-3y - 7.8 = 9.6 solve these equation

Answers

Answer 1

y= -5.8 is the correct answer

Answer 2

Hopes this helps:

Answer: -5.8

1. Add 7.8 to both sides.
-3y = 9.6 + 7.8

2. Simplify 9.6 + 7.8 to 17.4.
-3y = 17.4

3. Divided both sides by -3.
Y= -17.4/3

4. Simplify 17.4/3 to 5.8.
Y= -5.8

for the page that starts with problems 13 and 14, it is mostly all the pythagorean therom which is a² + b² = c² (all you have to do is plug the numbers in)
in order to do this make sure you remember the longest side or the side directory across from the 90 degree angle is always c! a and b can be any of the other two sides (the legs) they just cannot be the longest side. Here’s problem 13:

a² + b² = c²
now we plug in all the numbers we have
a² + 3² = 5²
in this case i made the missing side “a”
now we must square the numbers
a² + 9 = 25
we can’t square a since we don’t have a number for it
a² + 9 = 25
-9 -9
——————
a² = 16
since we can’t add to get to the missing side like usual, we must subtract the other leg (b in this case) from c
now we must get rid of the square on the a, and because we can’t square it, the only that gets rid of a square is a square root (remember what you do to one side you must do to the other)

√a² = √16
if you don’t know how to square root on a regular calculator i suggest looking up a square root calculated (calculator soup is a pretty good reasource)
you only have to do actual math for the 16, so once you square root the 16, just cross out the square root and square on the a and you’ll get your answer
a = 4

Carlos cut StartFraction 5 Over 12 EndFraction of a yard of cloth into 5 pieces of equal length. What was the length of each piece of cloth? HELP?????????!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

1/12 yard

Step-by-step explanation:

From the above question:

5 pieces of equal length = 5/12 yards

1 piece of equal length = x yard

Cross Multiply

5 pieces × x = 1 piece × 5/12 yards

x = 1 piece × 5/12 yards/5 pieces

x = 5/12 ÷ 5

x = 5/12 × 1/5

x = 1/12 yard

The length of each piece of cloth is 1/12 yard

82, 85, 91, 86, 92, 78, 85, 86, 79, 82

Answers

Answer:

Median score = 82.5

Step-by-step explanation:

First, arrange the given data in an ordered manner. Thus:

55, 68, 72, 73, 75, 77, 78, 79, 82, 82, 83, 85, 85, 85, 86, 86, 87, 91, 92, 95

The median = the average of the 10th and 11th data

Median = (82 + 83) ÷ 2

Median = 165 ÷ 2

Medina = 82.5

c) Jasper and Emma are training for a marathon. Jasper runs 6 kilometers at a
time while Emma prefers to run in blocks of 3 kilometers. At the end of a
month, they realize that they have run same total number of kilometers. What
is the smallest number of kilometers that each must have run?

Answers

Answer:

The smallest number of kilometers that each must have ran is 6 km

Step-by-step explanation:

The distance Jasper prefers to run at a time = 6 km

The distance Emma prefers to run at a time = 3 km

The distance ran by Jasper at month end = The distance ran by Emma at the end of the month

The smallest number of kilometers that each must have ran is given by the lowest common multiple, LCM of 6 and 3 as follows;

The multiples of 6 are;

6 × 1 = 6, 6 × 2 = 12...

The multiples of 2 are;

3 × 1 = 3, 3 × 2 = 6...

∴ The LCM of which = 6

Therefore, the smallest number of kilometers that each must have ran = 6 km
