whats the answer?
Step-by-step explanation:
The equation that represent the situation would be; 15+25d=t. Here the variable are d for distance and t for temperature.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that the surface temperature averages at 15 degrees Celsius and increases 25 degrees Celsius with each kilometer of depth.
We can conclude that the initial value is 15 it increases(+) by 25 to each kilometer(distance=d) of depth.
The equation becomes
15+25d=t.

help dont understand like its confusing one minute u add then substract like...
Answer:
53 degrees
Step-by-step explanation:
< will be angle UwU (using pc)
m<JKM = 151 degrees is the total angle combining m<1 and M<2
therefore, we subtract m<2 from m<JKM to find m<1
Here is the equation:
m<JKM = m<1 + m<2
151 = m<1 + 98 (substitute)
53 = m<1 (simplify the like term so we subtracted 98 on both sides)

party she is throwing,
(a) Represent the total amount of pizza that (b) Write your answer from (a) as a mixed
Maria is buying as a fraction. Do not number in simplest form. What does this
simply
answer tell you?
Answer:
Step-by-step explanation:
the pizza come in slices that are 1/8 each.
there are 36 slices, which means [tex]\frac{36}{288}[/tex]. so the simplest form is 1/8 as well. Maria bought 4 pizzas
The total amount of pizza Maria bought as a fraction is [tex]\frac{36}{4}[/tex] and 8 [tex]\frac{1}{2}[/tex] as a mixed number
Total amount bought = fraction of a slice x total slices bought
[tex]\frac{1}{4}[/tex] x 36 = [tex]\frac{36}{4}[/tex]
The above expression is an improper fraction
An improper fraction is a fraction in which the numerator is greater in value than the denominator
36 is greater than 4
A mixed number is a number that is made up of a whole a whole number and a proper fraction.
To convert to an improper fraction to a mixed number:
Divide the numerator by the denominator. The whole number is written down The remainder is the numerator and the denominator in retained[tex]\frac{36}{4}[/tex] = 8[tex]\frac{2}{4}[/tex]
When it is simplified it becomes 8 [tex]\frac{1}{2}[/tex]

Answer:
(5,1)
Step-by-step explanation:
if macs house if it’s 1/2 of the distance from Nate house to the park then half the distance of 10,2 is 5,1
The required coordinate of the max location is (4, 3).
Given that,
Nate wants to visit his friend max before going to the park. Nate's house is located at (-2,4), while the park is located at (10,2).
To find the location of macs house if it’s 1/2 of the distance from Nate's house to the park.
The midpoint is that point the line whose distance from both the ends of the line is equal.
Here,
Max lies 1/2 the distance of Nate and Park,
Location of max is given by,
= 10 - 2 / 2 and 4 + 2 / 2
= 8 / 2 and 6 / 2
= 4 and 3
Location of max is (4, 3)
Thus, the required coordinate of the max location is (4, 3).

Find the value of x and RT if RS=24 cm
RS = RT + TS = 24 cm
Let's plug our values into the equation above
24cm = 6x - 4 + 10cm
Combine like terms
24 cm = 6x + 6 cm
Subtract 6 cm from both sides
18 cm = 6x
Divide both sides by 6
3 = x
Plug 3 into the expression for RT
RT = 6(3) - 4 = 18 - 4 = 14 cm
Similarly, we know that TS = 10 cm and RS = 24 cm
24 cm - 10 cm = 14 cm
RT = 14 cm
14 cm = 6x - 4
Add 4 to both sides
18 cm = 6x
Divide both sides by 6
3 = x
Dariaun uses his credit card to buy a $3,000 laptop for college. The credit card
company charges him a simple interest rate of 18%.
How much does he owe the credit card company after six months?
Answer:
$3,270
Step-by-step explanation:
A = P(1 + rt)
First, converting R percent to r a decimal
r = R/100 = 18%/100 = 0.18 per year.
Putting time into years for simplicity,
6 months / 12 months/year = 0.5 years.
Solving our equation:
A = 3000(1 + (0.18 × 0.5)) = 3270
A = $3,270.00
The total amount accrued, principal plus interest, from simple interest on a principal of $3,000.00 at a rate of 18% per year for 0.5 years (6 months) is $3,270.00.

Answer:
4. x = 50
5. x = 5
Step-by-step explanation:
For question 4:
Multiply both sides: x + 35 = -15Move the constant to the right: x = -15 - 35Calculate: x = -50For question 5:
Move the constant to the right: -3x = -17 + 2Calculate the sum: -3x = -15Divide both sides: x = 5Answer:
4) x= -50
5) x= 5
Step-by-step explanation:
Number 5
Simplifying
-3x + -2 = -17
Reorder the terms:
-2 + -3x = -17
Solving
-2 + -3x = -17
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + -3x = -17 + 2
Combine like terms: -2 + 2 = 0
0 + -3x = -17 + 2
-3x = -17 + 2
Combine like terms: -17 + 2 = -15
-3x = -15
Divide each side by '-3'.
x = 5
Simplifying
x = 5
Number 4
x/5+7 = -3 // + 3
x/5+3+7 = 0
1/5*x+10 = 0 // - 10

x = -50
x = -50
