Kara: 30 Cassie:12
Step-by-step explanation:
N+2n-3=42
3n-3=42
3n=42+3
3n=45/3
n=15
Karas age: 2n= 30
Cassies age n-3= 12
A: Kara is old 30 years,Cassie is 12
I hope I helped
39/3 =13kph kilometers per hour
8/.5 = 16. Kpm kilometers per min
Let x and y be the two numbers.
x = y - 4
2y = 5x - 10
solve the system of equations:
2y = 5(y - 4) - 10
2y = 5y - 20 - 10
-3y = -30
y = 10
x = 10 - 4 = 6
Your answer is going to be greater than
I guess you meam 3:2 instead of 3; 3
Anyhow,
The sides of isoceles triangle are leg, leg , base
each leg =2
while the base =4
To find the number you have to divide the ratio by total and multiply into 105
The base
3/7 × 105 = 45
The leg
2/7 × 105 = 30
Therefore, The length of the base = 45 cm
