12−n⋅5=52
n÷5+12=52
12−n÷5=52
n⋅5+12=52
The equation 'n⋅5+12=52' correctly models the sentence 'Twelve more than the product of a number and 5 is 52'. This equation states that when a number is multiplied by 5 and 12 is added to the resulting product, the total is 52.
The question provides a phrase which can be expressed as an equation in mathematics. Given the phrase 'Twelve more than the product of a number and 5 is 52', we understand that 'product' refers to multiplication, 'number' is the unknown we are solving for, typically denoted by 'n', and 'twelve more than' means adding 12. Consequently, the mathematical equation that models the sentence is: n⋅5+12=52. This equation implies, the product of a number and 5, to which 12 is added, results in 52.

The equation that models the sentence is n⋅5+12=52 which has a value of 8.
The correct equation that models the given sentence is n⋅5+12=52.
To solve this equation, we need to isolate the variable n.
We can start by subtracting 12 from both sides of the equation:
n⋅5 = 52 - 12
n⋅5 = 40
Next, we divide both sides of the equation by 5 to solve for n:
n = 40 ÷ 5
n = 8
Therefore, the value of the number is 8.

Distance in 4 hours:
Answer:
14.065
Step-by-step explanation:
First you wanna transfer it from kilometers to miles.
if 1 mile is = to 1.6 kilometers that is the same as saying
1/1.6, but because we are using 90 we plug it in and it becomes: 90/1.6 which gives you 56.25.
now we know we are going 56.25 miles per hour and because we are traveling 4 hours divide the miles per hour by 4 and you get 14.065.

If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.
Let x be the number of ml you need.
Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg
(1 ml)/(1 mg) = (x ml)/(0.1 mg)
Cross multiply.
1 * x = 1 * 0.1
x = 0.1
Answer: 0.1 ml
