Can anyone help, please? -1.3 ≥ 2.9 -0.6r Graph the solution

1 answer:

3 0

Solving this kind of problem is easier if you take steps to make the coefficient of the unknown a positive one. Adding 0.6r to both sides makes the coeff. of r a positive one: 0.6r greater than or equal to 2.9+1.3.

0.6r then is equal to or greater than 4.2. Divide both sides by 0.6 to isolate r:

r greater than or equal to 7.

Let r be represented by the horizontal number line. Darken r = 7 and also darken the r axis to the right of r=7.

The sum of three consecutive natural numbers is 450 find the numbers. The three numbers in increasing order are?

pantera1 [17]

Answer: 149,150,151

Step-by-step explanation:

1.st solution

Let the smallest number is x.

So next consecutive number is x+1

So the third consecutive number is x+2

So the sum of these three numbers is:

x+x+1+x+2=450

3x+3=450

3x=447

x=149 - first number

Second number is 149+1=150

Third number is 150+1=151

2-nd solution

The sum of 3 numbers in row is 450. It means that average number is 450:3=150 - is the number which is in the middle

So the first one number is 150-1=149 and the third number is 150+1=151

3 ⅕ -⅔ divided by 2 ⅘

spin [16.1K]

Answer:

160/196

Step-by-step explanation:

it would be easier if you converted all fractions to improper fractions

so 3 1/5 would equal 16/5 and 2 4/5 would equal to 14/5

$\frac{14}{5} - \frac{2}{3}$ : to solve this you would need the same common denomenator,

to do this you can multiply 5 and 3 by something to make the lowest common denominator, which would be 15

thus

multiplying first fraction by 3 and the second by 5

42/15 - 10/15 = 32/15

now 32/15 divided by 14/5

the rule for dividing fractions, is flipping the fraction which you will be using to divide, and then multiplying it to the first fraction:

$\frac{32}{14}$ multiplied by $\frac{5}{14}$

thus, answer is 160/196

Triangle LMN has been dilated to form triangle L'M'N'. What is the least amount of information needed to determine if the two tr

artcher [175]

The least amount of information needed to establish congruence is; Angles M and M' are congruent, and angles N and N' are congruent.

<h3>What is the least amount of information needed to determine if the two triangles are similar?</h3>

If follows from concept of congruence that two triangles are congruent only if all three angle measures are congruent or all corresponding sides are in the same ratio.

Hence, when angles M, N and M', N' are established as congruent, it follows that the measures are equal respectively.

Ultimately, the measure of angles L and L' are equal and hence, all three angles are congruent in each triangle.

Therefore, the least amount of information needed is; Angles M and M' are congruent, and angles N and N' are congruent.
