The given system of equations are :

4x + 2y=7

5x-6y=9

a c we have 4 2

b d 5 -6.

Comparing the two matrix we have a=4,b=5,c=2,d=-6

The question is asking us to find the value of a-b+c+d

Substituting the values of a,b,c,d we have:

a-b+c+d=4+(-5)+2+(--6)

=4-5+2-6=-11.

The length of a parasite in experiment A is 2.5 × 10–3 inch. The length of a parasite in experiment B is 1.25 × 10–4 inch. How m

torisob [31]

We have been given that :-

The length of a parasite in experiment A is $2.5 \times 10^{-3}$

The length of a parasite in experiment B is $1.25 \times 10^{-4}$

Let us write the the length of the parasite in experiment A in the exponent of -3.

$1.25 \times 10^{-4}= 0.125 \times 10^{-3}$

Clearly, the length of parasite in experiment A is greater than the length of parasite in experiment B.

The difference in the length is given by

$2.5 \times 10^{-3} -0.125 \times 10^{-4}$

$=2.375 \times 10^{-3}$

Therefore, the length of the parasite in experiment A is $=2.375 \times 10^{-3}$ inches greater than the length of the parasite in experiment B.

6=1-b b=? D: help please

pishuonlain [190]

Hey there! :)

6 = 1 - b

Like I mentioned in my previous answer, we must isolate our variable. In this case, our variable is b.

So, our first step is to subtract 1 from both sides.

6 - 1 = 1 - b - 1

Simplify.

5 = b

Therefore, b = 5
