Find x.
9x – 15=7x-1

Answers

Answer 1

Answer:

x=7

Step-by-step explanation:

First, add 15 to both sides (whatever you do to one side, do it to the other), this will help cancel out the -15 on the right side of the equation,  

so 9x-15+15=7x-1+15,      the 15 cancels out and we get 9x=7x+14

Now we want to simplify this further, lets subtract 7x from both sides,

9x-7x=7x-7x+14,     2x=14

Let's divide both sides by 2 because the 2 and x are held together by "multiplication" so we will break that bond with division and that will leave us with x.

2x/2=14/2

x=7

Our goal is to have a variable on one side and a number on the other, so that is why we are doing this. Also, notice that to solve this equation we were doing the reverse operation. For example, when we added 15 to both sides, we were performing the opposite of subtraction because we had a -15. Remember that variables are connected to numbers through multiplication, so 9x would be the same thing as 9*x

Translate (in terms of x) then solve the algebraic equation: Five times the sum of 6 and some number is 20. HELPPPPP PLEASE HELP I REALLY NEED HELP

Answers

Answer:

The answer is 5 ( 6 + x ) = 20

Step-by-step explanation:

Five times = You are multiplying 5 to a number(s)

Sum of 6 and some number = Sum means to add. You are adding 6 to an unknown number.

In terms of x = You do not know what you are adding 6 with. Therefore 6+x.

is 20 = The total is 20.

To solve:

5 ( 6 + x ) = 20

30 + 5x = 20  Use the distributive property and multiply 5 to the 6 and the x

-30 + 5x = -30   Subtract the 30 on both sides

5x = -10              The 30's would cancel each other out and this is what's left

5x/5 = -10 / 5           Divide 5 on both sides.

x = -2                        The 5 cancels each other on the left side.

x = -2                        Is your answer

Hope this helps!

5) It is known that ∠BAM and ∠CTX are complementary. If m∠BAM = x + 2 4 and m∠CTX = x + 11, then

solve for the value of x algebraically.

Answers

Answer:

x = [tex]27.5^{o}[/tex]

Step-by-step explanation:

complementary angles are two or more angles whose sum is equal to [tex]90^{o}[/tex].

Thus given that;

m<BAM = x + 24

m<CTX = x + 11

So that,

m<BAM + m<CTX = 90

⇒ (x + 24) + (x + 11) = 90

x + 24 + x + 11 = 90

2x + 35 = 90

2x = 90 - 35

2x = 55

x = [tex]\frac{55}{2}[/tex]

 = 27.5

The value of x is [tex]27.5^{o}[/tex].

So that,

m<BAM = x + 24

             = 27.5 +24

             = [tex]51.5^{o}[/tex]

m<CTX = x + 11

            = 27.5 + 11

           = [tex]38.5^{o}[/tex]

1.8 -0.4y = 2(1.1 - Y)

Answers

Answer:

y=0.25

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1.8−0.4y=2(1.1−y)

1.8+−0.4y=(2)(1.1)+(2)(−y)(Distribute)

1.8+−0.4y=2.2+−2y

−0.4y+1.8=−2y+2.2

Step 2: Add 2y to both sides.

−0.4y+1.8+2y=−2y+2.2+2y

1.6y+1.8=2.2

Step 3: Subtract 1.8 from both sides.

1.6y+1.8−1.8=2.2−1.8

1.6y=0.4

Step 4: Divide both sides by 1.6.

1.6y/1.6 = 0.4/1.6

Given that f(x) = x2 – 3x - 10 and g(x) = x – 5, find (f - g)(x) and express
the result in standard form.

Answers

Answer:

[tex](f-g)(x)= x^2-4x-5[/tex]

Step-by-step explanation:

We have the two functions:

[tex]f(x)=x^2-3x-10\text{ and } g(x)=x-5[/tex]

And we want to find (f-g)(x).

(f-g)(x) is equivalent to f(x)-g(x).

Therefore:

[tex]\begin{aligned} (f-g)(x)&=f(x)-g(x)\\ &=(x^2-3x-10)-(x-5)\end{aligned}[/tex]

Simplify:

[tex]\begin{aligned} &=x^2-3x-10-x+5 \\ &=(x^2)+(-3x-x)+(-10+5) \\ &=x^2-4x-5\end{aligned}[/tex]

Therefore:

[tex](f-g)(x)= x^2-4x-5[/tex]

7. The graph to the right represents the distance (y) Kirk has walked after x seconds.
a. What is the slope-intercept equation for the graph?
b. Predict how far Kirk will have walked after 72 seconds.

Answers

Answer:

a). y = 1.6x

b). Distance traveled = 115.2 feet

Step-by-step explanation:

From the graph attached,

A). Distance traveled by Kirk ∝ Duration of walk

    D ∝ t

    D = kt

    Or y = kx

    Since a point (5, 8) lies on the line given in the graph,

    8 = 5k

    k = [tex]\frac{8}{5}[/tex] = 1.6

    Therefore, equation will be,

    y = 1.6x

B). We have to find the distance walked after 72 seconds.

    By putting x = 72 seconds

    y = 1.6 × 72

       = 115.2 feet

    Distance traveled by Kirk = 115.2 feet

The teacher asked 4 students to measure 4 different objects. Here are the results
Which student had the greatest percent error?

Answers

Answer:

Student 3 had the greatest percentage error.

Step-by-step explanation:

Student 1

Actual length = 50in

Measured length = 49in

Error = 50 - 49 = 1

Error% = 1/50 × 100

= 1 × 2

= 2%

Student 2

Actual length = 100cm

Measured length = 110cm

Error = 100 - 110 = 10

Error% = 10/100 × 100

= 10 × 1

= 10%

Student 3

Actual length = 2cm

Measured length = 2.5cm

Error = 2 - 2.5 = 0.5

Error% = 0.5/2 × 100

= 0.5 × 50

= 25%

Student 4

Actual length = 10ft

Measured length = 9½ft

Error = 10 - 9½ = ½

Error% = ½/10 × 100

= ½ × 10

= 1 × 5

= 5%
