Tamara bought yarn for $39 and 2 pairs of knitting needles. Her total cost for the yarn and knitting needles was $69. Tamara wri

tes 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.
Tamara should substitute into the equation . 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


Tamara should substitute into the equation . 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.

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.

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.

Which expression is equivalent to ​
True [87]

Answer:

2^{\frac{5}{12}}

Step-by-step explanation:

  • The original expression \sqrt{2^5} ^{\frac{1}{4}} can be transformed into (2^{\frac{5}{3}})^{\frac{1}{4}} : both expressions are equivalent, the root of certain number is equivalent to that number power at a fraction whose denominator is the index of the root. The simpliest example for this statement is \sqrt{x} =x^{\frac{1}{2}} (the squared root of x equals x raised at 1/2).
  • Now, the expression(2^{\frac{5}{3}})^{\frac{1}{4}} can be simplified by using the power of a power property, which simply states that if b\neq 0 and ((b)^n)^m=b^{n\times{m}}. In this case, then  (2^{\frac{5}{3}})^{\frac{1}{4}}=2^{\frac{5}{3}\times{\frac{1}{4}}}=2^{\frac{5}{12}}, which is the final expression.

One canned juice drink is 20% orange juice, another is 5% orange juice, how many liters of each should be mixed together in orde
gavmur [86]

Answer:

11 L of 20% juice and 4 L of 5% juice

Step-by-step explanation:

Let

x L = amount of 20% juice

y L = amount of 5% juice

<u>20% juice:</u>

Amount = x L

Amount of juice =0.2x L

<u>5% juice:</u>

Amount = y L

Amount of juice =0.05y L

<u>16% juice:</u>

Amount = 15 L

Amount of juice =0.16\cdot 15=2.4 L

We mixed x L of 20% juice with y L of 5% juice to get 15 L of 16% juice, so

x+y=15

and

0.2x+0.05y=2.4

From the first equation:

x=15-y

Substitute it into the second equation:

0.2(15-y)+0.05y=2.4\\ \\20(15-y)+5y=240\\ \\300-20y+5y=240\\ \\-20y+5y=240-300\\ \\-15y=-60\\ \\15y=60\\ \\y=4\ L\\ \\x=15-4=11\ L
