60(2)+x(2)=260
120+2x=260
2x=140
x=70
its been a while since ive done inequalities so im sry if what i show isnt what you have
Answer:
he placed a * sign instead of an add sign in the second part of the equation
Step-by-step explanation:
6(2b+5)=6*2b + 6*5 = 12b + 30
Answer:
5
Step-by-step explanation:
If two is subtracted from a number: let's give the number a name and call it X . And this difference is tripled: so we get 3(X−2) . The result is 4 more than the number, so
3(X−2)=4+X .
We want to know X so we need to get it to one side of the equation. That's done by repeatedly doing the same operation on both sides of the equation. First get rid of the parentheses:
3X−6=4+X.
Now subtract X and add 6 :
2X=10
Divide by 2:
X=5
Let n = .234....
Now our job is to get the entire part that repeats on the left of the decimal point.
If we multiply the number by 1000 exactly one 2, one 3 and one 4 will move to the left.
So 1000n = 234.234... now lets remove our original number
-<u> n = -.234...</u> Notice how all the repeaters minus all the repeaters
999n = 234 leaves only the 234 that we move to the left of
the decimal point
Now lets divide both side by 999
<u>999n </u> = <u>234
</u>999 999 this is the answer in unreduced form 9 can go into both = <u>26</u><u>
</u> 111

Try it on your calculator (divide 26 by 111)
