3/4 +4/5
find the common denominator which is 20
multiply by 5 for 3/4
(3)(5)/(4)(5)=15/20
multiply by 4 for 4/5
(4)(4)/(5)(4)=16/20
15/20+16/20
=31/20
answer:
31/20, 1 11/20 and 1.55
Answer:
x + y = 29
5x + 2y = 100
Step-by-step explanation:
Total problems = 29
x + y = 29
Total marks for 5 point problems = 5*x = 5x
Total marks for 2 point problems = 2*y = 2y
Total marks = 100
5x + 2y = 100
Answer:
a. 3x = 45
15cm

Using the equation
3x = 45
Divide both sides by 3
x = 45/3
= 15cm
The length of each side of the triangle is 15cm because an equilateral triangle has its three sides equal
