Volume is l × w × h
l = 21 in
h = 5 in
w = ?
volume = 1575 in
21 × 5 × w = 1575
105 × w = 1575
w = 1575 ÷ 105
w = 15 inches
Answer:
148⁰
Step-by-step explanation:
M< EDF = M< DFE (because the two angles are equal because the triangle has two equal sides)
2x + 8 = 3x + 4
8 – 4 = 3x - 2x
4=x or x=4
So M< EDF= 2x4+8 = 16⁰
So M< EDF + M< DFE= 32⁰
180⁰- 32⁰ = 148⁰
Answer:
4x-2y
Step-by-step explanation:
Answer: A cherry pie costs 9 and an apple pie cost 12
Step-by-step explanation:
Let an apple pie be represented by a
Let an cherry pie be represented by c
Jennifer sold 12 cherry pies and 3 apple pies for a total of 144. This can be written as:
12c + 3a= 144
Jacob sold 2 cherry pies and 9 apple pies for a total for 126. This can be written as:
2c + 9a = 126
12c + 3a= 144 ............. i
2c + 9a = 126 ........... ii
Multiply equation i by 2
Multiply equation ii by 12
24c + 6a = 288 ........ iii
24c + 108a = 1512 ...... iv
Subtract iv from iii
-102a = -1224
a = 1224/102
a = 12
An apple pie costs 12
From equation i
12c + 3a= 144
12c + (3×12) = 144
12c + 36 = 144
12c = 144 - 36
12c = 108
c = 108/12
c = 9
A cherry pie costs 9
