4m + 5n = 25 solve for N

Answers

Answer 1

Answer: Isolate n.

First subtract 4m.
5n = 25 - 4m

Divide by 5 to get n by itself.
n = 5 - 4/5m

That's your final answer.

Answer 2

Answer:

Add -4m to both sides

4m+5n -4m = 25-4m

5n = -4m +25

Divide both sides by 5

5n/5 = -4m+25/5

n = -4/5 m +5

I hope that's help ! If you have questions please let me know

n = -4/5

What is the area of the figure? A. 90 mm2 B. 110 mm2 C. 130 mm2 D. 180 mm

Answers

I see two shapes in the given figure. A rectangle and a triangle.

We need to get the area of the rectangle and triangle. We then deduct the area of the triangle from the area of the rectangle to get the area of the shaded portion.

Area of the rectangle = length * width
A = 11 mm * 10 mm
A = 110 mm²

Area of the triangle = (hb)/2
A = [(11mm-7mm)(10mm)] ÷ 2
A = (4mm*10mm) / 2
A = 40mm²/2
A = 20mm²

110 mm² - 20mm² = 90 mm² Choice A.

In sunlight, a vertical stick 6 ft tall casts a shadow 2 ft long. At the same time a nearby tree casts a shadow 14 ft long. How tall is the tree? Round to the nearest tenth A) 42.0 ft 
B) 85.7 ft 
C) 18.0 ft 
D) 52.5 ft<br /

Answers

The nearby tree's height is 42.0 ft, which is A

Alrighty friend, let me explain you a math.
We're gonna want to start by setting up a fraction. We'll set up the fraction as height/shadow. The stick's height is 6 feet and the shadow is 2 feet, making the fraction 6/2. The second fraction only gives us the shadow, so the fraction is x/14.
Now, we're gonna do some cross multiplication m8. 6/2 x x/14. Multiply 6x14= 84 and 2x(x)= 2x ---> 2x = 84
Do you some basic algebra here, and divide both sides by 2.
Your final answer is 42, so the tree is 42 feet tall.
