$x+31$ and $2x-59$ are congruent sides

So we have
$2x-59=x+31$
⇒ $x-59=31$
⇒ $x=90$

Plug in:
$x+31=90+31=121$
$2x-59=2(90)-59=180-59=121$
$x-7=90-7=83$

Answer:

x= 25/3 or 8.333333

Step-by-step explanation:

you add 11 to 10 to get 21

3x-4=21

add 4 to both sides, which will cancel out the (-4)

3x=25

divide each term by 3 to get x by itself

3x/3 = 25/3

you will then get x=25/3

Rashan buys 3 7/10 pounds of flour and Diego buys 2 3/4 pounds of flour they use 4 3/5 pounds of flour to bake bread. how much f

Alex787 [66]

To make this a bit easier we can convert the fractions to decimals, then add them up to find out how much flour they originally had. Rashan bought 3 7/10 pounds of flour, which becomes 3.7 pounds. Diego bought 2 3/4 pounds of flour, which becomes 2.75 pounds of flour. In total they both had 3.7 + 2.75 = 6.45 pounds of flour.

Now they used 4 3/5 pounds to bake some bread, which becomes 4.6 pounds. To find out how much flour they have left, we subtract the 4.6 from 6.45, which equals 1.85 pounds of flour left.
