The product of 1 1/2 and 2 is

Over [174]

Method 1:

Convert the mixed number to the improper fraction:

$1\dfrac{1}{2}=\dfrac{1\cdot2+1}{2}=\dfrac{3}{2}$

Make the product:

$1\dfrac{1}{2}\cdot2=\dfrac{3}{2}\cdot2$

<em>canceled 2</em>

$=\dfrac{3}{\not2_1}\cdot\not2^1}=\boxed{3}$

Method 2:

$1\dfrac{1}{2}=1+\dfrac{1}{2}$

$1\dfrac{1}{2}\cdot2=\left(1+\dfrac{1}{2}\right)\cdot2$

<em>use the distributive property a(b + c) = ab + ac</em>

$(1)(2)+\left(\dfrac{1}{2}\right)(2)=2+1=\boxed{3}$

The line whose slope is 4 and intersects the line 2x - 4y = 8 at x = 6 has the equation:

SCORPION-xisa [38]

2x - 4y = 8 → -4y = -2x + 8 → y = $\frac{1}{2} x$ - 2

We know the slope (m) = 4, need to find y-intercept (b)

y = 4x + b

$\frac{1}{2} x$ - 2 = 4x + b

$\frac{1}{2} (6)$ - 2 = 4(6) + b

3 - 2 = 24 + b

1 = 24 + b

-23 = b

Equation: y = 4x - 23

A rectangle has a length (x2 + 4y) unit and a breadth of (-2x + y3) unit. Find its perimeter

Ivahew [28]

Step-by-step explanation:

how do we find area? Length x width, right?

Let's break up each part.

3x3y2 = 3(x)(x)(x)(y)(y)

5x2y3 = 5(x)(x)(y)(y)(y)

Combining everything we have, 3(5)(x)(x)(x)(x)(x)(y)(y)(y)(y)(y). That's 15x5y5.

We multiply the coeffiecients and add exponents with the same base.

Hope this helps!

Write two subtraction equations to show how to find 15 - 7

Jobisdone [24]

15 -7= 8 or 7-15= 8 I realize that that looks crazy... but yr going into the negative numbers... so, you can really subtract 15 from 7 Hope that this helps! :)
