Answer:
x = 10
Step-by-step explanation:
Hey there!
To solve this question we will use PEMDAS (order of operations)
4x−7=8x+33
Subtract 8x from both sides.
4x−7−8x=33
Combine 4x and −8x to get −4x.
−4x−7=33
Add 7 to both sides.
−4x=33+7
Add 33 and 7 to get 40.
−4x=40
Divide both sides by −4.
x= 40/-4
Divide 40 by −4 to get −10.
x=−10

I'd say 50% because out of 6 numbers 3 of them are odd.
3 probably. If 2 plates break out of 150 then you know that dividing 150 with 2 you get 75 and that means that 75 = 1 broken plates and which means that the next weak will be 1 broken plate. 150+75=225.

Answer:
8784 mm²
Step-by-step explanation:
15 cm = 150 mm
Surface area

= 3600 + 5184
= 8784 mm²
