Answer:
52.5
Step-by-step explanation:
Since ED ≈ AD, ∆AED is a isosceles triangle where <EAD and <AED has same angle measurement
Now, m<B = 105°, since ABCD is a parallelogram, <B = <D
so, m<ADC = 105° so, m<ADE = 180°-105° = 75°
Now, m<EAD+m<AED+m<ADE = 180°
or, m<AED+m<AED+m<ADE = 180°
or, x+x+75°=180°
or, 2x=180+75°
or, 2x=105°
or, x=52.5°
Answer:
? = 3
Step-by-step explanation:
To find the value of ?, substitute one of the ordered pairs from the table [except (0, 0)] into the given formula and solve for ?.
Given formula:
Substitute x = 1 and y = 3 into the formula:
To isolate ? divide both sides by 1:
Therefore, ? = 3:
Check by inputting another value of x from the table into the found formula and comparing the calculated y-value:
Answer:
2
Step-by-step explanation:
5+1+7+x+3+2+4=x+22
x+22 is divisible by 3,
multiple of 3 are 3,6,9,12,15,18,21,24,27,...
if x=2 ,then x+22=2+22=24
so smallest number is 2
now, "A" is the accumulated amount, including the earned interest, how much interest was it earned? well, is just A - P.
1. Simplify both sides
−6n=−5−5n
−6n=−5+−5n
−6n=−5n−5
2. Add 5n to both sides
−6n+5n=−5n−5+5n
−n=−5
3. Divide both sides by -1.
−n
/−1
=
−5
/−1
n=5
So the variable n, is equal to 5
