Jill's fish weighs 8 times as much as her parakeet. Together, the pets weigh 63 ounces. How much does the fish weigh?

2 answers:

7 0

Let $x$ be the weight of her parakeet. From this, we know that her fish weighs $8x$ .

$8x + x = 63$
$9x = 63$
$x = 7$

Her fish weighs 7 x 8 ounces = 56 ounces.

Let x =the weight of the parakeet. 8x=weight of the fish. x+8x=63 <-weight of fish and parakeet together equals 63 ounces. SOLVE FOR X. 9x=63. /9 /9 x=7 <-- parakeet weighs 7 ounces. 8x= 8(7). 8x7= 56. the fish weighs 56 ounces.

Given: BD is a diameter m 1 = 100° m BC = 30° m AC = 60 110 200

KiRa [710]

Answer:

110°

Step-by-step explanation:

$m\angle 1 + m\angle 2 = 180\degree$

(linear pair angles)

$100\degree + m\angle 2 = 180\degree$

$m\angle 2 = 180\degree- 100\degree$

$m\angle 2 = 80\degree$

$\because m\widehat {AB} =m\angle 2$

(Measure of the minor arc is equal to the corresponding central angle)

$\therefore m\widehat {AB} = 80\degree$

$\because m\widehat {AC} =m\widehat {AB} +m\widehat {BC}$

(By arc sum property)

$\therefore m\widehat {AC} = 80\degree+30\degree$

$\huge \red {\boxed {\therefore m\widehat {AC} = 110\degree}}$

A parking garage allows users to park the first hour free and then charges $2.50 for each additional hour or fraction of an hour

Snowcat [4.5K]

The first hour is free, and the rest charges is $2.50

Let x be the time.

Let y be the total

Your equation will look like

When x < 2, y = 0

When x > 1, y = $2.50(x)

So:

1 < x < ∞ for hours, then equation will look like:

y = total amount

$2.50 is cost (remember that the first hour is for free, and so you subtract $2.50 from the total.

$2.50x - $2.50 = y should be your equation.

hope this helps

What is a linear equation in math?

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article.
Some of the examples of linear equations are 2x – 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x – y + z = 3.

$\frac{3^{2} * 3^{-5} }{4^{2} } = \frac{3^{-3} }{4^{-2} }$

$\frac{1}{3^{3} }$ ÷ $\frac{1}{4^{2} }$

$\frac{1}{27} * 16 = \frac{16}{27}$

My chemistry book is 8 years older than my Algebra book. In 6 years the chemistry book will be twice as old as the Algebra book.

4vir4ik [10]

Answer:

x + 14 = 2(x + 6)

x = 2

Step-by-step explanation:

Let

Algebra book age = x

Chemistry book age = x + 8

In 6 years time

Chemistry book age = x + 8 + 6

= x + 14

Algebra book age = x + 6

the chemistry book will be twice as old as the Algebra book.

x + 14 = 2(x+6)

x + 14 = 2x + 12

x - 2x = 12 - 14

- x = - 2

Divide both sides by -1

x = 2

Check:

Chemistry book age = x + 14

= 2 + 14

= 16

Algebra book age = x + 6

= 2 + 6

= 8
