Answer 1

Answer:

7

Step-by-step explanation:

BW is 1/3 of the way of JB

like the other question we set up an equation

2x+1=10x+1 but because BW is only one third of the way we have to multiply its side by 3 and the new equation is

9x+3=10x+1

step 1: subtract each side by 9x

3=x+1

step 2; subtract each side by 1

2=x

Next we plug in 2 to x in 3x+1 and get a final answer of

BW = 7

you can drive 180 miles on 1/2 of a tank of gas in 3 hours,how far can u drive on one tank of gas?​

Answers

360 miles

explanation :

1 tank is 2 times as much as half a tank

so u double the half tank for a whole tank

then you double the miles you can drive on a half tank to find the number of miles you can drive on a full tank

so

1/2(2)= 180(2)

2 = 360

Answer:

2x+y < 7

Step-by-step explanation:

We  are below the line which means less than ( since the line is dotted)

We need to determine the equation for the line

The y intercept is 7 and the slope is

( 0,7) and (2,3)

m = ( 3-7)/( 2-0) = -4/2 = -2

In slope intercept form ( y=mx+b)

y = -2x+7

Changing this to an inequality

y < -2x+7

Add 2x to each side

2x+y < 7

Seven men have seven wives each man and wife have seven children what are the number of people?

This makes it 7 Men + 7Wives + 7 Children = 21 People  

Therefore

here total people is 7 Men have 7 Wives Riddle is 21 People

[tex](-3x^2y)^{4}[/tex]


PLEASE EXPLAIN HOW YOU GOT YOUR ANSWER

Answers

Answer:

errr polynomials ahaha

so basically we can multiply the power outside of the parantheses with the exponents on the inside:

so

[tex]-3x^{2*4} y^{1*4}[/tex]

this will give us:

-3x^8y^4

we also unfortunately, have to use the power on the coefficient -3 as well  and we cant just MULTIPLY -3 by 4, we are going to have to multiply -3 with -3 4 TIMES(anytime we see a coefficient we MUST multiply the coefficient by itself according to the number outside of the parantheses)

so:

-3*-3*-3*-3=81

final expression

[tex]81x^{8}y^{4}[/tex]

When you have an power outside of a bracket, you have to multiply all the powers inside by the one outside...

So you would get x^2 x ^4 which is x^8

And y x ^4 which would be y^4

Therefore the answer will be -3x^8y^4

Hope this helps! Any questions let me know :)

Write an equation in slope-intercept form of the line that passes through the points (2, 4) and (3,6).

Answers

Answer:

[tex]y=2x[/tex]

Step-by-step explanation:

We want to write an equation in slope-intercept form that passes through the points (2, 4) and (3, 6).

So, we will first find the slope. Let (2, 4) be (x₁, y₁) an let (3, 6) be (x₂, y₂).

The slope formula is given by:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

So, by substitution, our slope is:

[tex]\displaystyle m=\frac{6-4}{3-2}=\frac{2}{1}=2[/tex]

Now, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

By substitution:

[tex]y-(4)=2(x-(2))[/tex]

Distribute:

[tex]y-4=2x-4[/tex]

Adding 4 to both sides yields:

[tex]y=2x[/tex]

And we have our equation.

In this case, the y-intercept is 0.

Jill's weight is 92 kg 250 g. Jill's sister's weight is 8 kg 600 g less than Jill's weight. How much does the sister weigh?

Answers

Answer:

S = 83 g and 650 kg.

Step-by-step explanation:

Gram (g)= 1000 kilograms (kg).

Jill (J)= 92000 + 250 kg.

J = 92250 kg

Sister (S) = J - (8000 + 600 kg)

S = 92250 - 8600 kg

S = 83650 kg.

S = 83 g and 650 kg.

I really need help for this geometry question, I would appreciate any help thank you.

Answers

you know that you have the Opposite side and the Adjacent side. therefore you would use Tangent (T= O/A)
because you are finding the angle you would go Tan^-1(12÷20) =31°
it is 12÷20 because O/A and the 12 is the opposite side therefore It would be O and 20 is the adjacent side therefore equaling 20 so O/A = 12/20
Your answer is 31°

Four typists can type a total of 600 memos in three days. At that rate, how many memos can three typists type in one day?

Answers

150 memos for 3 typists

The number of memos three typists can type in one day is given by the equation A = 150 memos

What is an 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.

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 data ,

Let the number of memos three typists can type in one day be A

Now , the equation will be

The number of typists = 4

The total number of memos by 4 typists = 600 words in 3 days

So , the number of memos by one typist for 3 days = total number of memos by 4 typists / 4

Substituting the values in the equation , we get

The number of memos by one typist for 3 days = 600/4

The number of memos by one typist for 3 days = 150 memos

So ,

The number of memos by one typist for 1 day = number of memos by one typist for 3 days / 3

Substituting the values in the equation , we get

The number of memos by one typist for 1 day = 150/3

The number of memos by one typist for 1 day = 50 memos

So ,

Number of memos three typists can type in one day A = number of memos by one typist for 1 day x 3

Substituting the values in the equation , we get

Number of memos three typists can type in one day A = 50 x 3

Number of memos three typists can type in one day A = 150 memos

Therefore , the value of A is 150 memos

Hence , the number of memos is 150 memos

answer for 1a: 0.40, which is 40 cents.

what you need to do is you need to divide the amount of money of the drink which is £3.20, by the quantity of the drink which is 8, since £3.20 is the total amount of money for 8 cans.
£3.20 divided by 8 is 0.4, which logically would mean in your question it calculates to 40 cents.
another proof that the answer is 40 cents is when you multiply 0.40 by 8, it calculates to 3.2, which would mean in your question it calculates to £3.20 in total.
the answer to 1a is 40 cents.


answer for 1b: 0.35, which is 35 cents.
same thing as the first question, you need to divide the total amount of money of the drink which is £5.25, by the quantity of the drink which is 15, to calculate the actual price of the drink.
5.25 divided by 15 calculates to 0.35.
as said, the proof that the answer is right is if you multiply 0.35 by 15, it will calculate to 5.25.
the answer to 1b is 35 cents.

answer for 1c: the best value is shop A, because we have worked out that shop A sells the drink for 40 cents, and shop B sells the drink for 35 cents. therefore, shop A gets 5c more profit than shop B.
