Divide 4 to both sides of the equation
Answer:
16 cm
Step-by-step explanation:
Answer:
1) 3(9) +15
2) 2(-5)^2 - 11
3) (-2)^3 + 13(-2)
4) 4(6)^2 -7
5) (-9)^2 - (-9) + 10
All you have to do solve
Step-by-step explanation:
Replace the x with whatever number is in the f(number)
Divide both sides by <span>t
</span>
<span>a+b=r/t
</span>Subtract b <span>from both sides
</span>
a<span>=r/t-b = Solution </span>
You have to make the denominators (bottom numbers) the same via multiplication, it's best to do it to the first number they meet at. that would be fifteen (15)
5×3=15
3×5=15
you then have to multiply the numerators by the respective numbers.
2×3=6
1×5=5
you then subtract the numerators normally
6-5=1
slap back on the denominator
1/15
there's your answer.
(the number you multiply them by isn't the other denominator, it just happens to be the denominators for this equation)
