Answer:
-1/6
Step-by-step explanation:
-1/2 + ( 3/4 x 4/9)
PEMDAS says parentheses first
Rearranging the fractions
-1/2 + ( 3/9 x 4/4)
-1/2 + (1/3*1)
-1/2 + 1/3
Getting a common denominator of 6
-1/2 *3/3 + 1/3 *2/2
-3/6+2/6
-1/6
Answer:
54 pounds
Step-by-step explanation:
To find out how much flour is needed to make 9 cakes, we first need to find out how much much flour is needed to make 1 cake. For that, we need to divide 6 by 36. That will give you 6. Now that we know how much flour is needed to make 1 cake, we will just have to multiply 6 by 9 to find out how much flour is needed to make 9 cakes. That will give you 54 pounds, which is your final answer.
Applying the midsegment theorem, the <u>value of x = 5</u>
<em><u>Recall:</u></em>
- The midsegment theorem of a triangle states that the length of the mid-segment (DE) which is parallel to the third side (AC), is half the length of the third side AC of triangle BAC.
<em><u>Thus:</u></em>
DE = 1/2(AC)
2x - 3 = 1/2(x + 9)
2(2x - 3) = x + 9
4x - 6 = x + 9
4x - x = 6 + 9
3x = 15
x = 5
Therefore, applying the midsegment theorem, the <u>value of x = 5</u>
