what is 4.5(x - 9)= -13.5
Answer:
6
Step-by-step explanation:
4.5(x-9)=-13.5
((distribute the 4.5 to the x (4.5x) and distribute the 4.5 to the -9 (-40.5)))
4.5x-40.5=-13.5
4.5x=27
x=27/4.5
x=6
hello, last question about this assignment. please answer asap if you can and show work. thanks
Answer:
52 in^2
Step-by-step explanation:
If the diameter = 3 in, then the radius = 1.5 in.
To find the surface area, you need to find the area of the two circle areas (the base and the top of the cylinder) and the "sides" of the cylinder. If you look at the net shape of a cylinder, look at the picture below. That middle region aka the "side" of the cylinder is actually a rectangle. The length of the rectangle is also the circumference of the circle and the width is also the height of the can.
So:
2 * Area of the circle + rectangle = total surface area of the can
= 2(πr^2) + 2πrh
= 2π(1.5^2) + 2π(1.5)(4)
= 2π(2.25) + 12π
= 4.5π + 12π
= 16.5π
≈ 51.8
≈ 52 in^2

b^2-4b+3=0
2n^2 + 7 = -4n + 5
x - 3x^2 = 5+ 2x - x^2
Answer:
Step-by-step explanation:
Answer:
b^2-4b+3=0
b²-3x-b+3=0
b(b-3)-1(b-3)=0
(b-3)(b-1)=0
either
b=3 or b=1
.
2n^2 + 7 = -4n + 5
2n²+4n+7-5=0
2n²+4n+2=0
2(n²+2n+1)=0
(n+1)²=0/2
:.n=-1
.
x - 3x^2 = 5+ 2x - x^2
0=5+ 2x - x^2-x +3x^2
0=5+x+2x²
2x²+x+5=0
comparing above equation with ax²+bx +c we get
a=2
b=1
c=5
x={-b±√(b²-4ac)}/2a ={-1±√(1²-4×2×5)}/2×1
={-1±√-39}/2

A 30 gallon tank is being filled at a rate of 2 gallons per minute. There was 6 gallons of water in the tank to begin. Let y represent the total amount of water in the tank and m represent the number of minutes. Write an equation to model the amount of water in the tank.
The amount of water in the tank represented by the equation as:
y = 2m + 6, where y is the total amount of water in the tank, m is the number of minutes.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
Let y represent the total amount of water in the tank and m represent the number of minutes.
We can model the amount of water in the tank using the equation:
y = 2m + 6
This equation states that the total amount of water in the tank (y) is equal to the rate of filling (2 gallons per minute) multiplied by the number of minutes (m), plus the initial amount of water in the tank (6 gallons).
For example, if we let m = 5, then y = 2 × 5 + 6 = 16, which means that after 5 minutes, the tank will contain 16 gallons of water.

Terrell has $2,700 in his checking account and $1500 in his savings account. He
uses his checking account to pay bills, which are $240 each month.
a) In how many months will his checking account balance equal his savings account
balance?
b) If Terrell deposited an additional $720 in his savings account, in how many
months will his balances be the same?
Answer:
1.8 month and they wouldnt
Step-by-step explanation:
brainalist
The number of months when both accounts have the same balance is 5 months. If $720 is deposited each month in the saving account, then the number of months when both accounts have the same balance is 1.25 months.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Terrell has $2,700 in his financial records and $1500 in his bank account. He utilizes his financial records to take care of bills, which are $240 every month.
Let 'x' be the number of months. Then the equation is given as,
1500 = 2700 - 240 x
240 x = 1200
x = 5 months
Assuming Terrell kept an extra $720 in his bank account. Then the equation is given as,
1500 + 720 x = 2700 - 240 x
960x = 1200
x = 1.25 months
The quantity of months when the two records have a similar equilibrium is 5 months. On the off chance that $720 is kept every month in the saving record, the number of months when the two records have a similar equilibrium is 1.25 months.

Answer:
The correct answer to a is 3 1/2 same answer for the other answer.
Answer:
a. 7/2 OR 3 1/2 Either answer should be acceptable
b. 82/15 OR 5 7/15 Either answer should be acceptable
Step-by-step explanation:
a. 5 3/4 = so first multiply the denominator, 4, by the whole number 5 so 4 x 5 is equal to 20. Add this to your numerator, 3.
20 + 3 = 23 so the new fraction is 23/4
Same thing with 2 1/4 4 x 2 = 8 + 1 = 9 9/4
23/4 - 9/4 = 14/4 simplify this to 7/2
b. Same process here:
7 2/3 3 x 7 = 21 + 2 = 23 23/3
2 1/5 5 x 2 = 10 + 1 = 11 11/5
This time, we need a common denominator
3 x 5 = 15
5 x 3 = 15
23/3 x 5/5 = 115/15
11/5 x 3 = 33/15
115/15 - 33/15 = 82/15
