Answer:
4x+1
Step-by-step explanation:
The area is 12x2 + 3x in
The length is 3x
Formula is A=L*B
12x2 + 3x=3x*B
Divide both side by 3x
12x2+3x divide by 3x=B
4x+1=B
The express for the width is 4x+1

6. There are 785 students in the senior class. If there are 77 more females in
the class than males, how many male and female seniors are there?
... please solve this using if systems of equations
Answer:
there are 431 females and 354 males in the class
Step-by-step explanation:
Let the number of females student in the class be x
Let the males by y
If there are 785 students in the senior class, then;
x+y = 785 .... 1
If there are 77 more females in the class than males, then;
x = y+77 ....2
Substitute 2 into 1
y+77+y = 785
2y = 785 - 77
2y = 708
y = 708/2
y = 354
Since x = 785 - y
x = 785 - 354
x = 431
Hence there are 431 females and 354 males in the class
a number t divided by 17 equals the opposite of three
t/17=-3
---
I have no idea how to explain so...
hope it helps?
Answer:
Well the opposite of three (my guess) would be -3 so you multiply 17 by -3 and that is -51 (-51÷17=-3) so the number is -51
Step-by-step explanation:

Based on the problem above, how would you rewrite as a binomial squared?
x^2 + 8x - 3 = 0 (x + __ )^2 = __
Answer:
the quadratic equation cannot be written as the square of a binomial
Step-by-step explanation:
Given the expression
x^2 + 8x - 3 = 0
On factorizing
x = -8±√8²-4(-3)/2
x = -8±√64+12/2
x = -8±√76/2
x = -8±8.7/2
Note that since the since the discriminant is not a prefect square, the quadratic equation cannot be written as the square of a binomial
In a baseball card collection, 40% of the cards are worth more than 100$. If 12 cards in the collection are worth more than $100, how many total baseball cards are in the collection?
Answer:
30
Step-by-step explanation:
12 is 40% of the total number of cards.
12 = 0.4x, where x is total number of cards
/0.4 /0.4
30 = x
30 cards

Given (11,2) and (x,−4), find all x such that the distance between these two points is 10. Separate multiple answers with a comma.
Answer: x = 3, 19
Step-by-step explanation:
Given
Two points i.e. [tex](11,2)\ \text{and}\ (x,-4)[/tex] are given
Distance between them is 10 units
Distance is given by the distance formula
[tex]\Rightarrow d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance between two points is
[tex]\Rightarrow 10=\sqrt{(x-11)^2+(-4-2)^2}[/tex]
Squaring both sides
[tex]\Rightarrow 100=(x-11)^2+(-6)^2\\\Rightarrow 100=x^2+121-22x+36\\\Rightarrow x^2-22x+57=0\\\Rightarrow x^2-19x-3x+57=0\\\Rightarrow x(x-19)-3(x-19)=0\\\Rightarrow (x-19)(x-3)=0[/tex]
i.e. [tex]x\ \text{can be }\ x=3\ or\ 19[/tex]
ANSWER FAST ITS DUE IN AN HOURRRRRR
can anyone do this quickly?
Answer:
4th option (x = 60)
Step-by-step explanation:
This is isosceles triangle so the angles are the same. Think of this as an mirror. AE is the same as BE so you can assume angle ABE is 30 degrees.
30+30=60
180-60=120
So angle AEB is 120.
That is supplementary angle so the other side must be 180-120=60.
So, the middle smaller triangle is isosceles as well, so BED and BDE are both 60.
60+60=120, 180-120=60
So angle x = 60

A regular pentagon has sides of 10 cm. Find the radius of the largest circle which can
be drawn inside the pentagon.
Answer is 6.88 cm
Divide the pentagon radially into five congruent, isosceles triangles. Each triangle has a vertex angle of 360°÷5=72° and altitude of 5÷tan(36°).
radius of circle = 5÷tan(36°) = 6.88 cm

solve for x
x- 5/3=1
Answer:
x = 8/3 or 2 2/3
Step-by-step explanation:
x - 5/3 = 1
x - 5/3 + 5/3 = x
1 + 5/3 = 8/3 or 2 2/3
x = 8/3 or 2 2/3
Answer:
x = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
Given
x - [tex]\frac{5}{3}[/tex] = 1 ( multiply through by 3 to clear the fraction )
3x - 5 = 3 ( add 5 to both sides )
3x = 8 ( divide both sides by 3 )
x = [tex]\frac{8}{3}[/tex]

The ratio of girls to boys is 12 girls to 20 boys.
If there are 3 girls, how many boys are there?
There are
boys.
Next Question
Answer:
5
Step-by-step explanation:
ratio = 12:20
12/4 = 3
so we do
20/4 = 5
there are 5 boys
Another way, we can write it as a fraction
12/20 = 3/x
12x = 60
x = 5
Answer:
5 boys
Step-by-step explanation:
Write it like this:
3/X=12/20
Then, cross multiply.
3*20=60
X*12=12X
12X=60
Divide both sides by 12
60/12=5
X=5
The unknown number is 5
If there are 3 girls, then there are 5 boys.

Answer:
8x20+22
160+22
182.
48x4= 192 (closest to 182) since you can’t have a remainder of kids.
(I’m in 6th grade so I hope I helped and didn’t get it wrong)
So the answer is 4 or 5 busses.
