The sum of two numbers is 8, and their difference is 22
lawyer [7]

Answer:

15, -7 x=15 y=-7

Step-by-step explanation:

x+y=8, we'll come back to this

x-y=22, move y to the other side, x=y+22

now insert the value of x =(y+22) to the other equation like so, (y+22)+y=8, simplify

2y+22=8 2y=(-14), y=(-7)

Insert the value of y into the first equation again like so, x+(-7)=8, simplify

x=15

15, -7

6 sweets cost 42p altogether how much do 8 sweets cost?
Inessa05 [86]
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
Hope this helps :)

Answer

Roundworm is 9ft long and the tapeworm is 60 feet long

Step-by-step explanation:

If we turn this into an algebraic equation we get 8x-3=69 with 8x being x + 7x because we know that the tape worm is about 7 times longer than the round worm and the roundworms length would be x here. We have the -3 because it is 3 minus 7 times the total length. We do this and eventually end up with x = 9 which is the length of the roundworm. We multiply that by 7 to get 63 and subtract 3 to get 60. If you want to check if this is right do 60+9 and you'll get 69 which is the total of them end to end. (also 69 funny haha)

Can some one please help me with this math question? Please and thank you

Answer:

V = 6373.2cm^3

Step-by-step explanation:

Given

V = \frac{4}{3}\pi r^3 --- Volume

D = 23cm --- Diameter

Required

Find the volume

First, we calculate the radius, r

r = \frac{1}{2}D

Substitute 23 for D

r = \frac{1}{2} * 23

r = 11.5

Substitute 11.5 for r in V = \frac{4}{3}\pi r^3

V = \frac{4}{3} * \frac{22}{7} * 11.5^3

V = \frac{4*22*11.5^3}{3*7}

V = \frac{133837}{21}

V = 6373.19047619

V = 6373.2cm^3
