Write the following phrase as an algebraic expression and simplify Four-sevenths of a number, increased by fifteen
The answer is
(Simplify your answer.)

4/7n+15

Step-by-step explanation:

Let the number be n

4/7 of a number means: 4/7 times a number (n). So 4/7n then, increase (add) that by 15

you'll get the equation 4/7n+15

∠DFG and ∠JKL are complementary angles

Measure of each angle

Given :

∠DFG and ∠JKL are complementary angles. m∠DFG = x + 5,

and m∠JKL = x − 1

When two angles are complementary then the sum of angles is 90 degrees

∠DFG and ∠JKL are complementary angles.

So,

Now replace the expressions and solve for x

Now replace x with 43 and find out each angle
