Answer 1

Answer:

It was difficult reading the question, as written. Check my assumptions.

Step-by-step explanation:

"five more than the product of two and a number,

decreased by seven"

---

Let the "number" be a.

We are told "five more than . ." means +5,

"the product of two and a number" means 2a,

"decreased by seven" mean -7

Put the statements together to obtain:

+5+2a-7

Simplify to 2a-2

Evaluate when a = 8:

2a-2

2(8)-2

16-2

= 14

Priya is making burgers for a party. She has 5 pounds of meat and uses 1/3 of a pound for one burger. How many burgers can priya make?

Answers

Answer: Priya can make 15 burgers with 5 pounds of meat

Step-by-step explanation:

Step 1

From Priya's receipe,

1 burger can be made from 1/3 of a pound of meat

How many burgers can be made from 5 pound of meat

Step 2 Using the equation below, that

1 burger = 1/3 pound of meat

Therefore 5 pounds of meat

5 x 1 / 1/3 = 5/(1/3)

= 5 x3 = 15 Burgers.

James and Sarah went out to lunch. The price of lunch for both of them was $60. They tipped their server
25% of that amount
How much did each person pay if they shared the price of lunch and the tip equally?

Answers

Answer:

$37.50

Step-by-step explanation:

$60 (meal) + $15 (tip) = $75

$75 ÷ 2 (# of people splitting the cost) = $37.50

Solve for x:
(a) 4x - 21 = 5 - 9x

Answers

Answer:

X = 2

Step-by-step explanation:

First we'll need to simplify this equation:

Add 9x on both sides:

13x - 21 = 5

Add 21 on both sides:

13x = 26

Divide 26/13

26/13 = 2

X=2

(You can check this yourself by plugging x into the equation)

Answer:

No solutions

Step-by-step explanation:

4(2r + 3) = 15r - 11 + 1 - 7r

Distribute:

8r + 12 = 15r - 11 + 1 - 7r

Combine like terms:

8r + 12 = 8r - 10

Same to both sides:

0r = -22

Answer:

See the attached

Step-by-step explanation:

y ≥ 0 - limits the region to first and second quadrantsx - y ≥ 1 ⇒ y ≤ x - 1 (region A on the graph)3x + 4y < 12 ⇒ y < - 4/3x + 4 (region B on the graph)

What is the equation of the axis of symmetry of the parabola y=-2x^2+8x-7?
x=.....

Answers

Answer:

Equation of axis of symmetry is x = 2

Step-by-step explanation:

The equation of the parabola is given as;

y = -2x² + 8x - 7

The equation of the axis of symmetry is given by;

x = -b/2a

In the parabola equation given and using letters of quadratic equation, we can say that;

a = - 2

b = 8.

c = -7

Thus;

x = -b/2a = -8/(2 × - 2)

x = 8/4

x = 2

Equation of axis of symmetry is x = 2
