1 answer:

5 0

Find common denominators for $\frac{1}{2}$ and $\frac{1}{3}$ : $\\$ $\frac{1*3}{2*3}= \frac{3}{6} \ and \ \frac{1*2}{3*2}= \frac{2}{6}$ $\\$ Subtract: 3/6 - 2/6= 1/6 Therefore, your answer is $\boxed{ \frac{1}{6}}$ . Hoped I helped. :)

Riley used the distributive property to find the product of 37 and 24. Which expression

Viktor [21]

Answer:

The expression Riley could have used to find the product of the two numbers is 24 × (30 + 7).

Step-by-step explanation:

The distribution property for multiplication is:

$a\times (b+c)=a\cdot b+a\cdot c$

In this case we need to determine the product of 37 and 24.

Compute the product as follows:

$37\times 24=24\times (30 +7)$

$=(24\times 30)+(24\times 7)\\=720+168\\=888$

Thus, the product of 37 and 24 is 888.

Find a particular solution to y" - y' + 9y = 3 sin 3x

Dima020 [189]

Answer:

cos3x

Step-by-step explanation:

y" - y' + 9y = 3 sin 3x

$D^{2}y-Dy+9y=3 sin3x$

$y=\frac{3 sin 3x}{(D^{2} -D+9}=3 sin 3x$

here $D^2$ will be replaced by $\alpha^2$ where $\alpha$ is coefficient of x

$y=\frac{3 sin 3x}{-3^{2} -D+9}$

$y=-3\frac{sin 3x}{D}$

$y=-3\int\ {sin 3x} \, dx$

$y=-3\frac{cos3x}{-3}$

y=cos3x

hence Particular solution is cos3x

An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15.7 inches, so the equa

yarga [219]

Answer:

[c] The value of w cannot be a negative number.

[d] Substitution is used to replace the variable l with a value of 20.

[e] The subtraction property of equality is used to isolate the term with the variable w.

Step-by-step explanation:

To figure out which steps of the solution are true, let us solve.

2 l plus 2 w equals 62 -> 2l + 2w = 62

----

2l + 2w = 62

2(20) + 2w = 62 <- Substitution is used to replace the variable l with a value of 20.

40 + 2w = 62

2w = 22 <- The subtraction property of equality is used to isolate the term with the variable w.

w = 11

This means that the value of w is not 10 feet so the first option is incorrect. This shape is a rectangle, so the value of w cannot be 0. Since we cannot have a negative measurement, option three is incorrect. This leaves us with the last three options as our answer, shown by the work above.
