Solve for the variable!! Please

Answers

Answer:

[tex]\huge\boxed{t=3}[/tex]

Step-by-step explanation:

[tex]-5(t+3)=-30[/tex]

METHOD 1:

[tex]-5(t+3)=-30[/tex]    divide both sides by (-5)

[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]

[tex]t+3=6[/tex]       subtract 3 from both sides

[tex]t+3-3=6-3\\t=3[/tex]

METHOD 2:

[tex]-5(t+3)=-30[/tex]       use the distributive property a(b + c) = ab + ac

[tex](-5)(t)+(-5)(3)=-30[/tex]

[tex]-5t-15=-30[/tex]     add 15 to both sides

[tex]-5t-15+15=-30+15[/tex]

[tex]-5t=-15[/tex]         divide both sides by (-5)

[tex]\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3[/tex]

lydia wants to purchase guitar lessons she sees a sign that gives the price is 47 guitar lessons and 11 guitar lessons write a linear equation to find the total cost c for d lessons

Answers

Answer:

c = 58x

Step-by-step explanation:

A linear equation is an equation in the form of f(x) = mx + c. Where m is the slope and c is the intercept.

Let the price of one guitar lessons be x, then 47guitars will be 47x and 11 guitar lessons will be 11x. All together will be 47x + 11x = 58x.

Thus, the total cost, c, is

Graph the following system of inequalities.
y>1/3x-2
y <-4x-2

Answers

Graph-X represents the given set of inequalities.

What is inequality?

"An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions."

Given two inequalities are:

1. y > (1/3)x - 2

If we compare it with the slope-intercept form of a line, then:

Slope = 1/3, y-intercept = - 2

Therefore, the line cuts the y-axis at x = - 2.

Here, the greater than sign indicates that the graph would be shaded down.

2. y < - 4x - 2

If we compare it with the slope-intercept form of a line, then:

Slope = - 4, y-intercept = - 2

Therefore, the line cuts the y-axis at x = - 2.

Here, the less than sign indicates that the graph would be shaded up.

Therefore, Graph-X represents the given set of inequalities.

Given that u, = 1,
a) find u,
b) find uz
c) find us

Answers

Answer:

see solution below

Step-by-step explanation:

Correct question

A sequence is defined by the term-to-term rule

Un+1 = u. + 3

Given that u1 = 1,

a) find u2

b) find u3

c) find u5

a) Given the recursive formula;

Un+1 = un + 3

When n = 1;

U1+1 = U1 + 3

U2 = U1 + 3

U2 = 1 + 3

U2 = 4

b) U3 = U2 + 3

U3 = 4 + 3

U3 =7

c) U4 = U3 + 3

U4 = 7+3

U4 = 10

U5 = U4 + 3

U5 = 10 + 3

U5 = 13

Note that the question was assumed. The same calculation can be employed for nay other term

One of the angles of a triangle is 8 deg more than 5 times another angle. If the third angle is 4 deg larger than the difference of the first two angles, find the angles.

Answers

Answer:

[tex]16^\circ, 88^\circ, 76^\circ[/tex]

Step-by-step explanation:

Given a triangle.

One of the angles is [tex]8^\circ[/tex] more than 5 times of one angle.

Third angle is [tex]4^\circ[/tex] more than the difference of two angles.

To find:

The angles.

Solution:

Let the first angle = [tex]x^\circ[/tex]

As per question statement, second angle = 5[tex]x^\circ[/tex] + [tex]8^\circ[/tex]

And third angle = 5[tex]x^\circ[/tex] + [tex]8^\circ[/tex] - [tex]x^\circ[/tex] + [tex]4^\circ[/tex] = [tex](4x+12)^\circ[/tex]

Using triangle sum property that the sum of all the internal angles of a triangle is always equal to [tex]180^\circ[/tex].

[tex]x+5x+8+4x+12 = 180\\\Rightarrow 10x+20=180\\\Rightarrow 10x = 160\\\Rightarrow x = 16[/tex]

Therefore, the first angle = [tex]x^\circ = 16^\circ[/tex]

The second angle = [tex]5x+8 = 5 \times 16 + 8 = 80+8 = 88^\circ[/tex]

The third angle = [tex]4x+12 = 4\times 16 + 12 = 76^\circ[/tex]

Therefore, the angles are [tex]16^\circ, 88^\circ, 76^\circ[/tex].

(a) Type an equation and (b) solve. Type the answers in the spaces provided. In the basketball championship game, the Falcons had three fewer than twice as many Bears players. If the Falcons had 11 players, how many players were on the Bears? (Use b as the variable.) (a) (b) Bears:

Answers

Answer:

There were 7 players on the Bears

Step-by-step explanation:

Given

[tex]a = falcons[/tex]

[tex]b = bears[/tex]

We have that:

[tex]a = 11[/tex]

and also:

[tex]a = 2b - 3[/tex] --- 3 fewer than twice a

Required

Solve for b

Substitute 11 for a in [tex]a = 2b - 3[/tex]

[tex]11 = 2b - 3[/tex]

Add 3 to both sides

[tex]3+11 = 2b - 3+3[/tex]

[tex]3+11 = 2b[/tex]

[tex]14 = 2b[/tex]

Divide both sides by 2

[tex]\frac{14}{2} = \frac{2b}{2}[/tex]

[tex]7 = b[/tex]

[tex]b = 7[/tex]

Hence, there were 7 players on the Bears

Okay so I have no clue what to do on these problems lol. Can someone help explain it please? Thank you

Answers

Answer:

you use the Pythagorean theorem (a^2 +b^2 = c^2)

a^2 +17^2 = 19^2

a^2 + 289 = 361

a^2 = 72

a = (square root)72

5^2 + 13^2 = c^2

25 + 169 = c^2

194 = c^2

c= (square root)194

a^2 + 10^2 = 20^2

a^2 + 100 = 400

a^2 = 300

a = (square root) 300

5^2 + 14^2 = c^2

25 + 196 = c^2

221 = c^2

c= (square root) 221

−3x+7=−x+1

Step 2: Add x to both sides.

−3x+7+x=−x+1+x
