Let's call the number of standard boxes sold x and the number of deluxe boxes sold y.
The kg of peaches sold will be 1 for each standard box and 2 for each deluxe, so we know:
x + 2y = 12
The kg of apples sold will be 2 for each standard box and 1.5 for each deluxe, so:
2x + 1.5y = 14. Now we solve the two equations as a system:
From the 1st one:
x = 12 - 2y
We substitute in the second one:
2(12 - 2y) +1.5y = 14;
24 - 4y +1.5y = 14;
-2.5y = -10;
y = 10/2.5 = 4;
Now we substitute in the first equation:
x = 12 - 2y = 12 - 2*4 = 12 - 8 = 4.
So the shop sold 4 standard boxes (x) and 4 deluxe boxes (y).
Answer: y=-4
Step-by-step explanation:
8(3)+5y=4
24+5y=4
subtract each side by 24
5y=-20
divide by 5
5 y=-4
Answer:
360/100=3.6
30 x 3.6 = 108
10 x 3.6 = 36
From the 10 you can multiply by 5. 36 x 5 = 180
10 3.6 = 36
36 + 36 = 72. 108 + 72 = 180
180 + 180 = 360.
Angles are Red-108, Blue-36, Green-180, and yellow-36.

Step-by-step explanation:
Answer: 96°
Step-by-step explanation:
Sum of angles of a triangle = 180°
3 + 8 + 4 = 15
The biggest angle is 8/15 * 180 = 96°
