Answer:
Step-by-step explanation:
The marked angles form a linear pair, so have a sum of 180°.
(4a +10) +(6a) = 180
10a = 170 . . . . . . . . . . subtract 10
a = 17 . . . . . . . . . . . . . divide by 10
__
Then the measure of angle ABC is ...
∠ABC = 4a +10 = 4(17) +10 = 68 +10 . . . . . substitute 17 for 'a'
∠ABC = 78°

to get the equation of any straight line we only need two points off of it, hmmm let's use P and Q here and then let's set the equation in standard form, that is
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
Answer:
Part A) 2(n/6) - 9
Part B) the expression would change to 2(n/6) + 9 if it said 'more than'
Step-by-step explanation:
Using proportions, it is found that:
1. 1.4 groups of 5/7 are in 1.
2. The result of 8 divided by 5/7 is of 11.2.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Applying a rule of three, to find how many groups of 5/7 are in 1, we divide 1 by 5/7, hence:
1/(5/7) = 7/5 = 1.4.
Hence 1.4 groups of 5/7 are in 1.
Following the same pattern, for item 2, we have that:
8/(5/7) = 8 x 7/5 = 56/5 = 11.2.
The result of 8 divided by 5/7 is of 11.2.
