One number is 7 more than another. If the sum of the two numbers is 165, find the two numbers.
The smaller number is
The larger number is 1
x+7+x=165
2x+7=165
2x+7-7=165-7
2x=158
2x÷2=158÷2
x=79
79+7+79=165
Which equation does the graph below represent?
A coordinate grid is shown. The x-axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y-axis values are from negative 10 to positive 10 in increments of 2 for each grid line. A line is shown passing through the ordered pairs negative 4, 8 and 0, 0 and 4, negative 8.
y = −2x
y = fraction negative 1 over 2x
y = 2x
y = fraction 1 over 2x
Answer:
y = -2
Step-by-step explanation:
The graph passes through (0,0) and (-1,2).
The equation of a line passing through the origin is of the form,
y = mx
We now substitute (-1,2) to obtain,
2 = -m
This implies that,
m = -2
The equation is
y = -2

What is the best choice for the common denominator in this problem?
1/5 + 2/6
Answer:
The common denominator is x30
Step-by-step explanation:
Answer:
[tex]30[/tex]
Step-by-step explanation:
The best choice for a common denominator will always be the least common multiple of the two denominators. In this case, the least common multiple of 5 and 6 is 30, so [tex]\boxed{30}[/tex] is the best choice.

Answer:
- 5 [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
- 3 [tex]\frac{1}{2}[/tex] - 1 [tex]\frac{5}{6}[/tex] ( change to improper fractions )
= - [tex]\frac{7}{2}[/tex] - [tex]\frac{11}{6}[/tex] ( multiply numerator/denominator of first fraction by 3 )
= - [tex]\frac{7(3)}{2(3)}[/tex] - [tex]\frac{11}{6}[/tex]
= - [tex]\frac{21}{6}[/tex] - [tex]\frac{11}{6}[/tex]
= [tex]\frac{-21-11}{6}[/tex]
= [tex]\frac{-32}{6}[/tex]
= - [tex]\frac{32}{6}[/tex]
= - 5 [tex]\frac{2}{6}[/tex]
= - 5 [tex]\frac{1}{3}[/tex]
suppose that p is the probability that a randomly selected person is left handed. The value (1-p) is the probability that the person is not left-handed. In the sample of 100 people, the function V(p)= 1000 p(1-p) represents the variance of the number of left-handed people in a group of 100.
a) What value of p maximizes the variance?
b) What is the maximum variance?
Answer:
a) 1/2
b) 250
Step-by-step explanation:
The start of the question doesn't matter entirely, although is interesting to read. What we are trying to do is find the value for [tex]p[/tex] such that [tex]1000p(1-p)[/tex] is maximized. Once we have that [tex]p[/tex], we can easily find the answer to part b.
Finding the value that maximizes [tex]1000p(1-p)[/tex] is the same as finding the value that maximizes [tex]p(1-p)[/tex], just on a smaller scale. So, we really want to maximize [tex]p(1-p)[/tex]. To do this, we will do a trick called completing the square.
[tex]p(1-p)=p-p^2=-p^2+p=-(p^2-p)=-(p^2-p+1/4)-(-1/4)=-(p-1/2)^2+1/4[/tex].
Because there is a negative sign in front of the big squared term, combined with the fact that a square is always positive, means we need to find the value of [tex]p[/tex] such that the inner part of the square term is equal to [tex]0[/tex].
[tex]p-1/2=0\\p=1/2[/tex].
So, the answer to part a is [tex]\boxed{1/2}[/tex].
We can then plug [tex]1/2[/tex] into the equation for p to find the answer to part b.
[tex]1000(1/2)(1-1/2)=1000(1/2)(1/2)=1000*1/4=250[/tex].
So, the answer to part b is [tex]\boxed{250}[/tex].
And we're done!

The local community center hosted a marathon as a fundraiser. Runner A completed the marathon with a time of 4.37 hours. Runner B completed the marathon in 4.29 hours. Which runner completed the race faster (by having a lower time)? Explain how you know. (100 points + brainliest)
Based on the information given in the question, the completion time of runner B is lower than that of Runner A ; Hence, runner B completed the race faster.
Given the running time of two runners :
Runner A = 4.37Runner B = 4.29The runner with the lesser running time will complete the marathon faster as this means he has a higher speed.
Comparing the running times of both runners :
4.37 > 4.29Therefore, Runner B completed the race faster than runner A.

4(y-2)=-0.6(y+0.3 what is the answer and how to do it
Answer:Solution for 0.3(y-2)+0.4y=0.3y-0.6 equation:
0.3(y-2)+0.4y=0.3y-0.6
We move all terms to the left:
0.3(y-2)+0.4y-(0.3y-0.6)=0
We add all the numbers together, and all the variables
0.4y+0.3(y-2)-(0.3y-0.6)=0
We multiply parentheses
0.4y+0.3y-(0.3y-0.6)-0.6=0
We get rid of parentheses
0.4y+0.3y-0.3y+0.6-0.6=0
We add all the numbers together, and all the variables
0.4y=0
y=0/0.4

Justin is taking a taxi cab to pick up his car from the auto shop. The taxi charges an initial fee of $5.00 and additional $2.50 for each mile the taxi drives. Write an equation using x as the number of miles, to determine how many miles the taxi drove if Justin spent $25.00. Use your equation for the number of miles. (Define the variable please, write an equation, and solve & label:))
Answer:
x = 8
Step-by-step explanation:
Given the initial fee of $5.00, and the additional cost of $2.50 for every mile the taxi drives:
We can establish the following cost function:
C(x) = 2.50x + 5.00
Where:
C(x) = total cost of taxi fare (same as the variable, "y" in linear equation)
x = number of miles driven
$5.00 = initial or flat fee (same as the y-intercept, "b," in linear equation).
We can find out the number of x miles the taxi drove for the $25.00 total cost that Justin paid for the fare:
C(x) = 2.50x + 5.00
$25 = 2.50x + 5.00
Subtract 5.00 from both sides of the equation:
$25 - 5.00 = 2.50x + 5.00 - 5.00
$20 = 2.50x
Divide both sides by 2.50 to solve for x:
[tex]\frac{20}{2.50} = \frac{2.50x}{2.50}[/tex]
8 = x
Justin spent $25 for a taxi ride that travelled for 8 miles.

What would be the range of possible whole number values (x) for a 3rd side of the triangle with two sides of 5 in. and 8 in.?
& Name one possible value for a third side?
Correct Answer Only
Answer:
Range of the third side of a triangle
Step-by-step explanation:
Any one side of a triangle must be shorter than the sum of the other two sides. Therefore, the third side length x must be between 5 and 35, not including those endpoints: 5 < x < 35. All whole numbers satisfying this range would form a triangle.
20 is a possible value for a third side

write the log equation as an exponential equation. you do not need to solve for x.
Answer:
[tex]5^{1/6} =2x[/tex]
Step-by-step explanation:
Log and exponential forms are inverses. Additionally, the information from one can be used to write in it another form. In a log equation, there are three parts. The formula is [tex]log_{b}(x)=y[/tex]. The formula for exponential equations is [tex]b^y=x[/tex]. This means to find this equation in exponential form write 5 as the base, 1/6 as the power, and 2x as the other side of the equation. This looks like, [tex]5^{1/6} =2x[/tex].

Answer:
1st one: Reflection
2nd one: Rotation
3rd one: Rotation
4th one: Translation
Step-by-step explanation:
1: These figures are flipping across the y-axis, meaning it's a reflection.
2: This figure rotated 90° clockwise, so it's a rotation.
3: This figure rotated 180° both clockwise and counterclockwise, so it's a rotation.
4: This figure just shifted down and to the right, so it's a translation.
