer C

There is a positive relationship between calories and sodium. The relationship is strong.

Step-by-step explanation:

The following is a correct interpretation of this value is option c. There is a positive relationship between calories and sodium. The relationship is strong.

Since

A nutritionist collects data from 25 popular breakfast cereals.

The value of r for the resulting scatterplot is 0.83.

So based on this, we can say that there should be the positive relationship between calories and sodium.

And, due to this, the relationship is considered to be strong.

Hence the option c is correct.

Answer: x = 61 and y = 29

Step-by-step explanation: In this problem, notice that we

have a transversal that intersects two coplanar lines at different points.

Let's start by finding the value of y.

In the diagram, 2y and 58 are corresponding angles and if two

parallel lines are cut by a trans. corr. <'s must be congruent.

So we can setup the equation 2y = 58.

Solving from here, we find that y = 29.

Now, notice that 58 and 2x form a straight angle or a linear pair.

When two angles form a straight angle, they are supplementary.

So we can setup the equation 2x + 58 = 180.

Solving from here, we find that x = 61.

Step-by-step explanation:

Operations With Fractions

Simplify the following operations:

[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)[/tex]

Convert the mixed fractions to improper fractions:

[tex]\displaystyle 5\frac{1}{4}= 5+\frac{1}{4}=\frac{21}{4}[/tex]

[tex]\displaystyle 7\frac{1}{2}=7+\frac{1}{2}=\frac{15}{2}[/tex]

Substituting:

[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=-\frac{21}{4}-\left(-\frac{15}{2}\right)[/tex]

Simplifying:

[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=-\frac{21}{4}+\frac{15}{2}[/tex]

Amplifying the second fraction by 2:

[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=-\frac{21}{4}+\frac{30}{4}[/tex]

Adding both fractions:

[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=\frac{9}{4}=2\frac{1}{4}[/tex]

System A should be solved by elimination because you can easily cancel out the 3m to solve.

System B should be solved by substitution.  Since the an equation for the y value is given, you can easily substitute it into the other equation.

System C should be solved by graphing.  You don't have to worry about any slopes or intercepts to graph.  You can graph it using only whole numbers.

Step-by-step explanation:

It means that the point (6,2) is on both graphs at the same time. In short, it is the intersection point of the two graphs.

Algebraically, the ordered pair (x,y) = (6,2) makes all of the equations in the system to be true equations. A true equation is one where it simplifies to have the same number on both sides.

A system with at least one solution is considered a consistent system. If there is only one solution, then the system is also considered independent.

-3° C < 1°C is the correct option.

Step-by-step explanation:

As we know that:

If someone says that something is cooler than the other thing, it indicates that it is lesser than the other based on its temperature.

As the ice cream at −3°C is cooler than ice cream at 1°C, it indicates that temperature -3° C < temperature  1°C.

Therefore, -3° C < 1°C is the correct option.

Answer:

6 1/2

Step-by-step explanation:

To double the recipe we would need to multiply all the ingredients by 2. But since it is asking about the peaches, we only need to multiply 3 1/4 by 2. First we make the 3 1/4 to an improper fraction. (multiply denom. by the 3 then add the numerator. then keep the same denominator). The improper fraction of 3 1/4 would be 13/4. Now we can multiply by 2. That would give us 26/4 which reduces to 13/2. To change this back to a mixed number, we divide 13 by 2. That would give us 6 with a remainer of 1. So our answer is 6 1/2.

Note that Cheryl wants to find the number of hours seventh grade boys and girls spend on homework each week.

There are multiple causes of a biased sample.  Two of the most obvious ones I find are:

1.  She's surveying girls, but she is trying to get data on the number of hours all seventh graders (boys and girls) spend.

2. She's surveying 50 girls from the entire school, although she is trying to get data on seventh graders only.

Step-by-step explanation:

The value of the expression b²+ c², when b = 2 and c = –3, is 13.

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Given:

We have an expression,

b²+ c².

The value of the expression when b = 2 and c = –3,

= (2)²+ (-3)²

= 4 + 9

= 13

Therefore, the value is 13.
