Answer:
90
Step-by-step explanation:
87 is closer to 90 than to 80, so it rounds to 90 when rounded to the nearest 10.
Y = 3x - 2
I assume this is what they mean;
3(1)- 2 = 1 for <span><span>x = 1
</span>Fill in the x's with the following numbers. so first... (x = 2)
</span>y = 3x - 2
3(2) - 2
multiply 3 and 2 and then minus 2
which equals 4 all together
y=4
therefore;
3(2) - 2 = 4
For x = 3
Fill in the x with 3 in the equation
3x - 2 = y
3(3) - 2 = y
9 - 2 = y
equals 7
so...
3(3) - 2 = 7
Do the same rule with number 4 :)

Answer:
-2 4/7
Step-by-step explanation:
−3 2/7 − (−5/7)
Subtracting a negative is like adding
−3 2/7 + (5/7)
Since the signs are difference we subtract and take the sign of the larger number
3 2/7 - 5/7
Borrow from the whole number
2+ 7/7 + 2/7 - 5/7
2 9/7 - 5/7
2 4/7
The sign of the larger number is negative so add the negative sign
- 2 4/7
1/2*-3 1/2 = -21/4 = -5 1/4= <em>-5.25</em>
I hope this helps!!
