3(2x+2)=3x-15
mutiply the bracket by 3
(3)(2x)(3)(2)= 6x+6
6x+6= 3x-15
move 3x to the other side
sign changes from +3x to -3x
6x-3x+6= 3x-3x-15
6x-3x+6= -15
3x+6= -15
move +6 to the other side
sign changes from +6 to -6
3x+6-6= -15-6
3x= -21
divide by 3 for both sides
3x/3= -21/3
x= -7
Answer: x= -7
90-25.1=64.9
since complementary angles equal 90
hope this helped
A^2+b^2=c^2 this is the answer that i got
Answer:
<A = 41.4°
Step-by-step explanation:
Recall, SOH CAH TOA
Reference angle = <A
Hypotenuse length = 8
Adjacent length = 6
Since Hypotenuse and Adjacent are involved, we would apply CAH, which is:
Cos A = Adj/Hyp
Plug in the values
Cos A = 6/8
Cos A = 0.75
A = 41.4096221° ≈ 41.4° (nearest tenth)
Answer:
I = $ 8.00
Equation:
I = Prt
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year,
then, solving our equation
I = 80 × 0.1 × 1 = 8
I = $ 8.00
The simple interest accumulated
on a principal of $ 80.00
at a rate of 10% per year
for 1 years is $ 8.00.
