how to solve the following quadratic equations; 2L, m, o, 3a and g

Answer: 4.5

Step-by-step explanation:

To evaluate ab - 0.50, we want to plug in the given values for a and b and then solve.

(1)(5)-0.5                       [multiply]

5-0.5                             [subtract]

4.5

After plugging in the values of a and b, we found that the solution is 4.5.

Answer:

20

Step-by-step explanation:

x + 84 = 4x

These are equal because they're vertical angles. Now, let's subtract x from both sides.

84 = 3x

Divide both sides by 3

28 = x

x + 84 = 28 + 84 = 112 degrees

Answer:

1.57

Step-by-step explanation:

9/11+3/4

=1.56818181818181.....

=1.57

Answer:

69/44

Step-by-step explanation:

=(9x4) + (3x11)

___________

       11x4

=69/44 or 1 25/44

Answer:

C

Step-by-step explanation:

2x +4 > 16

If you plug in 6 where the x is, and multiply 2 by 6, you get 12. Add 4 to 12 to get 16. If x is 6 it equals 16, so if x > 6 the answer will be more than 16.

answer: x=3

you divide both side by 2

Answer:

I think ot a it been awhile sense I did algebra

Answer:

X= 19

Step-by-step explanation:

If you take 4 away from 19, it equals 15, the perimeter is all sides of the square. Which is 4 sides, 15 x 4 = 60 or 15+15+15+15. The formula for perimeter is all the sides added together.

Answer:

Fraction: 8 [tex]\frac{11}{20}[/tex]

Decimal: 8.55

Step-by-step explanation:

8 11/20 is the answer because:

1) Since 8 is the whole number, 8 wouldn't be part of the fraction

2) The numerator is the top number in the fraction, so 11 is at the top since 11 is the numerator

3) The denominator is the bottom number in the fraction, so 20 is at the top since 20 is the denominator

8.55 is the answer because:

1) Since 8 is the whole number, 8 would be in front of the decimal point

2) When you multiply the fractions, you have to multiply until you get a hundred. Therefore, 20*5 = 100 and 11*5 = 55

Hope this helps!

Answer:

True the absolute value is how many digits away the number is from zero.

Step-by-step explanation:

an equation in slope intercept form is

y=mx+b

Answer:

y=mxb,

cuz the mx stands for slope, and the b stands for y-intercept

I'm sorry if this is incorrect, but I think the answer is [tex]-2, \sqrt{5}, 4, 3^2[/tex]

Explanation: A negative number will always be the least. 3 squared is actually 3*3 and that would be 9. The square root of 5 is 2.2360679775 which is less than 4 so that would go in the second place. I hope this makes sense! :)

Answer:

Below in bold.

Step-by-step explanation:

You do not say if the interest is simple or compound.

Simple Interest: I = PRT/100

= (8600* 2.6 * 4)/ 100

= $894.40.

Compound Interest:- amount after 4 years

= 8600(1 + 0.026)^4

= $9529.89

So the compound interest

= 9529.89 - 8600

= $929.89.

Answer:

-x² + 2x + 8

Step-by-step explanation:

Essentially we need to subtract g(x) from f(x):

(f - g)(x) = f(x) - g(x) = (2x + 1) - (x² - 7)

Distribute the negative:

(2x + 1) - x² - (-7) = (2x + 1) - x² + 7

Combine like terms:

2x + 1 - x² + 7

-x² + 2x + 8

Thus, the answer is -x² + 2x + 8.

the length of sides AB of the triangle is sum of all sides..

Answer:

Step-by-step explanation:

Let us take this one by one. One color can pair with three colors.

Green = Maroon, Blue, Wheat = GM, GB, GW

Maroon = Green, Blue, Wheat = MG, MB, MW

Blue = Green, Maroon, Wheat = BG, BM, BW

Wheat = Green, Maroon, Blue = WG, WM, WB

So the combinations are:

GM, GB, GW, MG, MB, MW, BG, BM, BW, WG, WM, WB

Which is letter B.

Answer:

Corresponding angles

Step-by-step explanation:

Corresponding angles are formed when two lines are crossed by another line (which is called the Transversal) So , the angles in matching corners are called corresponding angles.

Answer:

they all fit correctly

At starting hot-air balloon starts 6 feet.

So, at t = 0 , h = 6 feet.

Now, distance travelled per minute is 20 feet.

So, extra distance travelled in t minutes is 20t feet.

Now,

Total height = Staring height + increase in height w.r.t time.

h = 6 + 20t

Therefore, the height h in feet as a function of time t in minutes is h = 6 + 20t .

Hence, this is the required solution.

Answer:

Frequency

Step-by-step explanation:

"A dot plot is a visual display in which each piece of data is represented by a dot above a number line, showing the frequency of each data value. The total number of dots in the plot is the total number of values in the data set. The data points must all be in the same units."

Answer:

n = m - a

Step-by-step explanation:

Given that:

The expression of the formula  a = m - n

where;

a = actual cost of an item

m = original price

n = amount of coupon in dollars

The objective is to solve for the amount of the coupon.

In order to determine the amount of the coupon, we need to make n which is the amount of coupons in dollars the subject of the formula from the given expression.

So if a = m - n

a + n = m

n = m - a

Answer:

13.5 ounces of silver is worth $272.16

Step-by-step explanation:

since it is $20.16 per ounce, simply multiply 20.16 and 13.5 to get 272.16

Step-by-step explanation:

Times 20.16 by 13.5 and you will get 272.16

Answer:

x=3

Step-by-step explanation:

subtract 5x from 7x

subtract 4 from 10

divide 2x and 6 by 2

Answer:

x=3

Step-by-step explanation:

7x +4 =5x +10

7x - 5x =10 - 4

2x =6

x=6 :2

x=3

7 ×3 +4 =5 ×3 +10

21 +4 =15 +10

25 =25
