Solve the equation 3 x+5 y=16 for y

Mathematics
1 answer:
Liono4ka [1.6K]3 years ago
8 0

Answer:

Y = (16 - 3x)/5

Step-by-step explanation:

3x + 5y = 16

subtract 3x from both sides:

16-3x = 5y

divide both sides by 5:

(16 - 3x) / 5 = y

GenaCL600 [577]

\sf\large\underline{\star Given:-}

\rightarrow Length of rectangular prism = \sf\red{4m}

\rightarrow Width of rectangular prism = \sf\red{7m}

\rightarrow Height of rectangular prism = \sf\red{8.5m}

\sf\large\underline{\star To \: Find:-}

  • Volume of given Rectangular Prism.

\sf\large\underline{\star Solution:-}

\rightarrow We can find the volume of given rectangular prism by using the formula:

\sf\blue{Length × Width ×Height}

So, let's begin:

\rightarrow Volume of rectangular prism = \sf{Length × Width ×Height}(putting the value of length, width and height from the above given)

\rightarrow\sf{=\:4× 7 ×8.5}

\rightarrow\sf{=\:28×8.5}

\rightarrow\sf{=\:238m^3}

Therefore, volume of the given rectangular prism = \sf\purple{238m^3.}

Lorena calculated the slope of the linear function that is represented by the table of values as shown. x y –10 15 –8 27 –6 39 –
Anvisha [2.4K]

She made a mistake when she subtracted x1 from x2.

Step-by-step explanation:

Step 1 :

a)

The formula used by Lorena to calculate the slope between 2 points is correct

So the statement given in option 1 is not the reason for her mistake

Step 2:

b)

She has taken the fourth and fifth point and correctly used the x and y co ordinates to calculate the slope

Hence the statement in second option is not true

Step 3:

c)

While calculating the slope the denominator is -2 - (-4) . This gives 2 as the answer. But she has made a mistake in this subtraction giving -6 as the answer.

Hence she has made a mistake in subtracting x1 from x2 and this statement is true

Step 4:

d)

She has not made any mistake in subtracting y1 from y2. Hence this statement is not true
