Answer:
el área es matemática. sí, sé que vas a traducir esto, ¡así que hola! lol me siento mal
Step-by-step explanation:
First distribute the negative over the parentheses:-
= 7s^2 + 3s - 4s^2 + 3s - 1
= 3s^2 +6s - 1
She didnt have enough
she would have 48 dollars in her jar
she she had 2 dollars to little
She saves 10 per week.......after 4 weeks, she had 90
so if she started with nothing, after 4 weeks she would have 40.....but for her to have 90, she would have had to have started with (90 - 40) = 50.
Think about it....she starts with 50....and then saves 10 for 4 weeks giving her 40......and now she has 40 + 50 = 90
so ur answer is : Roberta had $ 50 before she started to save money each week
Answer:
x=58, m<DCB=56°
Step-by-step explanation:
Ok the sum of those two angles should equal 180 degrees so,
2x+8+x-2=180
solve the equation
3x+6=180
3x=174
x= 58
M<DCB=x-2--> 58-2=56
