when you multiply a number by 5 and then by 2, it is the same as multiplying by 10. Multiplying by by 10 means you add a zero to the end of the number so the digit in the ones column will always be zero

Gnom [1K]

Answer:

$x=38.5^\circ$

Step-by-step explanation:

Given that the left angle = $(3x-3)^\circ$

The right angle across from it $= 6(x-10)^\circ$

The other two angles are x and x.

We know that the sum of angles at a point equals 360 degrees.

Therefore,

$(3x-3)^\circ+6(x-10)^\circ+x+x=360^\circ\\3x-3+6x-60+2x=360\\11x-63=360\\11x=360+63\\11x=423\\x=38.5^\circ$

The value of x is approximately 38.5 degrees.

Lance and Alex have 70 pencils. Lance has 4 times as many pencils as Alex. Alex's pencils are shared equally among 2 children. H

gogolik [260]

let l = lance, and a = alex.

so: l + a = 70

and l = 4a

Putting the value for l in the first equation:

4a +a = 70

5a = 70

a = 14.

So Alex has 14 pencils. And Lance has (70-14) 56 pencils.

And if each child gets half of Alex' pencils, then each child will have 7 pencils.
