Answer:
x = 2.25 y = 0.75
Step-by-step explanation:
2x = 9.5- 5
2x = 4.5
x = 4.5 ÷ 2
x = 2.25
know we now what is x so in the second one we evaluate x
3(2.25) + 5y = 10.5
6.75 + 5y = 10.5
5y = 10.5- 6.75
5y = 3.75
y = 3.75 ÷ 5
y = 0.75
that's it !
if you want to check your answer you can evaluate x and y so it will be like
2×2.25 + 5
= 4.5 + 5 = 9.5
and
3× 2.25 +5×0.75
= 6.75 + 3.75 = 10.5
Answer:
12
Step-by-step explanation:
just find the HCF, which will be
2² × 3 = 12
Answer:
2x + 3y=-10 is incorrect (I think)
When you mulitply something with no negative you get something with no negative

Answer:
Geometric Sequence
Step-by-step explanation:
1. Check the difference.
The difference between the 1st and 2nd term

The difference between the 2nd and 3rd term

The difference is not the same. Therefore, it is not an arithmetic sequence.
2. Check the ratio
The ratio between the 1st and 2nd term

The ratio between the 2nd and 3rd term

The ratio is the same. Therefore, it is a geometric sequence.
Answer:
Step-by-step explanation:
There's no "solving" to be done because its an expression, but im assuming the question wants you to factor.

First, factor out a b^2

Factor the trinomial. What two numbers multiply to equal -10 but add to equal -3? They are -5 and +2
