4x-7=29 < do you understand how to set that up? Now, the goal is to “get x by itself.”

4x-7=29< now add the 7 to the 29. When you cross an equals sign you change the (+/-) sign of the number you’re moving.

4x= 36< now you will just divide by 4 on both sides. This will give you x by itself on the left side of the equals sign.

x=36/4 which is 9

X=9 :))

Let the unknown number be x.

"Subtract 7 from the product of 4 and a number"

4x - 7

"the number added to 29"

x + 29

Doing the first expression results in the second expression, so the expressions are equal.

4x - 7 = x + 29

Add 7 to both sides.

4x = x + 36

Subtract x from both sides.

3x = 36

Divide both sides by 3.

x = 12

Answer: The number is 12.

Check: Subtract 7 from the product of 4 and 12:

4 * 12 - 7 = 48 - 7 = 41

12 added to 29:

12 + 29 = 41

Both expressions equal 41, so 12 is the correct value for the number.

Select the correct answer.

nordsb [41]

Answer:

A. The graph is a line that goes through the points (9,0) and (0,6).

Step-by-step explanation:

Given

$4x + 6y = 36$

Required

Select the true options

$(a)\ (9,0)\ and\ (0,6)$

This implies that"

$(x_1,y_1)= (9,0)$

$(x_2,y_2)= (0,6)$

So, we have: $(x_1,y_1)= (9,0)$

$4x + 6y = 36$

$4 * 9 + 6 * 0 = 36 + 0 = 36$

So, we have: $(x_2,y_2)= (0,6)$

$4 * 0 + 6 * 6 = 0 + 36 = 36$

<em>Hence (a) is true.</em>

Water flows into a tank according to the rate F of t equals the quotient of 6 plus t and the quantity 1 plus t, and at the same

diamong [38]

Answer:

Step-by-step explanation:

The complete question is

Water flows into a tank according to the rate F(t)= (t+6)/(1+t), and at the same time empties out at the rate E(t)= (ln(t+2))/(t+1), with both F(t) and E(t) measured in gallons per minute. How much water, to the nearest galllon, is in the tank at time t=10 minutes.

Let C(t) be the amount of water in the tank at time t. We now that the rate of change of the tank is given by

$\frac{dC}{dt}=[\tex]rate at which water flows in- rate at which water flows out. Then [tex]\frac{dC}{dt}=\frac{t+6}{t+1}-\frac{\ln(t+2)}{(t+1)}[\tex]so, the desired expression is obtained by integrating with respect to t. This leads us to [tex]C(t) = \int \frac{t+1}{t+1}+ \frac{5}{t+1} - \frac{\ln(t+2)}{(t+1)} dt=t+ 5 \ln (|t+1|)-\int \frac{\ln(t+2)}{(t+1)} dt +C$

Unfortunately, the integral $\int \frac{\ln(t+2)}{(t+1)} dt$ cannot be expressed using fundamental functions. So, the problem cannot have an specific function (if you are willing to know the complete answer, the integral of this function uses the polylogarithm function with n=2).

Since you want the exact amount of water at time, you need to give C a value, that is, you need to know an initial condition for the problem. This means, you need to know the amount of water in the tank at time 0

A stage in the shape of a semi circle had a diameter of 42 ft. What is area of the stage? Use 22/7 for π. PLZ I NEED FAST TEST

zavuch27 [327]

A semi circle is half a full circle. Find the area of the full circle and divide it by 2.

Area of a circle = pi x r ^2

R is half the diameter

Area of full circle:

Area = 22/7 x 21^2

Area = 1386 sq. Ft

Area of stage = 1386/2 = 693 square feet
