Answer:
X= -4
Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
Distribute the -2 to the parentheses:
-2(-4x - 3) -5x + 3 = -3
8x + 6 - 5x + 3 = -3
Add like terms:
3x + 9 = -3
Solve for x:
3x = -12
x = -4
So, the answer is x = -4

The cost for an upcoming field trip is $30 per student. The cost of the trip C, in dollars, is a function of the number of students x. Select all the possible outputs for the function defined by C(x)=30x.
Answer:
B. 30
D. 90
Step-by-step explanation:
The cost for an upcoming field trip is $30 per student. The cost of the field trip C, in dollars, is a function of the number of students x. Select all the possible outputs for the function defined by c(x) = 30x. A. 20 B. 30 C. 50 D. 90 E. 100
Given function:
C(x) = 30x
Where,
x = number of students
A. 20
C(x) = 30x
20 = 30x
x = 20/30
= 0.67
x = 0.67 student
B. 30
C(x) = 30x
30 = 30x
x = 30/30
x = 1 student
C. 50
C(x) = 30x
50 = 30x
x = 50/30
x = 1.67 students
D. 90
C(x) = 30x
90 = 30x
x = 90/30
x = 3 students
E. 100
C(x) = 30x
100 = 30x
x = 100/30
= 3.33
x = 3.33 students
Number of students, x should be an whole number
The possible for the function are
B. 30
D. 90

X^2+12=40 what number must you add to complete the square?
Answer:
Step-by-step explanation:
1) If you really meant X^2+12=40, then this simplifies to x^2 = 28, and therefore x = ±√28, or x = ±2√7.
2) If you meant X^2+12x=40:
a) Take half of the coefficient of x: that would be (1/2)(12), or 6.
b) Square this result, obtaining: 6² = 36
c) Add this 36 to x^2 + 12x + 40, and then subtract it: We get:
x² + 12x + 36 - 36 = 40, or x² + 12x + 36 = 76
We have to add 36, as indicated above, to "complete the square."

what is the value of the expression 2x + 5y when x = 3 and y = 2
Answer:
16
Step-by-step explanation:
If x = 3 and , y = 2.
2 x 3 = 6 and 5 x 2 = 10.
10 + 6 = 16
The value of the expression 2x + 5y when x = 3 and y = 2 is 16.
We have to determine, the value of the expression 2x + 5y when x = 3 and y = 2.
According to the question,
Expression; 2x + 5y
To determine the value of the expression calculation must be done in a single unit following all the steps given below.
The value of expression 2x+5y,
When the value of x = 3 and y = 2,
Therefore,
[tex]= 2x + 5y[/tex]
Substitute the value of x = 3 and y = 2 in the given expression,
[tex]= 2(3)+ 5(2)\\\\= 6 + 10\\\\= 16[/tex]
Hence, The value of the expression 2x + 5y when x = 3 and y = 2 is 16.

Answer:
X = 9.2
Step-by-step explanation:
You have to use the pythagorean theorm, which is a squared + b squared = c squared. Looking at the triangle, the vertical line is 6, and the horizontal is 7.
6squared + 7squared = c squared
85 = csquared
Take the square root of both sides to get rid of the squared on the c.
sqroot of 85 = 9.2
Find the percent.
33 is what percent of 40?
Answer:
33 is 83% of 40.
Step-by-step explanation:
33/40 = 0.825
0.825 equals 82.5%
82.5% rounded is 83%.
I hope this helps!
The required value of percentage is 82.5%. Here, 33 represents approximately 82.5 percent of the total value of 40.
To find the percent, we need to determine what portion of 40 is represented by 33. We can set up a proportion to solve this problem.
Let x represent the unknown percentage.
We can set up the proportion:
33/40 = x/100
To solve for x, we can cross-multiply and then divide:
= (33 × 100) / 40
= 3300/40
Apply division operation to get:
= 82.5
Therefore, 33 is 82.5 percent of 40.
This means that 33 is equivalent to 82.5 percent of 40.

Nina delivers newspapers. In the first week, she delivers 8 papers. In the second week, she delivers 32 papers. Which equation can Nina use to find how many times as many papers she delivered the second week as the first week?
Answer:
a) The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:
8x = 32
b) Nina delivered 4 times as many papers the second week as the first week
Step-by-step explanation:
From the question, we are told that:
Nina delivers newspapers.
In the first week, she delivers 8 papers.
In the second week, she delivers 32 papers.
Let x represent the number of times
The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:
8paper × x = 32 papers
8x = 32
Solving for x
8x = 32
x = 32/8
x = 4 times
Therefore, Nina delivered 4 times as many papers the second week as the first week
