Answers

Answer 1

Answer:

change the expression to y

Step-by-step explanation:

[tex]x + 3y = 9[/tex]

[tex]3y = - x + 9[/tex]

[tex]y = \frac{ - 1}{3} x + \frac{9}{3} [/tex]

the gradient is the coefficient of x,

[tex] - \frac{1}{3} [/tex]

Asif would pay $2400 for a jacket if the price was reduced by 40% what is the the original price of the jacket

Answers

Answer:  $4,000

Step-by-step explanation:

If the price of the jacket is reduced by 40%, it ends up being $2,400.

Assuming the original price is x, the expression will be:

x - (40% * x) = 2,400

x - 0.4x = 2,400

0.6x = 2,400

x = 2,400 / 0.6

x = $4,000

if a:3=b:4 then 4a-3b+5=??

Answers

Answer:

4a - 3b + 5 = 5

Step-by-step explanation:

Express the ratios in fractional form

[tex]\frac{a}{3}[/tex] = [tex]\frac{b}{4}[/tex] ( cross- multiply )

4a = 3b ( subtract 3b from both sides )

4a - 3b = 0

Then

4a - 3b + 5 = 0 + 5 = 5

3n + 8 = 53
I don’t understand how to find the n

Answers

Answer:

n=15

Step-by-step explanation:

subtract 8 from both sides to get 3n=45

divide both sides by 3 to solve for n to get n=15

Answer:

n = 15

Step-by-step explanation:

3n + 8 = 53

the first step we are going to do is combine the like terms by moving the constant (8) to the right and subtracting

3n = 45

next step, we are going to isolate the n by dividing by 3 on both sides of the equation

3n divided by 3 is just n and 45 divided by 3 is 15, so we have our answer

Evaluate the expression, 7x+8(x-3). Assume that x=4.

The bases of a cylinder have a diameter of 4 inches. The height of the cylinder is 6 inches. What is the total surface area of the cylinder?

Answers

Answer:

Step-by-step explanation:

area of base = π4² = 16π in²

lateral area = 2πrh = 2π·4·6 = 48π in²

surface area = 2×16π + 48π = 80π in² ≅ 251.3 in²

Answer: 100.54 in^2

Step-by-step explanation:

(the area of a circle*2) + (the circumference*the height) = the surface area of the circle

Area of a circle: Pi*r^2

Circumference: 2*Pi*r

Answer:

the snake grows 0.38m

Step-by-step explanation:

To find out how much the snake grows you need to find the differences between the length of the snake after and the length before, this means you do:

the grow = the length of the snake after - the length of the snake before

= [tex]1\frac{1}{4}[/tex] - 0.87

= 1.25 - 0.87

= 0.38m

so the snake grows 0.38m
