Answer:
Area=1/2bh
Given area of 36m^2
1/2(x)(x-1)=36
Multiply both sides by 2 to remove deminator
(x)(x-1)=72
X^2-x=72
X^2-x-72=0 then factor
(x-9)(x+8)=0
X=9,-8 however since area must be positive, take the absolute value of 8
1/2(9m*8m)=36m^2
Find the value of x... Please look at the attachment below

Jenny measured 1/7 cup of flour and 1/3 cup of flour. How many total cups of flour did Jenny measure?
Answer:
I think it 25/36.
Step-by-step explanation:
The total amount of flour is 4/9 + 1/4. The common denominator of 9 and 4 is 36.
So 4/9 + 1/4 = 16/36 + 9/36 = 25/36
Jenny measured a total of 10/21 cups of flour.
Given that,
Jenny measured 1/7 cup of flour and 1/3 cup of flour. How many total cups of flour did Jenny measure is to be determined.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Fraction is defined as the number of compositions that constitute the Whole. The fraction can be represented in the form of a / b.
Here,
Let, the total measure of the cups of flour be x,
x = 1/7 + 1/3
Taking lcm of the denominator 7, 3 which is 21,
now multiplying the numerators by 3 and 7,
x = (3*1 + 1*7)/21
x = 10 / 21
Thus, Jenny measured a total of 10/21 cups of flour.

-5x+3y=15 and 2x-3y= -15
Answer:
x = 0; y = 5
Step-by-step explanation:
-5x + 3y = 15
2x - 3y = -15
Add the equations to eliminate y.
3x = 0
x = 0
Now plug in 0 for x in the first equation to solve for y.
-5(0) + 3y = 15
3y = 15
y = 5
Answer: x = 0; y = 5

What is the equation?
Answer:
y - 4 = (1/3)(x - 9) or x - 3y = -3
Step-by-step explanation:
Here we're told that the slope is 1/3 and that (9, 4) is a point on the line. Use the point-slope formula y - k = m(x - h). Substitute 4 for k, 9 for h and 1/3 for m:
y - 4 = (1/3)(x - 9) (point-slope formula)
3y - 12 = x - 9 (standard form of the same equation) = >
-12 + 9 = x - 3y, or x - 3y = -3 (standard form)
Sue's bakery sold 850 donuts last week. This week, the number of donuts sold increased 12%. HOW MANY MORE donuts were sold this week as compared to last week
Answer:
102 donuts
Step-by-step explanation:

The volume of a cube is 216 ft^3. What is the length of a side?
Answer:
54
Step-by-step explanation:
cause a cub has 4 sides so each side is 54
Answer:
The length of a side is 6.
Step-by-step explanation:
Since, the volume of a cube is equal to l*w*h.
V=l*w*h
Volume is equal to side cubed.
V=s^3
Cube 216 to get 6.
216=s^3
3^√216=s
Answer: 6

Simplify and write the trigonometric expression in terms of sine and cosine: sec t − cos t sec t = ( f ( t ) ) 2 sect-costsect=(f(t))2
Answer:
[tex]f(t) = 1 - cos^2\ t[/tex] and [tex]f(t) = sin^2\ t[/tex]
Step-by-step explanation:
Given
[tex]\frac{sec\ t - cos\ t}{sec\ t} = f(t)[/tex]
Required
Simplify
[tex]f(t) = \frac{sec\ t - cos\ t}{sec\ t}[/tex]
Split fraction
[tex]f(t) = \frac{sec\ t }{sec\ t} - \frac{cos\ t}{sec\ t}[/tex]
[tex]f(t) = 1 - \frac{cos\ t}{sec\ t}[/tex]
[tex]sec\ t = \frac{1}{cos\ t}[/tex]
So, we have:
[tex]f(t) = 1 - \frac{cos\ t}{\frac{1}{cos\ t}}[/tex]
[tex]f(t) = 1 - cos\ t * cos\ t[/tex]
[tex]f(t) = 1 - cos^2\ t[/tex]
In trigonometry:
[tex]1 - cos^2\ t = sin^2\ t[/tex]
So, we have:
[tex]f(t) = sin^2\ t[/tex]
Some emoji math, there are more to be solve as well. 15 points for each. Must explain how to get the answers you got.
Answer:
Ladybug=7
clock= 5
bulb= 2
Step-by-step explanation:
there are a whole row of ladybugs that equal 21. 21/3=7.
on the third row, the value we need is 12, 6 won't work because we also have a bulb. so pug in 5, 5+5=10, that means the bulb is 2.
So now that we know the values, lets plug them into the first problem to see if it gives us 14... it does
So we have the correct answers
Also, you can plug in the values for the the bottom numbers and you will get those values

Use the linear combination method to solve the system of equations. Explain each step of your solution.
2x-3y=13
2x+4y=-8
Step-by-step explanation:
Equation 1: 2x - 3y = 13
Equation 2: 2x + 4y = -8
Subtract Equation 1 from Equation 2:
2x + 4y = -8
- (2x - 3y = 13)
=> 7y = -21, y = -3.
Then 2x - 3(-3) = 13, 2x + 9 = 13, x = 2.
The solutions are x = 2 and y = -3.

Answer:
its 8
Step-by-step explanation:

then divide your answer by 2 after that.
Equation A: y = 6x - 1
Equation B: y = 8x - 3
What is the solution (
,
) to the given set of equations?
Answer:
comparing both the equation,
3X-3=6x-1
or, -2 =3X
or, X= -2/3
Y=6X-1
or, Y= 6× -2/3 -1
or, Y= -4-1
or, Y= -5
hence the required solution is (-2/3, -5)
