Answer:

(23, 4)

Step-by-step explanation:

If we use substitution, we need to rewrite the 2nd equation so we can substitute it into the first.

Step 1: Rewrite 2nd equation

x = 5y + 3

Step 2: Substitution

2(5y + 3) - 5y = 26

Step 3: Distribute

10y + 6 - 5y = 26

Step 4: Combine like terms

5y + 6 = 26

Step 5: Isolate <em>y</em>

5y = 20

y = 4

Step 6: Find <em>x</em>

x - 5(4) = 3

x - 20 = 3

x = 23

And we have our final answer!

Answer:

(23,4)

Step-by-step explanation:

x-5y=3

+5y=+5y

x=3+5y

-- Plug that into X for the other Equation

2(3+5y)-5y=26

Solve for y

2(3+5y)-5y=26

Distribute the 2

6+10y-5y=26

Simplify

6+5y=26

-6 =-6

5y=20

(divide by 5)

y=4

plug 4 in the either equation and solve for x

x-5(4)=3

x-20=3

+20=*20

X=23

Suppose that the original price of a short is 40$ which is better 60% discount of a discount of 30 followed by a discount of 35

kotykmax [81]

Answer:

60% discount is the better buy

Step-by-step explanation

Step one

Original price =$40

Let us compute the various discounts and compare the prices

For 60%

=60/100*40

=0.6*40

=$24

New price = 40-24= $16

For 35%

=35/100*40

=0.35*40

=$14

New price = 40-14= $26

A marketing research company desires to know the mean consumption of milk per week among people over age 30. They believe that t

Nitella [24]

Answer:

651 is the minimum number of people over age 30 they must include in their sample.

Step-by-step explanation:

We are given the following information:

Confidence level = 90%

Significance level = 10%

Maximum error = 0.09

Variance = 1.96

$\text{Standard Deviation} = \sqrt{\text{Variance}} = \sqrt{1.96} = 1.4$

Formula:

$\text{Error} = z_{critical}\dfrac{\sigma}{\sqrt{n}}$

Putting all the values,

$z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.64$

$0.09 = 1.64\times \dfrac{1.4}{\sqrt{n}}\\\\n = (\dfrac{1.64\times 1.4}{0.09})^2 = 650.81 \approx 651$

651 is the minimum number of people over age 30 they must include in their sample.

Solve for all missing measures

Answer:

Step-by-step explanation:

Begin

If this is a rhombus then <8 = 90 degrees as do all the central angles. That's because the diagonals intersect at right angles.

<4 = 38 z formation for parallel lines.

<7 = 52 The angles are part of a right angle triangle. <7 +38 = 90

<2 = 52 z formation of parallel lines (a rhombus has ll lines).

<3 = 38 The diagonals of a rhombus bisect each other.

<5 = 38 z formation for parallel lines.

<6 = 52 The diagonals of a rhombus are angle bisectors.

<1 = 52 The diagonals of a rhombus are angle bisectors.
