Evaluate abc2 if a = −3, b = 6 and c = −8.

Answer:

In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match.

Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power. For example, 8xyz2 and −5xyz2 are like terms because they have the same variables and power while 3abc and 3ghi are unlike terms because they have different variables. Since the coefficient doesn't affect likeness, all

Answer:

unlike terms

Answer:

K - Constant of proportionality

Y/X = K

Step-by-step explanation:

Can’t see the graph but the first point can be calculated. If your first point is (100,78) that’s (x,y), your k = 78/100, $78 US dollars and 100 euros, thus the unit rate is 78/100 = 0.78/1 which means 0.78 dollars equals 1 euro.

Answer:

129:175

Step-by-step explanation:

Andy and Christopher are measuring a liquid solution using a graduated cylinder

Andy uses 3.5 liters of the liquid solution

3.5 liters to mililiters

= 3.5 ×1000

= 3500 mililiters

Christopher uses 2580 mililiters

Therefore the ratio of Christopher's measurement to Andy's measurement can be calculated as follows

= 2580/3500

= 129 : 175

Hence the ratio of Christopher's measurement to Andy's measurement is 129:175

Answer: 5t = 400-105

Step-by-step explanation:

Let t= Number of three–pointers Marissa has to average over the next 5 days to reach her goal. .

Goal = 400 three–pointers every week.

Marissa has already shot  = 105 three–pointers

Remaining shots to achieve target (5t) = Goal - (Marissa has already shot)

i.e. 5t = 400-105  (required equation)

⇒ 5t = 295

⇒ t = 59

hence, she need to make 59 shots per day for next 5 days.

Step-by-step explanation:

Answer: Cost of a side dish = $ 7

Cost of a roll = $1

Cost of prime rib = $21

Step-by-step explanation:

Let x = cost of a side dish , y= cost of a roll

Then, cost of a prime rib = 3x

Jackie's meal : prime rib, 2 side dishes, and a roll, it came to $36

i.e. 3x+2x +y = 36

⇒ 5x+y=36   (i)

Ted's meal : prime rib, 3 side dishes, and 2 rolls, it came to $44.

i.e. 3x+3x +2y = 44

⇒6x+2y=44

⇒ 3x+ y= 22   (ii)  [divide both sides by 2]

Subtract (ii) from (i), we get

2x= 14

⇒ x=7               [divide both sides by 2]

Put x=7 in (ii), 3(7)+y=22

⇒ 21+y=22

⇒  y =22-21

⇒ y= 1

So, cost of a side dish = $ 7

cost of a roll = $1

cost of prime rib = 3x $7 = $21

Answer:

The general rule for estimating is to look at the digit to the right of the digit you want to estimate. Estimating or rounding to the nearest whole number means looking at the digit to the right of the decimal. If you see a digit greater than 5, round up, and if it's less than 5, round down.

Step-by-step explanation:

Answer:

99*10^(-3)

Step-by-step explanation:

When you get a decimal you always have to have a negative when with powers of 10 and 99 is like the decimal 99.0 and if you move the decimal over 3 times you get 0.099

Answer:

y = 6.93

Step-by-step explanation:

Given the Vertex and ficuas of a parabola as :

Vertex (0,0) ; focus(0,2) ; depth = 5 inches

Width of parabolic heater at its widest point :

General equation of a parabola:

4p(x - h) = (y - k)²

(h, k) = Vertex

hence,

h =0 ; k = 0 ; p = 2 ; x = 5

(y - k)² = 4p(x - h)

(y - 0)² = 4*2(6 - 0)

(y-0)(y-0) = 8(6 - 0)

y² = 48 - 0

y² = 48

y = 6.928

y = 6.93

Answer:

Police officers, whether plain-clothed or uniformed, carry a variety of equipment with them on service calls. Police in uniform carry much more equipment than those in plain clothes, and members of special operations teams, such as SWAT and crowd-control units, carry even more, sometimes including full body armour complete with helmet, leg pads, and shield.

Answer:

-3 = x

Step-by-step explanation:

4 (2x + 3) = 4x + 24 + 6x – 6

8x + 12 = 10x + 18

12 = 2x + 18

-6 = 2x

-3 = x

Reasoning: Complementary angles always add to 90 degrees.

If angle 2 was x, then x+83 = 90 solves to x = 7

The measure of m∠2 is 7° due to the pair of angles being complementary.

The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.

Adjacent angles: Adjacent angles are the type of supplementary angles. Adjacent angles have a common side and vertex, for example, a corner point. Their points do not overlap in any way. In other terms, adjacent angles are pairs of two angles next to each other.

We have been given that the pair of angles as

m∠1 = 83°  and m∠2 = x

Here, the pairing of angles sums up to 90° then they are called complementary angles.

So x + 83 = 90°

⇒ x = 90° - 83°

⇒ x = 7°

Therefore, the value of m∠2 is 7°.

Answer:

7

Step-by-step explanation:

5x = 35

Divide both sides by 5

x = 7

Whenever you have an equation like this, you have to simply divide both sides by the coefficient.

Answer:

1-12x=-20-9x

-12x=-21-9x

-3x=-21

divide both sides by -3

Answer:

I believe it would be A: 60°.

Step-by-step explanation:

I suck at explaining stuff but since R is 60°, and theres 120° outside of the triangle, that implies T = 60°. Triangles equal 180° so

60° + 60° + S = 180°

S = 60°

Hope this helps

Answer:

The answer of the question is 60° which is option(A).

here,

let one be suppose angle a°

a°+ 120° = 180° {being straight angle}or, a° = 180° - 120°

or, a° = 60°

a° = 60°

Now,

Let angle S be s°

s°+60°+60° = 180°{ the sum of angle of triangle is 180°}

or, s° = 180° - 120°

or, s° = 60°

therefore, angle S is 60°
