he run 20 feet. She writes and solves the equation 2l + 2w = 62 to find the width of the run.
Which statements are true of the solution? Check all that apply.

A. The value of w is 10 feet.
B. The value of w can be zero.
C. The value of w cannot be a negative number.
D. Substitution is used to replace the variable l with a value of 20.
E. The subtraction property of equality is used to isolate the term with the variable w.

The total cost of 5 doughnuts and 6 cookies at a bakery is $11.95.The cost of each cookie is $0.95.Select the equation and its s
lisabon 2012 [21]

The equation for the situation is 5x+6(0.95)=11.95

The solution to the equation is x=1.25

First, you must set up the equation.

5x+6(0.95)=11.95

Then, you must simplify the terms.

5x+5.7=11.95

Next, subtract 5.7 on both sides.

5x=6.25

Finally, divide 5 on both sides

x=1.25

a previous analysis of paper boxes showed that the standard deviation of their lengths is 15 millimeters. A packers wishes to fi
vladimir1956 [14]

Answer:

864.36 boxes

Step-by-step explanation:

In the question above, we are given the following values,

Confidence interval 95%

Since we know the confidence interval, we can find the score.

Z score = 1.96

σ , Standards deviation = 15mm

Margin of error = 1 mm

The formula to use to solve the above question is given as:

No of boxes =[ (z score × standard deviation)/ margin of error]²

No of boxes = [(1.96 × 15)/1]²

= 864.36 boxes

Based on the options above, we can round it up to 97 boxes.

During geometry class, students are told that ΔTSR ≅ ΔUSV. Marcus states that ΔTSR is mapped to ΔUSV by performing a rotation ab
Paha777 [63]

Answer: Both students are correct.

Explanation:

In rotation a shape is rotated about a fixed point and it does not affect its measurements. it only changes its position.

Now, When Marcus rotated the \triangle TSR  about point S then this process did not affect its shape and size this is why he got the \triangle USV which is congruent to the \triangle TSR.

In reflection, when a shape reflected across a line then its all points get reflected across this line. But it also does not affect the measurement of the shape.

So, when Sam mapped \triangle USV by the reflection of \triangle TSR then the measurement of the \triangle USV did not change. And, he also got the congruent triangle.

Thus, we can say that, Both Marcus and Sam are right.

Solve the system of equations -4+11y=15 x=2y
kondaur [170]
To solve this I will be using substitution

-4 + 11y = 15
solve for y so

-4 + 11y = 15
11y = 19

y = 19/11

x = 2(19/11)

19/11 x 2 = 38/11

x = 38/11

x = 38/11
y = 19/11

I hope this helps!
