What is the value of b. If A+B=C and A=35 and C=25
Explain how you got this answer
Answer:
[tex]B=-10[/tex]
Step-by-step explanation:
Hi!
So let's write the equation again
[tex]A+B=C[/tex]
The next step is to plug in known values:
[tex]35+B=25[/tex]
Now we solve this as a normal algebra equation:
Do same to both sides
[tex]B = 25-35[/tex]
[tex]B=-10[/tex]
I hope this helped. Let me know if you have any questions

Simplify these exponents
1) 4^2
2) 6^2
3) 5^3
4) 2^6
Answer:
1.) 16
2.) 36
3.) 125
4.) 64
Step-by-step explanation:
multiply the base however many time it says so 4^2= 4*4=16 2^6=2*2*2*2*2*2=64
Answer:
Aight so...
1) 16
2) 36
3) 125
4) 64
Step-by-step explanation:
So when you have a number being squared or with an exponent of 2, all you're doing is multiplying it by itself. Same thing if it's being cubed, or it has an exponent of 3. You'll multiply it by itself 3 times. For example, 6^2 is 36 because 6 x 6 is 36. Hope this helps, I dunno if it did but I hope so ^^

GUYS, PLEASE ANSWER MY QUESTION! Please it's due today, everybody else got their questions answered! Listen to me!
Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.
Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct?
Answer:
Arianna is correct
Step-by-step explanation:
She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.
Candice's mother gave her $75.38 to go to the store. Candice bought
4 loaves of bread and 3 cartons of orange juice. Each loaf of bread cost
$2.45 and each carton of orange juice cost $4.55. How much money
does Candice have left?
Answer: Candice has $51.93 left after going to the store
Step-by-step explanation:
4 loaves of bread cost $9.80 and 3 cartons of orange juice cost $13.65. In total it cost $23.45. $75.38 - $23.45= $51.93
Answer:
Candace would have $51.93.
Step-by-step explanation:
The four loaves of bread would cost $9.80
The three cartons of juice would cost $13.65
Add these up and we get $23.45
Subtract this from $75.38, and we get the answer of $51.93

Gina visited the aquarium with some of her cousins, aunts, and uncles. The group bought 20 admission tickets for $340. Adult tickets cost $20, and children’s tickets cost $15. How many adult tickets and how many children tickets did the group buy?
Write a system of equations.
Answer:
Look at the attachment
Step-by-step explanation:
There are 12 children tickets did the group buy.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The group bought 20 admission tickets for $340.
And, Adult tickets cost $20, and children’s tickets cost $15.
Let number of children = x
And, Number of adult = y
Hence, We get;
The system of equations are,
x + y = 20
y = 20 - x .. (i)
And, 15x + 20y = 340
3x + 4y = 68 .. (ii)
Substitute the value of y from (i) in (ii);
3x + 4(20 - x) = 68
3x + 80 - 4x = 68
80 - 68 = x
x = 12
Thus, There are 12 children tickets did the group buy.

IF YOU R GOOD AT CALCULUS PLZ HELP AND IF U STEAL POINTS YOU GET REPORTED
If an object is dropped from a height of 55 feet, the function d=-16t^2+55 gives the height of the object after t seconds. Graph this function. Approximately how long does it take the object to reach the ground (d= 0)?
Answer:
To find the time to reach ground solve - 16t^2 + 55 = 0
t^2 = 55/16
t = sqrt55 / 4 = 1.85 seconds

Answer:
1152 ft^2
Step-by-step explanation:
There are 7 faces on this solid.
I will label the faces and will calculate each area with an explanation.
Faces 1 and 2:
The front face and the back face are congruent and have 5 sides each. Each face is a rectangle with a triangle above it. The lower rectangular part has dimensions 9 ft by 12 ft. The triangle above the rectangle has base 9 ft and height 16 ft - 12 ft = 4 ft.
Each face is a rectangle and a triangle.
area = area of rectangle + area of triangle
area = LW + bh/2
area = 9 ft * 12 ft + 9 ft * 4 ft/2 = 108 ft^2 + 18 ft^2 = 126 ft^2
This is area of of face 1, the front face. Face 2, the rear face has the same area.
A1 = 126 ft^2
A2 = 126 ft^2
Face 3: The bottom of the solid is a rectangle measuring 9 ft by 20 ft
area = LW
area = 9 ft * 20 ft = 180 ft^2
A3 = 180 ft^2
Faces 4 and 5:
The left vertical face and the right vertical face are congruent rectangles measuring 12 ft by 20 ft.
area = LW
area = 12 ft * 20 ft = 240 ft^2
A4 = 240 ft^2
A5 = 240 ft^2
Faces 6 and 7 are the top right and left inclined rectangles. They are congruent, and each one has dimensions 6 ft by 20 ft.
area = LW
area = 6 ft * 20 ft = 120 ft^2
We need 2 of these area.
A6 = 120 ft^2
A7 = 120 ft^2
total surface area = A1 + A2 + A3 + A4 + A5 + A6 + A7
total surface area = 126 ft^2 + 126 ft^2 + 180 ft^2 + 240 ft^2 + 240 ft^2 + 120 ft^2 + 120 ft^2
total surface area = 1152 ft^2
Solve for y.
6y-1.5x=8
Answer: Y = 0.25x + 4/3
Step-by-step explanation:
Step 1: Add 1.5 to both sides
-1.5x + 6 + 1.5x = 8 + 1.5x
6y = 1.5x + 8
Step 2: Divide both sides by 6
6y/6 = 1.5x + 8/6
Y = 0.25x + 4/3
