Translate the statements into equations. We can use 'x' for dimes and 'y' for quarters.
"<span>A boy has 11 coins in dimes and quarters"
"</span><span>Their value is $1.70"
</span>
<span>
To solve this, we can first solve for one of the variables in the first equation, and then plug that into the second equation:
Subtract 'x' to both sides:
Now plug this value of 'y' into the second equation:
</span>
So this equation could be used to solve the problem.
To figure this out simply divide 22 by 2, 11, so therefore 11+11=22. subtract 3 from 11, add 3 to the other 11 because 3+3=6, making the correct answer 8+14=22.
Answer:
D. -4
Step-by-step explanation:
-5x+10y = 20
To find the x intercept set y = 0 and solve for x
-5x+0=20
-5x = 20
Divide by -5
-5x/-5 = 20/-5
x = -4
Answer:
=3. The remainder of given polynomial is 3.
Let us take polynomial f(x) as dividend and linear expression as divisor.
The linear expression should be in the form of x-a.
Then, the remainder value of polynomial will become f(a).
So, substitute the c value in the polynomial expression and evaluate to get the remainder value.
