Answer:
3/2 - 4 = y
Step-by-step explanation:
2y - 3x = -8 original problem
2y -3x + 8 = 0 addition property of equality
-3x + 8 = -2y subtraction property of equality
3/2x - 4 = y division property of equality
Answer:
28 square metres
Step-by-step explanation:
Calculate the total surface area of the glass covered part of the rectangular aquarium
Surface area = 2(4 × 2) + 2(3 × 2)
= 16 + 12
Protective film needed = 28 square metres
Its just a matter of subbing
-7x - 4y = 6....subbing in (-2,2)...x = -2 and y = 2
-7(-2) - 4(2) = 6
14 - 8 = 6
6 = 6 (correct)
so ur solution is (-2,2)
U= uniforms
598+ 24.25u= 1762
24.25u= 1762- 598
24.25u= 1164
U= 1164/24.25
U= 48
The school purchased 48 uniforms.
Hope this helps!
