The sum of two numbers is 44 and the difference is 12. What are the numbers

Mathematics
1 answer:
drek231 [11]3 years ago
7 0

Answer:

16 and 28

Step-by-step explanation:

x + y = 44                    

x - y = 12

x = 12 + y

x + y = 44

12 + y + y = 44

12 + 2y = 44

2y = 32

y = 16

x + y = 44

x + 16 = 44

X = 28

Which of the following statements is true about the graph and the shading of the inequality
andreyandreev [35.5K]

Answer:

The graph is a solid line, and the shading is above the line.

Step-by-step explanation:

Given

x + y \ge 1

Required

Describe the graph of the inequality

We have:

x + y \ge 1

Subtract x from both sides

y \ge 1-x

The sign \ge implies that the graph has a solid line

The sign \ge which means greater than or greater also implies that the upper region is shaded

David has a loyalty card good for a 19% discount at his local hardware store. What would his total in dollars and cents be, afte
Elina [12.6K]

Discounts are used to reduce the original price of an item.

David will pay $25 and 92 cents for an item of $32, before tax

The discount (d) is given as:

d =19\%

The price (p) of the item is given as:

p = \$32

So, the amount (A) paid before tax is calculated using:

A = p \times (1 - d)

Substitute known values

A = \$32 \times (1 - 19\%)

Express percentage as decimal

A = \$32 \times (1 - 0.19)

Subtract 0.19 from 1

A = \$32 \times 0.81

Multiply 32 and 0.81

A = \$25.92

Hence, David will pay $25 and 92 cents for an item of $32, before tax

A slow pitch softball diamond is actually a square 60 ft on a side. how far is it from home to second ​base?
krek1111 [17]
For this case we have a square whose sides are known and equal to 60 ft.
 We want to find the diagonal of the square.
 For this, we use the Pythagorean theorem.
 We have then:
 d^2 = 60^2 + 60^2&#10;&#10;d =  \sqrt{60^2 + 60^2}&#10;&#10; d =  \sqrt{3600 + 3600}&#10;&#10;d = \sqrt{2*3600}&#10;&#10;d = 60\sqrt{2}&#10;
 Answer:
 
from home to second ​base it is about:
 d = 60\sqrt{2} feet
