Answer:
x = 13.25 kg
y = 6.5 kg
Step-by-step explanation:
Let
Large box = x
Small box = y
4x + 8y = 105 (1)
2x + 3y = 46 (2)
(Multiply (2) by 2 to eliminate x
2x + 3y = 46 (2) ×2
4x + 6y = 92 (3)
4x + 8y = 105 (1)
Subtract (3) from (1)
8y - 6y = 105 - 92
2y = 13
y = 13/2
y = 6.5kg
Substitute y = 6.5 into (2)
2x + 3y = 46 (2)
2x + 3(6.5) = 46
2x + 19.5 = 46
2x = 46 - 19.5
2x = 26.5
x = 26.5/2
x = 13.25 kg
3(2 + x)
3(2) + 3(x)
<span>With the distributive property, you can multiply numbers inside parenthesis by numbers outside a parenthesis.

x(a + 1 + 4)
x(a) + x(1) + x(4)
ax + x + 4x
The number must be distributed across every term.
Answer
Y 4, 5.41, 6
_________
X 0, 1, 2

Yes you do you only need 300g of flour to make the cake
Angles in a triangle always add to 180 degrees. 180=(8x+3degrees)+(10x-4 degrees)+91
180-91=89 89=(8x+3 degrees)+(10x-4 degrees) 89-3= 86 86+4=90
(8x+10x=18x) 18x=90
divide bothe sides by 18
x = 5
