<span>Let x=one number and x+12= the other number.  Together the numbers=54.  Set up the equation:  x+x+12=54;  Combine the variables;  2x+12=54;  Subtract 12 from both sides of the equation;  2x=42; Divide both sides of the equation by 2;  x=21 is one number and 21+12=33 is the other number.  Check:  2(21) +12=54;  42+12=54;  54=54.</span>

Step-by-step explanation:

A=2πrh+2π {r}^{2}

= 2\pi.r(r + h)

= 2π(14).(14+29)

=2π .14.43

2 \times  \frac{22}{7}  \times 14 \times 43

= 2 \times 22 \times 2 \times 43

(100 points) HELP ME NOW!!!! NOOOOW!!!!! OR ELSE UR GONNA BE SUPER DUPER SORRY &gt;:)
Zielflug [23.3K]

Answer:

The answer is in the image! The interval notation is [-5,4)

Step-by-step explanation:

Notice that on the linee graph it shows a open circle on 4 and a closed dot on -5... This is because the number can be greater than -5 or equal to(this is represented by the brackets) and on 4 it can only be less than 4 and not equal to it (Represented by parenthesis)...

To solve for the inequality you must solve for x. The easiest way to do this is to multiply each component in the middlee by 3, the add two on both sides, then divide by 9 on both sides. This gives you the simplest inequality at -5<= x <4!

Hope this helps! If you cant open the image let me know!

A garden table and a bench cost $688 combined. The garden table costs $62 less than the bench. What is the cost of the bench?
Savatey [412]
If the bench costs  x dollars we have the equation 
x + x - 62 = 688
2x = 750 
x = $375

The bench cost $375
