Answer:
45/4
Step-by-step explanation:
We can interpret the question to have two equation which can be solve simultaneously
a+b=7------------(1)
a-b=2------------(2)
From eqn(2) make a subject of formula
a=2+b--------(3)
Substitute the (3) into eqn(1)
a+b=7------------(1)
2+b+b=7
2b=7-2
2b=5
b=5/2
From equation (3) substitute value of b to find a
a=2+b--------(3)
a= 2+5/2
a=9/2
Then What is the value of a x b ?
9/2× 5/2
=45/4
They’re all -4 ,, what exactly are you asking ?
35 :) If you change the percent into a decimal (0.70) and multiply that by 50, you will get the answer!
D as you can see on the number line d is 1/3 of the way to -2
Answer:
1
Step-by-step explanation:
Let's start by prime factorizing (finding the prime factors) of 16 and 21:
We can see that they DO NOT have any common factors, meaning that their greatest common factor is 1.
