PLS HELPP Help Solve for x X =​

Mathematics
1 answer:
Basile [38]3 years ago
4 0

Answer:

x = 9

Step-by-step explanation:

The big triangle is similar to smaller one so we can use the side lengths' proportion to find x:

7/4 = (x-3)+8/8

7/4 = (x+5)/8 cross multiply expressions

56 = 4x + 20 subtract 20 from both sides

36 = 4x divide both sides by 4

9 = x

Susan Johnson earns a yearly salary of $83,280. a. How much would Susan be paid if she were
Umnica [9.8K]
Just divide the 83,280 by 12, when you do that you get 6940. So 6940 is how much she makes per month then you take that 6940 and divide it by 4 to get what she makes per week, when you do that you get 1735.

So, Susan Johnson would earn 6940$ per month if she would be paid per month and if she was paid per week she would earn 1735$ per week.

Solve the equation. Find x.<br> 20x + 5 - 0 = 5x + 32.5*2
SVEN [57.7K]

Answer:

x = 4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

20x+5−0=5x+(32.5)(2)

20x+5+0=5x+65

(20x)+(5+0)=5x+65(Combine Like Terms)

20x+5=5x+65

20x+5=5x+65

Step 2: Subtract 5x from both sides.

20x+5−5x=5x+65−5x

15x+5=65

Step 3: Subtract 5 from both sides.

15x+5−5=65−5

15x=60

Step 4: Divide both sides by 15.

15x

15

=

60

15

x=4

Hope this helps!
