Answer:
Hello! answer: x = 4
Step-by-step explanation:
Because this is a 180 degree angle it will add up to 180 so 8 × 4 = 32 and 32 + 120 = 152 and 7 × 4 = 28 and 28 + 152 = 180 so 4 is x HOPE THAT HELPS!!
180 degree line-
180 = (8x + 120)
-120
60 = 8x
/8
7.5
x = 7.5
7(7.5) = 52.5

The sum of two consecutive odd numbers is twelve squared. What is the product of the two numbers
Answers
Answer:
Step-by-step explanation:
let the numbers be 2x+1,2x+3
2x+1+2x+3=12²
4x+4=144
4x=144-4=140
x=35
so numbers are 2×35+1=71
and 2×35+3=73
so numbers are 71,73
product=71×73=5183

-2+(-7) is basically -2-7.
This means that you go 7 units to the left of -2.
Answer:
Choice C.
Step-by-step explanation:
So the question -2 + (-7). Note that a negative cancels out a positive so it is,
-2-7
This would equal 9.
Since smaller numbers are futher to the left on the number line, it would be 7 to the left of -2, being Choice C.

The data modeled by the box plots represent the battery life of two different brands of batteries that Mary tested. A) What is the median value of each data set? B) Compare the median values of the data sets. What does this comparison tell you in terms of the situation the data represents? ( Answer A and B) Will Mark Brainliest if correct answer.
Answers
Answer:
X = 13 ; Y = 16
Median Y > Median X
Battery Y lasts longer and hence better than Battery X.
Step-by-step explanation:
From the box plot, median value is the point marked by the vertical line in between the box located between the whiskers.
Median :
Brand X = 13
Brand Y = 16
This median value depicts that, average battery life of brand X batteries is 13 hours while that of brand Y batteries is 16 hours ; Median value of Y is greater Than median value of X ;
This means Brand Y batteries lasts longer on average than Brand X batteries.
2x-y=-1 , 3x-y=2 solve by substition
Answers
Answer:
x = 3, y = 7
or (3,7)
Step-by-step explanation:
We are given the system of equations below:
[tex] \large{ \begin{cases} 2x - y = - 1 \\ 3x - y = 2 \end{cases}}[/tex]
We are required to solve the system by substitution method. What we have to do is to isolate either x-term or y-term so we can use the method. I will be isolating y-term because it is faster due to having 1 as a coefficient.
By isolating y-term, just pick one of the given equations to isolate. No need to isolate the whole system. (I will be isolating y-term of the first equation.)
[tex] \large{ \begin{cases} y= 2x + 1\\ 3x - y = 2 \end{cases}}[/tex]
Then we substitute y = 2x+1 in the second equation.
[tex] \large{3x - (2x + 1) = 2}[/tex]
Use the distribution property.
[tex] \large{3x - 2x - 1 = 2}[/tex]
Isolate x-term to solve the equation.
[tex] \large{x = 2 + 1} \\ \large{x = 3}[/tex]
Since we are solving a system of equations. We have to solve for both x-value and y-value to complete. We have already found x-value, but nor y-value yet. Therefore, our next step is to substitute the value of x that we solved in any given equations. It's recommended to substitute in an equation that doesn't have high coefficient value. So I will be substituting x = 3 in the first equation.
[tex] \large{2x - y = - 1} \\ \large{2(3) - y = - 1} \\ \large{6 - y = - 1}[/tex]
Isolate and solve for y-term.
[tex] \large{6 + 1 = y} \\ \large{7 = y} \\ \large{y = 7}[/tex]
Since we substitute x = 3 and get y = 7. We can write in ordered pairs as (3,7)
Hence, the solution is (3,7)
Suppose Bank One offers a certificate of deposit that pays $5,000 in four years for exchange for $4,000 today. What interest rate is Bank One offering?"
Answers
Answer:
Bank One is offering a simple interest rate of 6.25% per annum.
Step-by-step explanation:
Given that Bank One offers a certificate of deposit that pays $ 5,000 in four years for exchange for $ 4,000 today, to determine what interest rate is Bank One offering the following calculation must be performed:
(5000 - 4000) / 4 = X
1000/4 = X
250 = X
4000 = 100
250 = X
250 x 100/4000 = X
25000/4000 = X
6.25 = X
Therefore, Bank One is offering a simple interest rate of 6.25% per annum.

What is expression?"It is a combination of numbers, variables, mathematical operations (such as addition, subtraction, multiplication or division etc.)"
What is exponent?"It is a number that shows how many times another number is to be multiplied by itself"
Exponent formulas:[tex]a^m\times a^n=a^{m+n}\\a^m\div a^n=a^{m-n}[/tex]
For given example,
We solve each expression using exponents formulas.
Consider the first expression,
[tex]\Rightarrow (4.3\times 10^6).(9.8\times 10^{-4})=42.14\times 10^(6-4)\\\\\Rightarrow (4.3\times 10^6).(9.8\times 10^{-4})=42.14\times 10^(2)\\\\\Rightarrow (4.3\times 10^6).(9.8\times 10^{-4})=\bold{4214}[/tex]...........................(1)
Consider the second expression,
[tex]\Rightarrow (2.9\times 10^7).(1.6\times 10^{-9})=4.64\times 10^{7-9}\\\\\Rightarrow (2.9\times 10^7).(1.6\times 10^{-9})=4.64\times 10^{-2}\\\\\Rightarrow (2.9\times 10^7).(1.6\times 10^{-9})=\bold{0.0464}[/tex] .........................(2)
Consider the third expression,
[tex]\frac{(4.7\times 10^3).(8.6\times 10^{-7})}{(3.8\times 10^-4).(6.1\times 10^2)}\\\\ = \frac{40.42\times 10^{3-7}}{23.18\times 10^{-4+2}} \\\\= \frac{40.42\times 10^{-4}}{23.18\times 10^{-2}}\\\\=\frac{40.42}{23.18}\times 10^{-4+2} \\\\=1.74\times 10^{-2}\\\\=\bold{0.0174}[/tex] .....................(3)
Consider the fourth expression,
[tex](4.9\times 10^3).(7.4\times 10^{-6})\\\\=36.26\times 10^{3-6}\\\\=36.26\times 10^{-3}\\\\=\bold{0.03626}[/tex] ....................................(4)
Now we solve the last expression,
[tex]\frac{(3.9\times 10^{5}).(8.7\times 10^{-3})}{(3.7\times 10^{-5}).(2.9\times 10^{8})}\\\\= \frac{(33.93\times 10^{5-3})}{(10.73\times 10^{-5+8})}\\\\= \frac{(33.93\times 10^{2})}{(10.73\times 10^{-3})}\\\\= \frac{33.93}{10.73}\times 10^{2+3}\\\\= 3.162162\times 10^5\\\\=\bold{316216.2}[/tex] ..........................(5)
From (1), (2), (3), (4) and (5),
The solutions of the mathematical expressions from least to greatest would be,
0.0174, 0.03626, 0.0464, 4214, 316216.2
