Answer:
The First choice
Step-by-step explanation:
I'm assuming they just want you to simplify the expression:
1/2 × 6 + 11
3 + 11
14
Step-by-step explanation:
Assuming that the 350 taking history and the 300 taking math each includes the 270 taking both history and math, then:
N(H or M) = N(H) + N(M) − N(H and M)
N = 350 + 300 − 270
N = 380
There are 380 first-year students taking history or mathematics.
Answer:
10
Step by step explanation:
In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.
Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."
x + (-6) + (-8) = -4
x + (-6 + -8) = -4
x + (-14) = -4
x + (-14 + 14) = -4 + 14
x = 10
