Answer:
x=1
y=4
(1,4)
Step-by-step explanation:
TO SOLVE FOR X:
1. Substitute y=x+3 into the equation. This should look like this:
3x+5(x+3)=23
2. Use the distributive property.
3x+5x+15=23
3. Simplify:
8x+15=23
4. Subtract 15 from both sides. It should now lool like this:
8x=8
5. Divide both sides by 8.
x=1
TO SOLVE FOR Y:
1. Take x and substitute into original statement:
3(1)+5y=23
2. Simplify:
3+5y=23
3. Subtract 3 from both sides:
5y=20
4: Simplify:
y=4
CHECK ANSWER:
y=x+3
1. Substitute your answers
4=1+3
2. Simplify
4=4
3. Check for Truth. Is 4=4?
Yes. So your final answer is:
x=1
y=4
(1,4)
Answer:
8
Step-by-step explanation:
The measure of an inscribed angle is half the measure of the intercepted arc.
m<T = (1/2)m(arc)SU
9x - 25 = 47
9x = 72
x = 8
Answer: x = 8
Answer:
$ 4500
Step-by-step explanation:
Dejar;
Principal sea P
El tiempo sea T
Tasa sea R
Interés sea yo
De la pregunta;
R = 8%, T = 1 año, I = $ 360, P =?
De;
I = PRT / 100
100I = PRT
P = 100 I / RT
P = 100 * 360/8 * 1
P = $ 4500
