Answer 2

Answer:

B. 4

Step-by-step explanation:

5x - 2(2x-1) = 6   Distribute first the 2 to (2x-1)

5x - 4x + 2 = 6    Subtract 5x - 4x

x + 2 = 6   Transpose 2 to the right side by subtracting both side by 2

x = 6 -2

x  = 4

there are 84 calories in 100g of banana there are 87 calories in 100g of yoghurt priti has 60 g of banana and 150g of yoghurt for breakfast work out the total number of calories in this breakfast ​

Answers

It’s 128 or 129 either or works tbh

Total calories intake of Priti is 180.9 calories

Given that;

Number of calories in 100g banana = 84 calories

Number of calories in 100g yoghurt = 87 calories

Amount of banana and yoghurt Priti have = 60g and 150g respective

Find:

Total calories intake of Priti

Computation:

Total calories intake of Priti = 60[84/100] + 150[87/100]

Total calories intake of Priti = 50.4 + 130.5

Total calories intake of Priti = 180.9 calories

14. What is the solution of the system?
5x - y= -7
3x - y= -2
-2.5, -5.5
-2.5, 11
5, 2.5
2.5, 5.5

Answers

Answer: -2.5,   -5.5

Step-by-step explanation:

5x - y= -7

3x - y= -2 multiply by -1

5x - y= -7

-3x + y= +2 we add both equations

2x=-7+2,  2x=-5,   x=5/2= -2.5

5(-2.5)-y=-7

- 12.5-y= -7 we simplify and get

-y=-7+12.5,             -y=5.5,    y=-5.5

U is between G and B. R is between G and U. if GR is 3x-2, RU is 5x+7 , UB is 12 and GB is 15x-11.

x is ____

GR is ____

GB is ____

please help! ​

Answers

Answer:

x is 4

GR is 10

GB is 49

Step-by-step explanation:

If U is between G and B, then GU + UB = GB .... 1

If R is between G and U, GR + RU = GU ....2

Given

GR is 3x-2

RU is 5x+7

UB is 12

GB is 15x-11

Substitute2 into 1;

Frim 1;

GU + UB = GB

(GR+RU) + UB = GB

3x-2+5x+7+12 = 15x-11

8x+17 = 15x-11

8x-15x = -11-17

-7x = -28

x = 28/7

x = 4

Get GR:

GR = 3x-2

GR = 3(4)-2

GR = 12-2

GR = 10

Get GB:

GB = 15x-11

GB = 15(4)-11

GB = 60-11

GB = 49

T=PV/K

Starting with V=KT/P, multiply P on both sides to get PV=KT

Then divide K on both sides to leave T alone

And you get.....T =PV/K

Answer:

The light blue/greenish one that says T=PV/K or Greeland

Step-by-step explanation:

We can make the equation more simplier by multiplying both sides by P to remove fractions.

It would become VP=KT

The only answer with VP or PV is B, or the T=PV/K

also, to isolate T, divide the VP=KT by K on both sides to isolate T.

VP/K=T

Answer:

b = 12

Step-by-step explanation:

a² + b² = c²

a and b are the length of the sides in the right triangle and c is the hypotenuse.

since we know one leg and the hypotenuse, we can find the other leg.

9² + b² = 15²

81 + b² = 225

b² = 225 - 81

b² = 144

b = 12

Answer:

The answer is 12

Step-by-step explanation:

the formula is A^2+B^2=c^2

9² + b² = 15²

81 + b² = 225

b² = 225 - 81

b² = 144

b = 12

If the probability of writing the correct answer to the question on an exam is 2/5, what are the odds against writing the correct answer?

Answers

Answer is  3:2

Explanation

The probability of getting the correct answer is 2/5. This means there are 2 events of getting it right out of 5 events total. Since there are 2 events of getting it right, there are 5-2 = 3 events of getting it wrong.

The odds against getting the right answer is 3:2. We list the number of ways to get it wrong first, a colon, then the number of ways of getting it right.
