Answer:

-13

Step-by-step explanation:

Twice a number is 2h (h is the variable) so the equation is 12-2h=-14 and - 13 times 2 is -26 so the equation is now 12-26=-14

What is the approximate distance between the points (-5,1) and (-2,3) on a coordinate grid? Show me an example please

yaroslaw [1]

Answer:

$d=\sqrt{13}\ units$ or $d=3.61\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-5,1)\\E(-2,3)$

substitute the values

$d=\sqrt{(3-1)^{2}+(-2+5)^{2}}$

$d=\sqrt{(2)^{2}+(3)^{2}}$

$d=\sqrt{13}\ units$

$d=3.61\ units$

Jerry scored 581 points by collecting 7 coins. In all, how many coins does Jerry have to collect to score a total of 996 points?

charle [14.2K]

Answer:

12 coins

Step-by-step explanation:

Points scored by collecting 7 coins = 581

Number of coins required to collect 996 points

Let Number of coins = c

7 coins = 581 points

c coins = 996 points

Cross multiply :

581 * c = 996 * 7

581c = 6972

Divide both sides by 581

581c / 581 = 6972 / 581

c = 12

Hence, number of coins required to collect 996 points is 12
