Answer:
±3
Step-by-step explanation:
4 - 7 = -3
10 - 7 = 3
Line segment AD is 4cm. Because A is the center, any lines coming off the centerpoint are congruent. So if line AC is 4cm, then line AD has to be 4cm as well.
<span>3x + 2y = 7
y = –3x + 11
replace </span>y = –3x + 11 into 3x + 2y = 7
3x + 2y = 7
3x + 2(–3x + 11) = 7
3x -6x + 22 = 7
-3x = 7 - 22
-3x = -15
x = 5
<span>y = –3x + 11
y = -3(5) + 11
y = -15 + 11
y = -4
x = 5 and y = -4
answer: </span><span>D. (5, –4)</span>
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
