7+2x÷3=5 what is x Pls help

Paladinen [302]

Answer:

x = 4

Step-by-step explanation:

Given

$\frac{7+2x}{3}$ = 5 ( multiply both sides by 3 to clear the fraction )

7 + 2x = 15 ( subtract 7 from both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Can someone help me plz!!

ollegr [7]

Answer:

MRT or TRM

Step-by-step explanation:

RT and MR meet at point R. Point R must be included in the final angle as well as the endpoints of RT and MR. The resulting angle is thus MRT, or TRM

Plz help me i give brainliest

Anestetic [448]

Answer:

The median is 5

Step-by-step explanation:

The median is the value that is in the middle of a data set. One can find this value by lining up all of the values in the data set in ascending order (from smallest to largest). Then one will cross out answers on either side of the data set until one is left with a single value. In the event that one is left with two values, one will take the average of the two values. In other words, add the two values and then divide the result by 2.

The first step in finding the median is to list out all of the given data. Transcribe the visual data that is given in the problem into numerical data. In other words, rewrite the numbers represented by the dots as actual numbers.

1, 1, 3, 4, 4, 5, 6, 6, 6, 7, 9

Now take out numbers from each side until a single number is left in the middle.

1, 1, 3, 4, 4, 5, 6, 6, 6, 7, 9

1, 3, 4, 4, 5, 6, 6, 6, 7

3, 4, 4, 5, 6, 6, 6

4, 4, 5, 6, 6,

An object with initial temperature 120° F is submerged in large tank of water whose temperature is

nikitadnepr [17]

Answer:

$F(t)=Ts+(T0-Ts)^{e-0.2t$

Step-by-step explanation:

Newton's law of cooling states

"that the temperature of a body changes at a rate proportional to the difference in temperature between the body and its surroundings"

Newton's Law of Cooling is given by the formula

$F(t)=Ts+(T0-Ts)^{e-kt$

Where

F( t ) is the temperature of the object at a given time t

T s is the surrounding temperature

T 0 is the initial temperature of the object

k is the constant

Given k=0.2

Hence the expression is

$F(t)=Ts+(T0-Ts)^{e-0.2t$

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times

erastova [34]

Answer:

first angle be 30°

second angle be 70°

third angle be 80°

Step-by-step explanation:

first angle be x

second angle be y

third angle be z

x+y+z=180

given, y+z = 5x; z=5x-y

also, z=y+10

5x-y = y+10

5x= 10+y+y = 10+2y

x= (10+2y)/5

x+y+z=180

(10+2y)/5 + y + y+10 = 180

(10+2y)/5 = 180 -2y -10

(10+2y)/5 = 170-2y

multiply both sides by 5

10+2y = 5(170-2y)

10+2y= 850-10y

2y+10y = 850-10

12y= 840

y= 840/12 = 70°

z=y+10 =70+10= 80°

5x= (10+2y) = 10+2(70) = 10+140= 150

x = 150/5 = 30°
