3 consecutive integers for 273
a_sh-v [17]

Answer:

90, 91 and 92

Step-by-step explanation:

Given

Consecutive integers = 273

Required

Find the integers

The question seem to be incomplete. However, I'll assume we're dealing with sum.

Let the smallest integer be y.

So,

y + y + 1 + y + 2 = 273

Collect like terms.

y + y + y = 273 - 2 - 1

3y = 270

Divide both sides by 3

y = 90

Hence, the integers are 90, 91 and 92

(a) A tram moved downward 72 meters in 8 seconds at a constant rate. What was the change in
Alex787 [66]

Answer:

a) 9 meters.

b) The total change in temperature was of 288ºC

Step-by-step explanation:

Both these questions can be solved using rules of three.

a) 72 meters in 8 seconds. How many meters it changes each second(in 1 second)?

8s - 72m

1s - x m

8x = 72

x = \frac{72}{8}

x = 9

9 meters.

b) In 1 hour, heated by 6ºC. How much in total during 48 hours?

1h - 6ºC

48h - xºC

x = 48*6

The total change in temperature was of 288ºC

Determine whether the statement is true or false. If the statement is false, make the necessary change(s) to produce a true stat
SVEN [57.7K]
7x-5=0
7x=5
x=5/7

Your answer was wrong. When you transpose (shift) the -5 to right side the sign should change and become a positive 5.
I don’t know if that makes sense.
In maths, when you move a number over the equal sign whether it’s to the right or the left of the equal sign the sign infront if the number must change as well.

Example:
2x +4=0
2x= -4
x=-2
