Answer:
2/10 + 7/10
9/10
Step-by-step explanation:
I did the test.
Just remember that something outside the parentheses applies to everything inside.
Examples:
3 times (x + 2) . . . . . means . . . . . 3 times 'x' <u>plus</u> 3 times 2
a (b + c) . . . . . means . . . . . ab <u>plus</u> ac
4 (w + x + y + 2) . . . means . . . 4w + 4x + 4y + 8
When somebody gives you an equation that has parentheses in it,
the first thing you're always supposed to do is get rid of them.
With the examples I just gave you, you know how to do that now.
Answer:
D) 11.
Step-by-step explanation:
y = 5x + p and the point (-2, 1) is on the line, so substituting for (-2, 1):
1 = 5(-2) + p
p = 1 - 5(-2)
p = 1 + 10
p = 11.
Answer:
Step-by-step explanation:
the answer to this problem is 14
For part A Amy's estimate is inaccurate because when adding fractions they must have the same denominators. Amy probably made the mistake of adding 1/4 and 1/3 without changing the denominators first which gave her 1/7. If she were to do it correctly then she would've ended up with 7/12 as her answer.
My work:
1/4=3/12
1/3=4/12
4/12+3/12=7/12
I hope this helps and if I gave any false information I apologize in advance.
