(x+y)+(x-y)i=7+3i

x+y =7

x-y =3

add these two equations together

x+y =7

x-y =3

------------------

2x = 10

divide by 2

x=5

x+y = 7

5+y =7

subtract 5 from each side

y =2

Answer: x=5

y=2

Debora [2.8K]

Answer:

$r = 1036.725\,mi$

Step-by-step explanation:

The distance per unit grade on Earth is:

$\Delta s = \frac{2\pi\cdot (3960\,mi)}{360}$

$\Delta s \approx 69.115\,miles$

The distance between Pittsburgh and Miami is:

$r = (69.115\,mi)\cdot (40.5^{\textdegree}-25.5^{\textdegree})$

$r = 1036.725\,mi$

To paint his room ted prepared 2 gallons of a paint mixture at a ratio of 3:1 white to blue. If he later decide to dilute the co

earnstyle [38]

Answer:

White = 1.67 gallons

Blue = 0.33 gallons

Step-by-step explanation:

White : blue = 3 : 1

Total ratio = 3 + 1

= 4

Gallons = 2

White = 3 /4 × 2

= 6 /4

= 3/2 gallons

Blue = 1 / 4 × 2

= 2/4

= 1/2

If he later decide to dilute the color to a ratio of 5:1

Total ratio = 5 + 1

= 6

Total gallons = 2

White = 5 / 6 × 2

= 10/6

= 5/3 gallons

= 1.67 gallons

Blue = 1 / 6 × 2

= 2 / 6

= 1/3 gallons

= 0.33 gallons

30 Yuri has two plum trees, A and B. in his garden

telo118 [61]

Answer:

42kg

Step-by-step explanation:

We are given the amount of plums produced from Tree A. We simply need to find the amount produced by Tree B and add the two numbers up.

Step 1:

Tree B produces 10% more than Tree A, which produces 20kg of plums:

$B=\frac{110}{100} *\frac{20}{1} \\\\B=\frac{110}{5}=\\\\B=22$

Ok! Tree B produces 22kg of plums. Let us find the total amount of plums Yuri gets from both trees.

Step 2:

$Total=A+B\\\\Total=20+22\\\\Total=42$

Yuri gets 42 kg of plums from the trees.

I hope this helps! Let me know if you have any questions :)
