Answer:
the number is 105
Step-by-step explanation:
5(x+3) = 3(2x - 1)
5x + 15 = 6x - 3
15 = 1x - 3
(15 + 3)
x = 18
---------------------------------------------
Formula
---------------------------------------------
Sum of all exterior numbers = 360°
---------------------------------------------
Apply Formula
---------------------------------------------
z + 45 + 55 + 78 + 74 + z = 360
---------------------------------------------
Combine likes term
---------------------------------------------
2z + 252 = 360
---------------------------------------------
Take away 252 from both sides
---------------------------------------------
2z = 360 - 252
2z = 108
---------------------------------------------
Divide by 2 on both sides
---------------------------------------------
2z = 108
z = 108 ÷ 2
z = 54
---------------------------------------------
Find z + 45
---------------------------------------------
z + 45 = 54 + 45
z + 45 = 99°
---------------------------------------------
Answer: 99°
---------------------------------------------
Answer: Choice B) 3 years
--------------------------------------
Explanation:
The simple interest formula is
i = P*r*t
where,
i = interest
P = principal
r = interest rate in decimal form
t = time in years
In this case,
i = 840
P = 7000
r = 0.04 (move the decimal point 2 spots to the left go to from 4% to 0.04)
t = unknown; we'll leave it as t
Plug the given values above and solve for, or isolate, t
i = P*r*t
840 = 7000*0.04*t
840 = 280*t
840/280 = 280*t/280
3 = t
t = 3
It will take 3 years
Answer:
x = 32/3
Step-by-step explanation:
p(x) = 13
x + 7/3 = 13
x = 13 - 7/3
x = 32/3
Answer:
A and B
Step-by-step explanation:
This is a geometric sequence, because each number in the sequence is multiplied by another number to get the next number.
The common ratio is 2, because each number is multiplied by 2 to get the next number
1*2=2
2*2=4
4*2=8
Hope this helps! :)
