Answer:

c = 3

c = -3

(There are two because absolute value :P)

Step-by-step explanation:

u = 7i + 24j

u = (7, 24)

||c * u|| = 75

75 = || c $\sqrt{7^{2}+24^{2} }$ ||

75 = || c $\sqrt{625}$ ||

75 = || c * 25 ||

3 or -3 = c

I am Lyosha [343]

Plug in (3,-1) into equations to see:

-1=-1 CHECK

3-2(-1)=2(3)
3+2=6
5=6 NO

This is not a solution.

sarah used 3/4 pound of blueberries to make 1/2 cup of jam. how many pounds of blueberries would she need to make a cup of jam?

Ksenya-84 [330]

Answer: She needed $1\frac{1}{2}\text{ pounds of blueberries}$ to make a cup of jam .

Step-by-step explanation:

Since we have given that

Sarah used $\frac{3}{4}$ pound of blueberries to make $\frac{1}{2}$ cup of jam.

As we need to find the number of pounds of blueberries she would need to make a cup of jam.

So, we will use "Unitary Method":

$\text{For }\frac{1}{2}\text{ cup of jam},\\\\\text{ she need }\frac{3}{4}\text{ pound of blueberries }\\\\\text{ For 1 cup of jam}.\\\\\text{She need }=\frac{3}{4}\times 2=\frac{3}{2}=1\frac{1}{2}\text{ pounds of blueberries }$

Hence, She needed $1\frac{1}{2}\text{ pounds of blueberries}$ to make a cup of jam .
