Answer:
x=16
Step-by-step explanation:
Equations which are never true:
4.1 Solve : -2 = 0
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : x+16 = 0
Subtract 16 from both sides of the equation :
x = -16
One solution was found :
x = -16
Step-by-step explanation:
First distribute: -2x - 28 + 1 = 5
Now simplify: -2x - 27 = 5
Now addition property of equality: -2x = 5 + 27
Now simplify: -2x = 32
Now division property of equality: x = 32/-2
Simplify: x = -16
If you need it as a fraction then you can put - [tex]\frac{16}{1} \\[/tex]

Answer:
diameter is 5 circomerance is 31.4
Step-by-step
explain what is meant by the given formula:
a1=12
an=an-1-8
Step-by-step explanation:
that this is an arithmetic sequence of terms, where every term is created by adding (or subtracting) to/ from the previous term.
a1 is the starting value = 12
then
a2 = a1 - 8 = 12 - 8 = 4
a3 = a2 - 8 = a1 - 8 - 8 = -4
every term is 8 less than the previous term.
so, we see, we can express the nth term of the sequence also in terms of a1 :
an = an-1 - 8 = a1 + -8×(n-1) = a1 - 8×(n-1)

Answer:
2 colas and 4 hot dogs
Step-by-step explanation:
We presume the units of total satisfaction are additive for the two food items.
The maximum number of colas Joe can buy with his $8 is $8/($2/cola) = 4 colas. Since a cola costs twice what a hot dog costs, Joe can give up 1 cola and buy 2 hot dogs. Possible purchases of (colas, hotdogs) for $8 can be ...
(0, 8), (1, 6), (2, 4), (3, 2), (4, 0)
Of course, either the number of colas or the number of hot dogs (or both) could be less than these values.
The corresponding satisfaction units are added in the attached table. These combinations are highlighted in green. The maximum number of satisfaction units is found to be for 2 colas and 4 hot dogs. (49 satisfaction units)
_____
Satisfaction values below and to the right of the highlighted diagonal cannot be purchased with $8.

Answer:
y = 6/8x - 3/2
Step-by-step explanation:
In this case, since we don't yet know the exact fraction for the y-intercept, we will find the slope first.
To find slope, we will simply start at the first point that is given to us on the graph, and then count the units up and over until we reach the second point. (Remember rise/run)
Our slope is 6/8, because we went upwards 6 units and to the right 8 units.
Now, in order to find the y-Intercept, we will use the point slope formula⤵⤵⤵
[tex]y - y _{1} = m(x - x _{1})[/tex]
We will plug in one of the points that the line passes through. In this case we will use the first given point. The coordinates of the point are (-3,-2).
y - (-3) = 6/8 (x- (-2)) or we can just simplify this to:
y + 3 = 6/8 (x + 2)
To solve this, first distribute 6/8 among everything inside the parenthesis to get
y + 3 = 6/8x + 3/2 (6/8 × 2 = 12/8 then simplify to 3/2). Next we will subtract 3 on both sides to get
y = 6/8x - 3/2.
And there we go, we're done. Hope this helps you :)
You have a bag of different flavored candies. The probabilities of randomly selecting a particular flavor of candy are shown below:
Cherry | .245
Lime | .325
Lemon | .180
Orange | .215
Grapefruit | .035
Your buddy Earl likes the lime candies. He eats a bunch of them and hands the bag back to you. The complement of the event P(selecting a Lime candy from the bag) would:
A. become 0
B. stay the same
C. There isn't enough information to answer this question
D. increase
E. decrease
(according to a different site E. decrease isn't the answer)
The complement of the event P(selecting a Lime candy from the bag) would increase.
The probability of event P(selecting a Lime candy from the bag) would decrease after Earl eats a bunch of lime candies.
In essence, the complement of the event P(selecting a Lime candy from the bag), which is synonymous to the chance of not picking a Lime candy from the bag increases.

2^3 is the same as 2 × 2 × 2 which equals 8, and 2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 which equals 128.
8 × 128 = 1,024

In a pack of starbursts, 25% of the
pieces were pink. If there were 12
pieces that weren't pink - how many
pieces were in the entire package?
How many pieces were red?
Answer: 16 total starbursts.
Step-by-step explanation:
If 25% were pink, then 75% aren't pink. Let x be the total number of starbursts. We know that 75% of x = 12 (the ones that aren't pink). There is insufficient information to determine whether there is even one red starburst.
0.75x = 12
x = 12/(3/4)
x = 48/3
x = 16
There are 16 total starbursts:
25% are pink = 4 pink starbursts
75% aren't pink = 12 non pink starbursts
Total of 16 starbursts.
We can't answer how many were red. We aren't given any indication that there is even one red starburst. All we know is that 12 are not pink.

A transportation rental company charges $11.50 for a bicycle rental, plus an additional $2.50 per hour that the bicycle is rented. Partial hour rentals are allowed. The total charge for a certain rental is $20.25. How long was the bicycle rented? Enter your answer in the box.
Answer:
3 hours 30 minutes
Step-by-step explanation:
First hour,
All cost, $11.50+$2.50 =$14
remaining charge, $20.25-$14 =$6.25
partial hour,
$2.50 ÷ 2 = $1.25
remaining hour,
per hour, $6.25 ÷ $2.50 = 2.5 hours
total hour rented,
1+2.5 = 3.5 hours
or
0.5 × 60 minutes = 30 minutes
3 hours 30 minutes
3.5 hours was the bicycle rented.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Transportation rental company charges $11.50 for a bicycle rental, plus an additional $2.50 per hour that the bicycle is rented
11.50+2.50x
Partial hour rentals are allowed
The total charge for a certain rental is $20.25.
All cost, $11.50+$2.50 =$14
remaining charge, $20.25-$14 =$6.25
partial hour,
$2.50 ÷ 2 = $1.25
Remaining hour,
per hour, $6.25/$2.50 = 2.5 hours
Total hour rented, 1+2.5 = 3.5 hours
