Translating that problem with x being our variable you get 3x + 5x-11 = 15. Combine like terms to get 8x-11 = 15. Add 11 to both sides to get 8x = 26. Divide by 8 on both sides to get x = 26/8. This can be reduced to 13/4 or 3 and 1/4. 

Now we plug in. Our first number was represented by 3x. So 3*(13/4) = 39/4 or 9 and 3/4. The second number was represented by 5x-11. 5*(13/4) = 65/4 or 16 and 1/4. 16 and 1/4 minus 11 is 5 and 1/4.

To check our answer 9 + 5 = 14. 3/4 + 1/4 = 4/4 or 1. 14+1 = 15. Another way to check is adding (39+21)/4.

So your complete sentence should read: The two numbers whose sum equal 15 in this equation are 5 and 1/4 (or 21/4) and 9 and 3/4 (or 39/4).

What is the measure of EAB in circle F?<br> 72°<br> 92°<br> 148°<br> 200°
Arada [10]

We have been given a diagram. We are asked find the measure of arc EAB.

First of all, we will find the measure of arcs ED and CB using our given information.

We know that measure of an inscribed angle is half the measure of intercepted arc.

We can see that angle EBC is inscribed angle of arc EDC, so measure of arc EDC will be twice the measure of angle EBC.

\widehat{EDC}=2\times m\angle EBC

\widehat{EDC}=2\times 80^{\circ}

\widehat{EDC}=160^{\circ}

Similarly, we will find the measure of arc DCB.

\widehat{DCB}=2\times m\angle DEB

\widehat{DCB}=2\times 70^{\circ}

\widehat{DCB}=140^{\circ}

\widehat{ED}=\widehat{EDC}-\wdiehat{DC}

\widehat{ED}=160^{\circ}-88^{\circ}

\widehat{ED}=72^{\circ}

\widehat{ED}+\widehat{DCB}+\widehat{EAB}=360^{\circ}

72^{\circ}+140^{\circ}+\widehat{EAB}=360^{\circ}

212^{\circ}+\widehat{EAB}=360^{\circ}

\widehat{EAB}=360^{\circ}-212^{\circ}

\widehat{EAB}=148^{\circ}

Therefore, the measure of arc EAB is 148 degrees and option C is the correct choice.

The first digit may be 1 or 8.

The second digit may be 1, 2, 4, 8.

The third digit may be 1, 3, 5, 7, 9.

There are 2\times4\times5=40\:variants

The probability that this is the correct code is \frac{1}{40}
