Answer:

x

Step-by-step explanation:

-3x-5-2x>-25

Subtract the x terms:

-5x-5>-25

Add 5 to both sides:

-5x-5+5>-25+5

-5x>-20

Multiply both sides by -1 and flip the inequality symbol:

5x

Divide both sides by 5:

\frac{5x}{5}

x

Answer:

Option 1

Step-by-step explanation:

Step 1: Write inequality

  • -3x - 5 - 2x > -25

Step 2: Solve for <em>x</em>

  1. Combine like terms: -5x - 5 > -25
  2. Add 5 to both sides: -5x > -20
  3. Divide both sides by -5: x < 4

Find two consecutive odd integers whose product is 1443
liberstina [14]

Let's x represents the first odd integer

The next consecutive integer would be represented as x+2.

So x and x+2 being multiplied together will give us 1443:

(x)(x+2)=1443

x^2+2x=1443

x^2+2x-1443=0

By solving the quadratic equation using the quadratic formula, x will equal to 37 and -39.

Since the problem says "integers", so I'm assuming two pairs of consecutive integers would be ok.

With that said you 1st pair will be: 37,39

Your second pair will be: -37,-39.

Joel wants to fence off a triangular portion of his yard for his chickens. The three pieces of fencing he haas to use are 8 feet
Sedaia [141]

No, it will not be able to make a right triangle.

<em><u>Solution:</u></em>

Given that,

Joel wants to fence off a triangular portion of his yard for his chickens.

The length of three peices of fencing are 8 feet , 15 feet and 20 feet

For making it a right triangle it must satisfy the "Pythagorus theorem"

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

For a right angled triangle with sides a, b, c

c^2 = a^2+b^2

Given sides are:

a = 8 feet

b = 15 feet

c = 20 feet

Substituting the values in above formula

20^2 = 8 ^2+15^2\\\\400 = 64 + 225\\\\400\neq 289

Since the pythogoras formula is not satisfied, the given sides cannot form a right angled triangle

Thus , No, it will not be able to make a right triangle.

Jonathan weighs thirty pounds more than three times his son Aidan's weight.Their combined weight is 210 pounds.Write an equation
aalyn [17]
The equation should be
j = 30 + 3a
j + a = 210

Solving the equation
j + a = 210
(30 + 3a) + a = 210
30 + 4a = 210
4a = 180
a = 45

j = 30 + 3a
j = 30 + 3 × 45
j = 30 + 135
j = 165

Aiden's weight is 45 pounds, Jonathan's weight is 165 pounds
