Hello!
First of all, 6 and 10 are not prime numbers as they both have at least two pairs of factors (one factor pair plus one and itself).
Anything multiplied by two is even. Therefore, a) 2 counterexamples the statement. Just to show why 7 doesn't work, seven multiplied by 3 is 21, which is odd, and 7 times 7 is 49, and 7 times 5 is 35 (all prime multipliers). The only one that works is two.
I hope this helps!
Answer:
the answer will be 86%
Step-by-step explanation:
first you (70x30=2100)
20x62=1240
2100-1240=860
and finally
you say 860÷10=86%

Answer:
4
____________________
Step-by-step explanation:
Just solve the equation 5-√x = 3
So, let’s solve it:
5-√x = 3 ⇔ 5-3=√x ⇔ √x = 2 ⇔ x=4
Then ?=4
:)
The sentence in numerical form is 5x/7≤10
to solve, multiply by 7
5x≤70
lastly, divide by 5
x≤14
