Answer:
28
Step-by-step explanation:
If 50% of students are boys that means there are 30 boys and 30 girls. Then if 30% of boys are 10 and 60% of girls are 18. You add 18+10 and that gives you 28.
Y = mx + b
slope(m) = 7
(1,8)...x = 1 and y = 8
now we sub into the formula and find b, the y int
8 = 7(1) + b
8 = 7 + b
8 - 7 = b
1 = b
so ur equation is : y = 7x + 1 <===

Answer:
x = -2
Step-by-step explanation:
Equation is given as;
4 x - 5 = 2 + 3 ( x - 3 )
Step 1: Expand the brackets
4x - 5 = 2 + 3x - 9
Step 2: Collect like terms
4x - 3x = 2 - 9 - (-5)
Step 3: Simplify
x = 2 - 9 + 5
x = -2
