Step-by-step explanation:

The mean number of siblings:

Solve the system of equations using the substitution method. 2x+y=8
y=x-1

Answers

Answer:

x=3

Step-by-step explanation:

If we know that y=x-1, we can just substitute it and replace y with (x-1)

so 2x+y=8 becomes:

2x+(x-1)=8 and we simplify that into:

3x-1=8, add 1 on both sides to make it:

3x=9, divide 3 on both sides

x=3

A company makes 140 bags.
41 of the bags have buttons but no zips.
39 of the bags have zips but no buttons.
49 of the bags have neither zips nor buttons.
How many bags have zips on them?

Answers

The number of bags that have zips on them is 50.

Calculation of the number of bags:

Since there is 140 bags out of which  39 bags contain zips but have no buttons. Also, we assume that the remaining 11 bags should both have zips and buttons

So, here the total no of bags should be

= 39 + 11

= 50

So the number of bags that have zips on them is 50.

3.- Doña Queta cosechó zanahorias de su huerto, al contar las zanahorias se dio cuenta de que había cosechado el 230% de zanahorias con respecto del bimestre anterior, ¿Cuántas zanahorias cosechó?

Answers

Answer:

2.3X

Step-by-step explanation:

Working out the number of carrots she harvested based on the data given:

Percentage of carrot harvested compared to previous 2 months = 230%

Let the number of carrots harvested over the previous 2 months = x

Therefore, the number of carrots harvested this month will be :

Percentage harvested * number harvested over previous 2 months

(230% * X)

230/100 * X

2.3X

Therefore, the number of carrot harvested is: 2.3X

Answer:

Angle 2 & 4 = 72

Step-by-step explanation:

Angle 7 is corresponding to angles 3.

So, since we know angle 7 = 108, then angle 3 = 108.

Angle 3 is supplementary to angle 2, which means they add up to 180º.

So if angle 3 = 108.

Then:

Angle 2 + 108 = 180

Angle 2 = 72º.

Angle 2 & angle 4 are vertical angles, so they have the same measure. Therefore,. If angle 2 is 72º, then angle 4 has to also be 72º.
