10(10x−12)=−9(−9x−2)−5
Step 1: Simplify both sides of the equation.
−10(10x−12)=−9(−9x−2)−5
(−10)(10x)+(−10)(−12)=(−9)(−9x)+(−9)(−2)+−5(Distribute)
−100x+120=81x+18+−5
−100x+120=(81x)+(18+−5)(Combine Like Terms)
−100x+120=81x+13
−100x+120=81x+13
Step 2: Subtract 81x from both sides.
−100x+120−81x=81x+13−81x
−181x+120=13
Step 3: Subtract 120 from both sides.
−181x+120−120=13−120
−181x=−107
Step 4: Divide both sides by -181.

Let's solve your equation step-by-step:

−10(10x − 12) = −9(−9x−2) − 5

Step 1: Simplify both sides of the equation:

−10(10x − 12) = −9(−9x−2) − 5

(−10)(10x) + (−10)(−12) = (−9)(−9x) + (−9)(−2) + −5 (Distribute):

−100x + 120 = 81x + 18 + −5

−100x + 120 = (81x) + (18 + −5) (Combine Like Terms):

−100x + 120 = 81x + 13

−100x + 120 = 81x + 13


Step 2: Subtract 81x from both sides.

−100x + 120 −81x = 81x + 13 − 81x

−181x + 120 = 13

Step 3: Subtract 120 from both sides.

−181x + 120 − 120 = 13 − 120

−181x = −107

Step 4: Divide both sides by -181.

−181x / - 181 = -107 / -181

x = 107 / 181 (Decimal: x = 0.59116....)

Answer: ===========> x = 107 / 181






Hope that helps!!!! : )

Find the x intercept and the y intercept of the graph of the equation <br> 2x+4y=8
maksim [4K]

Answer:

x-intercept: 4

y-intercept: 2

Step-by-step explanation:

finding the x-intercept:

first, substitute y = 0.

2x + 4 x 0 = 8

then, remove the 0.

2x + 0 = 8

then, divide both sides. 2x = 8

so, x = 4.

finding the y-intercept:

first, substitute x = 0.

then, solve.

2 x 0 + 4y = 8

so, y = 2.

Jelly ate 3 apples. This represents 50% of the bag of apples. How many apples were originally in the bag
rjkz [21]
<h3>Answer:  6 apples</h3>

x = number of apples originally

50% of x = 0.50*x = amount of apples eaten = 3

0.50x = 3

x = 3/0.50 ....... divide both sides by 0.50

x = 6

You can think of 50% as 1/2. If 3 apples represent half the bag, then the full bag is 6 apples. So half of 6 is 3.

If one root of the equation is 4x^2- 2x+p-4 be the reciprocal of other. then find the value of p​
SashulF [63]

Answer:

p = 8

Step-by-step explanation:

Let one root of the eqn. be alpha . Other root is 1/alpha .

We know that product of both roots of an quadratic eqn. is c/a where "c" is the co-efficient of the constant  & "a" is the co-efficient of x^2.

Here "c" is p-4 & "a" is 4. And the product of roots is 1 ( ∵ prdouct of a number and its reciprocal is 1 )

\frac{c}{a} = 1\\=> \frac{p - 4}{4} = 1\\=> p - 4 = 4\\=> p = 4 + 4 = 8
