Answer:
x = -5
Step-by-step explanation:
Simplify: 2x + 8 - 5 = -7Subtract 8 from each side, so it now looks like this: 2x - 5 = -15Add 5 to each side, so it now looks like this: 2x = -10Divide each side by 2, to cancel out the 2 next to x. It should now look like this: x = -5I hope this helps!

What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
given that,
a capacity of 25 fluid Ounces more than a capacity of 3 cups
we have to find why it is correct.
now, we get,
if we divide 25 by 8
i.e. 25/8
now, we know,
24/8 = 3
so, 25/8 = 3.125
i.e. 25/8 > 3
as, we have, the result is greater than 3.
Hence, a capacity of 25 fluid Ounces more than a capacity of 3 cups is,
Because when you divide 25 by 8, the result is greater than 3.

Rice weighing 33/4 pounds was divided equally and placed in 4 containers. How many ounces of rice were in each?
Answer:
15 ounces
Step-by-step explanation:
33/4 ÷ 4 pounds.
= (4 × 3 + 3)/4 ÷ 4 pounds.
= 15/4 ÷ 4 pounds.
= 15/4 × 1/4 pounds.
= 15/16 pounds.
Now we know that, 1 pound = 16 ounces.
Therefore, 15/16 pounds = 15/16 × 16 ounces.
= 15 ounces

A population of voters contains 46% Republicans, 45% Democrats and the rest are Independents. Assume 50% of Republicans, 40% of Democrats, and 60% of Independents favor an election issue. A person chosen at random from this population is found to favor the issue in question. Find the conditional probability this person is a democrat. (Round off up to two decimal points.) Group of answer choices 0.18 0.51 0.71 0.39
Answer:
The probability is 0.18
Step-by-step explanation:
Here, we are interested in calculating a conditional probability;
Let the event that a voter is a Republican be R , the event that a voter is a Democrat be D and that a voter is an independent is I
Let the event that the election issue is favored be F
We have the following probabilities;
P(R) = 46% = 0.46
P(D) = 45% = 0.45
P(I) = 1-0.45-0.46 = 0.09
The conditional probability we want to calculate is;
P(D | F) which can be read as probability of event D given event F
From the question, we can identify the following conditional probabilities;
P(F|R) = 0.46 * 0.5 = 0.23 (0.5 is gotten from 50% = 50/100)
P(F | D) = 0.45 * 0.4 = 0.18
P( F | I) = 0.09 * 0.6 = 0.054
P(F) = 0.054 + 0.18 + 0.23 = 0.464
Mathematically; From Baye’s theorem
P( D | F) ={ P ( F | D) * P(D) }/ P(F)
P( D | F) = (0.18 * 0.45)/0.464 = 0.1745

A partial sum of an arithmetic sequence is given. Find the sum.
14 (3 + 0.26k) k = 0
Answer:
72.3
Step-by-step explanation:
Given that:
The arithmetic sequence:
[tex]\sum \limits ^{14}_{k=0} (3 + 0.26k)[/tex]
The first term of the sequence [tex]a_0[/tex] = 3 since k = 0
i.e (3 + 0.26(0)) = 3
The last term of the sequence [tex]a_{14}[/tex] = 6.64
i.e (3+ 0.26(14)
= (3 + 3.64)
= 6.64
Total no of terms = 15 i.e from 0 to 14
∴
The partial sum of the arithmetic sequence = [tex]\dfrac{Total \ no \ of \ terms }{2} \times (a_o+a_{15})}[/tex]
[tex]=\dfrac{15 }{2} \times (3+6.64)}[/tex]
= 72.3

What must be true of the units in two rates if one rate can be converted to the units of the other rate? In other words, the units of the
first rate are both/all distinct from that of the converted rate, but it still represents the same measurement?
Answer:
Yes, unit of the first rate can be be different from and second and still represent the same measurement/value.
Step-by-step explanation:
Yes, if we have two units rate and one rate is converted to another, both measurement will still remain the same even after the conversion but the rate will be different.
For example if we want to convert $2 to naira, note that the unit rates for are distinct but after conversion the amount of both money will be the same.
If $1 = #386
2$ = 2×#386
$2 = #772
Hence the measurement of $2 is equivalent to 386 naira even though the rates are distinct (naira and $)
4.Think about the expression (x-8)(x+4).
(a) For what values of x will this expression be
equal to zero? Show how you arrived at your
Answer
Answer:
x-8 to get the zero for the 8 you have to add it. And for the second part you have to subtract four from itself.
Step-by-step explanation:
From the expression (x - 8) (x + 4), the values of x need to be 8 or -4, for x to be equal to zero.
Given that:
(x - 8) (x + 4) = 0
The expression from above is the expanded form of a given quadratic equation.
To find the quadratic equation, we will use the values of one enclosed bracket to multiply the values of the other.
i.e.
(x -8) (x + 4) = 0
x² + 4x - 8x - 32 = 0
x² - 4x - 32 = 0
(So, this above expression shows the quadratic equation from which the roots of (x-8) (x-4) is being derived from)From the roots;
(x - 8) (x + 4) = 0
Let;
(x - 8) = 0 or (x +4) = 0
x - 8 = 0 or x + 4 = 0
x = 8 or x = -4
Therefore, we can conclude that the value of x needs to be 8 or -4 for x to be equal to zero.

L is the midpoint of KM. If KL = 2x and LM = x + 6, what is KL?
Answer:
KL = 12
Step-by-step explanation:
Given that L is the midpoint of KM , then
KL = KM , substitute values
2x = x + 6 ( subtract x from both sides )
x = 6
Thus
KL = 2x = 2 × 6 = 12
The measure of the segment KL is 12 units if the L is the midpoint of KM. If KL = 2x and LM = x + 6
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
L is the midpoint of KM. If KL = 2x and LM = x + 6.
Given that L is the midpoint of KM, then
From the question:
KL = KM
2x = x + 6
After simplification:
x = 6
KL = 2x
Plug x = 6 in the above equation:
KL =2(6)
KL = 12
The measure of the segment KL is 12 units.
Thus, the measure of the segment KL is 12 units if the L is the midpoint of KM. If KL = 2x and LM = x + 6.

Question 1 (1 point) 3 If the dimensions of the box are L= 5cm W=2.5cm H= 2.5 cm, and the a kernel is 0.6cm; How many kernels could fit inside of the box?
Answer:
145 kernels
Step-by-step explanation:
The dimensions of the box are L= 5cm W=2.5cm H= 2.5.
Size of a kernal is 0.6 cm
We need to find number of kernels that could fit inside of the box. Let n be such kernals. So,
[tex]n=\dfrac{\text{volume of box}}{\text{volume of one kernel}}[/tex]
Kernal is in the shape of cube
So,
[tex]n=\dfrac{\text{volume of cuboid}}{\text{volume of one cube}}\\\\n=\dfrac{LWH}{a^3}\\\\n=\dfrac{5\times 2.5\times 2.5}{(0.6)^3}\\\\n=144.67\\\\\text{or}\\\\n=145\ \text{kernels}[/tex]
Hence, 145 kernels could fit inside of the box.
