2(x+10)+3x=85
2x+20+3x=85 I used Distributive property
(2x+3x) +20=85 Combine like terms
5x+20-20=85-20 now i need to get rid of the 20 so i subtract it (the reason for this is because it is positive you have to so the oposite, in this case subtract) from that side, and what you do to one side you have to do to the other
5x=65 is what you have now
5x/5=65/5 Now i need to get rid of the 5 by divition, so i do it to both sides
x=13 is the answer

Branliest please!!!

Solve this equation-6x^2=-144q

joja [24]

Answer:

4.9

Step-by-step explanation:

-6x2 = -144q

Divide both sides by -6

-6x2/-6 = -144/-6 q

X2 = 24q

Square root both sides

X = square root of 24q

X =4.9√q

Use the distance formula to calculate the length of the leg CD

Karo-lina-s [1.5K]

To calculate the distance between two points on the coordinate system you have to use the following formula:

$d=\sqrt[]{(x_1-x_2)^2+(y_1-y_2)^2}$

Where

d represents the distance between both points.

(x₁,y₁) are the coordinates of one of the points.

(x₂,y₂) are the coordinates of the second point.

To determine the length of CD, the first step is to determine the coordinates of both endpoints from the graph

C(2,-1)

D(-1,-2)

Replace the coordinates on the formula using C(2,-1) as (x₁,y₁) and D(-1,-2) as (x₂,y₂)

$\begin{gathered} d_{CD}=\sqrt[]{(2-(-1))^2+((-1)-(-2))}^2 \\ d_{CD}=\sqrt[]{(2+1)^2+(-1+2)^2} \\ d_{CD}=\sqrt[]{3^2+1^2} \\ d_{CD}=\sqrt[]{9+1} \\ d_{CD}=\sqrt[]{10} \end{gathered}$

The length of CD is √10 units ≈ 3.16 units

Water starts out at a temperature of 62 F . It is heated such that its temperature increases at a rate of 8 F per minute. It tak

bogdanovich [222]

Answer:

Step-by-step explanation:

since it starts at 62 and finishes at 150 u can find out that the increase in temp is 150F and since it increases by 8 every minute u can come to find that the increase in temp (150) divided by the amount it increases 8 is 18.75 which is the amount of minutes it took
