Solve for z. 27/90=15/z

Mathematics
1 answer:
suter [353]3 years ago
3 0

Answer:

z= 50

Step-by-step explanation:

The equation 27/90=15/z can be written as the following if we simplify a little:

3/10=15/z.

remember 27=3*9 and 90=9*10, hence 27/90=3/10

Now lets multiply both sides by variable 'z'.

we have 3/10 * z= 15/z * z

3/10 z=15

Now lets multiply  by 10/3

3/10 * z * 10/3 = 15*10/3

z= 50

Number of Gallons 2 4 x
Travka [436]

Answer:

The value of x is 8 gallon.

Step-by-step explanation:

Given a table  showing approximate conversion from gallons to liters.

Number of Gallons    2      4      x

Number of Liters      7.6  15.2  30.4

We are required to find value of x,

Given : 2 gallon is equal to 7.6 liters.

⇒  1 liter is equal to \frac{2}{7.6}=0.263 liters. ........(1)

given, x gallon equal to 30.4 liters.

⇒ 1 liter is equal to \frac{x}{30.4} liters.  .........(2)

from (1) and (2),

⇒  0.263=\frac{x}{30.4}

Solving for x, we get,

⇒  0.263 \times 30.4=x

⇒  7.9952=x

Approximately x = 8

Thus, the value of x is 8 gallon.

Can someone help me find the equation for this line please
pogonyaev

Answer:

y = x + 1

Step-by-step explanation:

The line y = x  goes through the origin, and forms a perfect 45 degree angle with the x axis.

This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.

Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so

y = 1x + 1 = x + 1

y = x + 1
