Answer:

I think it should be A.

Step-by-step explanation:

The first arrow represents 2, and the second arrow represents subtracting -3 from it, represented as -(-3). This means that the first part of the equation is 2 - (-3). Now you have to solve it. When subtraction is modeled like this with a negative number, it actually means addition. This means that the answer should be as simple as 2+3 because there were two negative signs. 2+3=5, so A should be the answer.

Answer:

Step-by-step explanation:

Because the arrow is going 2 in the right direction...so you have to have the 2 in the equation...

and the reason it equals 5 instead of a (-) number is because of the KCC rule

so basically the equation is 2+3

or if you don't want the long way just look at all of the equations...only one of the have a 2 in it so it is automatically the correct answer

Planet X has a mass of 8.46 x 1022 kg. Planet Y has a mass of 5,028,000,000,000,000,000,000,000 kilograms. How many times the ma

kramer

Answer:

59.4 times greater to the nearest tenth.

Step-by-step explanation:

5,028,000,000,000,000,000,000,000

= 5.028 * 10^24

So the required ratio = 5.028 * 10^24 / 8.46 * 10^22

= 0.594326 * 10^2

= 5.94326 * 10

= 59.4326.

zmey [24]

Simon has $45.37

Simone savings from allowance= $15.45

Amount Simone had in piggy bank = $7.37

Left over from birthday = $22.55

Total amount of money that Simone now has = $15.45 + $7.37 + $22.55

Total amount of money that Simone now has = $45.37

Solve a) 2(x+3)=x-4 b) 4(5x-2)=2(9x+3)

Nat2105 [25]

Answer:

a) -10 b) 7

Step-by-step explanation:

a) 2(x+ 3) = x - 4

2x + 6 = x - 4

2x - x = -6 - 4

x = -10

b) 4(5x - 2) = 2(9x + 3)

20x - 8 = 18x + 6

20x - 18x = 6 + 8

2x = 14

x = 14/2

x = 7

Help pls reallyyyyyyyyyyyyyyyyyy

Ivan

Answer:

Step-by-step explanation:

j=6

k=4

Rewrite the equation. So let's do that-

2.5(6*4)/6

6 and the other 6 cancel out so we are left with 2.5*4

Which is then equal to 10.

By the way, whenever you see the same number in a division problem on the numerator and denominator, just cancel them out because if you still did 2.5(6*4)/6, you would still get 10. I was just simplifying it!

Determine the value of x

Mekhanik [1.2K]

Answer:

2√2

Step-by-step explanation:

By using trigonometry,

sin 45° = x/4

x = 4sin 45°

x = 2√2

By using Pythagorean theorem,

Since you know that it is an isosceles triangle and it's also a right-angled triangle,

4² = x² + x²

16 = 2x²

x² = 8

x = √8

= 2√2
