Greetings from Brasil...
Exponential equation - objective: to make the bases of the 1st and 2nd members equal
24 = 3 · 2ˣ let's move from 3 to the 1st member
24 ÷ 3 = 2ˣ
8 = 2ˣ simplifying 8: 8 = 2³
2³ = 2ˣ as the bases are the same, we work only with exponents

What should happen to both sides of the equation to isolate the variable?
Answer:
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable
Step-by-step explanation:
The m∠B is two more than three times the measure of ∠C. If ∠B and ∠C are complementary angles, find the measures of both angles.
Answer:
m∠B= 67
m∠C= 23
Step-by-step explanation:
okay so same thing we did before except they will equal 90 not 180
B= 3(c)+2
c+b=90
c+3(c)+2=90
4c+2=90
4c=92
c=23
now input them! or subtract!
90-23=67
m∠C=23
m∠B=67
Bridal Solutions, which sells European wedding dresses, has the following weekly
revenue and cost functions:
R(d) = 12000
C (d) = 350d + 5000
where R (d) represent the weekly revenue for selling d wedding dresses and
C(d) represent the weekly cost for selling d wedding dresses.
Answer:
Step-by-step explanation:
Given the weekly revenue and cost function
R(d) = 12000
C (d) = 350d + 5000
A firm break even point occurs when the amount of revenue is equal to the cost.
If the company Bridal solution breaks even then C(d) = R(d)
350d + 5000 = 12000
350d = 12000 - 5000
350d = 7000
divide both sides by 350
350d/350 = 7000/350
d = 20
Hence the total number of wedding dressing to be sold by Bridal Solutions for them to break even is 20 dresses.

8 − a = 17. What does a equal?
Answer:
a = -9
Step-by-step explanation:
8 - a = 17
8 -17 = a
-9 = a
Answer:
-9
Step-by-step explanation:
subtract 8 from both sides. divide -1 by both sides it gives you -9. When put into the equation the two negatives make a positive and you add 8 + 9 which gives u 17.

How do you write 3.8 in scientific notation?
Answer:
3.8 × 10^{1}
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Follow the steps below to see how 38 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 38
New Number: 3.8
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 3 . 8
Decimal Count: 1
There are 1 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 3.8
b = 1
Now the whole thing:
3.8 x 10^{1}
Step 4
Check work:
10^{1} = 10 x 3.8 = 38
Write the equation in slope-intercept form.
5x + 3y = 11
Answer:
y = -5/3 x + 11/3
Step-by-step explanation:
5x +3y = 11
3y = 11 - 5x
y = -5/3 x + 11/3
How do you graph y=-3x+2 y=2x-3

2x/x-5 = 4 (solve this equation)
If possible, do please tell me on how to do these kind of questions! <3
Answer:
x=10
Step-by-step explanation:
(2x)/(x-5)=4
first you multiply the denominator on both sides
2x=4(x-5)
then multiply
2x=4x-20
then move all the x variables to one side and the constants to the other with subtraction and addition
20=2x
divide and you get x=10
you can plug this in to check your work and you'll see: (2(10))/(10-5)=4 or 20/5=4 which you know is true

There are 8 girls and 5 boys on the math team. Which ratio correctly describes the relationship between boys and girls
on the math team?
Answer:
If boys to girls, 5:8. If girls to boys, 8:5.
Step-by-step explanation:
There are 8 girls and 5 boys. That means the ratio could be 8:5 or 5:8. You didn't specify in the question which one, so I can't tell you which one. But, if the question asks for boys to girls, put 5:8. If it asks for girls to boys, but 8:5.
Find the distance between the two given points. (-6, -5) and (2, 0)
Answer:
The answer is
[tex] \sqrt{41} \: \: or \: \: \: 6.403 \: \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-6, -5) and (2, 0)
The distance is
[tex]d = \sqrt{ ({ - 6 - 2})^{2} + ({ - 5 - 0})^{2} } \\ = \sqrt{ ({ - 4})^{2} + ({ - 5})^{2} } \\ = \sqrt{16 + 25} \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]
We have the final answer as
[tex] \sqrt{41} \: \: or \: \: \: 6.403 \: \: \: units[/tex]
Hope this helps you
Help me pleaseee I don’t understand
I'll solve one from each kind
Q1)
6 = a/4 + 2 (mutiply both sides)
24 = a + 8 (move the terms)
-a = 8 - 24 (calculate)
-a = 8 - 16 (change the signs)
a = 16
Q8)
2( 2 + 5) = -2 (divide both sides)
n + 5 = -1 (move the constant to the right)
n = -1 - 5 (calculate)
n= -6
Q3)
9x - 7 = 7 (cancel equal terms)
9x = 0 (divide both sides)
x = 0

Identify the equation modeled below, and then find its solution.
Zane is washing cars to help pay for a school trip. He gets paid $8 for every car he washes and made a total of $64 on Saturday. Write an equation to show how many cars Zane washed on Saturday.
8 − x = 64
64x = 8
8 + x = 64
8x = 64
Answer:
I just to the test
It D: 8x=64
Answer:
D: 8x = 64
Step-by-step explanation:
($8) equals the amount he makes for washing 1 car
($64) is the total amount Zane has made from washing cars
(X) is equal to how many cars he has washed for the total to be $64
Now, all we have to do is write down an equation that shows how we can find how many cars have been washed for him to get his sum of $64.
8 times x (x is equal to the number of cars he's washed) so 8 times something (or x) gives you the amount of money Zane has made which would be the only viable answer to the question.
8 - x = 64 - Incorrect
You would not be subtracting the amount of cars Zane has washed by the amount of money he is making per car.
64x = 8 - incorrect
This would mean you're multiplying the total amount of money Zane has made, by how many cars he's washed, which then equals the amount he makes per car. Doesn't make sense ik.
8 + x = 64 - incorrect
While this could look like a viable answer to what they're asking, don't be tricked. You have to multiply the number of cars Zane has washed by the amount he makes per car, otherwise you would just be adding 8 plus the number of cars he washed which does not equal $64.
Hope this helped:)
