Answer:
y>5-x
Step-by-step explanation:
To solve this problem we need start by grouping terms in the same side of inequality.
Lets begging by grouping 'y' terms on the left side of inequality sign, to do this, subtract 3y to both sides:
2x+5y-3y>3y-3y+10
2x+2y>10
Now lets subtract 2x to both sides of inequality.
2x-2x+2y>10-2x
2y>10-2x
Now isolate variable x by dividing the inequaiity by 2.
y>5-x
That is the solution
<span>4x+2(3x-9)=42
first we want to distribute the 2 using the distributive property
4x+6x-18=42
Then we simplify
</span><span>10x-18=42
we add 18 to both sides
10x=60
divide both side by 10
x=6</span>
Answer:
I would say A. 7.8 x 10^-5
Step-by-step explanation:
7.8 x 10^-5 can also be written as 7.8 times 10 to the negative fifth power or the exponent of negative five. But, if you solve it you would get 0.000078 as the real number.
