For b it's 39 because you multiply 5 and 7 giving you 35 then add 4 Wich equals 39. I might be incorrect. check it out.
7 because 13-6 is equal to 7
Answer:
This is weirdly written, but let's try to solve it:
M is the mass of Molly
A is the mass of Arthur
G is the mass of Ginny.
We can represent the weight as:
(M + A) + G
or as:
A + (G + M)
the first situation shows that Molly and Arthur are weight together (this is why their weight is shown as only one), and then they weight Ginny alone.
The second situation shows that Arthur is weight alone, and Ginny and Molly are weight together (this is why their weight is written as only one)
Answer:
y = 2
Step-by-step explanation:
Since the line is horizontal there cannot be any slope
3z + 6
3z and 6 has greatest common factor, that is 3. Divide 3z and 6 by the greatest common factor (3).
3z ÷ 3 = z
6 ÷ 3 = 2
So, we could work on the expression as following.
3z + 6
= 3 × z + 3 × 2
From the expression above, we should separate 3 from z and 2 by a parenthesis to make distributive property.
3 × z + 3 × 2
= 3(z + 2)
SUMMARY
3z + 6
= 3 × z + 3 × 2
= 3(z + 2)
