Nick is making bread dough.

LiRa [457]

Answer:

He would need $\frac{3}{2}=1\frac{1}{2}$ cups of salt.

Step-by-step explanation:

We are given that,

The recipe requires $\frac{3}{4}$ cups of flour and $1\frac{1}{8}=\frac{9}{8}$ teaspoons of salr.

As Nick wants to make the recipe using 1 cup.

Let the amount of salt needed = x

The ratio of the flour and salt will be same.

So, we have,

$\frac{\frac{3}{4}}{\frac{9}{8}}=\frac{1}{x}$

i.e. $\frac{3\times 8}{4\time 9}=\frac{1}{x}$

i.e. $\frac{2}{3}=\frac{1}{x}$

i.e. $x=\frac{3}{2}=1\frac{1}{2}$

Thus, he would need $\frac{3}{2}=1\frac{1}{2}$ cups of salt if 1 cup of flour is used.

If c-d=7 and c=3-8i what is d<br> a) -4+8i<br> b)-4-8i<br> c)4+8i<br> d)4-8i

Zigmanuir [339]

Answer:

Step-by-step explanation:

c - d = 7

c = 3 - 8i Substitute into the top equation

3 - 8i - d = 7 Subtract 3 from both sides

- 8i - d = 7 - 3 Combine

-8i - d =4 Add 8i to both sides

-d = 4 + 8i Multiply through by -1

-1*-d = -4 - 8i

d = - 4 - 8i

Looks like B is the answer.
