Answer:
10.5
Step-by-step explanation:
You can use ratios to solve this problem.
The original dimensions of the photo is
5 in. by 7 in.
This can be written as:
5:7
And the next is 7.5:?
Then you can use ratios to solve this.
5:7=
7.5:?
5*1.5=7.5 so you can multiply the other side by the same thing. 7*1.5=10.5
The width is 10.5 inches.
Answer:
34 jerseys
8 Social Media ads
$2,400 Spent on Radio ads
$360 per TV ad
Step-by-step explanation:
2856/84 = 34 jerseys
2000/250 = 8
200*12 = 2400
1800/5 = 360
If you know how many you have and how much they cost multiply
If you know how much was spent and how much they cost divide
If you know how much was spent and how many you have divide
Answer:
A product of factors is zero if and only if one or more of the factors is zero. That is, if ab = 0, then either a = 0 or b = 0 (or both).
Hence (x+3)(x+12) = 0 only if (x+3) = 0 or (x+12) = 0 or both. (x+3) = 0 when x = 3.(x+12) = 0 when x = 12.
Hence the values of x that make (x+3)(x+12) = 0 are x = 3 and x = 12.
