W = 3x + 7y solve for y

Answers

Answer 1

Answer:

The value of the equation [tex]y=\frac{W-3x}{7}[/tex].

Step-by-step explanation:

Consider the provided equation.

[tex]W = 3x + 7y[/tex]

We need to solve the provided equation for y.

Subtract 3x from both side.

[tex]W-3x= 3x-3x+ 7y[/tex]

[tex]W-3x=7y[/tex]

Divide both sides by 7.

[tex]\frac{7y}{7}=\frac{W-3x}{7}[/tex]

[tex]y=\frac{W-3x}{7}[/tex]

Hence, the value of the equation is [tex]y=\frac{W-3x}{7}[/tex].

Answer 2

To solve the equation W = 3x + 7y for y, subtract 3x from both sides and then divide by 7 to isolate y, resulting in the solution y = (W - 3x) / 7.

To solve for y in the equation W = 3x + 7y, we need to isolate y. First, we subtract 3x from both sides of the equation so that the terms with y are on one side:

W - 3x = 3x + 7y - 3x

This simplifies to:

W - 3x = 7y

Next, we divide both sides of the equation by 7 to solve for y:

(W - 3x) / 7 = y

Therefore, the solution for y in terms of W and x is y = (W - 3x) / 7.

16 - 2t = 5t + 9

What number does t represent? I'm bored

Answers

Try not to be bored.  You can take the attitude that you actually like math, and that you will some day actually be a MathGenius.

t represents an unknown quantity defined by the equation 16 - 2t = 5t + 9.

To find this value, do the following:  Add 2t to both sides, and then subtract 9 from both sides.  You'll end up with 7t = 7, which yields t = 1.

We call this the "solution" of the equation given.

Answer:

The correct option is B) [tex]10m^{7}+8m^{5}-2m^{4}[/tex]

Step-by-step explanation:

we need to multiply the given expression

Given [tex]2m^{4}(5m^{3}+4m-1)[/tex]

Multiply polynomial term wise,

[tex](2m^{4}\times 5m^{3})+(2m^{4}\times 4m)-2m^{4}[/tex]

[tex]10m^{4+3}+8m^{4+1}-2m^{4}[/tex]

[tex]10m^{7}+8m^{5}-2m^{4}[/tex]

Therefore, the correct option is B) [tex]10m^{7}+8m^{5}-2m^{4}[/tex]

Find the side length of a square with the given area. 121in(2 Exponent)

A.) 11 Inches.
B.) 60.5 Inches.
C.) 1,331 Inches.
D.) 14,641 Inches.

Answers

Answer:

A.) 11 inches

Step-by-step explanation:

There's a couple of ways to do this. If you know how to take a square root, use this way: [tex]\sqrt{121}[/tex] is equal to [tex]\sqrt{11*11}[/tex]. So that would mean that [tex]\sqrt{121} = \sqrt{11^{2} }[/tex]. Canceling it out (the square root of a square equals the original base), it equals 11. So the side length would be 11 inches.

Remember, we know the AREA and need to find the side length, so this is why we don't square 121 to get 14,641. 121 is the area and not the side length.

Hope this helps.

Deshawn fuels 2 yachts and 6 barges. Each boat gets 126 gallons of fuel. To find how much fuel he needs for all the boats, deshawn first findsthe number of boats, then he uses an algorithm to multiply. Which are the three partial products deshawn could add to find the final product?

Answers

Since there are 8 boats (2 yachts + 6 barges) the three partial products would be as follows:
100 * 8
20 * 8
6 * 8
These are from taking the gallons of fuel for each boat that are needed and breaking it into the place values. 
(100*8) + (20* 8) + (6*8) =
800+160+48=
1008 gallons of fuel are needed. 
Final answer:

Deshawn, who fuels 2 yachts and 6 barges each with 126 gallons of fuel, can find the total fuel needed by calculating and summing three partial products; 800, 160 and 48, derived from breaking down the multiplication of 8 (total boats) and 126 (gallons per boat). The combined total is 1008 gallons.

Explanation:

Deshawn needs to fuel 2 yachts and 6 barges, making a total of 8 boats. Each boat requires 126 gallons of fuel. Deshawn's algorithm for determining the total fuel required involves finding three partial products to multiply.

If we break down the multiplication of 8 (total boats) and 126 (gallons per boat), into three parts we get:

Multiplying 8 by 100 to get 800. Multiplying 8 by 20 (part of the 26 in 126) to get 160. Finally, multiplying 8 by 6 (the units digit in 126) to get 48.

These are the three partial products that Deshawn could add together (800 + 160 +48) to find the total fuel needed which is 1008 gallons.

Coupon A: $18 rebate on a $59 printer
Coupon B: 35% off of a $59 printer

With coupon A, the final price is 59-18 = 41 dollars

So coupon B offers the lower price. The price difference between the coupon options is $2.65 (41-38.35 = 2.65); meaning that coupon B is the better option by $2.65

Final answer:

To find the fraction of people in the class who are either over 65 or under 40, we add the fractions of people in each age group. The maximum fraction is 1.

Explanation:

To find the fraction of people in the class who are either over 65 or under 40, we need to add the fractions of people in each age group. First, we find the fraction of people over 65 by multiplying the total fraction by the fraction of people over 65: 5/8 * 1 = 5/8. Next, we find the fraction of people under 40 by multiplying the total fraction by the fraction of people under 40: 1/4 * 1 = 1/4. Finally, we add the two fractions together to find the total fraction of people who are either over 65 or under 40: 5/8 + 1/4 = 9/8. However, fractions cannot be greater than 1, so the maximum fraction is 1. Therefore, the fraction of people in the class who are either over 65 or under 40 is 1.

Which number is a solution of the inequality 7x-5>-2? ( by the way that sign is supposed to be a less than or equal to)
A.-3
B.-1
C.0
D.1

Answers

Final answer:

The correct answer to the inequality 7x - 5 ≥ -2 is D. 1, since 1 is greater than 3/7 and thus satisfies the inequality.

Explanation:

To solve the inequality 7x - 5 ≥ -2, we need to isolate x. Follow these steps:

Add 5 to both sides of the inequality to cancel out the -5 on the left: 7x ≥ 3.

Divide both sides by 7 to solve for x: x ≥ 3/7.

Now we need to determine which of the provided options is a solution to the inequality. We have:

A. -3 (which is less than 3/7)

B. -1 (which is also less than 3/7)

C. 0 (which is again, less than 3/7)

D. 1 (which is greater than 3/7, making it a solution to the inequality)

The correct answer is D. 1 because it satisfies the given inequality.
