Answer:
B, C, F
Step-by-step explanation:
Given:
Subtract the second equation from the first equation:
Option B "The x coordinate of the solution is 9" is ture
Substitute it into the first equation:
Option F "The y coordinate of the solution is -8" is true.
Point (9,-8) is in the IV quadrant, so option C is true.
A: 8*9= 72 or 72 because it is the lowest multiple of 8 and 9
B: euclidean theorem (35,63) (35,28) (7,28) (7,0) gcf= 7 or 7 because 7 is the biggest number that goes into both numbers.
C: 7(5+9) or 35 is a factored into 7 and 5 and 63 is factored into 7 and 9 and 9 is factored into 3 and 3
Answer:
x = 24.4°
Hope this helps... Have a good day!!
You can write the proportion as 2 equal fractions or as two equal ratios.
or 12 pens:$10 = x pens:$15You can buy x pens for 15 dollars. One way to find x is by cross multiplying the fractions.
10x=12×15
10x=180
----- -----
10 10
x=18
You can buy 18 pens for $15.
