Answer:

46 1/5 inches tall

Step-by-step explanation:

We know each board is 2 1/5 inches high

Change this to an improper fraction

2 1/5 = (5*2+1)/5 = 11/5

Multiply this by the number of boards

11/5 * 21 = 231/5

Change this back to a mixed number

5 goes into 231 46 times

46*5 = 230  there is 1 left over

46 1/5 inches tall

4x-5y=39 y=6x-13<br>how would you solve it and what system of equation is it
yawa3891 [41]
Hi there,

4x - 5y = 39
y = 6x - 13

4x - 5(6x - 13) = 39
4x - 30x + 65 = 39
-26x = 39-65
-26x = -26
x= -26/-26
x= 1

So we deduce y now :

y = 6 *1 - 13
y= 6 - 13 = -7

Hope this helps !
