Suppose  x is the total cost for the first purchase, cost of the bread = b and cost of the milk = m
Then:-
 y     =    5b + 2m
y - 4.2 = 2b + 5m
Subtract:-
4.2 = 3b - 3m
b - m = 4.2 / 3 = 1.4

That is bread costs $1.40 more than the milk.   (Answer).  Its A

The equation represents an ellipse. which points are the vertices of the ellipse? (7, 1) and (7, −5) (7, −10) and (7, 6) (10, −2
OleMash [197]

The points which represents the vertices of the given equation are; (15, −2) and (−1, −2).

<h3>Which points among the answer choices represents the vertices of the ellipse whose equation is given?</h3>

The complete question gives the equation of the ellipse as; (x-7)²/64+(y+2)²/9=1.

Since, It follows from convention that general equation of ellipse with centre as (h, k) takes the form;

(x-h)²/a² +(y-k)²/b² = 1.

Consequently, it follows from observation that the value of a and b in the given equation in the task content is; √64 = 8 and √9 = 3 respectively.

Since, 8 > 3, The vertices of the ellipse are given by; (h±a, k).

The vertices in this scenario are therefore;

(7+8, -2) and (7-8, -2).

= (15, -2) and (-1, -2).

What is the value of x? <br> (x + 40)° (3x)°<br><br> A. 20<br> B.35 <br> C. 60<br> D. 70
Olenka [21]
Hello!

We are given the equation below.

x+40=3x

We want to get all of the variables on side. First of all let's subtract 40 from both sides.

x=3x-40

Now we rearrange our equation so the commutative property will work.

x=3x+(-40)
x=-40+3x

Now we subtract 3x from both sides.

-2x=-40

We divide both sides by -2.

x=20

Our answer is A) 20.

I hope this helps!

Find the six first terms of an arithmetic sequence with:<br> d = 2<br> Po= 30
alexgriva [62]

Answer:

The first six terms of this arithmetic sequence are: 30, 32, 34, 36, 38, 40

Step-by-step explanation:

The nth term of an arithmetic sequence is given by:

P_n = P_0 + nd

In which d is the common difference, that is, each term is increased by d.

d = 2, Po= 30

First term is 30, each consecutive is increased by 2. So

30, 32, 34, 36, 38, 40

Find the slope of the line:<br> 5x+3y=6
natka813 [3]
To get the result we have to transform given formula into y=ax+b form.
Lets do this
5x+3y=6   /-5x  (subtract 5x both sides)
3y=-5x+6  /:3  (divide both sides by 3)
y=-\frac{5}{3} x+6
In form y=ax+b we know that a is slope and b is y intersect. We can read from our transformed equation that slope a=-\frac{5}{3}and its the result

To order numbers, they need to all be under the form. So let's transform all this numbers to the decimal form.

3/5 = 0.6
-24% = -24/100 = -0.24
√9 = 3 = 3.0 (all integers are decimals with a zero after the decimal point)
-2 = -2.0
1.6 bar = 1.66666666666 (the bar above the 6 represents an endless number of the digit 6)
π² =  9.86........ endless
(4√5)/2 = 4.47...... endless
4(4/5) = 4 + 4/5 = 4 + 0.8 = 4.8

Now that we got all forms under the decimal form, we can order the numbers from least to greatest:

-2.0 < -0.24 < 0.6 < 1.6666 < 4.47 < 4.8 < 9.86 < 3.0
By correspondence, we get:

-2 < -24% < 3/5 < 1.6 bar < (4√5)/2 < 4(4/5) < π² < 3

Hope this helps! :D
