Answer:

What must be true is that the three angles must be equal to one another

Step-by-step explanation:

Here, we want to know what must be true of the three angles if the pieces must be parallel

What must be true of the angles is that they must be corresponding to each other

If they are corresponding, that means the angles are congruent

Given that they are congruent, it simply means that they are all equal to each other

Which simplified fraction is equal to 0.53? 1) 24/45 2) 8/15 3) 48/90 4) 5/9

Shalnov [3]

To express a decimal number (with a finite decimal expression) in a fraction, you work like this: the numerator is the number without decimale separator (you simply pretend it's not there), while the denominator will be $10^n$ , where n is the number of digits after the decimal separator.

So, in your case, the number without decimal separator is 53, and you have two digits after the decimal separator, so the fraction will be

$0.53 = \cfrac{53}{10^2} = \cfrac{53}{100}$

which is irreducible.

Find the base of a parallelogram with a slant height of 7cm and an perimeter of 63 cm2

vlada-n [284]

Base of parallelogram b = 24.5 cm

Step-by-step explanation:

We are given:

Perimeter =P= 63 cm^2

Slant Height =a= 7 cm

Base of Parallelogram =b= ?

The formula used is:

$Perimeter = 2(a+b)$

where a is height and b is base

Putting values:

$Perimeter = 2(a+b)\\63=2(7+b)\\63=14+2b\\2b=63-14\\2b=49\\b=\frac{49}{2}\\b=24.5$

So, Base of parallelogram b = 24.5 cm

Solve the system of equations by substitution. Show your work in the sketch and write your answer as an ordered pair.

Ede4ka [16]

Let's solve your system by substitution.

−3x+y=−2;y=4x

Rewrite equations:

y=4x;−3x+y=−2

Step: Solvey=4xfor y:

y=4x

Step: Substitute4xforyin−3x+y=−2:

−3x+y=−2

−3x+4x=−2

x=−2(Simplify both sides of the equation)

Step: Substitute−2forxiny=4x:

y=4x

y=(4)(−2)

y=−8(Simplify both sides of the equation)

Answer:

x=−2 and y=−8

What is 3k +2 ( 5k - 3) = 7

polet [3.4K]

Answer:

k= -0.2

Step-by-step explanation:

3+2(5k-3)=7 (original)

3+10k-6=7 (distribute 2 in (5k-3))

9+10k=7 (combine like terms 3+-6)

10k=-2 (subtract 9 on both sides to isolate k)

k=-0.2 (divide 10 on both sides to get you're answer/isolate k)
