Six less than seven times a number: 7n - 6
eight more than five times a number: 5n + 8
both angles are corresponding, the corresponding angles are equal.
so
7n - 6 = 5n + 8
2n = 14
  n =7

so 

7n - 6 = 7(7) - 6 = 49 - 6 = 43
5n + 8 = 5(7) + 8 = 35 + 8 = 43

answer
each angle = 43 degrees

11. Four less than a number tripled is the same number increased by ten.<br> What is the number?
Sphinxa [80]

Answer:

7

Step-by-step explanation:

first, we would set up an equation. let 3x-4 represent "four less than a number tripled". "a number" would be represented by x. let x+10 represent "the same number increased by 10".

set 3x-4 and x+10 equal to each other:

3x-4=x+10

next, we would solve this equation for x. first we would get the x together on one side of the equation. we would do this by subtracting x from both sides to remove it from the right side of the equation:

2x-4=10

then, we would get the 2x by itself. we would do this by adding 4 to both sides:

2x=14

finally, we would divide each side of the equation by 2 to find x:

x=7.

The number is 7.

A can do a piece of work in 4 hours and B can do it in 6 hours. How much time would they take working together to finish the wor
Kipish [7]

Answer:

2.4 hours

Step-by-step explanation:

Let total work = X

Rate of work done = X ÷ time

Rate of A = X/4

Rate of B = X/6

If they work together, rate is the sum of their individual rates, i.e.

X/4 + X/6

= (3X + 2X)/12 (taking LCM)

=5X/12

Rate = X/time

5X/12 = X/time

time = X÷(5X/12)

time = X × 12/(5X)

time = 2.4 hours

Shortcut:

Product of individual times/sum of individual times

= (4×6)/(4+6)

=24/10

=2.4 hours
