Answer:

x=48

Step-by-step explanation:

5.40(10)+2.50(x)=3.00(10+x)\\\\54.0+2.50x=3.00(10)+3.00(x)\\\\54+2.5x=30.0+3.00x\\\\54+2.5x=30+3x\\\\54+2.5x-2.5x=30+3x-2.5x\\\\54+0=30+(3-2.5)x\\\\54=30+0.5x\\\\54-30=30+0.5x-30\\\\24=0.5x\\\\10(24)=10(0.5x)\\\\240=5x\\\\\frac{1}{5} (240)=\frac{1}{5} (5x)\\\\48=x\\\\x=48

Inga [223]

Answer: 22

Step-by-step explanation:

She sold two tubs of Oatmeal Raisins and it's 6 dollars a tub so we can do 6*2 or 6+6 (doesn't matter). We get $12. Then, she also sells 2 tubs of Peanut Butter, and since it's $5 a tub, then we do 5*2 or 5+5 to get 10. We add 12 and 10 (12+10) and get 22.

I'm not sure if this is right because you added $22, $24, $20, and $11 and I'm not sure what the purposes of those are.

Algebra 2 (picture shown)
TEA [102]

Answer:

<em>M(13)=14.3 gram</em>

Step-by-step explanation:

<u>Exponential Decay Function</u>

The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

C(t)=C_o\cdot(1-r)^t

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.

The equation of the model is:

M(t)=M_o\cdot(1-r)^t

M(t)=970\cdot(1-0.277)^t

Operating:

M(t)=970\cdot 0.723^t

After t=13 minutes the remaining mass is:

M(13)=970\cdot 0.723^{13}

Calculating:

M(13)=14.3 gram
