Step-by-step explanation:

Answer 2

Answer:

X=2, Y=1

X+Y=3

Step-by-step explanation:

-6x+12=0. first subtract 12 from each side

-6x=-12 now divide both sides by -6

X=2

4y+5=9. subtract 5 from each side

4y=4 divide both sides by 4

Y=1

2+1=3

Toby is trying to show his teacher why the product of two rational numbers is another
rational number. His first steps are shown. Which is the best method Toby could use to
proceed?
L
B

Answers

Using the concept of rational numbers, it is found that the best method Toby could use is a multiplication of fractions, as the product of two fractions(two rational numbers) is always a fraction(rational number).

-------------

A rational number, no matter if an integer, a finite decimal or a repeating decimal can always be represented by a fraction.The product of two fractions will always result in a fraction, as the numerator of the multiplication is the multiplication of the numerator of the factors, and same for the denominator.Thus, since the product of two fractions is always a fraction, the product of two rational numbers is always a rational number.

If r varies directly as t andr= -20 when t = 4, find r when t= -6.

Answers

Answer:

Step-by-step explanation:

t r = k/t Where k = constant of proportionality 132 = k/4 k = 4 x 132 k = 528 Formula r = 528/t Using formula r = 528/32 r = 16.5 Hope this helps :-) ...

The value of r should be considered as the 16.5 at the time when t = 4.

Calculation of the value of r:

Since we know that

t r = k/t

here k = constant of proportionality

So,

132 = k/4

k = 4 x 132

k = 528

Now

r = 528/t

r = 528/32

r = 16.5

hence, The value of r should be considered as the 16.5 at the time when t = 4.

angle adc = x

x+ 90 + 20 = 180                (triangke sum property)\

x = 180 - 110 = 70

angle bdc = 70/ 2 = 35          ( the median cuts the angle into 2)

2) cbd = x = 125

x + c + bdc = 180

x + 35 + 20 = 180

Number 13 Find the measures of angles 1, 2, and 3.

Answers

Answer:

1. 37

2. 26

3. 26

Step-by-step explanation:

Subtracting 63 from 180, you find the linear pair, being 117 which helps find an angle in the lower triangle. The sum of all angles is 180, and to find 2, you subtract the known angles ( 180-(37+117)) which equals 26. Knowing the shape is a parallelogram, and the opposite sides are parallel, we can say 2 and 3 are congruent through the alternate interior angles theorem. 1 is found through applying the same theorem.

The Correct Answer Is 4

Step-by-step explanation:

So if you have $12 and you can buy $3 with each box of envelopes, you think, how many times can 3 go into 12

count in your head, 3 6 9 12 therefore, ITS 4

here is your equation to match this:

3 x ? = 12

You probably already know this, but i simple way to figure this out is to flip the equation to

12/3 = ?

so from here you can tell that 3 goes into 12 4 times

so the equation is

3 x 4 = 12

Tayler's mom purchased a savings bond for Tyler. One year after it was purchased, the value of the savings bond was $156. If the value of the savings bond increases by 4% after one year, what was the value of the bond when Tyler's mom purchased it? Explain or show your reasoning.

Answers

Answer: The value of the bond when Tyler's mom purchased it = $150

Step-by-step explanation:

Let x= Purchasing price of the bond.

Given: Rate of increase in its value = 4% = 0.04

Value of bond after one year = x+ 4% of x

= x+0.04x

= 1.04x

One year after it was purchased, the value of the savings bond was $156.

[tex]\Rightarrow\ 1.04x = 156\\\\\Rightarrow\ x=\dfrac{156}{1.04}\\\\\Rightarrow\ x=150[/tex]

Hence, the value of the bond when Tyler's mom purchased it = $150
