The number 49 has two square roots: 7 and _____​

Answers

Answer 1

Answer:

-7

Step-by-step explanation:

Square numbers always have two possible roots: a positive and negative root. This is because two positive numbers multiply to make a positive number and two negative numbers also multiply to make a positive number

-7 × -7 is still 49, just like 7 × 7

Hope this helps!

Para que con exactitud se pueda poner líquido en dos tambos de 60 y 90 litros, respectivamente, ¿Cuál es la capacidad máxima en litros que debe tener el recipiente a utilizar? *​

Answers

Answer:

No estoy muy seguro de esta pregunta principalmente porque tuve que traducirlo del español al inglés, pero creo que el toldo es de 120 litros. Avísame si me equivoco

Step-by-step explanation:

Esto se debe a que 60 litros es el máximo que puede aguantar el más pequeño por lo que para poner 60 litros en cada uno debes tener 120 litros en total.

m/5=3(2m+1) verbal expression

Answers

Answer:

m = -15/29

Step-by-step explanation:

1) Distribute

[tex]\frac{m}{5} =6m+3[/tex]

2) Subtract 6m from both sides of the equation

[tex]\frac{m}{5} -6m=6m+3-6m[/tex]

3) Simplify

a. Find common denominator

[tex]\frac{m}{5} +\frac{5(-6)m}{5} =6m+3-6m[/tex]

b. Combine fractions with common denominator

[tex]\frac{m+5(-6)m}{5} =6m+3-6m[/tex]

c. Multiply the numbers

[tex]\frac{m-30m}{5} =6m+3-6m[/tex]

d. Combine like terms

[tex]\frac{-29m}{5} =6m+3-6m[/tex]

e. Combine like terms

[tex]\frac{-29m}{5} =3[/tex]

4) Multiply all terms by the same value to eliminate fraction denominators

[tex]5 *\frac{-29m}{5} =5*3[/tex]

5) Cancel multiplied terms that are in the denominator

[tex]-29m=5*3[/tex]

6) Multiply the numbers

[tex]-29m=15[/tex]

7) Divide both sides of the equation by the same term

[tex]\frac{-29m}{29} =\frac{15}{-29}[/tex]

8) Simplify

a. Cancel terms that are in both the numerator and denominator

[tex]m=\frac{15}{-29}[/tex]

b. Divide the numbers

[tex]m=-\frac{15}{29}[/tex]

If he arrived 2 hours before he started, what distance did liam traveled by taxi?

Answers

The answer is ten. The formula for calculating speed is as follows:

Speed = distance × time. Knowing the distance and time units is required to calculate the speed units.

Explain about the speed?

A bicycle that travels 30 meters in two seconds, for example, is moving at a rate of 15 meters per second. The speed of an object in motion varies frequently (for example, a car may travel down a street at 50 km/h, then slow to 0 km/h, and then accelerate to 30 km/h).

The rate at which a distance changes over time is referred to as speed. It has a dimension of time and distance. As a result, the SI unit of speed is formed by combining the fundamental unit of time and the fundamental unit of distance. As a result, the SI unit of speed is the meter per second (m/s).

solve 4(2x-5)=5x+4 pls​

Answers

Answer:

x=8

Step-by-step explanation:

4(2x-5)=5x+4

Distribute

8x -20 = 5x+4

Subtract 5x from each side

8x -20 -5x = 5x+4-5x

3x-20 = 4

Add 20 to each side

3x-20+20 = 4+20

3x = 24

Divide by 3

3x/3 =24/3

No Solutions

Step-by-step explanation:

The two lines never intersect

Answer:

A

Step-by-step explanation:

y = 5x + 6 → (1)

y - 5x = 7 ( add 5x to both sides )

y = 5x + 7 → (2)

Substitute y = 5x + 7 into (1)

5x + 7 = 5x + 6 ( subtract 7 from both sides )

5x = 5x - 1 ( subtract 5x from both sides )

0 = - 1 ← is False

This indicates the system has no solution
