What is 25m+100-24m-75=68<br> Please explain

Mars2501 [29]

Let's solve your equation step-by-step.

25m+100−24m−75=68

Step 1: Simplify both sides of the equation.

25m+100−24m−75=68

25m+100+−24m+−75=68

(25m+−24m)+(100+−75)=68(Combine Like Terms)

m+25=68

m+25=68

Step 2: Subtract 25 from both sides.

m+25−25=68−25

m=43

Answer:

m=43

At a pet store, one fifth of the animals are cats and three-fourth are fish. There are 40 animals at the pet store. How many are

dybincka [34]

Answer:

2 animals

Step-by-step explanation:

Number of animals=40

Fraction of fish=3/4

=>number of fish=3/4*40=30

Fraction of cats=1/5

=>number of cats=1/5*40=8

Animals which are not cats or fish are=total number of animals-(number of cats + number of fish)

Animals which are not cats or fish=40-(8+30)

40-38

2 animals

The vertex angle of an isosceles triangle measures 42°. A base angle in the triangle has a measure given by (2x + 3)°. What is t

Vsevolod [243]

<u>Part a) </u>

we know that

An isosceles triangle has two base angles that are congruent

The sum of two base angles plus the vertex angle is equal to $180$ degrees

so

In this problem

$vertex\ angle=42\°$

$base\ angle=(2x+3)\°$

$42\°+2*(2x+3)\°=180\°$

Solve for x

$42+4x+6=180$

$4x=180-48$

$x=132/4$

$x=33\°$

therefore

<u>the answer part a) is</u>

the value of x is $33\°$

<u>Part b)</u> What is the measure of each base angle?

we know that

$base\ angle=(2x+3)\°$

we have that

$x=33\°$

substitute the value of x in the equation

$base\ angle=(2*33+3)\°$

$base\ angle=69\°$

therefore

<u>the answer part b) is </u>

the measure of each base angle is $69\°$
