Which of the sets shown includes of set Z that are both odd numbers and multiples of 5

1 answer:

8 0

None of the above because no multiples of 5 have negative numbers.moreover b,c,d contains a even number except a which is also a negative number

In an ordered pair,the x-coordinate represents the number of hexagons and the y-coordinate represents the total number of sides.

Novosadov [1.4K]

The y-coordinate would be 42.

Hexagons have 6 sides. The x-coordinate is the number of hexagons; since our x-coordinate is 7, that means 7 hexagons.

The y-coordinate is the total number of sides. 7 hexagons * 6 sides per hexagon = 42 sides.

Which number line represents the solutions to |x – 5| = 1? A number line from negative 7 to 7 in increments of 1. Two points, on

pochemuha

Answer:

Two points, one at 4 and one at 6.

Step-by-step explanation:

Equations with absolute value

The absolute value of a number x denoted as |x| is a number with the same magnitude with a positive sign. When we know the result of an absolute value, we cannot know if the original number is positive or negative.

If |x| = a, a>=0, then x=a or x=-a

The equation to solve is |x – 5| = 1. If we apply the above criteria, then

x-5=1 or x-5=-1

Which gives us two possible solutions for x

x=6

x=4

The correct answer is

Two points, one at 4 and one at 6.

Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project.in feet how much board was left?

guapka [62]

$\frac{5}{8} \text{ feet board is left }$

Solution:

Given that, Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project

To find: Board that was left

From given,

$\text{Total length of board } =\frac{7}{8} \text{ feet }$

$\text{Foot that was cut off } = \frac{1}{4} \text{ feet }$

Remaining feet of board is found by finding the difference between total length of board and foot that was cut off

$\text{Reamining board } = \text{Total length of board - feet of board that was cut off}\\$

Substituting the values we get,

$\text{Remaining board } = \frac{7}{8} - \frac{1}{4}\\\\\text{Remaining board } =\frac{7}{8} - \frac{1 \times 2}{4 \times 2}\\\\\text{Remaining board } =\frac{7}{8} -\frac{2}{8} = \frac{7-2}{8}\\\\\text{Remaining board } =\frac{5}{8}$

Thus $\frac{5}{8}$ feet board is left

If 3 pistachio and 1 walnut weigh the same as 10 peanuts, and 1 pistachio and 6 peanuts weigh the same as 1 walnut, how many pea

yuradex [85]

Answer:

Step-by-step explanation:

We need to translate all these statements to equations.

First of all, let P be the pistachios, W the walnuts and N the peanuts.

The first statement "3 pistachio and 1 walnut weigh the same as 10 peanuts" can be represented as:

3 P + 1 W = 10 N

The second statement "1 pistachio and 6 peanuts weigh the same as 1 walnut" can be represented as:

1 P + 6 N = 1 W

If we notice, both equations have a similar term: 1 W. The second gives us the equivalence to the weight of 1 walnut, whereas in the first we have the weight of 1 walnut as an unknown variable. Lets replace it!

3 P + 1 W = 10 P

3 P + (1 P + 6 N) = 10 P

4 P + 6 N = 10 P

We now need to sum (-4P) in both sides to eliminate the 4 P on the left:

4 P + 6 N - 4P = 10 P - 4 P

6 N = 6 P

Dividing both sides by 6:

N = P

Now we need an equation that relates walnuts to peanuts. Lets replace N=P on our firts equation:

3 P + 1 W = 10 P

3 N + 1 W = 10 N

Summing (-3 N) in both sides:

3 N + 1 W - 3N = 10 N - 3N

1 W = 7 N

So, 1 walnut weights the same that 7 peanuts
