We are asked to find the length of
, which measures
. Using the segment addition postulate, we can add the two given expressions for
and
and make it equal to the expression for
.
We've found the value of
, but we aren't done yet. We need to plug in the value we got for
into the expression for
, which is
. Therefore,
. Hope this helped and have a great day!
Answer:
3* 2*3*2 is n
Step-by-step explanation: well find a way to put 3 and 2 two times in expressions and expressions have no equal signs steer clear of that.
Answer:
There are 32 dimes and 25 quarters.
Step-by-step explanation:
q + d = 57 or q = 57 - d
25q + 10d = 945
substitute first equation into second equation:
25(57 - d) + 10d = 945
1425 - 25d + 10d = 945
-15d = -480
d = -480/-15 = 32
using first equation:
q = 57 - 32 = 25
check using second equation:
25(25) + 10(32) = 945 checks
Answer:
x = -8
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
-1x = -8 - 2x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Simplify: -x = -8 - 2x
- Add 2x on both sides: x = -8
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: -1(-8) = -8 - 2(-8)
- Multiply: 8 = -8 + 16
- Add: 8 = 8
