Answer:

46%

Step-by-step explanation:

$\frac{23}{50} = \frac{x}{100}$

Cross Multiply

23 x 100 = 50x

2300 = 50x

$\frac{2300}{50} = \frac{50x}{50}$

The sum of two numbers is -18. If the first number is 10, which equation represents this situation, and what is the second numbe

professor190 [17]

Answer:

The equation that represents this solution is: 10+x= -18

The second number is -28.

Step-by-step explanation:

To solve for this, we first need to make an equation. We know that one of the numbers, the first one, is 10, but the second is unknown. Because of this, we will label the unknown number x. We also know that the -18 is the sum, so we know it will be behind the equal sign. Using this info, we can make the following equation.

10+x= -18

We did 10 because it was the first, added it with the unknown x, and it all equals -18. This would be your equation.

To find the answer, you need to solve the equation.

10+x= -18

First, since we are adding ten to both sides, subtract ten from both sides.

10-10+x= -18-10

Now, solve. Remember that subtracting a positive number is the same as adding a negative number.

x= -28

Now, check. Does 10+ -28 equal -18? Yes, so we are correct.

A rectangular piece of plywood has a diagonal which measures two feet more than the width. The length of the plywood is twice th

Nina [5.8K]

Answer:

The length of the diagonal = 3.6 feet

Step-by-step explanation:

* Lets change the story problem to equation to solve it

- Diagonal in a rectangle is the line which joining two

opposite vertices in it

- The diagonal , the length and the width formed together right

angle triangle where the diagonal is the hypotenuse of the

triangle and the length, the width are the two legs of the

right angle

- The length of the diagonal d is √(l² + w²) ⇒ Pythagoras theorem

∴ d² = l² + w²

- The diagonal is 2 feet more than the width

∴ d = w + 2

- The length is twice the width

∴ l = w

* Lets substitute the value of d and l in the equation of Pythagoras

∴ (w + 2)² = (2w)² + w² ⇒ solve the bracket

∴ w² + 4w + 4 = 4w² + w² ⇒ collect them in one side and add like term

∴ 4w² + w² - w² - 4w - 4 = 0 ⇒ add the like term

∴ 4w² - 4w - 4 = 0 ⇒ divide all term by 4

∴ w² - w - 1 = 0 ⇒ solve the quadratic using the formula

- In ax² + bx + c = 0

$x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}$

∵ a = 1 , b = -1 , c = -1

∴ $x=\frac{-(-1)+\sqrt{(-1)^{2}-4(1)(-1)}}{2(1)}=\frac{1+\sqrt{5}}{2}=1.6feet$

-The value of the width is 1.6 feet

∴ The length = 1.6 × 2 = 3.2 feet

∴ The length of the diagonal = 2 + 1.6 = 3.6 feet

Answer:

y ≥ x - 2 and x + 2y < 4

Step-by-step explanation:

There are two lines graphed.

The dotted line passes through (0,2) and (4,0), then:

slope (m): (0 - 2)/(4 - 0) = -1/2

y-intercept (b): 2

equation:

y = mx + b

y = -1/2x + 2

multiplying by 2 at both sides, we get

2y = -x + 4

x + 2y = 4

The inequality is x + 2y < 4 because points below this line are shaded and points on the line are not included.

The solid line passes through (0,-2) and (2,0), then:

slope (m): (0 - (-2))/(2 - 0) = 1

y-intercept (b): -2

equation:

y = x - 2

The inequality is y ≥ x - 2 because points above this line are shaded and points on the line are included.
