**Answer:**

x = 4

**Step-by-step explanation:**

5x-4=16

Add 4 to both sides of the equation.

5x = 20

Divide both sides by 5.

x = 4

**Answer:**

x=4

**Step-by-step explanation:**

You first add 4 to both sides and get 5x=20. Then you divide both sides by 5 to isolate the x and get x=4.

Hope this helped :)

After that incident, the Civil defense team decided to buy new trucks with ladders higher than 100 feet. They found 2 different trucks with the same height of ladders. The first truck costs $145,000 and will cost $0.31 per mile traveled based on the current gas prices. The second truck will cost $160,000 but gets better gas mileage, costing $0.27 per mile. They need to decide which truck is the best deal.

Answer:

the first truck

Step-by-step explanation:

the cost difference between the first truck and the second truck = $160,000-$145,000 = $15,000

the difference of gas cost between the first truck and the second truck = $0.31 - $0.26= $0.05 per mile.

so,

I think, this is a very significant number of truck cost compared with gas cost

for the best deal, the first truck is the best choice.

You buy a car for $16,000. It will decrease in value by 10% each year. How much will it be worth after 4 years?

Answer: 9,600

Step-by-step explanation:

I could possibly did wrong but I shall explain this none the less. I first knew that 10% of 16,000 was 1,600. So then I just timed that by four getting 6,400. I then did 16,000-6,400 getting $9,600. Sorry if I’m wrong

**Answer:**

$9600

**Step-by-step explanation:**

10% of 16,000 = 1600

1600*4= 6400

16,000-6,400

= 9600

how to solve y=-5/2x+4, Y=-1 using substitution

(i need the steps not just the answer)

**Answer:**

**Step-by-step explanation:**

- Since y = -1, we will substitute the y variable in the equation for -1.

-1 = -5/2x + 4

- Take away 4 from both sides in order to find out what x equals so we can substitute it.

5 = -5/2x

- turn it into a positive by multiplying each side by -1.

-1(-5 = -5/2x) =

5 = 5/2x

- Divide each side by 5.

1 = 1/2x

- Multiple both sides by 2.

2 = x

- Substitute the variables.

x = 2

y = -1

-1 = -5/2(2) + 4

A. 2(a + b)

B. 2 + ab

C. 2ab

D. 2(a/b)

**Answer:**

Option A

**Step-by-step explanation:**

That is your answer

**Answer:**

**a) 2(a+b)**

**Step-by-step explanation:**

the sum of 2 numbers (or more) is always addition

so the sum of a and b would be (a+b)

then, 2 times of a and b;

2(a+b)

^the times sign between the bracket and the 2 isnt needed, whenever there is a bracket and a number next to it, it is automatically a multiplication.

What is the axis of symmetry of h(x) = –2x2 + 12x – 3?

a. x = –15

b. x = –3

c. x = 3

d. x = 15

D If it’s not D than A sorry if I’m wrong

We will see that the** axis of symmetry** is x = 3, so the correct option is c.

The **axis of symmetry **is a line of the form x = a, such that it divides the **parabola **in two halves.

Particularly, the **axis of symmetry **passes through the **vertex**, so the x-value of the **vertex **is equal to the value of the axis.

Then we only need to find the x-value of the **vertex**, remember that for a **quadratic**:

[tex]y = a*x^2 + b*x + c[/tex]

The **vertex **is at:

[tex]x = -b/2a[/tex]

Then in our case, the **vertex **is at:

[tex]x = -12/(2*-2) = -12/-4 = 3[/tex]

So the **axis of symmetry** is x = 3, then the correct option is C.

Can you conclude from the figure that ABC is similar to DEF? Explain.

**Answer:**

Yes, we can conclude that Triangle ABC is similar to triangle DEF because the measures of the 3 angles of both triangles are congruent.

**Step-by-step explanation:**

We have the measure of 2 angles from both triangles, and we know that triangles have 180°, so we can solve for the measure of the third angle for both triangles.

Triangle ABC:

Measure of angle A= 60°

Measure of angle C= 40°

Measure of angle B = 180°- (measure of angle A + measure of angle C) = 180° - (60° + 40°) = 80°

Triangle DEF

Measure of angle E= 80°

Measure of angle F= 40°

Measure of angle D= 180° - (measure of angle E + measure of angle F) = 180° - (80° + 40°) = 60°

The measures of the angles in Triangle ABC are: 60°, 40°, and 80°.

The measures of the angles in Triangle DEF are: 60°, 40°, and 80°.

Since the measure of 3 angles of the two triangles are the same, we know that the two triangles are similar.
