Answer:
The answer is: amount of flour used for bread and brownies is same
Step-by-step explanation:
Step 1:
Assume;
Flour used for cookies = x
Flour used for bread = z
Flour used for brownies = y
Flour used for cookies = a
Step 2:
Now, for bread as mentioned flour used for bread is one fourth less than flour used in cookies therefore;
z = x - (1/4)x
z = x-0.25x
z = 0.75x
Step 3:
Now, for cookies as mentioned flour used for cookies is one third more than flour used in brownies therefore;
x = (1/3)y + y
x = 0.33y + y
x = 1.33y
Step 5:
Value of z from step 2:
z = 0.75x
now put value of x from step 3 in above equation;
z= 0.75 (1.33y)
z = (1) y
hence proved;
z = y

Answer: 150 pounds
Step-by-step explanation:
Let her initial weight be represented by x.
Since Shep had lost 16% of his weight, which was 24 pounds. Shep weight before he was put on a diet would be:
16% × x = 24
0.16 × x = 24
0.16x = 24
x = 24/0.16
x = 150 pounds
Answer:
71 %
Step-by-step explanation:
Paper 1 :
65% of 120 = 0.65 X 120 = 78
Paper 2 :
80% of 80 = 0.8 X 80 = 64
Total Percentage:
Add the two scores 78 + 64 = 142
Add the what it was out of 120 + 80 = 200
Use (Score / Total marks available) X 100
(142 / 200) X 100 = 71
Answers:
- x = 3
- CD = 21
- DE = 16
- CE = 21
=============================================================
Explanation:
The congruent base angles are D and E. Opposite those angles are the sides CE and CD. These opposite sides are the same length.
CE = CD
16x-27 = 4x+9
16x-4x = 9+27
12x = 36
x = 36/12
x = 3
This x value then leads to the following:
- CD = 4x+9 = 4*3+9 = 12+9 = 21
- DE = 7x-5 = 7*3-5 = 21-5 = 16
- CE = 16x-27 = 16*3-27 = 48-27 = 21
We see that CD and CE are both 21 units long, which helps confirm we have the correct x value.
