Answer:
Ming must add 0.375 L of a 10% sugar solution
Step-by-step explanation:
if 3 L = 80%
1.5 L should = 40% (since it is half of 80%)
and if 40 divided by 4 = 10%
1.5 also needs to be divided by 4
so 1.5 divided by 4 = 0.375
that means Ming must add 0.375 L of a 10% sugar solution
Answer:
y = 3x - 19
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define variables
Slope <em>m</em> = 3
Random point (5, -4)
Step 2: Plug in known variables
y = 3x + b
Step 3: Find <em>b</em>
-4 = 3(5) + b
-4 = 15 + b
b = -19
Step 4: Write linear equation
y = 3x - 19
Distribute
remember
a(b+c)=ab+ac
2(2.5q+8)=2(2.5q)+2(8)=5q+16
1-5q+5q+16
1+0+16
17
