The solution to the equation 8(2ˣ + 3) = 48 is x = 0.
Here, we have,
To solve the equation 8(2ˣ + 3) = 48, we can follow these steps:
Distribute the 8 to both terms inside the parentheses:
8 * 2ˣ + 8 * 3 = 48
Simplify the equation:
2⁽ˣ⁺³⁾ + 24 = 48
Subtract 24 from both sides to isolate the exponential term:
2⁽ˣ⁺³⁾ = 48 - 24
2⁽ˣ⁺³⁾ = 24
Rewrite 24 as a power of 2:
2⁽ˣ⁺³⁾ = 2³ * 3
Apply the property of exponentiation, where if two powers with the same base are equal, then their exponents must be equal:
x + 3 = 3
Solve for x by subtracting 3 from both sides:
x = 0
Therefore, the solution to the equation 8(2ˣ + 3) = 48 is x = 0.

a, b, and c represent three different digits. If you add up all of the six two - digit numbers that can be written with these digits, where you don't use the same digit twice in each number, then the sum will be 528. Find these digits.
Answer:
7, 8 and 9Step-by-step explanation:
Two-digit numbers are:
ab, ac, ba, bc, ca, cbSum of them is:
10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 52822a + 22b + 22c = 528a + b + c = 528/22a + b + c = 24The only option of three different digits with the sum of 24 is 7, 8 and 9
Answer:
The answer is 7, 8 and 9. The Two-digit numbers are: ab, ac, ba, bc, ca, cb
The Sum of them is: 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528
22a + 22b + 22c = 528
a + b + c = 528/22
a + b + c = 24 The only option/options of the three different digits with the sum of 24 is 7, 8 and 9.

A worker is spray painting doors. It takes LaTeX: \frac{2}{5} 2 5 of a can of spray paint to paint 1 door. The worker has 2 cans of spray paint total. How many doors can the worker paint? Group of answer choices
Answer:
5 doors
Step-by-step explanation:
Can of spray paint : door painted = 2/5 : 1
The worker has 2 cans of spray paint total.
How many doors can the worker paint?
Let x = number of doors the worker can paint
Can of spray paint : door painted
2 : x
Equate both ratios
2/5 : 1 = 2 : x
2/5 ÷ 1 = 2/x
2/5 × 1/1 = 2/x
2/5 = 2/x
Cross product
2 * x = 5 * 2
2x = 10
x = 10/2
x = 5 doors
The worker can paint 5 doors with 2 cans of spray paint

Answer:
[tex]y = \frac{1}{5}x +\frac{13}{5}[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (2,3)[/tex]
[tex](x_2,y_2) = (7,4)[/tex]
Required
Complete the equation y - 4.....
First, we need to determine the slope as follows:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{4 - 3}{7 - 2}[/tex]
[tex]m = \frac{1}{5}[/tex]
The equation is then calculated as thus:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - 4 = \frac{1}{5}(x -7)[/tex]
Open bracket
[tex]y - 4 = \frac{1}{5}x -\frac{7}{5}[/tex]
Add 4 to both sides
[tex]y - 4 +4= \frac{1}{5}x -\frac{7}{5} + 4[/tex]
[tex]y = \frac{1}{5}x -\frac{7}{5} + 4[/tex]
[tex]y = \frac{1}{5}x +\frac{-7+20}{5}[/tex]
[tex]y = \frac{1}{5}x +\frac{13}{5}[/tex]
Answer:
y - 4 = 1/5 ( x - 7 )

A couch costs $350 to make. Before it is sold, it is marked up in price 80% more. How much will the couch cost?
Answer:$630
Step-by-step explanation:
What is 80% of 350?
Y is 80% of 350
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 80% * 350
Converting percent to decimal:
p = 80%/100 = 0.8
Y = 0.8 * 350
Y = 280
then u add 280 to 350
You earn a new a weekly allowance of five dollars and your neighbor is paying you 7.50 per hour for shoveling the driveway how many hours,x, Master work this week if you wanna earn more than $30
Answer:
Hours of work= 3.5

Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework. He says that he spent 125% more time doing homework this week. Is he correct? Show your work to justify your decision. (5 points)
Answer:
[tex]\huge\boxed{\sf No}[/tex]
Step-by-step explanation:
Evan spent 20 hours doing homework last week
25 hours were spent this week.
Let's see what 125% of 20 equals:
= (125 / 100) * 20
= (125 / 10) * 2
= 125 / 5
= 25 hours
But,
It is written that Evan thought he spent 125 % more than the last week which means:
= (125% of 20) + 20
= 25 + 20
= 45 hours
He should've said that he has given 25% more time than the last week.
(Note that: 25 % of 20 equals 5 so 25 % more than last week will be equal to (25 % + 20) = (5+20) = 25)

Y is directly related to X, and Y is 81 when X is 27.
The constant of variation is ___
(there are no answer choices, it's just a type in box so i need an exact answer please! :))
Answer:
Since x and y are directly related, the equation for their comparison will look like
kx = y
where k is your constant. They give you an instance in the problem where x = 27 and y = 81. Plug this into the above equation and solve for k.
kx = y
k (27) = 81
k = 3
So, the constant of variation is 3.
A family bought a total of 32 adult and child tickets to eat at the dining hall.
Adult tickets are $21 each and children are $15 each.
The family paid a total of $282
Write an equation to model the total number of tickets sold.
Write an equation to model the cost of tickets sold.
How many of adult tickets, “x” and child tickets, “y” did they buy?
Answer:
Answer: 250 $3 tickets and 100 $2 tickets were sold.
Step-by-step explanation:
Solution:
Step 1: Set up a table with quantity and value.
quantity value total
$3 tickets
$2 tickets
together
Step 2: Fill in the table with information from the question.
The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?
Let x = number of $3 tickets
Let y = number of $2 tickets
Total = quantity × value
quantity value total
$3 tickets x 3 3x
$2 tickets y 2 2y
together 350 950
Step 3: Add down each column to get the equations
x + y = 350 (equation 1)
3x + 2y = 950 (equation 2)
Use Substitution Method
Isolate variable x in equation 1
x = 350 – y (equation 3)
Substitute equation 3 into equation 2
3(350 – y) + 2y = 950
1050 – 3y + 2y = 950
3y – 2y = 1050 – 950
y = 100
Substitute y = 100 into equation 1
x + 100 = 350
x = 250
Answer: 250 $3 tickets and 100 $2 tickets were sold.

PLEASE HELP!!! A $950 computeris on sale for 15% off. If sales tax is 6% will this computer cost including tax?
Answer:
the computer will cost 864.5
Step-by-step explanation:
15% of 950 is 142.5.
950-142.5=807.5
6% of 950 is 57
Answer:
$855.95
Step-by-step explanation:
So We can first multiply the original price by 0.85 becuase its 15 percent off and we’re paying 85 percent of the original price basically.
You’ll get 807.50.
Now to find the sales tax we multiply that by 1.06 becuase the 100 percent is the price now and we’re just adding 6 percent so 1.06, and you’ll get 855.95
So no adding and subtracting and that takes off 2 steps and its way quicker
So the final answer is $855.95
The graphed line shown below is y = 5 x minus 10.
On a coordinate plane, a line goes through (2, 0) and (3, 5).
Which equation, when graphed with the given equation, will form a system that has no solution?
y = -5 x + 10
y = 5 (x + 2)
y = 5 (x - 2)
y = -5 x - 10
Step-by-step explanation:
For 2 lines to form a system with no real solution, the slope of the lines have to be equal and the y-intercept is different.
Hence the answer is y = 5(x + 2).
