por favor ayúdenme en esta ecuación: 5x-3x=6x-8
Answers
Hey there!
ANSWER: [tex]x=2[/tex]EXPLANATION:[tex]5x-3x=6x-8[/tex]
Combine like terms.
[tex](5x+-3x)=6x-8\\2x=6x-8[/tex]
Subtract 6x from both sides of the equation.
[tex]2x-6x=6x-8-6x\\-4x=-8[/tex]
In the last step, we will divide both sides by -4.

Answer:
[tex]x=-11[/tex]
Step-by-step explanation:
[tex]-1=\frac{\left(5+x\right)}{6}[/tex]
Switch sides:
[tex]\frac{\left(5+x\right)}{6}=-1[/tex]
Multiply both sides by 6:
[tex]\frac{6\left(5+x\right)}{6}=6\left(-1\right)[/tex]
[tex]5+x=-6[/tex]
Subtract 5 from both sides:

Simon is making a poster about friendship in his art class. He divides his poster into 3 equal parts. Simon writes the names of his friends all over each part. Simon uses 1 part for his neighborhood friends and 1 part for his friends from school.
What fraction of the poster does Simon use for his friends from school?
Answers
Answer:
1/3
Step-by-step explanation:
The most important thing to remember is that the poster is divided into three equal parts and 1 part of it is for his neighborhood friends and another one part of it is for his friends from school. The denominator would be three and the numerator would be the 1 part he uses for his friends from school.
What is the perimeter of a rectangle that
has a length of 9 cm and a width of 6
cm?
A. 54 sq. cm B. 54 cm
C. 30 cm
D. 30 sq. cm
Answers
Answer:
The answer is option CStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
l = 9 cm
w = 6 cm
Substitute the values into the above formula and solve
We have
P = 2(9) + 2(6)
= 18 + 12
We have the final answer as
P = 30 cmHope this helps you
Answer: d.30cm
Step-by-step explanation:
the formula for perimeter is P=2L+2W
Substitute the length and width
P= 2(9)+2(6)
Multiply
P= 18+16
Add
P=30
Add the unit
P= 30cm

Answers
Answer:
The measure of x = 45 degrees
Answer:
x is equal to 50.
Explanation:
The three lines intersect creating a triangle. All angle measures for triangles in Euclidean geometry must have a sum of 180 degrees. Because of the Vertical angles theorem, which states if two angles are opposite they are congruent, this means the angle across from 40 degrees is also 40 degrees. Since we know that the second angle is 90 degrees based on the right angle sign. By adding 40 and 90 you get a sum of 130. Now you subtract 130 from 180. This gives you 50 degrees. Since the Vertical angle theorem states two opposite angles are congruent we know the x is equal to 50 degrees.

6. -n + 7 - 2n + 5n - 3 = -6
Answers
Answer:
n = -5
Step-by-step explanation:
Step 1: Write equation
-n + 7 - 2n + 5n - 3 = -6
Step 2: Solve for n
Combine like terms: 2n + 4 = -6
Subtract 4 on both sides: 2n = -10
Divide both sides by 2: n = -5

Students of an elementary school can wear only red or blue shirts. In one class of 28 students, 7 students are wearing blue shirts today and the rest of the students are wearing red shirts. What is the ratio of students wearing blue shirts to students wearing red shirts in that class today? Select each correct answer. Question 1 options: 1:7 7:21 7:28 For every student wearing a blue shirt, there were 3 students wearing red shirts. For every student wearing a blue shirt, there were 4 students wearing red shirts. For every student wearing a blue shirt, there were 7 students wearing red shirts.
Answers
Answer:
7:21 For every student wearing a blue shirt, there were 3 students wearing red shirts.
Step-by-step explanation:
If there are 28 students and 7 are wearing blue shirts then the number of students wearing red shirts is 28 - 7 = 21 so 21 students are wearing red shirts.
That means the ratio of blue shirts to red shirts is 7:21
That also means that for every student wearing a blue shirt, 3 were wearing a red shirt.
