Hi there! :)
<u>Answer:</u>
r ≤ 2.5
Step-by-step explanation:
<u>-2</u>(r - 3) + 7 ≥ 8
Distribute the "-2" to the entire parentheses → -2 × r = <u>-2r</u> & -2 × -3 = <u>6</u>
-2r <u>+ 6</u> <u>+ 7</u> ≥ 8
Add the similar terms together → 6 + 7 = <u>13</u>
-2r <u>+ 13</u> ≥ 8
Subtract "13" from each side of the inequality → 8 - 13 = <u>-5</u>
<u>-2</u>r ≥ -5
Divide each side of the inequality by "-2" → -5 ÷ -2 = <u>2.5</u>
<u>r ≤ 2.5</u> ⇒ Whenever you divide an inequality by a negative number, you must flip the inequality sign!!
There you go! I really hope this helped, if there's anything just let me know! :)
(x, y)
We have the points:
(-3, 1) → x = -3 and y = 1
(0, 4) → x = 0 and y = 4
(2, 6) → x = 2 and y = 6

Answer:
35 degrees
Step-by-step explanation:
This is because the angles in a triangle are equal to 180 degrees.
So you would add the 90 degrees (because it is a right angled triangle) with the 55 degrees which would give you 145 degrees.
You would minus that from 180 degrees and that gives you 35 degrees.
Hope this helps:)
Answer:
John had $572 in his savings account.
Step-by-step explanation:
Let the total amount John took from his savings account be T.
He spent $52. That means he has $(T - 52) left.
He then spent 1/2 of what was left on presents for his friends. That is:
Which means he is left with another half of what was left, that is,
Of the money remaining, John put 4/13 into checking account.
This means that he is left with 9/13 of .
We are told that this is equivalent to the last remaining $180 that John left to charity.
=>
Hence:
=> T = 520 + 52 = $572
Hence, John took $572 from his savings account. Since this is all he had in his savings account, John had $572 in his savings account.
