Explain how solving 8+2 can help you solve 80+20

Mathematics

Because 8+2=10, and when both values are scaled by 10, the equation 10 x 10 results in 100.

Anya graphed the line (y−2)=3(x−1) on the coordinate grid. A coordinate plane with a line passing through the points, (negative
Inessa [12570]

Answer:

Anya's line has a slope of m = 3

Step-by-step explanation:

Explanation:-

Anya created a graph representing the line

                             (y−2)=3(x−1)

From this, we can deduce that the slope-intercept representation is

                                y = mx +c

Now by rewriting Anya's line

                           y−2=3(x−1)

            ⇒            y - 2 = 3x - 3

          ⇒             y = 3x - 3 + 2

         ⇒              y = 3 x - 1

<pBy comparing this with the slope-intercept structure<p                         y = mx +c<pwe conclude that Anya's slope is m = 3, and y-intercept is C = -1

Dan gets pic 'n mix when at the cinema and makes his bag up with 3 types of sweet. He picks 3 times as many cola bottles as smar
Leona [12618]

Response:

1/6

Detailed explanation:

Let

c -----> the count of cola bottles chosen by Dan

s -----> the count of smarties selected by Dan

m -----> the count of marshmallows selected by Dan

we have

c=3s -----> A equation

m=2s -----> B equation

we understand that

To determine the fraction of the sweet bag that consists of smarties, we must divide the number of smarties by the total amount of sweets

The overall number of sweets is calculated as

(c+s+m)

substituting equations A and B into the total sweets

(3s+s+2s) =6s

Calculate the fraction

s/6s

Reduce it

1/6

The angle by which AB turns clockwise about point B to coincide with BC is ? degrees. If from point B, a point E is drawn direc
Zina [12379]
A) AB rotates clockwise to align with BC

= ABD + DBC

= 33.3° + 30.6°

= 63.9°


b) If E is positioned directly opposite C.

EBC forms a straight line, thus the angle sums to 180°

ABE + ABD + DBC = 180°

ABE + 33.3° + 30.6° = 180°

ABE + 63.9° = 180°

ABE = 180 - 63.1

ABE = 116.9°
Hope this clarifies things.

The bus routes in a city run on average every 15 minutes. The route times can vary by three minutes. Which absolute value equati
AnnZ [12381]

Response:

Max = 18\ mins

Min = 12\ mins

Step-by-step explanation:

Information given:

Time = 15\ mins

Variation = 3\ mins

Objective:

Calculate the maximum and minimum values

The max value is found as follows:

Max = Time + Variation

Max = 15\ mins + 3\ mins

Max = 18\ mins

The min value is identified as follows:

Min = Time - Variation

Min = 15\ mins - 3\ mins

Min = 12\ mins

After a (not very successful) trick or treating round, Candice has 15 Tootsie rolls and 9 Twizzlers in her pillow case. Her moth
tester [12383]

Solution:

There are 4 ways.

Detailed explanation:

Candice has a total of 15 + 9 = 24 candies. Since she has three younger brothers, and 24 can be divided by 3 (24/3 = 8). Both 15 and 9 can also be divided by 3 (15/3 = 5 and 9/3 = 3).

- She can distribute 5 tootsie rolls to each brother.

- She can provide 3 twizzlers to each brother.

- She can give each brother 5 tootsie rolls and 3 twizzlers (if she decides to share all her candies).

- She can give them one of each type of candy, leaving her with 12 tootsie rolls and 6 twizzlers (this would be the best option if she wants to keep some for herself).

I see four methods to accomplish this, and two methods remain after her mother instructs her to share at least one of each candy type with all three brothers.
