Answer:

S(saxophone)=15 T(trumpet)=5

Step-by-step explanation:

T=S-10

S-10=T

S/3=T

Which means 2/3 T and -10 are the same.

S/3=T=S-10=T

S=15

T=5

(1 pt) let t2y′′−5ty′+5y=0. find all values of r such that y=tr satisfies the differential equation for t>0. if there is more
Dafna1 [17]
Let
y = t^r \\  \\ y' = rt^{r-1}  \\  \\ y'' = r(r-1) t^{r-2}

Substitute into differential equation:
(r^2 -r) t^r - (5r) t^r + (5) t^r = 0

Factor out t^r and solve for 'r':
r^2 - r -5r +5 = 0 \\  \\ r^2 - 6r+5 = 0 \\  \\ (r-5)(r-1) = 0 \\  \\ r = 1, r=5

Sienna has 5 3/4 pounds of grapes. She eats 1/8 pound and gives 2 1/2 pounds to her brother. How many pounds of grapes does Sien
miskamm [114]

The pounds of grapes left with seinna is 3.125 or \frac{25}{8} pounds

<h3><u>Solution:</u></h3>

Given that Sienna has 5\frac{3}{4} pounds of grapes

She eats \frac{1}{8} pound and gives 2\frac{1}{2} pounds to her brother

<em><u>To find: pounds of grapes left with seinna</u></em>

We can find the pounds of grapes left with seinna by subtracting the pounds of grapes she ate and pounds of grapes she gave to brother from the total pounds of grapes she had

Pounds of grapes left with seinna = total pounds of grapes - pounds of grapes she ate - pounds of grapes she gave to brother

\text {total pounds of grapes }=5 \frac{3}{4}=\frac{4 \times 5+3}{4}=\frac{23}{4}

\text {pounds of grapes she ate }=\frac{1}{8}

\text {pounds of grapes she gave to brother }=2 \frac{1}{2}=\frac{2 \times 2+1}{2}=\frac{5}{2}

<em><u>Substituting the values we get,</u></em>

\text {Pounds of grapes left with seinna }=\frac{23}{4}-\frac{1}{8}-\frac{5}{2}

\text { Pounds of grapes left with seinna }=5.75-0.125-2.5=3.125

Thus the pounds of grapes left with seinna is 3.125 or \frac{25}{8} pounds
