Answer:
3 is correct answer
Step-by-step explanation:
[tex]3(x - 2) + 5x = 18 \\ 3x - 6 + 5x = 18 \\ 8x - 6 = 18 \\ 8x = 18 + 6 \\ 8x = 24 \\ x = \frac{24}{8} \\ x = 3[/tex]
hope it helped you:)
Answer:
x=3
Step-by-step explanation:
3x-6+5x=18
add the same terms to both sides
8x-6=18
add the term again
8x-6+6=18+6
simpfly
8x=24
8x/8 24/8

If f(x) = 4x + 8 and g(x) = \/x + 4,
what is (fºg)(12)?
Answer: 24
Step-by-step explanation:
(fºg)(12) would be f(g(12))
Plug in 12 for g(x) = square root of (12+4) = 4
Plug 4 in f(x)
f(4) = 16 + 8
=24

Answer:
h = (A - 9)/6
Step-by-step explanation:
Step 1: Define
A = b² + 2bh
b = 3
Step 2: Substitute
A = (3)² + 2(3)h
Step 3: Evaluate and solve for h
A = 9 + 6h
A - 9 = 6h
(A - 9)/6 = h
Aisha has 3 pizzas. She is serving each person at a party 14 of a pizza. How many people can she serve at the party? Use the number line to help you solve the problem.[ Please help TwT]
Given:
Aisha has 3 pizzas.
She is serving each person at a party 1/4 of a pizza.
To find:
The number of people she can serve at the party.
Solution:
Let the number of people be x.
Number of pizzas is 3. So, each person get [tex]\dfrac{3}{x}[/tex] part of pizza.
It is given that each person get 1/4 of a pizza.
[tex]\dfrac{1}{4}=\dfrac{3}{x}[/tex]
Using cross multiplication, we get
[tex]1\times x=3\times 4[/tex]
[tex]x=12[/tex]
Therefore, the number of persons in 12.
Now, divide the number line in four equal parts between each pair of consecutive integers.
Then, count the marked points from 0 to 3 excluding 0. These points represent number of persons.

$ 2000
Step-by-step explanation:
Find the equation. You find the gradient by using the gradient formula (rise/run)
that would be
1600 - 800 over 40 - 20
800/20
m (gradient) = 40
Hence 40x ...
Answer:
See below
Step-by-step explanation:
Refer to attached
Using two of the points to determine the function:
(20, 800), (40, 1600)Function is:
y = mx + bFinding m and b:
m = (1600 - 800)/(40-20) = 800/20 = 40800 = 40*20 + bb = 0So the function is:
y = 40xFor x = 50, we get
y = 40*50 = 200050 l diesel costs $2000
Emanuel works as a car salesman. He makes $13 an hour plus a commission of 5% on all cars he sells. Last month he worked 40 hours and sold cars worth $120,000. How much did he make last month?
Answer:

Step-by-step explanation:
salary = hourly rate * hours + 5% of sales
salary = $13/hour * 40 hours + 0.05 * $120,000
salary = $520 + $6000
salary = $6520

s ( x ) = 2 - x² t ( x ) = 3xs ( t ( -7 ) ) = ?--------------------------
t (-7) = 3 * ( -7 ) = -21s ( t ( -7 ) ) = s ( -21 ) = 2 - ( -21 )² = 2 - 441 = - 439s ( t ( -7 ) ) = -439Brain can type 50 words per minute. He needs to finish typing his 700-word essay and already has 375 words typed. Write and solve an equation to determine the number of minutes (m) that it will take Brain to finish writing his essay. ( round your answer to the nearest tenth)
Answer:
Step-by-step explanation:
Every minute he types 50 words, so in 700 he types for 14 min. The next step is that there 375 words already done. So you take 700 and and subtract it by 375 and that is 7. Hope It helped you out

if 1 and -3 are the zeroes of the polynomial xcube - axsquare - 13x + b find the values of a and b
Step-by-step explanation:
f(x) = x³ - ax² - 13x + b.
f(1) = 1³ - a(1)² - 13(1) + b = 0
=> 1 - a - 13 + b = 0, b - a - 12 = 0.
f(-3) = (-3)³ - a(-3)² - 13(-3) + b = 0
=> - 27 - 9a + 39 + b = 0, 12 - 9a + b = 0.
Therefore, b - a - 12 = 12 - 9a + b. 8a = 24, a = 3.
=> b - (3) - 12 = 0, b = 15.
