Ok please somebody help me “For every 330 feet a person travels up a mountain the temperature drops 1 °F. If the temperature is 78 °F. at the base of a 6,270- foot mountain, what is the temperature at the peak?”
Factor the linear expression 15x-10 using the greatest common factor of the terms
A.5(3x + 2)
B.5(3x - 10)
C.5(3x- 2)
D.15(x- 2)
Answer:
The answer would be A (3x+2).
Answer: 5(3x-2) - Choice [C]
Step-by-step explanation:
Hii, do you need to factor the expression 15x-10? Np! (:
Note that 15x and -10 have a 5 in common.
To factor it out, we divide 15x and -10 by 5
3x-2 is what we obtain
Next we put parentheses around 3x-2
(3x-2) is what we obtain.
Finally, we put 5 outside the parentheses
5(3x-2)
Voila! There's our answer, cheers! (:

Solve the simultaneous equations
2x + 3y = 6
7x – 2y = 1
Answer:
x=0.6, y=1.6
Step-by-step explanation:
Multiply the first equation by 2 and the second equation by 3, so we can cancel out the y terms:
4x+6y=12
21x-6y=3
Add these 2 equations together:
25x=15
x=0.6
Now, to solve for y, plug x back into any of the equations above:
2(0.6)+3y=6
1.2+3y=6
3y=4.8
y=1.6
Answer:
Below in bold.
Step-by-step explanation:
2x + 3y = 6 Multiply by 2:
7x – 2y = 1 Multiply by 3:
4x + 6y = 12
21x - 6y = 3 Adding:
25x = 15
x = 0.6. Substitute x = 0.6 into the first equation:
2*0.6 + 3y = 6
3y = 6 - 1.2 = 4.8
y = 1.6.

What is the Lcm of 18 and 32
Answer:
The LCM of 18, and 32 is
Answer: The LCM is 288.
Step-by-step explanation:
To find the least common multiple of 18 and 32, you will find the multiples of 18 and 32 and look for least multiple number that matches 18 and 32.
Multiples of 18 are: 18,36,54,72,90,108,126,144,162,180,198,216,234,252,270,288
Multiples of 32 are: 32, 64,96,128, 160,192,224, 256, 288
The last digit 288 is the least multiple number that appears in both multiples for the two numbers.
A student was working on the problem below: Mr. Braun has $85.00 to spend on pizzas and soda pop for a picnic. Pizzas cost $11.00 each and the drinks cost $0.90 each. Four times as many drinks as pizzas are needed. What is the maximum number of pizzas that Mr. Braun can buy? The student began by writing the let statement: Let x = # of pizzas Then the student wrote the inequality: \displaystyle 11.00(x)+0.90(4x)\ge85.0011.00(x)+0.90(4x)≥85.00 The student made a MISTAKE. Describe the student's error and explain how you know it's wrong. (Do not solve the inequality.)
Answer:
11x + 0.90(4x) ≤ $85
Step-by-step explanation:
Let the number of pizzas be represented by p
Let the number of sodas be represented by s
Mr. Braun has $85.00 to spend on pizzas and soda pop for a picnic. Pizzas cost $11.00 each and the drinks cost $0.90 each.
$11 × p + $0.90 × s = $85
11x + 0.90y ≤ $85.......Equation 1
Four times as many drinks as pizzas are needed.
4p = s
We substitute 4p for s in Equation 1
11x + 0.90(4p) ≤ $85
What is the maximum number of pizzas that Mr. Braun can buy?
The maximum number of pizzas Mr Braun can buy =
11x + 0.90(4p) ≤ $85
The student's error has to do with the inequality sign. The student used greater than or equal to.
The correct sign is less than or equal to because Mr Braun has only $85 to spend.

Which value of X will allow the following set of ordered pairs to represent a function? (3,7) (2,6) (x,8) (1,5)
Answer:
[tex]x[/tex] must be number different to 1, 2 and 3 to guarantee that given relation is a function.
Step-by-step explanation:
From Function Theory, we know that a function is a relation in which all domain elements are not related to at least two different elements from range. Which means that [tex]x \in \mathbb{R}-\{1,2,3\}[/tex], that is, that [tex]x[/tex] is a real number different to 1, 2 and 3.
Hence, we conclude that [tex]x[/tex] must be number different to 1, 2 and 3 to guarantee that given relation is a function.

write an equation of the line with the given information. m. 4. A(-1.-5)
Answer:
An equation of the line with the given information with
m = 4 and point A(-1, -5) is:
[tex]y=4x-1[/tex]Step-by-step explanation:
As the equation of a line in point-slope form is given by:
[tex]y-y_1=m\left(y-x_1\right)[/tex]
where m is the slope.
Given:
the slope m = 4 the point A(-1, -5)Substituting the values in the equation of a line in point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y\:-\:\left(-5\right)\:=\:4\:\left(x\:-\:\left(-1\right)\right)[/tex]
[tex]y+5=4\left(x+1\right)[/tex]
subtract 5 from both the sides
[tex]y+5-5=4\left(x+1\right)-5[/tex]
[tex]y=4x-1[/tex]
Therefore, an equation of the line with the given information
with m = 4 and point A(-1, -5) is:

Answer:
C. [tex] d = \frac{at^2}{2} [/tex]
Step-by-step explanation:
Given:
[tex] t = \sqrt{\frac{2d}{a}} [/tex]
Required:
Make d the subject of the formula.
SOLUTION:
[tex] t = \sqrt{\frac{2d}{a}} [/tex]
Square both sides
[tex] t^2 = (\sqrt{\frac{2d}{a}})^2 [/tex]
[tex] t^2 = \frac{2d}{a} [/tex]
Multiply both sides by a
[tex] a*t^2 = \frac{2d}{a}*a [/tex]
[tex] at^2 = 2d [/tex]
Divide both sides by 2
[tex] \frac{at^2}{2} = \frac{2d}{2} [/tex]
[tex] \frac{at^2}{2} = d [/tex]
[tex] d = \frac{at^2}{2} [/tex]
Juan is three times as old as Gabe and Gabe is six years older than Catherine. If the sum of their ages is 149, how old is each person? Define a variable, write an equation, solve the equation, and answer in a complete sentence.
Answer:
Juan = 93 years.
Gabe = 31 years.
Catherine = 25 years.
Step-by-step explanation:
Let the age of Juan = J
Let the age of Gabe = G
Let the age of Catherine = C
Translating the word problem into an algebraic equation, we have;
[tex] J = 3G[/tex] ..........equation 1
[tex] G = C + 6 [/tex] ........equation 2
[tex] J + G + C = 149 [/tex] ........equation 3
We would solve the linear equations by using the substitution method;
Substituting equation 2 into equation 1;
[tex] J = 3(C + 6)[/tex]
[tex] J = 3C + 18[/tex] ........equation 4
Substituting equation 2 and equation 4 into equation 3;
[tex] (3C + 18) + (C + 6) + C = 149 [/tex]
Simplifying the equation, we have;
[tex] 5C + 24 = 149[/tex]
[tex] 5C = 149 - 24[/tex]
[tex] 5C = 125[/tex]
[tex] C = \frac {125}{5}[/tex]
C = 25 years.
To find G; from equation 2
[tex] G = C + 6[/tex]
Substituting the value of "C" into equation 2, we have;
[tex] G = 25 + 6[/tex]
G = 31 years.
To find J; from equation 1
[tex] J = 3G [/tex]
Substituting the value of "G" into equation 1, we have;
[tex] J = 3 * 31[/tex]
J = 93 years.
Therefore, Juan is 93 years old, Gabe is 31 years old and Catherine is 25 years old.
