4x + 3 = x + 2(x + 7)
step by step
Answer:
x=11
Step-by-step explanation:
4x + 3 = x+ 2x + 14
4x + 3 = 3 x + 14
4x - 3x = 14 -3
x= 14 - 3
x= 11
Answer:
x=11
Step-by-step explanation:
Distribute :
4x + 3 = x + 2( x+ 7)
4x + 3 = x + 2x + 14
Combine like terms :
4x + 3 = x + 2x + 14
4x + 3 = 3 x+ 14
Subtract 3 from both sides of the equation :
4x + 3 = 3x + 14
4x + 3-3 = 3x + 14 -3
Simplify :
what ever way you know how to subtract the numbers you should get this answer :
4x = 3x + 11
Subtract 3 from both sides of the equation :
4x = 3x + 11
4x - 3x = 3x + 11 - 3x
Simplify :
combine like terms
multiply by 1
combine like terms
x= 11

A train is 1000 metres long. It is travelling at a constant speed, and approaches a
tunnel that is 3000 metres long. From the time that the last car on the train has
completely entered the tunnel until the time when the front of the train emerges
from the other end 30 seconds pass.
Determine the speed of the train, in kilometres per hour.
Answer:
240kmh
Step-by-step explanation:
The distance that the train traveled in 30s is the difference of the total length of the tunnel and the train (2000m). This means it travels 2000m/30s. This ratio is the same as 240000/3600s or 240km/1hr.
The solution is, 240kmh is the speed of the train, in kilo-meters per hour.
What is speed?Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Speed = Distance/ Time.
here, we have,
given that,
A train is 1000 metres long. It is travelling at a constant speed, and approaches a tunnel that is 3000 metres long.
From the time that the last car on the train has completely entered the tunnel until the time when the front of the train emerges from the other end 30 seconds pass.
so, we get,
The distance that the train traveled in 30s is the difference of the total length of the tunnel and the train (2000m).
This means it travels 2000m/30s.
This ratio is the same as 240000/3600s or 240km/1hr.
Hence, The solution is, 240kmh is the speed of the train, in kilo-meters per hour.

I need help find this in slope intercept form
Answer:
y=2x+24 is you're answer
Answer:
I'm pretty sure it's y=2x+24
Step-by-step explanation:
The slope intercept formula is y=mx+b. So to get the equation into that form you would have to get y by itslef, which means you would have to subtract 8x from both side. And then you can't have a number in front of the y so you have to divide by that for all of the terms.This then gives you your answer.

Write the following quadratic expression in standard form: ( 2 x − 1 ) ( 3 x − 1 )
Answer:
6[tex]x^{2}[/tex] - 5[tex]x[/tex] + 1
Step-by-step explanation:
Standard form is: [tex]ax^{2} +bx+x[/tex]
To reach that you have to distribute:
(2x - 1) (3x - 1)
2x (3x - 1) = 6[tex]x^{2}[/tex] - 2[tex]x[/tex]
-1 (3x - 1) = -3[tex]x[/tex] + 1

For f(x) = 3x + 2, find f(3)
sub x = 3
f(3) = 3( 3 ) + 2
=9 + 2
=11
Answer:
f(3) = 11
Step-by-step explanation:
To evaluate f(3) substitute x = 3 into f(x) , that is
f(3) = 3(3) + 2 = 9 + 2 = 11

Mrs. Moore is making packages of art supplies for an art project. Each package contains sheets of white paper and blue paper. There are 84 sheets of blue paper and 96 sheets of white paper available to be used in the packages. Each package has the same number of blue paper. Each package has the same number of white paper. Mrs. Moore makes the maximum number of packages possible. There are no sheets of paper left over. What is the maximum number of packages that can be made and how many sheets of blue paper and white paper are in each package
Answer:
The maximum number of packages that can be made are 12 packages
The number of sheets of blue paper and white paper per package = 7 and 8 sheets respectively
Step-by-step explanation:
The number of sheets of blue paper available to Mrs. Moore = 84 sheets
The number of sheets of white paper available to Mrs. Moore = 96 sheets
The number of blue paper in each package = The number of white paper in each package
Therefore, the maximum number of packages that can be made is given by the Highest Common Factor, HCF, of 84 and 96 which is found as follows;
The prime factors of 84 = 2² × 3 × 7, from which we have;
Factors of 84 = 4 × 3 × 7 = 12 × 7
The prime factors of 96 = 2⁵ × 3, from which we have;
Factors of 96 = 4 × 8 × 3 = 12 × 8
∴ The HCF of 84 and 96 = 12
The maximum number of packages that can be made = Twelve packages
The number of sheets of blue paper in each package = Seven
The number of sheets of white paper in each package = Eight.

Starbucks sells 26 drinks every 2 hours. How many drinks would they sell in 12 hours?
Answer:
156 Drinks
Step-by-step explanation:
Answer:
No. of drinks sell by them in an hour=26/2=13
So,No. of drinks sell by them in 12 hours=
[tex]12 \times 13 = 156[/tex]
Hence, They sell 156 drinks in 12 Hours and 312 drinks in a day.
Gotta love these Starbucks lover, they'll tell you I'm insaneIf 5x - 2 = -12. then x =
Answer:
x = -2
Step-by-step explanation:
First let's solve the given equation.
5x - 2 = -12
Combine the constants by adding 2 to both sides.
5x = -10
Isolate x by dividing both sides by 5.
x = -2
This is your answer.
Check your answer by plugging x = -2 back into the equation.
5x - 2 = -12
5(-2) - 2 = -12
-10 - 2 = -12
-12 = -12
Your answer is correct.
Hope this helps!

An arithmetic sequence is represented by the explicit formula A(n) = 2 +(n − 1)(− 5)
What is the recursive formula?
Answer:
a+(n-1)d please do you get it or
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 5
Step-by-step explanation:
Given the explicit formula
A(n) = 2 - 5(n - 1)
Compare with the standard form
A(n) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = - 5
A recursive formula allows a term in the sequence to be found by adding d to the previous term.
Then recursive formula is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 5 , with a₁ = 2
