Ten. 24+26+28=78. then 78÷6=13. if there is three classes then you subtract 3 from 13 and that gives you 10
Answer:
First angle = 30°
Second angle = 60°
Third angle = 90°
Step-by-step explanation:
x + y + z = 180
y + z = 5x
z = y + 30
then:
y + (y+30) = 5x
2y + 30 = 5x
x = (2y+30)/5
then:
x + y + z = 180
{(2y+30)/5} + y + y+30 = 180
{(2y+30)/5} + 2y + 30 = 180
{(2y+30)/5} = 180 - 30 - 2y
{(2y+30)/5} = 150 - 2y
2y+30 = 5(150-2y)
2y+30 = 5*150 + 5*-2y
2y+30 = 750 - 10y
2y + 10y = 750 - 30
12y = 720
y = 720/12
y = 60°
x = (2y+30)/5
x = (2*60 + 30)/5
x = (120+30)/5
x = 150/5
x = 30°
z = y + 30
z = 60 + 30
z = 90°
Check:
x + y + z = 180°
30° + 60° + 90° = 180°
Answer:
Step-by-step explanation:
Let the age of twins Jasmine and James = x years
For Jasmine,
Karlo told Jasmine to multiply her age by 3 and add 6.
Expression will be → 3x + 6
Then multiply this sum by 2,
We get the expression → 2(3x + 6)
Karlo told James to multiply his age b 2 and add 4,
Expression → 2x + 4
Then multiply this sum by 3,
Expression → 3(2x + 4)
A). Expression for Jasmine → 2(3x + 6)
Expression for James → 3(2x + 4)
