Answer: 15
Step-by-step explanation: The common denominator for these 2 fractions is simply the least common multiple for the 2 denominators.
To find the least common multiple or <em>lcm</em> of 3 and 5, we begin by listing the first few multiples of each number.
<em>Multiples of 3</em>
1 x 3 = 3
2 x 3 = 6
3 x 3 = 9
4 x 3 = 12
5 x 3 = 15
We skipped 0 x 3 because our lcm can't be 0.
Next we list the multiples of 5.
<em>Multiples of 5</em>
1 x 5 = 5
2 x 5 = 10
3 x 5 = 15
Notice that 15 appears in both lists so
our least common denominator is 15.
Answer:
y=2.13
Step-by-step explanation:
cross multiply
0.8/1.8=y/4.8
4.8*0.8/1.8
3.84/1.8
y=2.13
Well since y= kx you should divide 12.6 by 3
Well u do 31.2 x 18 which is 561.6 then u divide by 2 because the formula for a triangle is base x height divided by 2 so It is 280.8
Answer:
gradient m is 2
Step-by-step explanation:
the equation is y=mx+c therefore m is 2.
