Answer:

x = -3

Step-by-step explanation:

3x + 4= -5

Subtract 4 from both sides.

3x = -9

Divide both sides by 3.

x = -3

First subtract 4 from both sides to isolate the 3x.

That leaves us with 3x = -9.

Since x is being multiplied by 3, to get x by itself,

we need to divide both sides of the equation by 3.

So our final answer is x = -3.

What is the gcf of 25, 35 and 45
nekit [7.7K]

GCF of 25, 35 and 45 is 5

Step-by-step explanation:

The greatest factor that divides all given numbers is called the greatest common factor.

In case of 25, 35 and 45, the greatest number that will divide all three will be the GCF

For that, we have to find the factors of all numbers

25 = 1,5,5\\35 = 1,5,7\\45 = 1,3,5,9

By observing the factors we can say that the greatest common factor is 5

Hence,

GCF of 25, 35 and 45 is 5

The volumes of two similar square pyramids is 128 and 250 meters respectively. The side length of the smaller pyramid is 8 meter
Yuliya22 [10]

Answer:

Height of bigger square pyramid = 3.072 meter

Step-by-step explanation:

Using equivalent ratios to find the side of the bigger square prism

128:8 = 250:X

X = (250 x 8) ÷ 128 = 15.625

Volume of a square pyramid = a x a x h/3

Hence to evaluate the height

250 = 15.625 x 15.625 x h/3

H = 3.072 meters

If the area A of a triangle is 60sq m (square meters) and the base b is 20m (meters) what is the altitude of h
umka2103 [35]

Answer:

<u>The altitude or height of the triangle is 6 meters.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Area of a triangle = 60 m²

Base = 20 m

2. What is the altitude (h) of the triangle?

Let's recall that the formula of the area of a triangle is:

Area = (Base * Height)/2

Replacing with the real values, we have:

60 = (20 * Height)/2

60 * 2 = (20 * Height) (Multiplying by 2 at both sides)

120 = 20 Height

Height = 120/20 = 6 meters

<u>The altitude or height of the triangle is 6 meters.</u>
