What is -11 + 3(b + 5) = 7​

Mathematics
1 answer:
IRISSAK [1]2 years ago
7 0

Answer:

b=1

Step-by-step explanation:

\sf -11 + 3(b + 5) = 7

<u>First, let's regroup, terms,</u>

\sf 3(b+5)-11=7

<u>Add 11 to both sides,</u>

\sf 3(b+5)=7+11

<u>Simplify, 7+11 = 18,</u>

\sf 3(b+5)=18

<u>Now, divide both sides by 3,</u>

\sf b+5=\frac{18}{3}

<u>Simplify, 18/3 = 6,</u>

\sf b+5=6

Subtract 5 from both sides,

\sf b=6-5

\sf b=1

Hope it helps! :)

What is the largest value you can find in the interval (-5,-1)
zavuch27 [327]

(-5,-1) is aka -5<x<-1

This means -2 is the largest value you can find.

Perhaps that is if you are on a line graph, or if you are putting this on a line graph put an open circle (○) on -1 and -5 and draw a line in between the numbers. That's also if you are talking about real numbers and not integers this question is a bit too broad for me to actually figure out the true answer.

What is the GCF of M and M+1?
OleMash [197]

Step-by-step explanation:

Given that M is a positive integer, M + 1 is also a positive integer.

Since the difference between them is only 1, they cannot have a common factor above 1.

(For example if M is even, M + 1 must be odd and therefore they do not have a common factor 2 and so on)

Hence we conclude the GCF of M and M + 1 is 1.

If the radius and height of a cylinder are multiplied by 3, the lateral area of the cylinder is multiplied by
lutik1710 [3]
Answer:
The lateral area would be multiplied by 9

Explanation:
The lateral area of the cylinder can be calculated as follows:
lateral area = 2πrh
where:
r is the radius
h is the height

We are given that:
radius is multiplied by 3. This means that new radius is 3r
height is multiplied by 3. This means that new height is 3h

Substitute in the formula of the lateral area as follows:
lateral area = 2π(3r)(3h)
lateral area = 2*9*πrh
lateral area = 18πrh

Comparing the original lateral area with the new one, we would find that it is multiplied by 9

Hope this helps :)
