Answer:
16.) 35%
17.) 56%
18.) 5%
Step-by-step explanation:
Look at the denominator. How many times does it go into 100? For example, for the first one, 20 goes 5 times into 100. So I would multiply 7 and 5, and I would get 35.
You need to multiply the number (x) by 4 then add 3
<span> x/2 - 3 = 7
Add 3 to both sides
x/2=10
Multiply 2 on both sides
Final Answer: B. 20</span>
Answer:
2/3
Step-by-step explanation:
After adding 4x you will get 10= 6x+6. Next, you subtract 6 on both sides which will leave you with. 4=6x you then divide the 6 to the 4. You can also reduce which will give you the answer 2/3.
I hope this helps you
x.x+x.b+x.a+a.b
x^2+(b+a).x+a.b
a.b=8
a=1 b=8
a+b=k
k=1+8=9
a=2 b=4
k=2+4=6
a= -1 b= -8
k= -1-8=-9
a= -2 b= -4
k= -2-4=-6
