Answer:
X= 29.5, Y=5
Step-by-step explanation:
If im reading the question correctly it tells you Y is 5, and that X is multiplied by two so half of 59 since we already know that Y is 5 is 29.5
J=john's age now
s=sam's age now
j=3 times s
j=3s
in five years (j+5,s+5)
j+5=2 times (5+s)
j+5=2(s+5)
j+5=2s+10
subtract 5 from both sides
j=2s+5
use other equation
j=3s
j=2s+5
subsitute
3s=2s+5
subtract 2s
s=5
sam=5
j=3s
j=3 times 5
j=15
john=15
sam=5
Answer:
x= -2
Step-by-step explanation:
-1/3(9x-27)=15
Multiplying both sides by -3
9x-27=15×(-3)
9x-27=-45
Now
Add 27 to both sides
9x=-45+27
9x=-18
Divide both sides by 9
x= -2
Answer:
Answer = 140
Step-by-step explanation:
360 = 9x + 14x + 4x + 90
360 - 90 = 27x
270 = 27x
x = 270 / 27
x = 10
14 x 10 Angle F
Measure of angle F = 140
Answer:
(c, b)
Step-by-step explanation:
Add the coordinates together and divide by 2
x coordinates: 2c + 0 = 2c, divided by 2 = c
y coordinates: 0 + 2b = 2b, divided by 2 = b
