Let x = hats she knitted
Less than means to subtract and it’s an order switcher so it would be
2x - 6 = 78
First step: Add six to both sides -6 + 6 = 0 6 + 78 = 84
2x - 6 = 78
+ 6. +6
2x = 84
Second step: Divide the coefficient on both sides, two is the coefficient
2x/2 = x
2/84 = 42
Therefore, the answer is x= 42
Answer:
40
Step-by-step explanation:
5+1 3/8n=60
Subtract 5
1 3/8n=55
11/8n=55
8/11(55/1)
n=40
Answer:
<u>The correct answer is B. 82</u>
Step-by-step explanation:
The numbers are 56 and 26. Let's prove it:
56/5 = 11 and a remainder of 1
56/6= 9 and a remainder of 2
26/5 = 5 and a remainder of 1
26/6 = 4 and a remainder of 2
56 + 26 = 82
<u>The correct answer is B. 82</u>
The first one is 15, second 25, third 35
Hello :
f(x) = 9x-6
g(x) =<span>√(x-4)
</span>(f0g)(x) = f(g(x)) exist if g(x) exist and f(g(x)) exist.
g(1) no exist because : √(1-4) =√(-3) ... no real
conclusion : 1 is not in the domain of : f0g
