the sum of the measures of the three angles in any triangle is 180 degrees the measure of the smallest angle of the CERN triangl
dmitriy555 [2]
I don't really know how to explain this but I know my answer is correct.

The smallest angle is 16
The medium size angle is 32
The largest angle is 132

If we let S, M, and L be variables, we can make the following equations
S = 1/2 M
M = 2 S
L = 8 S + 4
L + M + S = 180

If you plug in 16 for S, everything falls into place

Increase £761 by 77%. Give your answer to 2 DP
Ostrovityanka [42]

Answer:

<h2>£1346.97</h2>

Step-by-step explanation:

Step one

given the amount £761

we are asked to increase this amount by 77%

let us first find 77% of the amount £761

=77/100*761

=0.77*761

= £585.97

Step two:

Hence 77% of  £761 is £585.97

therefore the increase will be to add the two amounts together

=£585.97+£761

=£1346.97

There are 124 dogs and cats in Miss Mulero's backyard. There are eight more dogs than cats. What is the total number of dogs in
Genrish500 [490]

Answer:

There are 66 number of dogs in Miss Mulero's backyard.

Step-by-step explanation:

Let's set up equation for the given information.

Let there are 'd' number of dogs

and 'c' number of cats.

So, we can set up equation as

d+c=124

d=c+8

Let's solve the system of equations for 'd' and 'c'.

Substitute d as c+8 into the first equation then solve for 'c'

c+8+c=124

Combine like terms

2 c+8=124

Subtract both sides 8

2 c = 116

Divide both sides by 2.

c= 58

Plug in c as 58 into d=c+8

d=58+8

d=66

So, there are 66 number of dogs in Miss Mulero's backyard.

Find the solution set of the inequality<br> 8x−8≤−72.
Ierofanga [76]

Answer:

x≤-8

Step-by-step explanation:

When solving 8x-8≤-72, first add 8 to both sides of the inequality.

This leaves you with 8x≤-64.

Divide both sides by 8: 8x/8 and -64/8

This leaves you with x≤-8 as your solution.
