6x+11=3x-1, what is x
Answer:
[tex]x=-4[/tex]
Step-by-step explanation:
[tex]6x+11=3x-1[/tex]
To solve this equation, we must first minus(subtract) 3x from both sides of the equation.
[tex]6x+11-3x=3x-1-3x[/tex]
And this equals:
[tex]3x+11=-1[/tex]
Now we must subtract again, but 11 times now.
[tex]3x+11-11=-1-11[/tex]
And this equals:
[tex]3x-12[/tex]
Now let's make this into a fraction to divide.
[tex]\frac{3x}{3}[/tex]
We get [tex]\frac{-12}{3}[/tex]
Now we got our answer:
[tex]x=-4[/tex]
Hope this helps!
Answer:
-4
Step-by-step explanation:
First you wanna subtract the 1 from the 11 then add subtract the 3x from the 6x and you should have 3x = -12 the. You just divide -12 by 3

Angie and Kenny play online video games. Angie buys 1 software package and 1 month of gameplay. Kenny buys 2 software packages and 3 months of gameplay. Each software package costs $50. If their total cost is $218, what is the cost of one month of gameplay?
Answer:
The cost of one-month gameplay is $39.33 or 39.
Step-by-step explanation:
Let the cost of one month = x
The cost of software = $50
The total amount that can be spent = $218
Therefore, we have to find the cost of one month of game play. Here is the following equation.
218 = (50 + x) + (50 + 2x)
218 = 100 + 3x
218 – 100 = 3x
118 = 3x
x = 118 / 3
x = 39.33 or 39
thus, the cost of one-month gameplay is $39.33 or 39.

14 +18 - 2 x 18 -7
Answer:
-11
Step-by-step explanation:
BIDMAS
(BRACKETS, INDICES, DIVISION, MULTIPLICATION, ADDITION, SUBTRACTION)
14 + 18 - 2 x 18 -7
the first thing we do is the multiplication (since there is no division in this question)
14 +18 − (2)(18) −7
14 + 18 - (36) - 7
32 - 36 - 7 = -11

-3/4 x + 1/2 = 3/4 solve for x please
Answer:
[tex]x = -\frac{1}{3}[/tex]
Step-by-step explanation:
1/2 = 2/4Plug 2/4 in: -3/4x + 2/4 = 3/4Subtract 2/4 from each side, so it now looks like this: -3/4x = 1/4Divide each side by -3/4, so it cancels out the -3/4 next to x. It should now look like this: x = -1/3I hope this helps!

{3x+y=10
{X-4y=-1 You must solve for Y
Answer:
x = 3 and y = 1
Step-by-step explanation:
Solve the following system:
{3 x + y = 10
x - 4 y = -1
Express the system in matrix form:
(3 | 1
1 | -4)(x
y) = (10
-1)
Solve the system with Cramer's rule:
x = 10 | 1
-1 | -4/3 | 1
1 | -4 and y = 3 | 10
1 | -1/3 | 1
1 | -4
Evaluate the determinant 3 | 1
1 | -4 = -13:
x = 10 | 1
-1 | -4/(-13) and y = 3 | 10
1 | -1/(-13)
Simplify 10 | 1
-1 | -4/(-13):
x = -1/13 10 | 1
-1 | -4 and y = 3 | 10
1 | -1/(-13)
Simplify 3 | 10
1 | -1/(-13):
x = -(10 | 1
-1 | -4)/13 and y = -1/13 3 | 10
1 | -1
Evaluate the determinant 10 | 1
-1 | -4 = -39:
x = (-1)/13×-39 and y = -(3 | 10
1 | -1)/13
(-1)/13 (-39) = 3:
x = 3 and y = -(3 | 10
1 | -1)/13
Evaluate the determinant 3 | 10
1 | -1 = -13:
x = 3 and y = (-1)/13×-13
(-1)/13 (-13) = 1:
Answer: x = 3 and y = 1

A students regular desk is 30 inches long and 18 inches wide. The teachers desk is similar to the student desk and has a length of 50 inches. What is the width of the teachers desk?
Answer:
Width of Teacher desk = 30 in
Step-by-step explanation:
Given:
Length of student desk = 30 in
Width of student desk = 18 in
Length of teacher desk = 50 in
Find:
Width of Teacher desk
Computation:
Assume,
Width of Teacher desk = x
Teacher desk is similar to student desk
Length of student desk / Width of student desk = Length of teacher desk / Width of Teacher desk
30 / 18 = 50 / x
x = [(50)(18)] / 30
Width of Teacher desk = 30 in

Find the area of triangle ABC.
A number is 2 /5 times another number. Their sum is 70. Find the numbers.
Answer:
50,20
Step-by-step explanation:
let the two numbers be x and y respectively.
According to the question,
y=2/5 times of x
Or,
y= 2x/5 ..........(1)
Again,
or, x+y=70
or, x+2x/5=70
or, (5x+2x)/5=70
or, 7x=350
therefore x=50
putting the value of y in equation (1)
y=2x/5
y= (2×50)/5
therefore, y=20
Answer:
x = 175
Step-by-step explanation:
given:
A number is 2 /5 times another number. Their sum is 70.
find: the numbers (coefficient)
solution:
cross multiply
2 ( x ) = 70
5
2 (x) = 70 (5)
2 (x) = 350
x = 350
2
x = 175
check:
2 ( x ) = 70
5
2 ( 175 ) = 70
5
350 = 70
5
70 = 70

How many solutions exist for the equation 5(x-1)+2 = 2x+3x-3 ?
Answer:
infinite number of solutions
Step-by-step explanation:
Given
5x - 1) + 2 = 2x + 3x - 3 ← distribute and simplify
5x - 5 + 2 = 5x - 3, that is
5x - 3 = 5x - 3
Since both sides are equal then there are an infinite number of solutions to the equation.

This is wrong, I used this answer too and it was wrong.
Step-by-step explanation:
2x + 3 = -7
What is the answer?
Answer:
x = -5
Step-by-step explanation:
Original Equation: 2x + 3 = -7
Subtract 3 from both sides:
2x + 3 - 3 = -7 - 3
Simplify:
2x = -10
Divide both sides by 2:
[tex] \frac{2x}{2} = \frac{ - 10}{2} [/tex]
Simplify:
x = -5

If tn is 2n+3 find t7 t30 and s10
Answer: t₇ = 17 t₃₀ = 63 S₁₀ = 140
Step-by-step explanation:
t₇ = 2(7) + 3
= 14 + 3
= 17
t₃₀ = 2(30) + 3
= 60 + 3
= 63
S₁₀ = (t₁ + t₁₀)/2 × 10
= (5 + 23)/2 × 10
= 28/2 10
= 14 × 10
= 140
6. Two trains traveled from opposite
directions on parallel tracks toward
the bullfight town. They started
1,110 km apart at exactly the same
time. Train A's speed was 55 km/h
and Train B's speed was 85 km/h.
Would the trains have
met within 5 hours?
Answer:
They will not have met
Step-by-step explanation:
Train A will have traveled 275km in 5 hours and Train B will have traveled 425km in 5 hours. This means that they will be 700km closer to one another but still 400km apart
