Answer: -0.15
Explanation:
0.15=x0.3
We move all terms to the left:
0.15-(x0.3)=0
We add all the numbers together, and all the variables
-(+x0.3)+0.15=0
We get rid of parentheses
-x0.3+0.15=0
We move all terms containing x to the left, all other terms to the right
-x0.3=-0.15
x=-0.15/1
x=-0.15
Answer:
B.) 317
Step-by-step explanation:
100/2 = 50
124/2 = 62
180/2 = 90
634/2 = 317
So Regina has 120 coins=total
120=total
we will use q=number of quarters and d=number of dimes
120=d+q
she has 10 more dimes than quarters
d=q+10
so if we susitute this into the equation then we get
120=(q+10)+q
add like terms
120=2q+10
subtract 10 from both sides
110=2q
divide both sides by 2
55=q
she has 55 quarters
subtitute into second equation
d=10+55
d=65
dimes=65
quarters=55
Use the formula I = Prt. Plug $2300 into P.
Plug 7.5% (decimal form is 0.075) into r.
Plug 10 into t.
