Answer: She has 480 pieces of candy left after Halloween (option a ).

Step-by-step explanation:

Hi, to solve this problem we have to analyze the information given:

Candy available: six 100-piece bags

Number of children: 20

Pieces of candy for each child: 6

So, we have to calculate the total amount of candy available by multiplying the pieces of candy that each bag has (100) by the number of bags(6)

100 x 6 = 600

Then, we have to multiply the number of children (20) by the number of pieces of candy that each one receives (6) and then subtract that number to the number of pieces of candy available.

20x 6 = 120

600 -120 = 480

She has 480 pieces of candy left after Halloween (option a ).

4 + 6x + 5 = 7x Could someone help me? Thanks :) And could you also show how u did it

Answer:

x=9

Step-by-step explanation:

combine like terms

$4+6x+5=7x$

4+5=9

9+6x=7x

to get 6x with 7x subtract 6x from both sides as its positive

6x-6x=0

7x-6x=x

9=x

x=9

a class has 60 students.Given that 85% passed a science test. Find the number of students who failed and then convert o %

Vanyuwa [196]

Given:

Total students = 60

Student passed = 85%

To find:

The number of students who failed and then convert it in %.

Solution:

We have,

Number of passed student = 85% of Total students

= $\dfrac{85}{100}\times 60$

= $51$

So, number of passes students is 51.

Number of students who failed = Total students - Passes students

= $60-51$

= $9$

So, number of students who failed is 9.

$\text{Fail}\%=\dfrac{\text{Failed students}}{\text{Total students}}\times 100$

$\text{Fail}\%=\dfrac{9}{60}\times 100$

$\text{Fail}\%=15$

Therefore, 15% students fail in the test.

Put the following equation of a line into slope-intercept form, simplifying all

soldier1979 [14.2K]

Answer: y = 2x - 2

Explanation: The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Subtract 2x from both sides of the equation.
-y = 2 - 2x
Multiply each term in -y = 2 - 2x by -1
(-y) . -1 = 2 . -1 + (-2x) . -1
Multiply (-y) . -1
Multiply -1 by -1
Multiply y by 1
y = 2 . -1 + (-2x) . -1
Simplify each term
Multiply 2 by -1
y = -2 + (-2x) . -1
Multiply -1 by -2
y = -2 + 2x
Reorder -2 and 2x
y = 2x - 2

A rectangular lawn is twice as long as its breadth and its perimeter is 90 m.

Nina [5.8K]

Answer: length = 30, breadth = 15

length = l
breadth = b

l = 2b

2b + b + 2b + b = 90
6b = 90
b = 15

l = 2b
l = 2(15)
length = 30

b = 15
breadth = 15
