Answer:
a=-1.5 (lmk if im incorrect)
Step-by-step explanation:
-16 - 7(2a + 3) = 23 - 2a
-16-(14a+21)=23-2a
5-14a=23-2a
5=23+12a
-18=12a
-18/12 is -1.5
a=-1.5
Answer: -5
Step by Step Explanation:
-16-7(2a+3)=23-2a distributive prop
-16-14a-21=23-2a add common factors
-37-14a=23-2a add 37 to both sides
-14a=60-2a add 2a to both sides
-12a=60 divide -12 from both sides
a=-5

What is an equation of the line that passes through the point (5, 4) and is parallel to
the line 6x – 5y = 15?
Answers
Answer:
6x - 5y does not change as it is parallel so I put x = 5 & y = 4 in this equation and the result is 6 × 5 - 5 × 4 = 30 - 20 = 10 so the parallel equation is 6x - 5y = 10

In school ,there are 3 girls for every 2 boys . There are 650 students in total . How many students are girls ?
Answers
Answer:
Girls = 390
Step-by-step explanation:
Set up a proportion:
In a sample of 3:2, you have 5 kids in all.
So the the ratio of girls to kids in a sample of 5 is 2:5.
So set up a proportion:
(3/5) = (x/650)
5x = 650(3)
5x = 1950
x = 390
Answer:
390Step-by-step explanation:
Let number of boys be b and girls be g. Then we have:
g/b = 3/2g + b = 650From the first equation b is:
b = 2g/3Substitute b in the second equation
g + 2g/3 = 6505g/3 = 650g = 650*3/5g = 390Three choices tell you how to locate the point (3, -7.75). Which one does NOT?

what is the difference between 4x and x4? evaluate both of these expressions when x = 2
Answers
Answer:
There is no difference. 4x and x4 are both meaning 4 times x and x times 4
Step-by-step explanation:
If x = 2, then 4 x 2 = 8.
x4 is the same thing
2 x 4 = 8
Note:
When the numbers are there together, without an operation, it means multiplication.
The value of the expression 4x is 8.
The value of the expression [tex]x^4[/tex] is 16.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
4x and [tex]x^4[/tex]
For x = 2,
4x = 4 x 2 = 8
[tex]x^4[/tex] = [tex]2^4[/tex] = 2 x 2 x 2 x 2 = 16
Thus,
The values of the expression are 8 and 16.
