23) Store A: y=6.30÷2
y=3.15
Store B: y=3.2
Store C: y=3.25x
y=3.25 so Store A sells the cheapest so (A) is the answer
24) the area uses half of the diameter, not the whole diameter. so the answer is 5.5pi^2 (B)
25) 1/2 × 1/2 = 1/4 × 1/2 = 1/8 (D)
26) was done correctly and (D) is the correct answer
27) 2 (x-3) +1 =19
2 (x-3) = 19 - 1
(x-3) = 18 ÷ 2
x-3 = 9
x= 9+3
x=12 (D)
Step-by-step explanation:
The unit price per kg is $5, to find this divide the 9 kilograms into the price $45 the answer is what each kilogram is worth
Combine your like terms: 5v + 5 = 5v +4
subtract the 5v and 4 from each side: 0 = 1
because 0
1, there is no solution
Answer:
D) {1, 2, 3}
Step-by-step explanation:
Simply solve for m given our equation:
<em>11 = 3.50 + 2.50m</em>
Start by subtracting 3.50 on both sides:
<em>7.5 = 2.50m</em>
Next, divide by 2.50 on both sides to obtain our value for m:
<em>3 = m</em>
Now since we're looking for a complete set of values, we have to consider all values that are 3 and below for m. This makes D) our answer
