3+4=7
7×4=28
28-6=22
hope this helps you
To get the answer we have to substitute x=3 and add 6 to the result.
Lets do this
f(x)=7-2x
f(3)=7-2*3=7-6=1
f(3)+6=1+6=7 - its the result

- Simplify ⇨ 9 + 5 (4x - 4)


Use the distributive property to multiply 5 by 4x-4.

Subtract 20 from 9 to get -11.

Putting it in standard form...(positive number in the 1st)

Answer:
B ( 3.7 , -1.1)
Step-by-step explanation:
<h3>
Given</h3><h3>
x + y = 2.6.......equation 1</h3>
y = 3x - 12.2.......equation 2
Putting equation 2 I. equation 1
x + 3x - 12.2 = 2.6
4x = 2.6 + 12.2
4x = 14.8
Therefore x = 3.7
Now
y = 3 * 3.7 - 12.2
= 11.1 - 12.2
= -1.1
27.2 is 68 percent of 40
to find this answer I divided 27.2 by 68 to find out how much 1 percent was; 1%=0.4then i just multiplied 0.4 by 100 to find out how much 100% was, and my answer was 40
hope this helps
