Answer:
When dividing two fractions, the process is very easy. You simply multiply the numerator fraction by the reciprocal of the denominator fraction. In other words:
[tex]\frac{a}{b} \div \frac{c}{d} \\= \frac{a}{b} \times \frac{d}{c} \\= \frac{a \times d}{b \times c}[/tex]

Answer: (x-6)(x+1)
Step-by-step explanation:
Sum : x2 − 5 x- 6
x2 + x-=6 x − 6
factor pair: x 2 + x − 6 x − 6
x( x+ 1 ) − 6 ( x + 1 )
rewrite from: x (x + 1 ) − 6 ( x + 1 )
(x-6)(x+1)
Answer:
A: (x-6)(x+1)
Step-by-step explanation:
We need to find 2 numbers that add to make -5 and multiply to make -6.
We already have the numbers infront of us, so by process of elimination we can remove B and D.
For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.
If we expand A, it makes the expression that needs to be factorised because...
-6 × 1 = -6
-6 + 1 = -5
So expanding it properly we get.
x² - 6x + x - 6
Simplify.
x² - 5x -6
solve the equation -16(d+1) =-20
Answer:
d= 1/ 4
Step-by-step explanation:
Answer: 1/4
Step-by-step explanation:
-16(d + 1) = -20
-16d - 16 = -20
-16d - 16 + 16 = -20 + 16
-16d = -4
-16d/-16 = -4/-16
d = 1/4

Fahim is 6 feet tall. At noon, he stands with the sun behind him casting a shadow. The distance from the top of Fahim’s head to the furthest tip of the shadow is 13 feet.
A right triangle with side length 6 feet, s, and hypotenuse 13 feet.
[Not drawn to scale]
What is the length of Fahim’s shadow? Round to the nearest tenth of a foot.
7.0 feet
8.5 feet
11.5 feet
14.3 feet
Answer: 11.5 feet
Step-by-step explanation:
We should note that for a right angles triangle, the square of the hypothenuse equals to the square of the opposite side and its adjacent. This can be expressed as:
Let the length of Fahims shadow be x
hypotenuse² = opposite² + adjacent ²
13² = 6² + x²
169 = 36 + x²
x² = 169 - 36
x² = 133
x =✓133
x = 11.53
= 11.5 feet to nearest tenth

Answer:
ML = 6
Step-by-step explanation:
Since HIJ is a scale drawing of KML, this means the IJ and ML are corresponding sides. The corresponding sides have proportional lengths, so from HJ ≅ LK you can learn that the scale factor is 20 / 5 = 4. likewise you can confirm this with HI ≅ MK is 36 / 9 = 4.
So ML is found by dividing JI by 4 = 24/4 = 6.

Given the equation 25 + 7x = 11
x = -2
x = 2
X = -14
x = 14
Answer:
x = -2
Step-by-step explanation:
Isolate the variable (or x) by subtracting 25 from both sides.
We do this and get 7x = -14
Divide both sides by 7 and we get x = -2

8×15= 120
120÷24= 5
m=5
23.)9/p = 4/48
9×48= 432
432÷4=108
p=108
24.) 10.50÷3= 3.50
thats $3.50 per pizza.
9 pizzas= $31.50
plus one pizza aka, 31.50+3.50= $35
therefore, 10 pizzas would cost $35
26.) 5/2 = d-2/4
cross multiply:
5×4=2(d-2)
20= 2(d-2) divide both sides by 2
20÷2 = 2(d-2)÷2
10= d-2 exchange places with d and 10 and change signs
-d= -2-10
-d=-12 change the sign on both sides when the variable is negative.
d=12
PLEASE I REALLY NEED YOUR HELP!
Answer:
x = 28
m∠ACD = 68°
Step-by-step explanation:
∠BAE ≅∠DAC because they are vertical angles
∠ACD = 180 - 124 = 56°
to find 'x': 56 + 2x + (180 - 4x) = 180
236 - 2x = 180
-2x = -56
x = 28
m∠ACD = 180 - 4(28) = 180 - 112 = 68°

Answer:
The answer to the question is 540°
Step-by-step explanation:
The reason to the answer is:-
There is a formula which is (n - 2) × 180
n is the number of sides the shape has, and there is 5 sides so we subtract 5 - 2 = 3
Therefore, 3 × 180 = 540°

If 500 calories adds 1 pound to your weight how many 1000 calorie banana splits would you need to eat to gain 10 pounds
Answer: 5
Step-by-step explanation:
each banana split is equal to 2 lbs. therefore, to gain 10 lbs. you need to eat 5 banana splits.
500cal = 1 lb.
1000cal = 1 banana split
1 banana split = 2lbs.
to gain 10lbs, divide 10lbs by 2lbs = 5 banana splits

An expression is shown below. Which expression is equivalent to the expression shown?
- 2x(x + y - 3) + 3(-x + 4y) + y(3x + 5y - 3)
- 2x2(5y2 + xy + 3x + 9y
- 2x2 + 5y2 + xy - 6x +9y
- 5x2 + 5y2 + xy + 3x + 9y
- 5x2 + 5y2 + xy - 6x + 9y
Note: In option A, it should be "+" instead of "(".
Given:
The expression is
[tex]-2x(x+y-3)+3(-x+4y)+y(3x+5y-3)[/tex]
To find:
The equivalent expression.
Solution:
We have,
[tex]-2x(x+y-3)+3(-x+4y)+y(3x+5y-3)[/tex]
Using distributive property, we get
[tex]=-2x(x)-2x(y)-2x(-3)+3(-x)+3(4y)+y(3x)+y(5y)+y(-3)[/tex]
[tex]=-2x^2-2xy+6x-3x+12y+3xy+5y^2-3y[/tex]
On combining like terms, we get
[tex]=-2x^2+5y^2+(-2xy+3xy)+(6x-3x)+(12y-3y)[/tex]
[tex]=-2x^2+5y^2+xy+3x+9y[/tex]
The expression [tex]-2x^2+5y^2+xy+3x+9y[/tex] is equivalent to the given expression.
Therefore, the correct option is A.
