3x+4/5=7-2x what is the solution to the equation?

Answer:

[tex](\frac{55}{2} ,\frac{37}{2} )[/tex]

Step-by-step explanation:

We have to solve this system of equations in order to find the numbers :

Let x be greater number and y be the smaller one :

[tex]\begin{cases}x-y=9\ \ \ (1)&\\ x+y=46\ \ \ (2)&\end{cases}[/tex]

[tex]\Longleftrightarrow \begin{cases}y=x-9\ \ \ (1)&\\ 2x=9+46=55\ \ \ (1)+(2)&\end{cases}[/tex]

[tex]\Longleftrightarrow \begin{cases}y=\frac{55}{2} -9=\frac{37}{2} &\\ x=\frac{55}{2}&\end{cases}[/tex]

Step-by-step explanation:

Refer to attachment*

Consider the attachment first for a better understanding, now after considering the attachment you will gotta know that, the height of the parallelogram is just same as the width of the rectangle i.e (2/5) foot and but for the base of the parallelogram we can subtract the base of one triangle from the length of the rectangle, so it will give us (3/5) - (1/25) = (2/5), so now we have breadth as well as height of the parallelogram, so now, as area of a parallelogram is given by it's height times it's base, so we will be having

[tex]{:\implies \quad \sf Area_{(Parallelogram)}=\dfrac{2}{5}\times \dfrac25}[/tex]

[tex]{:\implies \quad \boxed{\bf{Area_{(Parallelogram)}=\dfrac{4}{25}\:\: sq.\:\:foot}}}[/tex]

Hence, Option D) is correct

Well, we have another method for it, we can subtract the area of both the triangles from the area of rectangle, and now,as their base of the triangle is (1/5) foot and height is same as the width of rectangle i.e (2/5) foots, so its area will be (1/2) times base times height, but as here are two triangles, so multiplying the area of one triangle by 2 will vanish 2, so now we just have

[tex]{:\implies \quad \sf Area_{(Parallelogram)}=\bigg(\dfrac{2}{5}\times \dfrac{3}{5}\bigg)-\bigg(\dfrac{1}{5}\times \dfrac{2}{5}\bigg)}[/tex]

[tex]{:\implies \quad \sf Area_{(Parallelogram)}=\dfrac{6}{25}-\dfrac{2}{25}}[/tex]

[tex]{:\implies \quad \boxed{\bf{Area_{(Parallelogram)}=\dfrac{4}{25}\:\: sq.\:\:foot}}}[/tex]

This also, proves that the correct answer is D)

The height of the ball is 10.053 approx. when it is 13 feet from the free throw line .

The physics aspect of shooting a free throw involves distance and deviation. Distance is determined by two factors: launch angle and launch speed. Players have a choice between shooting for a larger target by using more arc or going for a shooter's touch and shooting with their ideal arc for their height.

According to the question

A basketball player shoots a free throw, where the position of the ball is modeled

x = (24cos 48°)t

y =  6.1 + (24sin 48°)t − [tex]16t^{2}[/tex]

now

13 feet from the free throw line

x = 13 feet (horizontal distance)

x = (24cos 48°)t

(24cos 48°)t = 13

t ≈ 0.8059

putting values in y to get the vertical height

y =  6.1 + (24sin 48°)t − [tex]16t^{2}[/tex]

y =  6.1 + (24sin 48°)*0.8059 − [tex]16*( 0.8059)^{2}[/tex]

y ≈ 10.053

Hence, the height of the ball is 10.053 approx.

Applying the tangent ratio, the tangents of the acute angles in the right triangle are:

tan J = 5/3

tan K = 3/5

The tangent ratio is used to find the tangents of an angle in a right triangle, or any of the legs. It is given as tan ∅ = opposite/adjacent.

Applying the tangents ratio:

tan J = opp/adj = 5/3

tan K = opp/adj = 3/5

In this case, there are 3 entrees, each with a probability of [tex]\frac{1}{3}[/tex] because the probability of selecting a hamburger (an example that could be applied to other options too) is 1 out of the 3 options. Likewise is the case with sides and drinks; the probability of selecting fries (or vegetable) out of the two options is [tex]\frac{1}{2}[/tex], and the probability of selecting milk (or juice) out of the two options is [tex]\frac{1}{2}[/tex].

Answer:

Part B : 42

Part C : 7

Step-by-step explanation:

After putting in the coordinate points the width of the rectangle is 7 units and the length is 6 units. 7*6 =42. Half of this is the area of the triangle, that is 21. Further , 1/3 of 21 is the same as 21 divided by 3, which equals 7.

Applying the sine ratio, the length of segment SV (opposite side) in the right triangle is: D. 13/√2

The sine ratio is used to solve a right triangle which is, sin θ = opp/hyp.

Given the following:

SU = 13 (hypotenuse)

θ = 45

SV = ? (opposite)

Note: sine 45 = 1/√2

Applying the sine ratio, we have:

sin 45 = SV/13

SV = sin 45 × 13

SV = 1/√2 × 13

SV = 13/√2

The equation that represent the amount in the account after t years is A = 100(1.06)^t

This is an interest on an amount of money. The formula for calculating the compound interest is expressed as;

A = P(1 + r)^t

P is the principal = 100

r is the rate = 6% = 0.06

If the interest is compounded annually, the equation that represent the amount in the account after t years is given a:

A = 100(1+0.06)^t

To the nearest cent, how much will he have in 2 years?

The value of x in each figure is 34°, 17.1° and 75° respectively.

An equation is an expression used to show the relationship between two or more numbers and variables.

From the diagram:

1) x + 146°  = 180° (sum of angles in a straight line)

x = 34°

2) x + 62.9° = 90° (complementary angles)

x = 17.1°

3) x + 105°  = 180° (sum of angles in a straight line)

x = 75°

s2:24 20

The first term that appears in both sequences is the second term. Both of them equal 20.

Method

S1: Multiply by 2 starting with 10.

10*2 = 20

20*2 = 40

S2: Start at 24 and subtract 4

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

We're specified that:
