Answer:
y = 10/3x - 2/3
Step-by-step explanation:
10x-3y=2
-3y = -10x + 2
-3y/-3 = -10x/-3 + 2/-3
y = 10/3x - 2/3
Step-by-step explanation:
1a)you are asked to find the number of girls and boys who received prizes
1b)The given facts are that out of 60 pupils, 40 being boys, 20 being girls, joined a Math Quiz competition. 20%of boys and 15 of girls received prizes.
1c)40 boys +20 girls=60 pupils.
1d) Find the number of girls and boys that re ceived prizes
20% of 40 boys
20/100 ×40= 8 boys won prizes
15% of 20 girls
15/100×20=3 girls won prizes
1d) 8 boys+3 girls=11 pupils won prizes
Answer:
Step-by-step explanation:
First use distributive property
3(4x-2) = 12x-6
5x+9=12x-6
Now use property of equality
5x+9=12x-6
-9. -9
5x=12x-15
-12x -12x
-7x= -15
-7x divides by -7
-15 divided by -7
Answer: x= 15/7 or x= 2.143
Answer:
Step-by-step explanation:
-1/2 (7z + 4) + 1/5 (5z - 16)
-1/10 × (5(7z + 4) - 2 (5z - 16))
-1/10 × (35z + 20 - 10z + 32)
= -1/10 × (25z + 52)
