RM=3000

Answer:

The answer is x= -6

Step-by-step explanation:

3(x-8)=10x+18

3x-24=10x+18

3x-24=10x+18

Both side +24

3x=18+24+10x

Both side -10 x

3x-10x=42

-7x= 42

Both side divided by 7

x= -6

Answer:

330cm²

Step-by-step explanation:

CSA of a cylinder = 2πrh

(r = d/2 = 21/2 = 10.5 cm)

Putting the values of 2πrh;

2 x 22/7 x 10.5 x 5

2 x 22 x 1.5 x 5 *(10.5/7 = 1.5)

330 cm²

Answer:

x = 10

z = 116

Step-by-step explanation:

12x - 58 = 62

x = 10

360 - 128 = 232

232 / 2 = 116

Answer:

x = 10

z = 116

Step-by-step explanation:

Answer:8

Step-by-step explanation:

Truck:car

6:2 or simplified to 3:1, which means 3 trucks for every 1 car.

24 trucks divided by 3 gives you 8.

Answer:

8 cars

Step-by-step explanation:

Set up a proportion to model this situation. First, write and simplify the given proportion.

trucks to cars;

6 : 2

Simplify,

3 : 1

Assuming that the rate at which trucks and cars are present in the parking lot is constant, one can make the expression,

trucks : cars

3 : 1 = 24 : x

Where (x) represents the unknown amount of cars. One can use cross products to solve this proportion,

3 : 1 = 24 : x

24 = 3x

Inverse operations,

24 = 3x

8 = x

Answer:

15x+25 ; 70

Step-by-step explanation:

Given that,

Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.

Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :

y = 15x+25

For 3 hours,

y = 15(3)+25

= 45 + 25

= 70

So, the required option is (c) " 15x+25 ; 70 ".

Answer:

theta = 210°

Step-by-step explanation:

To convert we radians to degrees all we have to do is multiply the radians by π/180:

radians * (180 / π) = degrees

((7π) / 6) * (180 / π) = 210°

Answer:

x = 10

Step-by-step explanation:

3x + 10 = 40

which X in this case means 10. Hope this helps!

Answer:

His collection increased in a 20%.

Step-by-step explanation:

If 100% represents 10 records, what percentage would be for 12 records?

x = 12 100% / 10 = 120%

So, if we subtract 120% - 100%, it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.

It was a debate between the northerners and southerners (forgive my spelling). The northerners feared the addition of more slave states and a corresponding lack of reprenestation of their intrests in the North. For the southern slave holders, new western lands would be a boon (helpful) to enslaved people and the Louisiana purchase threatened to entrench and expand their suffering to western territories.

Answer:

x > 49

Step-by-step explanation:

We have the inequality Square root of x is greater than 7, to solve. We need to isolate x.

When having a square root, you need to raise the square root to its second power, with that, do the same to 7 on the other sides :

(Square root of x)^2 > 7^2

x > 49

Answer:

b 28 and 62

Step-by-step explanation:

X is equal to 14 so other angle is 2x which is.2multiplied to X which gives 28degrees

X is equal to 14 and the other.angle is 3xplus 20 so 3x is 42 plus 20 gives 62

Step-by-step explanation:

The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.
