Step-by-step explanation:

You have the correct answer. The sides are cut in half. 16 and x are in the same ratio 2:1

16 / 8 = 2:1

Answer:

x=24 or 25

Step-by-step explanation:

90% is x=24

89.999999 repeat% is x =25

The inequality is represented by the given graph is y ≤ -x/3+1.

The correct option is B.

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.

We have,

A graph of an inequality, passing by (0, 1) and (3, 0).

A and D are eliminated since the line is solid.

C is disregarded because the line is shaded below as well.

Then, the inequality will be y ≤ -x/3+1

Hence, the inequality is represented by the given graph is y ≤ -x/3+1.

#SPJ7

Answer:

He would pay $287 if he races 39 times

Thus, the membership fee is $14.

Step-by-step explanation:

Linear Modeling

The situation described in the problem can be modeled as the equation of a line which has the form:

[tex]y=ax+b[/tex]

Where y is the cost of the course, x is the number of races, a is the cost per race, and b is the membership fee.

We know the course charges $7 per race, so a=7. Since your friend has raced x=28 times and paid y=210, we can find the value of b:

[tex]210=7(28)+b[/tex]

Operating:

[tex]210=196+b[/tex]

b=14

Thus, the membership fee is $14.

The linear model is now:

[tex]y=7x+14[/tex]

If he races x=39 times, your friend would pay:

[tex]y=7(39)+14=287[/tex]

y=287

He would pay $287 if he races 39 times

Answer:

200 pieces of candy.

Step-by-step explanation:

Let x represent the amount of candy we had to begin with.

We ate 70% or 0.7 of our starting amount x.

After eating 70% of x, we are left with 140 empty wrappers.

Therefore, 70% or 0.7 of x is 140. So, we can write the following equation:

[tex]0.7x=140[/tex]

To find the original amount of candy, we just have to solve for x.

So, let’s divide both sides by 0.7:

[tex]\displaystyle x=\frac{140}{.7}=200[/tex]

Therefore, we started out with 200 pieces of candy.

Answer:

C=12.8

On the caculator there are two buttons you need to press. 2nd and then x2. Once you press those add in 20.

You get 4.47 ROUND THAT to 4.5

12(2)+4.5(2)=C(2)

12×12=144 4.5×4.5=20.25

144+20.25=164.25

164.25=C(2)

On the caculator press 2nd and then x2

12.81=12.8

C=12.8

Answer:

(0, - 4)

Step-by-step explanation:

( - 6, - 6) , (9, - 1)

2 : 3

2 + 3 = 5

9 - ( - 6) = 15

15 ÷ 5 × 2 = 6

"x" coordinate is 0 (- 6 + 6 = 0)

5 ÷ 5 × 2 = 2

"y" coordinate is - 4 ( - 6 + 2 = - 4)

(0, - 4)

Answer: 88 cones.

Step-by-step explanation:

We know that:

price of a cone = $1.10

price of a sundae = $2.35

A total of 172 cones and sundaes were sold for $294.20

Then we can define two variables:

C = number of cones sold

S = number of sundaes sold.

C + S = 172 (the total number of sundaes and cones sold is 172)

C*$1.10 + S*$2.35 = $294.20  (that is how much the won).

Then we have the system of equations:

C + S = 172

C*$1.10 + S*$2.35 = $294.20

And we want to find how many cones were sold.

To solve this, we first need to isolate the other variable, S, in one of the equations, i will isolate S in the first equation:

S = 172 - C

Now, let's replace this in the second equation:

C*$1.10 + (172 - C)*$2.35 = $294.20

Now we can solve this for C, and find the number of cones that were sold.

C*$1.10 + $404.20 - C*$2.35 = $294.20

C*($1.10 - $2.35) = $294.20 - $404.20

-C*1.25 = -110

C = 110/1.25 = 88

88 cones were sold.

Answer:

1/6 that's the answer

Step-by-step explanation:

so you do 43/6-7=43/6-42/6=1/6

Answer:

Actually the answer is -⅙

Step-by-step explanation:

43/6 written differently is 7 ⅙, because the fraction 42/6 is the same as 7 (42÷6=7). But since your number is 43/6 you get

7 1/6.

your original number is larger than 7 but the question was what number you have to "add" to get to 7. so they number has to be a negative number.

like this:

43/6 + (-1/6) = 42/6. which you rewrite now as

43/6 - 1/6 = 42/6. and I explained that 42/6 is the same as 7.

Answer:

G

Step-by-step explanation:

Answer: the best coupon for this case is WELCOME25, and the cost will be $30.

Step-by-step explanation:

We know that:

Price for pans = $22

Price for pots = $9.

If the customer buys two pots and one pan, he would pay::

C = 1*$22 + 2*$9 = $40.

If the customer uses the coupon 2POTSFOR1

Then he will pay only one of the pots, and the total cost will be:

C = 1*$22 + 1*9 = $31.

If the customer uses the WELCOME25 coupon, then the cost will be a 75% of the original cost.

if 100% = $40

then:

 75% = C

Where

We can take the quotient of these equations and get:

 (C/$40) = (75%/100%)

C = (75%/100%)*$40

C = 0.75*$40 = $30

Then the best coupon for this case is WELCOME25, and the cost will be $30.

Answer:

If you take a look at, 1.5 kilometers you can see that Mercury from the Sun is 5.8, it is also asking how many more kilometers is the distance of earth, so if you look at 5.1 and D which is 5.7 you would add those last digits together and get 5.8 so therefore your answer could possibly be D) 5.7 ⋅ 109 kilometers
