Answer:

x = 20

y = 28

Step-by-step explanation:

hari's age: x

harry's age: y

7x = 5y

4(x+4) = 3(y+4)

4x+16 = 3y+12

4x+4 = 3y

5/3(4x+4) = 5y = 7x

20/3x +20/3 = 7x

20/3 = 1/3x

x = 20

y = 28

Answer:

Step-by-step explanation:

If you are doing probability with replacement they will all be 1/6 each time.

total there is 6/6. If you draw a yellow card first it's 1/6 then replace it and draw a blue it is still 1/6. so you take those two probabilities and multiply them (1/6)*(1/6)=1/36 1*1=1 and 6*6=36.

Your answer is 1/36

You are adding by 5 in the sequence.
If f(1) is -7
f(2) = -2
f(3)= 3
f(4)=8
f(5)=13
f(6)=18
Therefore, f(7)=23

If h(x) = −2x − 10, find h(−4). −2 −18 −3 −16
Anuta_ua [19.1K]
If h(x) = -2x - 10 you should put the -4, -2. -18, -3 or/and -16 in the place of the x in the formula.
So for example:

h(-4) = -2 * (-4) - 10 = 8 - 10 = -2

Or at least, that's what I think the answer should be.

Good luck!
