Answer:
x = 3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2x+25=x+16
Step 2: Subtract x from both sides.
−3x+25=16
Step 3: Subtract 25 from both sides.
−3x=−9
Step 4: Divide both sides by -3
x=3
The temperature is at -2 F at 6A.M. During the next three hours, the temperature increases to 15F. What is the temperature at 9A.M. Enter your answer in integer form
Answer:
Temperature at 9 A.M = 13° F
Step-by-step explanation:
Given:
Temperature at 6 A.M = - 2° F
Temperature increases in 3 hours = 15° F
Find:
Temperature at 9 A.M
Computation:
Temperature at 9 A.M = Temperature at 6 A.M + Temperature increases in 3 hours
Temperature at 9 A.M = - 2° F + 15° F
Temperature at 9 A.M = 13° F
Salim and Anna met when they were in first grade, and they have been best friends for 10 years. Which part of this sentence is a clause?
Here, we are required to identify which part of the sentence is a clause .
The clause in the sentence is "Salim and Anna met when they were in first grade"
First, we must know that a clause is simply defined as a group of words containing a subject and predicate and functions as a part of a complex or compound sentence.
The sentence "Salim and Anna met when they were in first grade, and they have been best friends for 10 years." is a compound sentence.
And, the "Salim and Anna met when they were in first grade" part of the sentence is a clause as it has a subject which is "Salim and Anna" and a predicate which is the rest of the sentence i.e "met when they were in first grade"

Miss K wants to get Portillos with 5 of her teacher
friends. She decides to split a pizza and 6 drinks. If the
pizza cost $11.50, and they spend a total of $18.50,
how much does one drink cost?
Show ALL work in this box!
Answer: $1.17 per drink
Step-by-step explanation:
Let x=the cost of one drink
11.5+6x=18.5
subtract 11.5 on both sides
11.5+6x-11.5=18.5-11.5
6x=7
Divide 6 on both sides
6/6 x=7/6
x=7/6
7/6≈$1.17

The perimeter of a right triangle is 25 meters and the area is 20 square meters. The length of the sides are each multipled by 3. What is the are of the new triangle
Answer:
The area of the new triangle is 180 m²
Step-by-step explanation:
let the height of the triangle = h
let the base of the triangle = b
The area of right triangle is given by;
A = ¹/₂bh
20 = ¹/₂bh
If we multiple each side of the triangle by 3, the new area of the triangle will be as follows;
A= ¹/₂(3b)(3h)
A = ¹/₂(9) (bh)
A = 9(¹/₂bh)
A = 9(20)
A = 180 m²
Therefore, the area of the new triangle is 180 m²

What’s the answer to this question?
Answer:
report that dude the answer is:
-7.75
Step-by-step explanation:
(1/2)^2 - 6(2 - 2/3)
First we get rid of the exponent 2 by muliplying the (1/2) two times.
(1/2)×(1/2) = 1/4
Now we have:
1/4 - 6(2 - 2/3)
Now we solve the equation in the other paraenthesis:
(2 - 2/3) = 1 1/3
Now we plug it back in:
1/4 - 6(1 1/3)
Now we mulitply the 6 with the fraction 1 1/3 in the paraenthesis:
6(1 1/3) = 8
Now we plug it back in:
1/4 - 8
Now finally solve this fraction:
-7.75

What is the solution set for the inequality?
-6x+9>7x+74
Answer:
Step-by-step explanation:
- 6x + 9 > 7x + 74
Treat them as being equal first.
Subtract 9 from both sides.
- 6x + 9 - 9 > 7x + 74 - 9
- 6x > 7x + 65
Subtract 7x from each side
- 6x - 7x > 7x - 7x + 65
- 13x > 65
Divide each side by -13
- 13x / -13 > 65 / -13
x < -5
So x hust be smaller than -5 meaning -6 works but -4 doesn't.
jessica is saving money for a new sailboat. she has already saved $1000 and plans to save $150 per week. this situation can be represented by the function f(x)=1000+150x, where x is the number of weeks. how much money has jessica saved after 12 weeks
Answer: $2800
Step-by-step explanation:
if the function is f(x) and shes already saved $1000 plug in the functions, or in other words plug in x for weeks.
1000 + 150 x
(plug in x)
1000 + 150 x 12
so now you do 150 x 12 which equels 1800
then add how muh shes saved and thats will be your total.

What is geometry?Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial properties such as figure distance, shape, size, and relative position.
Given that a box with no top that has a volume of 1000 cubic inches is to be constructed from a 22 x 30-inch sheet of cardboard by cutting squares of equal size from each corner and folding up the flaps.
The size of the square cut from each corner will be calculated as,
Volume = L x H x W
1000 = 22 x 30 x H
H = ( 1000 ) / ( 660 )
H = 1.538 or 1.369 inches
Therefore, the size will be 1.369 inches.

How much total money would Hailey have to pay in a month in which she downloaded 40 songs? How much would she have to pay if she downloaded ss songs?
Answer:
The total is: 74$
Step-by-step explanation:
1.50$ times 40 equals 60. Then you have to add up the cost you usually get per month which is 14$. 60 plus 14$ = 74$

Ankit makes 74% of the free throws he takes in his basketball league. If he is fouled on a three-point shot and gets three free throws, what is the approximate probability he will make all three shots?
The approximate probability that Ankit will make all three shots is 0.405 or 40.5%.
What is binomial distribution?A probability distribution known as the binomial distribution is used to characterize the number of successes in a certain number of independent trials, where each trial has only one of two potential outcomes (success or failure) and the chance of success is constant across all trials. For determining the likelihood of achieving a certain number of successes in a set number of trials, it is utilised.
Given, Ankit makes 74% of the free throws.
Using binomial distribution we have:
[tex]P(X=k) = (n C k) * p^k * (1-p)^{(n-k)}[/tex]
For k = 3 we have:
[tex]P(X=3) = (3 C 3) * 0.74^3 * (1-0.74)^{(3-3)}\\\\P(X=3) = 0.74^3[/tex]
P(X=3) ≈ 0.405
Hence, the approximate probability that Ankit will make all three shots is 0.405 or 40.5%.
