You said 9x + y = 10

Subtract 9x
from each side: y = -9x + 10

Graph the solution to the following linear inequality in the coordinate plane. 5 x - y > -3

Svetlanka [38]

Given:

The inequality is:

$5x-y>-3$

To find:

The graph for the given linear inequality in the coordinate plane.

Solution:

We have,

$5x-y>-3$

The related equation for this inequality is:

$5x-y=-3$

The table of values is:

x y

0 3

-1 -2

Plot the points (0,3) and (-1,-2) on a coordinate plane and connect them by a dotted straight line because the sign of inequality is >.

Check the given inequality for (0,0).

$5(0)-(0)>-3$

$0>-3$

This statement is true. So, the shaded area of the given inequality is towards the origin.

Therefore, the required graph is shown below.

A painter needs to paint the bottom of a circular pool. The pool has a radius of 30 feet. A store sells 5-gallon cans of paint.

DIA [1.3K]

Answer:

Step-by-step explanation:

the area of the radius 30 is 2827 and since 1 bucket can cover 1800 we will only need 2 buckets because we need a total of 2827 and 1 bucket covers 1800 so 2 buckets will cover 3600.

Answer:

The number of comic books did they have in all = 56

Step-by-step explanation:

The ratio of comics with Susan : Abe = 3 : 5

Let us assume the common factor on this ratio = m

So, the number of comics Susan has = 3 m

The number of comics Abe has = 5 m

Also, given: Abe had 14 more comic books than Susan

So, the number of comics Abe had = 14 + 3 m

⇒ 5 m = 3 m + 14

or, 2 m = 14, or m = 7

So, the number of books Susan has = 3 m = 3 x 7 = 21 books

The number of books Abe has = 5 m = 5 x 7 = 35

So, the book they have in all = 21 + 35 = 56

Lostsunrise [7]

William needs 102.6 fencing in all because 76.9 plus 25.7 equals 102.6, hope this helps!

2. Find each product in lowest terms.

defon

$\textsf {Part (a) :}$

$\implies \mathsf {\frac{3}{4} \times 1\frac{7}{9}}$

$\implies \mathsf {\frac{3}{4} \times \frac{16}{9}}$

$\implies \mathsf {\frac{4}{3} = 1\frac{1}{3}}$

$\textsf {Part (b) :}$

$\implies \mathsf {4\frac{4}{7} \times 3\frac{1}{4}}$

$\implies \mathsf {\frac{32}{7} \times \frac{13}{4}}$

$\implies \mathsf {\frac{104}{7} = 14\frac{6}{7}}$

$\textsf {Part (c) :}$

$\implies \mathsf {1\frac{7}{8} \times 2\frac{1}{4}}$

$\implies \mathsf {\frac{15}{8} \times \frac{9}{4}}$

$\implies \mathsf {\frac{135}{32} = 4\frac{7}{32}}$
