61/28+a=19/4a-11/7
Clear the fraction by multiplying by the lcd. The lcd for 28, 4, and 7 is 28 (Since 7 and 4 are factors of 28)
(6/28)·28=6/1 or 6
a·28=28a
(19/4)·28=19·7=133
(11/7)·28=11·4=44

6+28a=133a-44
Combine like terms:
6=105a-44
50=105a
Isolate the a: 50/105÷5=10/21
a=10/21 :)

You collect 140 total pieces of candy trick or treating and 35 of them are m&m's. What fraction of the candy is not m&m'
tekilochka [14]

\frac{3}{4} of the candy is not m&m's.

Step-by-step explanation:

Given,

Total pieces of candy = 140

Number of m&m's = 35

Fraction = \frac{Number\ of\ m&m}{Total\ pieces\ of\ candy}

Fraction = \frac{35}{140}

Both 35 and 140 are multiples of 7, therefore,

Fraction of m&m's = \frac{5}{20} = \frac{1}{4}

As the number of m&m's fraction and not m&m's fraction will make a total of 1, therefore

fraction of m&m's + fraction of not m&m's = 1

fraction of not m&m's = 1 - fraction of m&m's

fraction of not m&m's = 1-\frac{1}{4}=\frac{4-1}{4}

fraction of not m&m's = \frac{3}{4}

\frac{3}{4} of the candy is not m&m's.

If a quadratic function has x-intercepts at (-7,0) and 10,0), where would
madam [21]

Answer:

x = 1.5

Step-by-step explanation:

Since the axis of symmetry is between the 2 x intercepts, we can find it by finding the average of the x-coordinates of the 2 points.

(-7 + 10) / 2

3/2

= 1.5

So, the axis of symmetry is at x = 1.5
