In Buffalo New York the temperature was 10f in the morning if the temperature rose 10f what is the temperature now? Use a vertical number line to find the number.
Answer:
The temperature now is 20°F
Step-by-step explanation:
The given parameters are;
The initial morning temperature in Buffalo New York = 10°F
The rise in temperature in Buffalo New York = 10°F
The current temperature in Buffalo New York = The initial morning temperature in Buffalo New York + The rise in temperature in Buffalo New York
∴ The current temperature in Buffalo New York = 10°F + 10°F = 20°F.

What is the value of v?
45(v−7)=2
Enter your answer as a mixed number in simplest form in the box.
v =
Answer:
The solution is: v = [tex]9\frac{1}{2}[/tex]
Step-by-step explanation:
Given equation is:
[tex]\frac{4}{5}(v-7) = 2[/tex]
The given equation is a linear equation in one variable. The solution requires isolating v on one side of the equation. Simple equality properties can be used to solve the equation.
So,
Multiplying both sides of equation with 5
[tex]5*\frac{4}{5}(v-7) =5* 2\\{4}(v-7) = 10[/tex]
dividing both sides by 4
[tex]\frac{4(v-7)}{4} = \frac{10}{4}\\v-7 = \frac{5}{2}\\[/tex]
Adding 7 on both sides
[tex]v-7+7 = \frac{5}{2}+7\\v = \frac{5+14}{2}\\v = \frac{19}{2}\\v = 9\frac{1}{2}[/tex]
Hence,
The solution is: v = [tex]9\frac{1}{2}[/tex]
Given g(x) = ln x, is it true that if u>0 and v>0 g(u) = 2g(v), then u=v?
Justify your answer.
Will give brainliest answer
Answer:
FalseStep-by-step explanation:
Giveng(x) = ln xTo findg(u) = 2g(v)Solutiong(u) = ln u2g(v) = 2ln vComparing
g(u) = 2 g(v)ln u = 2ln vln u = ln v²u = v²This is not same as u = v, so the answer is false

Andrea has $18 to spend. She spent $6.50, including tax, to buy a notebook. She needs to save $5.75, but she wants to buy a snack. If candy bars cost $1.15 per package including tax, what inequality would show the maximum number of packages that Andrea can buy? Solve your inequality by showing your work and steps. (10 points)
Answer:
is the missing number
Step-by-step explanation: The missing number would have to determine what the ineqaulities are
Hope this helps
Answer:
The number of candy packages is going to be represented by the variable c.
6.50 – 5.75
18 – 6.5 - 1.15c ≥ 5.75
11.5 - 1.15c ≥ 5.75
Subtract 11.5 from both sides
-1.15c ≥ -5.75
Divide both sides by -1.15 and flip the sign.
You answer be c ≤ 5

A taxi service charges a flat fee of $1.25 and $0.75 per mile. If Henry has $14.00, which of the following shows the number of miles you can afford to ride in the taxi?
Answer:
The total cost of the taxi service is the flat free and the total amount that is based on the distance. Let x be this distance. The equation that would best represent the situation is,
1.25 + 0.75x = 14
Solving for x gives the answer of 17. Thus, Henri can afford to travel 17 miles.

.A length, originally 9cm, is increased so that the ratio of the new length to the old length is 13:3. What is the new length
Answer:
The new length is 39 cm
Step-by-step explanation:
We will use the ratio method to solve the question
∵ A length, originally 9cm, is increased
∴ The original length = 9 cm
∵ The ratio of the new length to the old length is 13 : 3
→ That means the ratio is ⇒ New : Original is 13 : 3
∴ The ratio New : Original = 13 : 3
→ By using the ratio method
→ New : Original
→ 13 : 3
→ x : 9
→ By using cross multiplication
∵ x × 3 = 13 × 9
∴ 3x = 117
→ Divide both sides by 3
∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{117}{3}[/tex]
∴ x = 39
∵ x represents the new length
∵ x = 39
∴ The new length is 39 cm

PLEASE HELP NOW ASAP Peyton is collecting data on the lunch habits of students at Nicholas Orem Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Nicholas Orem Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch? *
Answer:
1000 students buy a lunch
Step-by-step explanation:
14 bring lunch
20 buy lunch
There are 34 kids in the sample class (14 + 20)
14/34 = .412 = 41.2%
There are 1700 students.
14 / 34 = x / 1700 cross multiply
14 (1700) = 34x
23,800 = 34x Divide each side by 34
23800/34 = 34x/34
23800/34 = x
700 = x
So 700 students bring a lunch.
1700 - 700 = 1000
1000 students buy a lunch.
