Answer:Walnuts cost $1.25 and chocolate chips cost $3.25
Step-by-step explanation: Make walnuts x and chocolate chips y.
3x+5y=20
6x+2y=14
Multiply the first equation by 2 and then subtract it from the second.
-(6x+10y=40)
6x+2y=14
-8y=-26
y=3.25
Plug y back into either equation and isolate x to solve for x.
6x+2(3.25)=14
6x+6.5=14
6x=7.5
x=1.25
Answer: 10
Step-by-step explanation: 10 divided by 5 is 2. 2 times 2 is 4
2x^2 + 28x + 98 =
2(x^2 + 14x + 49) =
2(x + 7)(x + 7) <==
Since we know that they have to e similar, it is a 20ft tall flagpole. the shadow of the girl is half of her height, so since the flag pole shadow is 10ft it is simple 10 multiplied by 2
Answer:
