If r+9=42 does r+9-9=42+9

i say its 280 miles because the point is at half of 320 and 240 and 320-240 is 80 and half of eithegy is 40 therefore 240+40 is 280

Answer:

Bonnie is correct

Step-by-step explanation: from the above question:

Susan and bonnie are shopping for school clothes.

Susan has $50 and a coupon for a $10 discount at a clothing store where each shirt cost $12.

Susan thinks that she can buy three shirts, but bonnie says Susan can by five shirts.

Hence:

Discount = $10, Discounted price always carries the minus(-) sign

The cost of 1 shirt = $12

Let the number of shirts she can buy = x

Hence our Equation =

$12 × x - $10 = $50

12x = $50 + 10

12x = $60

x = $60/12

x = 5 shirts

Therefore, Bonnie is correct because she can only buy 5 shirts

Answer:

k = 11b - 8 (easiest to understand)

extra:

k = -8 + 11b

or

11b = -8 - k

etc. ( anything mixing up the components of the equation ).

Answer:

x=1

Step-by-step explanation:

Answer:

x = 1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2.3x −3.2 + 1.6x = 0.7x

2.3x + − 3.2 + 1.6x = 0.7x

(2.3x + 1.6x) + (−3.2 )= 0.7x (Combine Like Terms)

3.9x + −3.2 = 0.7x

3.9x − 3.2 = 0.7x

Step 2: Subtract 0.7x from both sides.

3.9x − 3.2 − 0.7x = 0.7x − 0.7x

3.2x − 3.2 = 0

Step 3: Add 3.2 to both sides.

3.2x − 3.2 + 3.2 = 0 + 3.2

3.2x = 3.2

Step 4: Divide both sides by 3.2.

x = 1

Answer:

x = 3

Step-by-step explanation:

Since the quadrilateral QRST is a square, all sides are equal

Therefore QR must be equal to TS

3x - 6 = 6 - x

4x = 12

x = 3

If Neptune's distance from the sun is about 4.5 billion km and Venus distance is 2×[tex]10^{8}[/tex] km, then its 22.5 times farther is Neptune from the sun than Venus.

The Neptune's distance from sun = 4.5 billion km

we know

1 billion = [tex]10^{9}[/tex]

The Venus's distance from sun = 2×[tex]10^{8}[/tex] km

How many times farther is Neptune from the sun than Venus = The Neptune's distance from sun / The Venus's distance from sun

Substitute the values in the equation

= (4.5×[tex]10^{9}[/tex])÷(2×[tex]10^{8}[/tex])

= 22.5

Hence, If Neptune's distance from the sun is about 4.5 billion km and Venus distance is 2×[tex]10^{8}[/tex] km, then its 22.5 times farther is Neptune from the sun than Venus.

The possible value of the expression is 5 > y > 3

The expression is given as

1/5 < 1/y < 1/3

Take the exponent of the sides of the inequality

(The inequality sign would change)

So, we have

5 > y > 3

Hence, the possible value of the expression is 5 > y > 3

Step-by-step explanation:

The standard error of the estimate gives a measure of the variability around the regression line.

A regression line represents the relationship between an independent and a dependent variable in a statistical study. In this the standard error of the estimate represents the variation from the theoretical value which is on the regression line. So it gives the measure of the variability around the regression line. It is measured from the distance between the values on the regression line and the value of the estimate.

When the standard error is zero, the study is said to be perfect( which is rare in real cases). So a range of error of (0.8-0.9) is considered as acceptable. So to make the estimate precise, standard error should be the minimum.

Answer:

The answer is below

Step-by-step explanation:

An integer is a whole number which is either positive, negative or zero.

Given that:

P=(x | x is an integer divisible by 2}. An integer divisible by 2 can be represented by 2k, where k is an integer, hence:

P = (..., -6, -4, -2, 0, 2, 4, 6, ...)

Q= (x | x is an odd integer). An odd integer can be represented by 2k + 1, where k is an integer, hence:

Q = (..., -5, -3, -1, 1, 3, 5, 7, 9 ...)

R = (x | x is an integer divisible by 3). An integer divisible by 3 can be represented by 3k, where k is an integer, hence:

R = (..., -12, -9, -6, -3, 0, 3, 6, 9, ...)

From the above we can see that Q and P are disjoint set, that is P ∩ Q = 0

But P and R have common numbers (..., -6, 0, 6, 12,...) i.e. P ∩ R ≠ 0

Also Q and R have common numbers (..., -3, 3, 9,...) i.e. Q ∩ R ≠ 0

• if he has 30  vases, he would be able to put two tulips in each

• if he has 20 vases, he would be able to put three tulips in each  

• if he has 15 vases, he would be able to put four tulips in each

if he has 12 vases, he would be able to put 5 tulips in each

if he has 10 vases, he would be able to put 6 tulips in each

Step-by-step explanation:

The number of tulips in each vase has to be multiples of 60

Multiples of 60 = 1 ,2, 3, 4, 5, 6, 10, 15, 20, 30 ,60

Answer:

Step-by-step explanation:

since the 2 functions equal each other:

-2x + 3 = 4x - 9

add -2x to both sides

3 = 6x - 9

add 9 to both sides

12 = 6x

divide by 6

2 = x

you have x, now find y, you just need to plug 2 into one of the equations instead of both bc they both equal the same anyway

-2(2) + 3

-4 + 3

-1 = y

Now we'll find x + y, input them and it's 2 + (-1), which is 1

Step-by-step explanation:

We would be eliminating -9x from the equations.

Thus, we need to make the (-3x) into (-9x) in the first equation.

-9x ÷ -3x = 3

After that, you should be able to solve the equations:

-3x - 2y = 2

Equation 1×3: -9x - 6y = 6
