Answer:
-4
Step-by-step explanation:
you will have to replace the n with -7, that means,
(-7+5)2
when a number is beside a bracket, it automatically means multiply
you will have to solve the numbers in the bracket first
-7 +5 is equal to -2
then, -2 multiplied by 2 is equal to -4
Answer:
4, 2, |-3|, 0, -5, -6
Step-by-step explanation:
The ratio is 3:2, purple :green
The bag has 21 purple so to get from 3 to 21 it is multiplied by 7; so we must also multiply the 2 by 7 to keep the ratio balanced.
21:14
This expression is actually pretty easy to simplify. Since all of the actions taking place are either addition or subtraction, we can initiate the first step of removing all the parentheses/brackets from the expression.
m - {n - [p + (m + n - p)]}
simplifies to
m - n - p + m + n - p
Then, we can reorganize the expression so that like terms are next to each other, making it easier to combine the like terms, which will be the next step.
m + m - n + n - p - p
Then, we combine like terms, keeping careful watch over addition and subtaction signs.
2m - 2p
(The n's cancel out because one is negative and the other is positive)
m - {n - [p + (m + n - p)]} simplifies to 2m - 2p.
Hope that helped =)
Answer:
Step-by-step explanation: Draw a working line, l, with point B on it.
Open your compass to any radius r, and construct arc (A, r) intersecting the two sides of angle A at points S and T.
Construct arc (B, r) intersecting line l at some point V.
Construct arc (S, ST).
