Answer:

$\frac{(a - 8)}{3} = \frac{(a - 3)}{2} \\ 2(a - 8) = 3(a - 3) \\ 2a - 16 = 3a - 9 \\ 3a - 2a = - 7 \\ a = - 7$

Answer:

y=20

Step-by-step explanation:

0.6(y-10)=6

0.6y-6=6

0.6y=12

y=12/0.6

y=20

the mistake is added 10 to both sides

A bag of skittles has 50 pieces of candy what percentage is orange ps. there are 11 orange skittles

Oliga [24]

Answer:

I think the answer is 22% but I am not sure

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 50 is 100% since it is our output value.

Step 2: We next represent the value we seek with X

Step 3: From step 1, it follows that 100%=50

Step 4: In the same vein, x%=11.

Step 5: This gives us a pair of simple equations:

100%=50(1).

X%=11(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the left hand side of both equations have the same unit; we have

100% / X% = 11 / 50

X = 22%

Step 7: Taking the inverse (or reciprocal) of both sides yields

X% / 100% = 11 / 50

Therefore, 11 is 22% of 50.

You can set up your proportion as $\frac{3}{1}$ * $\frac{2}{7}$ you then multiply across to get $\frac{6}{7}$ . Since this number is less than 1, it's definitely less than 3.

Name the property that the statement illustrates.

kolezko [41]

Answer:

Transitive property of segment congruence

Step-by-step explanation:

The reflexive, symmetric, and transitive properties are the criterion for an equivalence relation. In terms of congruence,

The reflexive property states that $\overline{XY} \cong \overline{XY}$ (a segment is congruent to itself)
The symmetric property states that if $\overline{AB} \cong \overline{CD}$ , then $\overline{CD} \cong \overline{AB}$ (this is essentially commutativity)
The transitive property states that if $\overline{AB} \cong \overline{CD}$ and $\ovelrine{CD} \cong \overline{EF}$ , then $\overline{AB} \cong \overline{EF}$ .
