Two trains, Train A and Train B weigh a total of 349 tons. Train A is heavier than Train B. The difference in their weights is 2
Ainat [17]

Answer:

Train A = 299 tons Train B = 50 tons

Step-by-step explanation:
Train A = x

Train B = y

x+y = 349

x= y +249

Plug in one equation into another

y+249+y= 349

Simplify

2y+249=349

Subtract 249 from both sides

2y=100

Divide both sides by 2

y=50

Plug it into the x equation to solve for x

x+50=349

-50 from both sides

x=299

The polygons are similar. The area of one polygon is given. Find the area of the other polygon.
OleMash [197]

Answer:

Hello! answer: area is 6 cm2

Step-by-step explanation:

Triangle area formula: base × height ÷ 2 or base × height × 1/2 so...

12 × 16 = 192 192 ÷ 2 = 96

12 ÷ 4 = 3

16 ÷ 4 = 4

3 × 4 = 12 12 ÷ 2 = 6 therefore the area is 6 hope that helps!

Help please! I’m stuck on this one and idk what to do first!
DaniilM [7]

Answer:

10 miles

Step-by-step explanation:

This is a right triangle. This is know because of the little square in the corner that indicates a right angle. Therefore, the Pythagorean Theorem can be used.

a^2+b^2=c^2

where a and b are the legs and c is the hypotenuse.

In this triangle, 24 and x are the legs, because they form the right angle. 26 is the hypotenuse because it is opposite the right angle.

x^2+24^2=26^2

Evaluate the exponents

x^2+576=676

Now, solve for x. First, move 576 to the other side of the equation by subtracting 576 from both sides.

x^2+576-576=676-576

x^2=100

Now, x is being squared. Take the square root of both sides.

√x^2=√100

x=√100

x=10

Use appropriate units

x=10 miles

The missing side length is 10 miles.
