Answer:
The correct equation is: 6x+12 = 30.75
And 3 people went to the movies
Step-by-step explanation:
We will write the equation to represent this scenario.
Let x be the number of people who went for movies.
Then the price of ticket for x people will be: 6.25x
They spent $12 on refreshments and a total of $30.75 so the equation will be:
solving the equation will give us total number of people
So,
Hence,
The correct equation is: 6x+12 = 30.75
And 3 people went to the movies
Answer:
The expression that could be used is (-4)(3) + (-4)() ⇒ B
Step-by-step explanation:
Let us revise the distributive property:
<em>The product of a number and the sum of 2 other numbers equal to the sum of the products of the number with the other 2 numbers</em>
We will use this rule to solve the question
∵ The product of -4 and 3 = -4 × 3
→ We can right 3 as (3 +
)
∵ 3 = (3 +
)
∴ -4 × 3 = -4(3 +
)
→ By using the rule above
∵ -4(3 + ) = (-4)(3) + (-4)(
)
∴ -4 × 3 = (-4)(3) + (-4)(
)
∴ The expression that could be used is (-4)(3) + (-4)()
