What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total amount of money in Mary's account be = $ 120
The amount of money that gets deducted for each week = $ 5
Total number of weeks elapsed = 15 weeks
So , the equation will be
Total amount deducted after 15 weeks = number of weeks elapsed x amount of money that gets deducted for each week
Total amount deducted after 15 weeks = 15 x 5
= $ 75
Therefore , the equation will be
The amount left in Mary's account = total amount of money in Mary's account - Total amount deducted after 15 weeks
The amount left in Mary's account = 120 - 75
= $ 45
Hence , The amount of money Mary has left in her account is $ 45

Rayna and Maya are playing the integer card game. The cards in Rayna's hand are shown below: What is the total score of Rayna's hand? Support your answer by showing your work.
Answer:
The total score of Rayna's hand is described below in details.
Step-by-step explanation:
Start at 0. Combining a positive integer is a simplistic addition. Add 3 to get 3.
Combining a negative integer is like deducting : 3 + (-5) = 3 - 5 = -2.
Add 9, using 9 steps ahead, on the number line, to get 7.
Add -6, by deducting 6, to get 1.
Rayna's total composition is 1.
As for part 2, Rayna obtaining two more cards, which doesn't change his final record ...
Unless he got 2 zeroes, or he got pair cards with different symbols but similar magnitudes, such as 1 and -1.
The sign of a number is whether it is negative or positive. The magnitude (total value) of a number is how far that amount is from zero. The magnitude of a product is never negative.
The 2 cards do not change Rayna's point total, because their influences eliminate each other out. For instance, a 1 would move him one move ahead, on the number line, and a -1 would produce him one move behind, on the number line.

A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 4ft and a radius of 6ft. The tank will be made from metal (including its top and bottom). Suppose the total cost of the metal will be $14,318.40. How much will the metal cost per square foot? Use 3.14 for pi, and do not round your answer.
First find surface area.
I will skip the exact explanation and just go to it because well its the same concept as the prism.
π*6^2*2+6*2π*4
=72π+48π
=120π
Now we need to take 3.14 for pi getting about
120*3.14=376.8 square foot.
Now the total is 14318.4 dollars, so what's left is simple division.
14318.4/376.8=38
The metal cost 38 dollars per square feet :P

Please help me with this surds question. Explain how you got your answer.
Answer:
1/5
Step-by-step explanation:
b and c = [tex]\sqrt{50}[/tex] because 10 x 5 = 50
therefore the fraction is √2/ √50
to simplify you need to simplify the √50 into a number of √2 as the top is √2
√50 = √25 x √2
= 5√2
√2/5√2 = 1/5 if you divide both top and bottom by √2
Convert the following equation to slope-intercept form:
5x - 15y = 105
Answer:
D
Step-by-step explanation:
You need to solve the equation so that it looks like y = mb + b
So -15y = -5x + 105, then divide both sides by -15 so y = -5/-15 x + 105/-15
y = [tex]\frac{1}{3}[/tex] x - 7
If x2 + y2=6 , xy = 5 , then (X + y)2?

(x + y)² =16
Find and simplify an expression for the area of two rows of b squares with side lengths of b centimeters .
Answer:
2b³ cm²
Step-by-step explanation:
The Area of each square :
Area of a square = a² ; where a = side length
The side length = b
Hence, Area, A = b² = b² cm²
The total number of squares:
Number of rows * number of squares per row
2 * b = 2b
Therefore, total area :
Total number of squares * area of each square
(2b) * b²
= 2b³ cm²

Please help! Also please don’t comment just for points it’s not funny and I need this so I can raise my score back up.
Answer:
x = 8 and x = -3.
Step-by-step explanation:
-x^2 + 5x + 24 = 0 at the x intercepts.
Divide thru by -1:
x^2 - 5x - 24 = 0
(x - 8)(x + 3) = 0
x - 8 = 0 , x + 3 = 0
x = 8 and x = -3.

Answer: 1.567 × 10⁹
Step-by-step explanation:
1.6 × 10⁹ = 1.6 × 1000000000 = 1,600,000,000
3.3 × 10⁷ = 3.3 × 10000000 = 33,000,000
1,600,000,000 - 33,000,000 = 1,567,000,000
10⁹ = 1,000,000,000
1.567 × 1,000,000,000 = 1,567,000,000
Hope this helps!
