Answer:
plz make it brainlisted
Step-by-step explanation:
Since the total is 300 and the ratio is 4:1,
Let us suppose the number of adults be 4x and children be x;
According to the question,
4x+x=300
or,5x=300
or,x=(300/5)
or,x=60
So, 60 students attended the show.
You can multiply each fraction on both top and bottom so that they have 24 as the denominator. The equation becomes
![\frac{20}{24} m- \frac{10}{24} = \frac{21}{24} m+ \frac{16}{24}](https://tex.z-dn.net/?f=%20%5Cfrac%7B20%7D%7B24%7D%20m-%20%5Cfrac%7B10%7D%7B24%7D%20%3D%20%5Cfrac%7B21%7D%7B24%7D%20m%2B%20%5Cfrac%7B16%7D%7B24%7D%20)
subtract 16/24 to both sides and you get
![\frac{20}{24} m- \frac{26}{24} = \frac{21}{24} m](https://tex.z-dn.net/?f=%20%5Cfrac%7B20%7D%7B24%7D%20m-%20%5Cfrac%7B26%7D%7B24%7D%20%3D%20%5Cfrac%7B21%7D%7B24%7D%20m%20)
now subtract 20/24 from both sides and
![\frac{-26}{24} = \frac{21}{24} m](https://tex.z-dn.net/?f=%20%5Cfrac%7B-26%7D%7B24%7D%20%3D%20%5Cfrac%7B21%7D%7B24%7D%20m)
<u />
multiply 24 on both sides
-26=21m
and divide by 21 on both sides
m=-26/21 or -1.24
Answer:
See attached graph.
Step-by-step explanation:
We can graph this with relative ease on the calculator or computer (see attachment) but let's make sure we understand it theoretically and algebraically!
y=|x - 4| + 2
First of all, this is an absolute value function, so it'll look like a v where every input equals its positive output (2, 2) (-3,3) etc. You can't get a negative number with a graph of y=|x| unless you translate it.
Next, there's a -4 inside the abs val. According to the formula y = |x - h| + k, where h is the horizontal shift, this means we need to shift the vertex right 4.
There's a +2 outside the abs val. K is the vertical shift, so we need to shift the vertex up 2.
Answer:
£7
Step-by-step explanation:
x - .2x = £5.60
.8(x) = £5.6
x= £5.6/.8
