Answer:

P = 37 in

Step-by-step explanation:

since the base angles of the triangle are congruent then the triangle is isosceles with the 2 legs congruent , then

3x - 2 = 2x + 4 ( subtract 2x from both sides )

x - 2 = 4 ( add 2 to both sides )

x = 6

then

2x + 4 = 2(6) + 4 = 12 + 4 = 16

3x - 2 = 3(6) - 2 = 18 - 2 = 16

the perimeter (P) is the sum of the 3 sides , then

P = 16 + 16 + 5 = 37 in

The answer for P is 37 in.

please help me this is due today

Answers

Answer:

Step-by-step explanation:

This problem is asking you to substitute for x.

1. 38.1 + x when x=-6.1

It is giving you what the value of x is, -6.1.

Substitute

38.1 - 6.1

=32

When ever it says x =

That number replaces x and then you solve.

2. 18.7 + x x = 8.5

18.7 + 8.5

27.2

Do this for the rest of the problems.

The answer is 34

Explanation:

Choose the graph that represents the following system of inequalities:

y ≥ −3x + 1
y ≥ 1 over 2x + 3

In each graph, the area for f(x) is shaded and labeled A, the area for g(x) is shaded and labeled B, and the area where they have shading in common is labeled AB.

Answers

Answer:

Step-by-step explanation:

Step1 : Remove the inequalities

Step2 : Finding intersection points of equations

By solving linear equation

Replacing value of x in any equations

we get,

Therefore, Point of intersection is (-0.5,2.5)

Step3: Test of origin (0,0)

Here, If inequalities holds true for origin then, shades the graph towards the origin.

For equation 1.

True, Shade graph towards origin.

For equation 2.

True, Shade graph towards origin.

Thus, Correct graph is C

the correct graph is c

Bob ate only 18 chocolate bars out of a new box of chocolates and left 2/5 of them because he started feeling sick. How many chocolates were in the full box?

Answers

Answer: explanation:

The chocolates were in the full box, if Bob ate only 18 chocolate bars out of a new box of chocolates and left 2/5 is 30.

What is a fraction?

A numerical value that designates a portion of a whole is used to represent fractions. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.

Given:

Bob ate only 18 chocolate bars out of a new box of chocolates and left 2/5,

Calculate the total chocolate as shown below

Total chocolate = T

T = 18 + 2 / 5 × T

T - 2 / 5T = 18

3 / 5 T = 18

3T = 18 × 5

T = 90 / 3

T = 30

Therefore, the chocolates were in the full box, if Bob ate only 18 chocolate bars out of a new box of chocolates and left 2/5 is 30.

How to use a pattern to find the product of a decimal

Answers

Answer:

A decimal sequence is a set of decimals that follow each other in order, and we use a rule, or pattern, to go from one number to the next. To find the rule for a sequence, we take two consecutive numbers and subtract them.

Answer:

Step-by-step explanation:

So I don't know if this will help or is the answer that you're looking for but here:

If you're multiplying a decimal by 1, it obviously stays the same.

ex: 1 x 0.25 = 0.25

If you multiply by 10 then you move the decimal place once to the right, as it gets bigger

ex: 10 x 0.25 = 2.5

you can do this for any number:

10 x 3.44 = 34.4

you can also use any power of 10.

10^2/100

100 x 2.75 = 275/275.0

Which graph represents the inequality 2.5 is less than the product of −0.5 and a number?

Answers

Answer: The mathematical statement is given as

"2.5 greater than the product of -0.5 and a number"

Product means times

So, we have the following representation

"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 greater than -0.5 * a number

Let the number be x

So, we have

"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 greater than -0.5x

Greater than is represented by >

So, we have

"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 > -0.5x

Next, we plot the graph of the inequality expression

Answers

Answer:

45/8

Step-by-step explanation:

You divide 3 3/4 by 1 1/2

First turn the mixed numbers into improper fractions.

Multiply the whole number by the denominator then add the numerator. Keep the denominator the same.

3 3/4:

3 x 4 = 12

12+3

= 15/4

1 1/2 :

1 x 2= 2

2+1

= 3/2

now you're dividing 15/4 by 3/2

My teacher always taught me KFC:

Keep, change flip

Keep:

Keep the first fraction don't change it. 15/4 stays the same.

Change:

Change the division sign to multiplication.

Flip:

Flip the last fraction to its reciprocal.

In this case instead of it being 3/2, it will be 2/3

Next

Multiply straight across

15/4 x 2/3

15 x 2 = 30

4 x 3 = 12

30/12

Simplified would be 5/2 as an improper fraction

2 1/3 as a mixed number

I am so sorry but I don't know how to explain the 2nd question without it making any sense, I hope someone else can for you! I hope I helped with the first one!

Answer:

Step-by-step explanation:

2 1/3 as a mixed number
