Fellow brains pls help.... Is this true or false?

Answer:

-96

Step-by-step explanation:

multiply both sides by 16

Answer:

x = 3 and x = [tex]\frac{9}{2}[/tex]

Step-by-step explanation:

(a)

2(5x - 3) = 24 ( divide both sides by 2 )

5x - 3 = 12 ( add 3 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

(b)

5(2x + 1) = 50 ( divide both sides by 5 )

2x + 1 = 10 ( subtract 1 from both sides )

2x = 9 ( divide both sides by 2 )

x = [tex]\frac{9}{2}[/tex]

Step-by-step explanation:

The equation that represents the distance (d) Allison has left to drive after h hours is given by: Option C: d = 380 - 60h

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

We're given that:

In 1 hour, she averagely covers 60 miles.

In h hours, she averagely covers [tex]60 \times h[/tex] hours

d = distance remaining for her to reach to her grandmother's home after h hours of driving

d = Total distance - distance traveled in h hours

d = 380 - 60×h

(sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together, so 60×h can be simply written 60h)

Thus, the equation that represents the distance (d) Allison has left to drive after h hours is given by: Option C: d = 380 - 60h

Answer:

x = 12

y = 8

Step-by-step explanation:

to solve for x you would set up your equation:

4x - 3 = 45

then solve using algebra:

4x - 3 = 45

4x = 48

x = 12

to solve for y set up your equation as:

11y + 6 = 94

TO GET 94: you will need to subtract 41 and 45 from 180 to get 94.

(each triangle equals 180 and we need the 3rd measure)

solve the equation:

11y + 6 = 94

11y = 88

y = 8

Answer:

[tex]\huge\boxed{x = 8}[/tex]

Step-by-step explanation:

In order to solve for x, we need to note a few angle relationships here.

Using these rules, we can start to figure out that the angle [tex]7x+3[/tex] is going to be congruent to the angle [tex]3x+35[/tex]. Since the angle measures will be the same, that means the value of x will also be the same. Therefore, we can set the two equations equal to each other and solve for x.

Answer: −  1 ^2  −  4 1

Answer:

12.6

Step-by-step explanation:

Given

with reference angle 57°

perpendicular (p) = y

hypotenuse (h) = 15

Now

sin 57° = p / h

0.84 = y / 15

y = 0.84 * 15

y = 12.6

Step-by-step explanation:

Given:

The function is

[tex]f(x)=\left(\dfrac{1}{3}\right)^x[/tex]

To find:

The missing values for a, b, and c in the given table.

Solution:

We have,

[tex]f(x)=\left(\dfrac{1}{3}\right)^x[/tex]

At x=-2,

[tex]f(-2)=\left(\dfrac{1}{3}\right)^{-2}[/tex]

[tex]a=\left(3\right)^{2}[/tex]         [tex]\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right][/tex]

[tex]a=9[/tex]

At x=-1,

[tex]f(-1)=\left(\dfrac{1}{3}\right)^{-1}[/tex]

[tex]b=\left(3\right)^{1}[/tex]         [tex]\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right][/tex]

[tex]b=3[/tex]

At x=0,

[tex]f(0)=\left(\dfrac{1}{3}\right)^{0}[/tex]

[tex]c=1[/tex]         [tex]\left[\because a^0=1, a\neq 0\right][/tex]

Therefore, the missing values of a,b and c are 9, 3, and 1 respectively.

Answer:

250 + 0.05 (1500)

A linear function is a function that changes at a constant rate.

The given parameters are:

A linear function is represented as:

[tex]C(x) = b + mx[/tex]

Where:

So, we have:

[tex]C(x) = 250 + 5\% \times x[/tex]

Express 5% as decimal

[tex]C(x) = 250 + 0.05 \times x[/tex]

[tex]C(x) = 250 + 0.05x[/tex]

On a sale of $1500, the equation becomes

[tex]C(x) = 250 + 0.05 \times 1500[/tex]

[tex]C(x) = 325[/tex]

Hence. David would make $325 if he made $1500 in sales, and he would make 250 + 0.05x if he made $x in sales

Answer:

1.5625

Step-by-step explanation:

Find the ratio (r) between adjacent members: 50,25,12.5,6.25,3.125

a_2/a_1=25/50=0.5

a_3/a_2=12.5/25=0.5

a_4/a_3=6.25/12.5=0.5

a_5/a_4=3.125/6.25=0.5

The ration (r) between every two adjacent members of the series is constant and equal to 0.5 thus:

a_6 =a_1×(^r6-1)  =a_1×r^5 =50×0.5^5 =1.5625

I think it's the third 4 ( а² + 2а ) + 9

Answer:

B x = 7

Step-by-step explanation:

You know based on the ratio that it's being scaled by 4 times because the one side 4 is 16 in the bigger pentagon.

So if you go the side that matches the one you need to solve, it's 2.5.

2.5 times 4 = 10 so that bigger pentagon side should equal 10.

The equation x-3 = 10

which means x is 7
