Solve the system of equations by graphing.

simone has discovered a blow out sale at a shop in the mall. the cost of the 2 sweaters , 5 shirts and 3 pairs of pants is 172.

Artyom0805 [142]

For this you will need to calculate the number of sweaters - 7x. Then you need to calculate the number of shirts - 9y. Last you need to calculate the number of pants - 12z. To balance the equation, you must calculate the total price $172+$269+$74 = $515. The equation is 7x+9y+12z = $515.

PLEASE HELP ME

nasty-shy [4]

Answer:

1) Sam's Club is better because the price for 10 cans at the village market would be $6.20 versus $4.70 from Sam's Club

2) 420 people with 210 per hour

3) It would be more beneficial to buy apples from the Quick Market considering the explanation below.

4) 396 quarts per hour and a daily rate of 792.

Step-by-step explanation:

1) $3.10 x 2 = $6.20

2) 70 x 6 = 420

so, 210 per hour

3) $1.05 divided by 3 is $0.35 per apple at the Quick Market

$2.55 divided by 5 is $0.51 per apple at the Stop and Save.

4) take 330 and divide by 10 to get the amount per hour which is 33 quarts per hour.

330 + 33 + 33 = 396 for 12 hours

396 x 2 = 792 for one day.

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3. 00 0. 50 m = 9. 5

Sliva [168]

The statement, which shows the meaning of the taxi driver’s equation for the mileage and fee formula are statement B and E.

<h3>What is linear equation or formula?</h3>

Linear equation or formula is the equation in which the highest power of the unknown variable is one.

Given information-

The formula equation for the mileage is,

$3.00+0.50m=9.50$

In the above formula the term m represents the number of miles traveled.

This formula written by the taxi driver shows the relation between the mileage and fee for his last customer. Using this expression the number of miles can be calculated as,

$3.00+0.50m=9.50$

Subtract with 3 both the sides,

$0.50m=9.50-3.00\\0.50m=6.50$

Divide by number 0.5 both the sides,

$m=\dfrac{6.5}{0.5}\\m=13$

Thus, his last costumer traveled 13 miles.

The 13 times 0.5 plus $3 is equal to the $9.50 which means nine dollars and fifty cents. Thus the option B is the correct option.

The number of miles traveled by customer is 13 miles. 13 miles of 50 cent is equal to $6.5. If we add three dollars in it the result will be equal to the nine dollars and fifty cents. Thus the option E is correct.

Hence, the statement, which shows the meaning of the driver’s equation, are,

B) Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

E) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Minimum point of the quadratic x^2+6x-2

WITCHER [35]

Answer:

(-3,-11)

Step-by-step explanation:

Compare the given quadratic equation with the general quadratic equation.

a=1, b=6 and c=-2

$x=-\dfrac{(6)}{2(1)}\\=-3$

Subsitute $-3$ for $x$ in given quadratic equation.

$y=(-3)^2+6(-3)-2\\=9-18-2\\=-11$

The minimum point is (-3,-11).

Which missing piece of information would allow the triangles in the figure to be proven congruent by AAS? answer: A) ∠C ≅ ∠L B)

anzhelika [568]

Answer:

B) ∠B ≅ ∠K

Step-by-step explanation:

The Angle-Angle-Side Postulate (AAS) states that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.

Given that ∠A ≅ ∠J and AC ≅ JL, then we need that ∠B ≅ ∠K to satisfy postulate AAS (the two angles are ∠A and ∠B in one triangle and ∠K and ∠J in the other one, and the non-included side is AC in one triangle and JL in the other one).
