HELP ASAP!!!! WILL GIVE BRAINLIEST! Tamara bought yarn for $39 and 2 pairs of knitting needles. Her total cost for the yarn and knitting needles was $69. Tamara writes an equation that represents the cost of each pair of knitting needles. If k represents the cost of each pair of knitting needles, which statements about verifying the value of k are true?


CHECK ALL THAT APPLY


A.) Tamara should substitute k = 30 into the equation 39 + 2 k = 69.


B.) After she substitutes the correct value for k into the equation, Tamara should find that the left side of the equation is equal to the right side.


C.) Tamara should substitute k = 15 into the equation 39 + 2 k = 69.


D.) After she substitutes the correct value for k into the equation, Tamara should find that the left side of the equation is not equal to the right side.


E.) To verify the solution to the equation, Tamara multiplies the solution by 2 and then adds it to 39. Then, she checks that it is equal to 69.


F.) To verify the solution to the equation, Tamara adds the solution to 2 and then adds it to 69. Then, she checks that it is equal to 39.

What is the solution to the equation 5(x-3) = 2(x+3)?

Answers

Answer:
x = 7


General Formulas and Concepts:
Order of Operations: BPEMDAS


Step-by-Step Explanation:
Step 1: Define
5(x - 3) = 2(x + 3)

Step 2: Solve for x
1. Distribute: 5x - 15 = 2x + 6
2. Subtract 2x on both sides: 3x - 15 = 6
3. Add 15 on both sides: 3x = 21
4. Divide both sides by 3: x = 7

A package of nuts weights 3/4 of a pound. One serving size is 1/8 of a pound, how many servings in the package?

Answers

Answer: 6 servings

Step-by-step explanation:

One serving is 1/8 of a pound.

One package is 3/4 of a pound.

The number of servings therefore will be the number of times that 1/8 can go into 3/4.

= (3/4) / (1/8)

= (3/4) * (8/1)

= 6 servings

Which deal is better to buy 5.90 buy 3 books get one free book or 6 for 24.96

Answers

Answer:

6 for $24.96

Step-by-step explanation:

$5.90 * 3 = $17.70

Therefore 4 books would be $17.70 because you get one for free

$24.96/6 = $4.16

Therefore if you got 4 books it would be $16.64

So, buying 6 books would be cheaper.

calculate the estimate of the mean height of the students in cm and explain your answer

Answers

Step-by-step explanation:

we find the average height of each height first,

t¹= (120+124)/2

=244/2

=122

t²= (124+128)/2

t²= 252/2

t²= 126

t³= (128+132)/2

t³= 260/2

t³= 130

t⁴= (132+136)/2

t⁴= 268/2

t⁴ =134

t⁵= (136+140)/2

t⁵= 276/2

t⁵= 138

so multiplying each height by its frequency we can find the total height, so we have..

total height= (122*7)+(126*8)+(130*13)+(134*9)+(138*3)

= 854+1008+1690+1206+414

= 5172

mean height = total height/total frequency

= 5172/40

=129.3
