Find the value of x, y and z

Mathematics
1 answer:
tangare [24]3 years ago
7 0

Answer:

Step-by-step explanation:

8x = 9x - 7

-x = -7

x = 7

9(7)-7= 63-7=56

8(7)= 56

13y+7+56=180

13y+63=180

13y=117

y=9

13(9)+7= 117+7= 124

5y-11+56=90

5y+45=90

5y=45

y=9

5(9)-11+9(7)-7= z

45-11+63-7=z

34+56=z

90=z

Question 78 find the value of x
gladu [14]

For this case we have that by definition, the volume of a parallelepiped is given by:

V = l * w * h

Where:

l: It's the long

w: It is the width

h: It's the height

From the figure we have the following data:

V = 975 \ ft ^ 3\\h = 9 \ ft\\w = 4ft\\x =?

We must find the value of the length of the parallelepiped:

975 = x * 4 * 9\\975 = 36x\\x = \frac {975} {36}\\x = 27.083

Answer:

x = 27.1 \ ft

I need help FAST!!!!
Pavel [41]

Answer:

Step-by-step explanation:

okay, so here are a few methods you can use.

___

1) +

x + 7 = 10 so because this is addition we use the reverse, subtraction. So

x - 7 = 10 - 7 and that equals to 3.

2) -

x - 2 = 10 so because this is subtraction we do the reverse, addition.

x + 2 = 10 + 2 and that equals to 12.

3) x

x times 3 = 21 because this is multiplying we divide.

x/3 = 21/3 and that would be 7.

4) /

x/2 = 10 same as above, reverse is multiplying.

x times 2 = 10 times 2 and thats 20.
