Find the value of the trigonometric function to find an approximate value correct to give decimal places

11x + 12 = 8x - 9 ... please

Marat540 [252]

Assignment: $\bold{\Solve \ Equation: \ 11x+12=8x-9}$

<><><><><><><>

Answer: $\boxed{\bold{x=-7}}$

<><><><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><><><>

[ Step One ] Subtract 12 From Both Sides

$\bold{11x+12-12=8x-9-12}$

[ Step Two ] Simplify

$\bold{11x=8x-21}$

[ Step Three ] Subtract 8x From Both Sides

$\bold{11x-8x=8x-21-8x}$

[ Step Four ] Simplify

$\bold{3x=-21}$

[ Step Five ] Divide Both Sides By 3

$\bold{\frac{3x}{3}=\frac{-21}{3}}$

[ Step Six ] Simplify

$\bold{x=-7}$

Please guys help me with this question. I will give you the brainliest if you give me the correct answers.

Butoxors [25]

Answer:

(a) She is 280m from her starting position

(b) 200m west then 80m south

Step-by-step explanation:

(a) 80m + 200m

= 280m

(b) First she walked 80m north n 200 east

If she want to get back to her starting position she will have to travel the same distance in the opposite direction

Opposite of East is West n opposite north is south

so she will have to go 200m west n then 80m south

Line m is intersected by line t , as shown in the diagram below. Based on the diagram, which of the following equations must be

Anna11 [10]

the answer is quite simple on this one. angles 1 and 3 are equal, and angles 2 and 4 are equal.

if you thi k about moving line t then you can see 2 and 4 will not add to 90°. angles 2 and 3 do not add to 90° because their angles added make a straight line (180°). answer B is almost true but not quite since the angles are not perpendicular to each other (1 and 3).

therefore, answer is A because of said explanation about answer B in previous paragraph. they make a straight line (180°). just basic geometry.

2 is 10 times 0.02 tire of false

chubhunter [2.5K]

This is false because when you multiply a number by 10, you simply move the decimal place one to the right. In this case, when we multiply 0.02 by 10, we get .2. Had we multiplied 0.02 by 100, we would have gotten 2.

five note cards each contain a different single-digit numbers.The cards are arranged to find the largest possible 5-digit number

Mashutka [201]

Solution: The largest number is 86521, the smallest number is 12568 and the sum of digits is 22.

Explanation:

Let the digits on cards be a, b, c, d and e. where $a>b>c>d>e>0$ because if the smallest digit is 0, then we get a four digit number on rearrangement.

To get the five digit greatest number we have to arrange these digits in descending order. So the greatest number is abcde.

To get the five digit greatest number we have to arrange these digits in descending order. So the smallest number is edcba.

It is given that the sum of greatest and smallest number is 99089.

When we add greatest and smallest number we noticed that the sum of c and c is 2c which is equal to 0. It is possible if c=0 or c=5. since c>0, therefore the value of c=5.

So the from the addition of unit digits we get e+a=9, there are many possibilities to get the sum 9 like 1+8, 2+7 and 3+6 because a>5 and e<5 since we have to find the greatest and smallest number so by hidden trial the value of e=1 and a=8. Similarly d+b=8, b>5 and d<5 by hidden trial the value of b=2 and d=6.

The digits are 8, 6, 5, 2 and 1, therefore largest number is 86521, the smallest number is 12568 and the sum of digits is 22.
