Answer 1

Answer: $56+4=60\n\n60*3=180\n\n180:2=\fbox{90}\n\nCHECK:\n(2)/(3)*90-4=2*30-4=60-4=56$

=================================================

$128-38=90\n\n90*9=810\n\n810:5=\fbox{162}\n\nCHECK:\n\n38+(5)/(9)*162=38+5*18=38+90=128$

=================================================

$14.6-2.3=12.3\n\n12.3*5=61.5\n\n61.5:3=\fbox{20.5}\n\nCHECK:\n\n(3)/(5)*20.5+2.3=3*4.1+2.3=12.3+2.3=14.6$

Answer 2

Answer: Let the number be x
There are actually 3 different statements -

1. two-thirds of a number decreased by 5 is 56
2*x/3 - 4 =56
2*x/3=60
x=90

2. 38 added to 5/9 of number gives 128
i.e 5*x/9 + 38 = 128
5*x/9 = 90
x = 162

3. sum of 2.3 and 3/5 of number gives 14.6
i.e 2.3 + 3*x/5 = 14.6
3*x/5 = 12.3
x = 4.1*5
x = 20.5

So I am doing geometry in my math class, and I can't figure how how to do some of the problems.We have angles and you have to find the degree of each one. I have an acute angle that is 38 degrees, then I have 2 more acute angles, a right angle, and an obtuse angle. I am trying to find the degree of the obtuse angle. HELP! (If it helps, the worksheet is called "What do you call it when 50 people stand on a wooden dock?" #12)

Answers

ok, so in the problem there are 5 angles given but you really only need to focus on <KNL and <MNL. these two angles are a linear pair, or supplementary, which means that they add up to 180˚. so, if <KNL is 38˚, then <MNL is 142˚. 180-38=142

hope this helped

What factor makes the number sentence true 7×4 = ?×7

Answers

The answer is 4. According to the commutative property, you can commutate (swap) numbers over and get the same result. However, it only works for addition and multiplication. For instance, x + y = y + x. Or, x * y = y * x. In our example, we have 7 * 4 = ? * 7. Because we already have 7 on the right side of the expression, the missing number will be 4.
