<span>2x+5=10

Subtract 5 from both sides.
2x + 5 - 5 = 10 - 5
2x = 5

Divide both sides by 2.
2/2x = 5/2
x = 5/2

5/2 can be simplified to 2 1/2 or 2.5.</span>

Work: 2x+5=10
-5 both sides
2x=5
÷2 both sides
X=5/2
Answer: x=5/2
Check your work:
2 (5/2)+5=10
5+5=10
10=10

Answer is correct

Un tanque de almacenamiento de agua instalado en una comunidad tiene forma de prisma rectangular y una capacidad de 8 000 litros

Mariana [72]

Answer:

a) la altura es de 1.6 metros

b) contendría 3750 litros

Step-by-step explanation:

1000 litros = 1m³

8000 litros = 8000/1000 = 8m³

La formula del volumen de un prisma rectangular es:

v = área de la base * altura

el área de la base es:

ab = 2.5m * 2m = 5m²

entonces:

v = 5 * altura

v = 8m³

así que:

8m³ = 5m²* altura

altura = 8m³/5m²

altura = 1.6 metros

Si la altura fuese de 75cm

1 metro = 100 centímetros

75 cms = 75/100 = 0.75 metros

entonces:

volumen = 5m² * 0.75m

volumen = 3.75m³

3.75m³ = 3.75*1000 = 3750 litros

El agua que contendría sería de:

3750 litros

Suppose the integral from 2 to 8 of g of x, dx equals 12, and the integral from 6 to 8 of g of x, dx equals negative 3, find the

Artyom0805 [142]

$\displaystyle\int_2^8g(x)\,\mathrm dx=12$

$\displaystyle\int_6^8g(x)\,\mathrm dx=-3$

Use the fact that integrals are additive on their intervals. Mathematically, if $c\in[a,b]$ , then

$\displaystyle\int_a^bg(x)\,\mathrm dx=\int_a^cg(x)\,\mathrm dx+\int_c^bg(x)\,\mathrm dx$

So we have

$\displaystyle2\int_2^6g(x)\,\mathrm dx=2\left(\int_2^8g(x)\,\mathrm dx-\int_6^8g(x)\,\mathrm dx\right)=2(12-(-3))=30$
