Answer: white = $13, double = $14
<u>Step-by-step explanation:</u>
Let white chocolate chip dough = x
Let double chocolate chip dough = y
Mary: 3x + 2y = 67
Darryl: <u> -(3x + 4y = 95)</u>
-2y = -28
<u> ÷-2 </u> <u>÷-2 </u>
y = 14
3x + 2y = 67
3x + 2(14) = 67
3x + 28 = 67
<u> -28 </u> <u>-28</u>
3x = 39
<u>÷3 </u> <u>÷3 </u>
x = 13
The value of this number is 15 because 5x3=15

Answer:
The measure of ∠EFG is 52°
Step-by-step explanation:
Given line m is parallel to line p. m∠HEF = 39º and m∠IGF = 13º.we have to find m∠EFG.
In ΔJFG,
By angle sum property of triangle, which states that sum of all angles of triangle is 180°
m∠FJG+m∠JGF+m∠JFG=180°
⇒ 39°+13°+m∠JFG=180°
⇒ m∠JFG=180°-39°-13°=128°
As JFE is a straight line ∴ ∠JFG and ∠EFG forms linear pair
⇒ m∠JFG+m∠EFG=180°
⇒ 128°+m∠EFG=180°
⇒ m∠EFG=52°
The measure of ∠EFG is 52°
