What is an equation that can be used to find x, the temperature before the gº increase
Drag the number, symbol, or operation sign to each box to complete the equation or symbol to
Answer:
37-9=28
Step-by-step explanation:
it was 28 F then rose 9 which is 37 so 37-9 =28
The equation is 37 - 9= x.
What is 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. LHS = RHS is a common mathematical formula.
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:
After the temperature rose 9°F, the thermometer read 37°F.
let x be the temperature before the 9º increase.
So, 37 - 9= x
x= 28°F.
Hence, the equation is 37 - 9= x.

A, the current needed to operate
the electric fan
Answer: 73.33A
Step-by-step explanation:
Resistance (R)= 3.0 kN
Voltage (V)= 220 volts
Current (I)= Unknown
The formula to calculate the current will be:
Current = Voltage / Resistance
Current = 220 / 3.0
Current = 73.33 A
Therefore, the current needed to operate the electric fan is 73.33.

You have put ₹ 2500 in your bank account. After some years, you observe that you have received interest and the amount now is ₹ 4100. What is the percentage of increase?
Answer:
64%
Step-by-step explanation:
The first step is to calculate the increase
= 4100-2500
= 1600
Therefore the percentage increase can be calculated as follows
= increase/original number × 100
= 1600/2500 × 100
= 0.64 × 100
= 64%
Hence the percentage increase is 64%

What is the inverse of the function f(x) = 2x + 1?
Answer:
y = x/2 -1/2
Step-by-step explanation:
let’s write this equation as
y = 2x + 1
to find the inverse let’s switch x and y
x = 2y + 1
and solve for y
x -1 = 2y
y = x/2 -1/2
so the inverse is
y = x/2 -1/2

Give your answer in simplest form.
Answer:
I think it is -1
Step-by-step explanation:
Simplify the problem first.
Let's start with the numerator.
FYI, this, ^, means raised to the power of.
4^3 = 64
-12 + 2^2 = -12 +4 which equals -8
64/-8 = -8
Now simplify the denominator.
(2*3)^2 = 6^2 which equals 36.
-5*2*3 = -10*3 which equals -30
Then add the 2 to the end.
36 + (-30) + 2 = 6 + 2 which equals 8. This is the denominator.
Your fraction now is:
-8/8
Simplify this and you will get -1 as the simplest form.

Which equation is parallel to CD which passes through through points C (-3,4) and D (7,-2)?
Answer:
y = - [tex]\frac{3}{5}[/tex] x + 1
Step-by-step explanation:
Parallel lines have equal slopes
Calculate m of CD using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = C(- 3, 4) and (x₂, y₂ ) = D(7, - 2)
m = [tex]\frac{-2-4}{7+3}[/tex] = [tex]\frac{-6}{10}[/tex] = - [tex]\frac{3}{5}[/tex] , thus
y = - [tex]\frac{3}{5}[/tex] x + 1 ← is parallel to CD

Melinda and Paula shovel driveways and sidewalks in the winter as a way to earn extra money. Together they shoveled 450 square feet of sidewalk in 30 minutes. Then Melinda shoveled for 20 minutes while Paula shoveled for 25 minutes to complete 345 square feet of driveway. 30x + 30y = 450 20x + 25y = 345 How much more can Paula shovel in 1 minute than Melinda? 3 square feet per minute 6 square feet per minute 9 square feet per minute 15 square feet per minute
Answer: A: 3 square feet per minute
Step-by-step explanation:
The square feet more that Paula can shovel in 1 minute more than Melinda is 3 square feet per minute.
System of equations
30x + + 30y = 450 equation 1
20x + 25y = 345 equation 2
Where:
x = square feet shovelled by Melinda
y = square feet shovelled by Paula
What is the square feet shovelled by Paula?The first step is to multiply equation 1 by 20 and equation 2 by 30
600x + 600y = 9000 equation 3
600x + 750 y = 10,350 equation 4
Subtract equation 3 from equation 4
150y = 1350
Divide both sides by 150
y = 9 square meters
What is the square feet shovelled by Melinda?Substitute for y in equation 1
30x + 30(9) = 450
30x + 270 = 450
30x = 450 - 270
30x = 180
x = 6 square meters
How much more can Paula shovel in 1 minute than Melinda?9 - 6 = 3 square meters
