Answers:
2x - 6y = 8 -> x = 4 + 3y
-3x + 9y = 12 -> x = -4 + 3y
Answer:
It would be 60 degrees
Step-by-step explanation:
You take the numbers and write the equation 34-(-26) to figure out the difference. You then change the signs, making it 34+26, as before you were subtracting a negative. If you complete that problem, you come to the conclusion of 60.
Drawing a king is 1/4 and drawing a black card is 26/52
Answer:
The answer is 5:12
Step-by-step explanation:
It is 5:12 because We already know that 7 pens are blue. To find the number of red pens we must subtract 12 - 7 and get 5 as the number of red pens. Now knowing the no. of red pens and total number we can say the ratio of red pens to total no. is 5:12
A) fifth = 5/5 (this is a fraction) 1/5 is 1 fifth of 1. Get what i'm saying? So then the will be <u>5 fifths in a whole
</u>
B) ok turn 2 1/3 into a improper fraction and that will be <u>7/3</u>
C) ok so 4 (a whole number) is 20/5 so you divide 20/5 with 2/5 (ignore this if you don't know what i'm talking about this is in middle school) so that will = <u>10</u>
